Parenting brings fathers more joy than it does mothers,according to a new study.The research examined three studies 26 more than 18,000 participants.Across all three,parenthood was 27 with more positive wellbeing outcomes for dads than for mums.
So why are fathers happier than mothers?“Fathers may fare beter than mothers in part dueto how theyspend time with their children,”said lead author Katherine Nelson-Coffey.In one study,the authors 28 that dads were more likely to take“playing”as an 29 activity both when caring for their kids and spending time with their kids.“Playing with their children likely offers parents opportunities to experience positive feelings and 30 closeness with their children,”they say.
Fathers also did better than menwithout kids,reporting greater happiness,life satisfaction,and fewer 31 symptoms.They also reported greater connectedness and autonomy(自主) .For mums, 32 ,compared to women without children,the results weren't quite as positive.Mums reported greater autonomy,but also"greater trouble"and fewer positive 33 .
Mums reported happier moods while interacting with their kids,compared to other experiences,but not while engaging 34 in childcare.“This difference suggests that how mothers and fathers spend time with their children mighthave important 35 for their wellbeing,”the authors write.They suspect that mums may be less happy than dads because they're more likely to have higher expectations about parenthood.As such,they're more likely to be“l(fā)et down”by the experience.

Section B
Directions: In this section,you are going to read a passage with ten statements attached to it.Each statement contains information given in one of the paragraphs.Identify the paragraph from which the information is derived.You may choose a paragraph more than once.Each paragraph is marked with a letter.Answer the questions by marking the corresponding letter on Answer Sheet 2.
Learning to say no
A)Notdoing something will always be faster than doing it.This philosophy applies in many areasof life For example,there is nomeeting that goes faster than not having a meeting at all.This is not to say you should never attend another meeting,but the truth is that we say“yes"to too many things wedon't actually want to do.
B)How often do people ask you to do something and you just reply,“Sure.”Three days later,you're overwhelmed by how much is on your to-do list.We become frustrated by our obligations eventhough wewere the ones who said“yes”to them in the first place.Evenworse,people will occasionally fight to do things that waste time.You don't have to do something just because it exists.It's worth asking if things are necessary.Many of them are not,and a simple“no”willbe more productive than whatever work the most efficient person can cope with.But if the benefits of saying“no”are so obvious,then why do we say“yes”so often?
C)We say“yes”tomany requests not because we want to do them,butbecause we don't want to be seen as rude or unhelpful.Often,we have to consider saying“no”to someone we will interact with again in the future—our co-worker,our spouse,our family and fricnds.Saying “no”to our superiors at work canbe particularly difficult.In these situations,I like the approach recommended in Essentialism by Greg McKeown.He writes,“Remind your superiors what you would be neglecting if you said ‘yes'and force them to deal with the trade-off.For example,if your manager comes to you and asks you to do X,you can respond with‘Yes,I'm happy to make this the priority.Which of theseother projects should I deprioritize to pay attention to this new project?'”
D)Collaborating with others is an important element of life.The thought of straining the relationship outweighs the commitment of our time and energy.For this reason,it can be helpful to be gracious in your response.Do whatever favors you can,and be warm-hearted and direct when you have to say no.But even afterwe have accounted for these social considerations,manyofus still seem to do a poor job of managing the trade-off between yes and no.We find ourselves over-committed to things that don't meaningfully improve or support those around us,and certainly don't improve our own lives.
E)Perhaps one issue is how we think about the meaning ofyes and no.The words “yes”and“no”get so often used in comparison with each other that it feels like theycarry equal weight in conversation.In reality,they're not just opposite in meaning,but of entirely different magnitudes in commitment. When you say“no",you're only saying“no"to one option.When you say“yes”,you're saying“no”to every other option.I likehow economist Tim Harford put it,“Every time we say *yes'to a request, we're also saying‘no'to anything else we might accomplish with the time.”O(jiān)nce you're committed to something,you've already decided how that future block of time will be spent.In other words,saying “no”saves you time in the future.Saying“yes”costs you time in the future.“No”isa form of time credit.You retain the ability to spend your future time however you want.“Yes”is a form of time debt.Youhave to pay back your commitment at some point.
F)“No"is a decision.“Yes”is a responsibility.Saying“no”is sometimes seen as a luxury that only those in power can afford.And it's true:turning down opportunities is casier when you can fall back onthe safety net provided by power,money,and authority.But it's also true that saying“no”is not merely a privilege reserved for the succesful.It's also a strategy that can help you become successful.Saying “no”is an important skill to develop at any stage of your career because it retains the most important asset in life:your time.As investor Pedro Sorrentinoput it,“If you don't guard your time,people will steal it from you.”You need to say “no”to whatever isn't leading you toward your goals.
G)Nobody embodied this idea better than Steve Jobs,who said,“People think focus means saying‘yes to the thing you've got to focus on.But that's not what it means at all.It means saying‘no'to the hundred other good ideas that thereare.You have to pick carefully.”Jobs had another great quote about saying“no”:“I'm actually as proud of the thingswe haven't done as the things I have done.Innovation is saying*no'to 1,000 things.”
H)Over time,as you continue to improve and succeed,your strategy needs to change.The opportunity cost of your time increases as you become more successful.At first,you just eliminate the obvious distractions andexplore the rest.As your skills improve and you learn to separate what works from what doesn't,you have to continually increase your threshold for saying“yes".You still need to say “no”to distractions,but you also need to learn to say“no”to opportunities that were previously good uses of time,soyou can make space for better uses of time.It's a good problem to have,but it can be a tough skill to master.
I)What is true about health is also true about productivity:an ounce of prevention is worth a pound of cure.More effortis wasted doing things that don'tmatterthanis wasted doing thingsinefficiently.And if that is the case,elimination is a more useful skill than optimization.I'm reminded of the famous Peter Drucker quote,“There is nothing so useless as doing cfficiently that which should not be done at all.”
36.People often grant a requestjust because they want to appear polite and helpful.
37.It's noeasy job learning to say“no"to opportunities that were once considered worth grasping.
38.When you decline a request,you are saving your future time.
39.People sometimes struggle to do things that are simply a waste of time.
40.Doing efficiently what is not worth doingis the most useless effort.
41.It is especially difficult for people to decline to do what their superiors ask them to do
42.People agree to do too many things they are in factunwilling to do.
43.According to one famousentrepreneur,innovation means refusal to do an enormous number of things.
44.It is an essential aspect of life to cooperate with other people.
45.Refusing a request is sometimes seenas a privilege not enjoyed by ordinary people.

Section C
Directions: There are 2 passages in this section.Each passage is followed by some questions or unfinished statements.For each of them there are four choices marked A),B),C)and D).You should decide on the best choice and mark the corresponding letteron Answer Sheet 2 with a single line through the centre.
Passage One
Questions 46 to 50 are based on the following passage.
We're eating more fish than ever these days.At around 20 kilograms per person global fish consumption is now more than twice what it was in the 1960s.What's really remarkable,though,is where that fish comes from.
For the first time in human history,most of our aquatic(水產(chǎn)的)food now comes from farming rather than fishing.
People ate around 73 million tonnes of farmed fish—just more than half of the volume of fish that humans consumed—in 2014.That's out of a total fish supply of 167 million tonnes;the remaining 20 million or sotonnes go into things like animal feed and medical products.
To keep eating fish at the current rate,we're definitely going to need to keep aquaculture(水產(chǎn)養(yǎng)殖)developing.That's because the volume of fish caught in the wild has leveled off since the 1990s.
Back in 1974,only 10% of marine fish stocks had been overfished.Now,more than three-tenths are. Only a tenth of our oceans'fish stocks could sustain heavier fishing than current levels.
But while catchings at sea have suffered,fish-farming has been growing at a fast rate.A lot of that is coming from China,which produces 60% of the world's farmed fish.In fact,some 35 countries,including China,now produce more farmed than wild-caught fish.
This shift toward aquaculture isn't just good for ensuring salmon(三文魚)on your plate;it's also crucial to ensuring food security and sustainability.By 2050,the world will need to feed an estimated9.7 billion people.They'll have to get their protein somewhere.However,raising cattle,pigs,and other land-based animals requires vast sums of grain and water.For example,pound for pound,beef requires 15 times more feed to raise than carp,a freshwater fish farmed all over Asia.That grain—and the water needed to grow it—could be consumed by people instead.
However,aquaculture is no silver bullet.In some southeast Asiancountries,shrimp farming does disastrous damage to marine ecosystems.Despite these problems,however,shrimp continues to be among the mostpopular seafoods worldwide.
46.What does the author say is remarkable about the fish we eat?
A)They reproduce quickly.
B)They are mostly farmed.
C)They have become as important as grain.
D)They have a longer history than humans.
47.What do we need to do if we keep consuming fish at the currentrate?
A)Increase the fishing volume considerably.
B)Develop more advanced fishing technology
C)Enlarge the marine fish stocks effectively.
D)Expand the scale of fish-farming continuously.
48.What does the author say aboutChina in terms of aquaticfood?
A)It places increasing emphasis on fishing now.
B)It boasts of the world's largest fishing stocks.
C)It raises more fish than caught from the wild.
D)It supplies 60% of the world's fish products.
49.Why doesthe author say aquaculture is so important these days?
A)It is a must for feding the world's fast-growing population.
B)It proves a reliable source of protein for humans and animals.
C)It isessential to maintaining both mental and physical health.
D)It ensures a balanced healthy diet for people the world over.
50.What does the author imply by saying aquaculture is no silver bullet?
A)Shrimp-farmingis a riskybusiness.
B)Fish-farming will not be sustainable.
C)Fish-farming may cause serious problems too.
D)Shrimp-farming can become quite expensive.
答案解析
46.【定位】由題干中的remarkable about the fish we eat定位到第一段最后一句和第二段。
B)【精析】細節(jié)辨認題。第一段最后一句提到，真正值得注意的是這些魚的來源。第二段接著指出，我們大部分的水產(chǎn)食物來自養(yǎng)殖而非捕撈。由此可知，我們吃的大部分的魚是養(yǎng)殖的，故答案為B)。
47.【定位】由題干中的keep consuming fish at the current rate定位到第四段第一句。
D)【精析】推理判斷題。定位句提到，為了保證魚肉攝入量一直處于現(xiàn)如今的水平，我們肯定需要讓水產(chǎn)養(yǎng)殖業(yè)不斷發(fā)展。通過推斷可知，讓水產(chǎn)養(yǎng)殖業(yè)不斷發(fā)展的舉措肯定包括擴大養(yǎng)殖規(guī)模，故答案為D)。
48.【定位】由題干中的China和aquatic food定位到第六段最后一句。
C)【精析】細節(jié)辨認題。定位句指出，事實上，包括中國在內(nèi)的約35個國家，現(xiàn)如今的養(yǎng)殖魚產(chǎn)量超過了野生捕撈量。C)選項中的raises more..than caught from the wild對應定位句中的produce more farmed than wild-caught,故答案為C)。
49.【定位】由題干中的aquaculture is so important定位到倒數(shù)第二段。
A)【精析】推理判斷題。定位段提到，這種向水產(chǎn)養(yǎng)殖的轉(zhuǎn)變對于確保食品安全性和可持續(xù)性至關(guān)重要。到2050年，全球?qū)⑿枰B(yǎng)活大約97億人。他們需要從某些地方獲取蛋白質(zhì)。隨后用牛和鯉魚的例子來說明，養(yǎng)魚比養(yǎng)牛更劃算。結(jié)合段落大意可以推斷出，發(fā)展水產(chǎn)養(yǎng)殖對于養(yǎng)活迅速增長的人口更有利，故答案為A)。
50.【定位】由題干中的aquaculture is no silver bullet定位到最后一段。
C)【精析】細節(jié)辨認題。最后一段第二句指出，在一些東南亞國家，蝦類養(yǎng)殖對海洋生態(tài)造成了災難性的破壞。由此可知，水產(chǎn)養(yǎng)殖也有負面影響，故答案為C。
Passage Two
Questions 51 to 55 are based on the following passage.
In 2020,the Nobel Peace Prize was awarded to the World Food Programme(WFP).
Why a Nobel Prize for the WFP,and why now?In 2019,the WFP assisted nearly 100 million people in 88 countries.It isthe safety net for those who fall off the edge of existence.It is a response to solving the problem of food instability.Its Nobel Prize remindsus all of the moral hazard in imagining that the poor and vulnerable are somebody else's problem.
The WFP has been around since 1961 and hasbeen the global coordinator of nationally based efforts to avoid disasters with food aid.Despite decades of effort to eliminate hunger,the latest estimate is that about 11% of people on the planet(about 820 million people)aresuffering daily undernourishment. Progress at reducing undernourishment has stopped despite gains through the 1990s and 2000s.
Developed countriessometimes offer food and aid to developing ones,but at a price.One American philosopher stated that addressing the needs of the poor and vulnerable is about morethan money—it is mostly about creating conditions under which prosperity and opportunity can thrive.When aid is offered with heavy conditions attached,like loan repayment or food for resources,it often widens the gap between rich and poor and sustains the old world order.This is why the work of the WFP is so vital.
The scientific community,however,can provide a helping hand to the WFP.By sharing knowledge of agriculture and climate with peers in countries most vulnerable to poverty and hunger,scientists can help reduce these problems.By making its voice heard,science can lead by example.The ability to overcome food shortages thatmust be built into some of the poorest countries will notcome from loans from wealthy countries,which may have food problems of their own,or world economic institutions.This ability will be built upon self-confident people using open and shared scientific knowledge topull themselves out of their misery.
51.What does the WFP's winning of the Nobel Peace Prize makeus realize?
A)More and morepeople inthe world are suffering from starvation.
B)All of us can be affected by food instability one way or another.
C)It is hazardous to leave millions of people poor and vulnerable.
D)It is morally wrong to think helping the poor is not our business.
52.What do welearn about the WFP'scffort to eliminate hunger?
A)It has ensured a sufficient food supply to millions.
B)It is still far from its goal despite the progress made.
C)It has done a good job in combating natural disasters.
D)It is preventing starvation occurring on a global scale.
53.What will happen when food aid is offered at a price?
A) The rich will become richer and the poor poorer.
B) More people will be willing to join in the effort.
C) More food will be made available to the needy.
D) The relief effort will be rendered less sustainable.
54.How can scientists help cope with poverty and hunger?
A) By collaborating closely with world economic institutions.
B) By sharing expertise with peers in poverty-stricken nations.
C) By setting up more food research programs in developing countries.
D) By building self-respect in people suffering from undernutrition.
55.What message does the author try to convey at the end of the passage?
A) Wealthy nations should solve their own food problems first.
B) Rich countries should be more generous in providing food aid.
C) Poor nations should enhance their own ability to solve their food shortages.
D) World economic institutions should play a bigger role in fighting hunger.
答案解析
51.【定位】由題干中的the WFP's winning of the Nobel Peace Prize定位到第二段最后一句。
D)【精析】細節(jié)辨認題。定位句指出，它的諾貝爾獎提醒我們所有人，把窮人和弱勢群體當成別人的問題是一種道德危機。“它”指的是前文提到的世界糧食計劃署，D)選項中的morallywrong對應定 位句中的moral hazard。由此可知，答案為D)。
52.【定位】由題干中的 the WFP's effort to eliminate hunger 定位到第三段。
B)【精析】推理判斷題。定位段提到，世界糧食計劃 署自1961年成立以來，一直是各國通過糧食援助 避免災難的全球協(xié)調(diào)機構(gòu)。盡管為消除饑餓付出了幾十年的努力，但據(jù)最新估計，地球上約有11%的人(約8.2億人)每天營養(yǎng)不良。盡管在20世紀 90年代和21世紀初取得了一些進展，但在減少營養(yǎng)不良方面的進展已經(jīng)停止。由此推斷可知，世界糧食計劃署在消除饑餓上取得了一些進展，但距離目標還很遠，故答案為B)。
53.【定位】由題干中的food aid is offered at a price定位到第四段倒數(shù)第二句。
A)【精析】細節(jié)辨認題。定位句指出，如果援助附帶沉重的條件，如償還貸款或以糧食換資源，這往往會擴大貧富差距，維持舊的世界秩序。由此可知，如果以一定代價提供糧食援助，會擴大貧富差距，即可能會導致富人變得更富，窮人變得更窮，故答 案為A)。
54.【定位】由題干中的 scientists help cope with poverty andhunger定位到第五段第二句。
B)【精析】推理判斷題。定位句提到，通過與最容易遭受貧困和饑餓的國家的同行分享農(nóng)業(yè)和氣候知識，科學家可以幫助減少這些問題。B) 選項中的 expertise是對定位句中knowledge of agriculture and climate的總結(jié)，由此可推斷，科學家可以通過 與貧困國家的同行分享專業(yè)知識來幫助解決貧困和饑餓問題，故答案為B)。
55.【定位】由題干中的at the end of the passage定位到最后一段最后一句。
C)【精析】推理判斷題。定位句指出，這種能力將建立在自信的人們利用開放和共享的科學知識使自己擺脫痛苦的基礎(chǔ)上。結(jié)合前文可知，“這種能力”指的是最貧窮的國家必須具備克服糧食短缺的能力。由此推斷可知，作者認為貧窮國家應該提高自己解決糧食短缺的能力，故答案為C)。
