雅思a類(lèi)閱讀資料——六個(gè)壞習(xí)慣將毀掉你的睡眠
If you equate getting older with needing—or getting—less sleep, here’s a wake-up call: It's not true! “The majority of us require between seven and nine hours of shut-eye a night," says Robert Oexman, D.C., director of the Sleep to Live Institute. “And there’s little reason—whether you’re 55 or 80—not to get it.” Barring disease, medication and pain (all legitimate sleep interrupters), if patients complain of bad sleep, Dr. Oexman looks at their nighttime habits, where the problem almost always resides.
如果你認(rèn)為人慢慢長(zhǎng)大變老,需要或得到的睡眠更少,那我來(lái)提醒你吧,不是這樣的!睡眠與生命研究所所長(zhǎng),脊骨神經(jīng)科醫(yī)師羅伯特·歐克斯曼說(shuō)道:“大多數(shù)人每晚需要7-9小時(shí)的睡眠時(shí)間。無(wú)論你是55還是80歲,都應(yīng)該做到這一點(diǎn)。”疾病、藥物和疼痛除外(這些都可能會(huì)干擾睡眠),如果病人抱怨睡不好覺(jué),歐克斯曼醫(yī)師會(huì)查看其晚間生活習(xí)慣來(lái)發(fā)現(xiàn)問(wèn)題所在。
So, how are you sabotaging your z-z-z-z-z’s?
所以,你是怎樣破壞自己的睡眠的呢?
Bad Habit #1: Watching TV until you fall asleep?
壞習(xí)慣一:看電視看到睡著
Why It Disrupts Sleep: It has nothing to do with what you watch—Downton Abbey isn’t a better pre-sleep choice than Dog the Bounty Hunter. Rather it’s the exposure to TV’s bright light that’s the culprit. Artificial bright light after dusk not only enhances alertness, but also delays the production of melatonin, a sleep-inducing hormone. So even if you nod off (in front of the TV, for example), you probably won’t stay asleep for long.
為什么會(huì)影響睡眠:這和你看什么節(jié)目沒(méi)有任何關(guān)系,因?yàn)椤短祁D莊園》并不是比《賞金獵人》更好的睡前節(jié)目。反而是暴露在電視強(qiáng)光下才是影響你睡眠的罪魁禍?zhǔn)?。天黑后的人造?qiáng)光不僅讓人增加警惕性,而且會(huì)延遲體內(nèi)睡眠荷爾蒙——褪黑素的生成。所以即使你打盹了(比如在電視機(jī)前),你很可能也睡不了多久。
EZZZ Fix: An hour before bedtime, treat yourself like a baby: a warm bath, followed by a quiet activity in dim light—meditation, journal writing, reading. But no reading or writing on your computer before bed or in the middle of the night. (Almost half of the respondents in the AOL Email Addiction survey admitted to checking email during the night. If that’s you, keep technology out of the bedroom.)
解決方法:睡前一小時(shí),讓自己像嬰兒一樣:洗個(gè)熱水澡,在暗淡的燈光下做些安靜的事情-冥想,寫(xiě)日記,閱讀。但是睡前或者半夜絕對(duì)不能在電腦上閱讀或者寫(xiě)東西。(幾乎一半?yún)⑴c美國(guó)在線電子郵件上癮調(diào)查的人們承認(rèn)晚間會(huì)查看電子郵件。如果你也是這樣,那么記得把高科技關(guān)在臥室外面吧。)
Bad Habit #2: Sleeping with Fido
壞習(xí)慣二:抱狗狗睡覺(jué)
Why It Disrupts Sleep: While animal-lovers argue the emotional benefits of sharing a pillow with their pets, research shows that pets can contribute to less than sound sleep. How? “Pets have different circadian rhythms than humans," says Oexman. “They sleep most of the day, and they shift a lot when sleeping—they get comfortable, then they move. This goes on all night, and whether you admit it or not, it interrupts your ability to get the level of sleep needed to feel rested." (As for pet dander and allergies—sneezing and wheezing are not great sleep enhancers.)
為什么會(huì)影響睡眠:動(dòng)物愛(ài)好者認(rèn)為和寵物一起睡覺(jué)有情感上的益處,然而研究表明寵物實(shí)際上會(huì)影響睡眠。這是怎么回事呢?“寵物和人有著不同的生理節(jié)律,”歐克斯曼說(shuō),“他們每天大多數(shù)時(shí)候都會(huì)睡,睡覺(jué)的時(shí)候經(jīng)常動(dòng)-他們覺(jué)得舒服,然后就會(huì)動(dòng)。整晚都會(huì)這樣,而且無(wú)論你承認(rèn)與否,你都會(huì)不知不覺(jué)被影響而達(dá)不到自己需要的睡眠程度。(至于寵物皮屑和各種過(guò)敏導(dǎo)致的打噴嚏和喘息都是會(huì)影響睡眠的因素。)
EZZZ Fix: For two weeks, put your pooch or cat in a crate outside your closed bedroom door. When your pet can sleep quietly in the crate, move the crate inside your room for another two weeks. When the crate training is complete, try letting the dog or cat sleep in his own bed near your bed. Discourage all attempts to jump on your bed and reward all successes for staying in his own bed. (Caveat: Plan on interrupted sleep for a few weeks.)
雅思a類(lèi)閱讀資料——最適合春天吃的美食
New research suggests some foods have the power to guard skin from the damage caused by the sun's UV radiation. While a salad is no substitute for sunblock, these healthy foods could add inner protection against sunburn and wrinkles at the cellular level.
新的研究發(fā)現(xiàn)表明某些食物可以幫助肌膚免受陽(yáng)光紫外線的侵害。但是,一盤(pán)沙拉并不能代替防曬霜,這些健康食物可以加強(qiáng)身體內(nèi)在機(jī)能,保護(hù)皮膚不受侵害并延緩細(xì)胞衰老。
Citrus Fruits 柑橘類(lèi)水果
Citrus fruits have the potent ingredient limonene, associated with a whopping 34 percent lower risk of skin cancer in one University of Arizona study of 470 women and men.
柑橘類(lèi)水果含有豐富的檸檬烯。亞利桑那大學(xué)對(duì)470位女性和男性進(jìn)行的研究表明,檸檬烯可以將患皮膚癌的風(fēng)險(xiǎn)降低34%
Green tea 綠茶
This delicately flavored tea is full of antioxidants called EGCGs. Among their health-promoting capabilities: EGCGs stopped genetic damage in human skin cells exposed to UV light in one University of Wisconsin study.
綠茶所含有的抗氧化劑叫做茶多酚。威斯康星大學(xué)的研究表明茶多酚可以使暴露在紫外線下的肌膚免受基因損害。
Carrots 胡蘿卜
Carrots—or any other red, yellow, and orange fruits and vegetables—are packed with carotenoids, and studies show they reduce sunburn intensity.
胡蘿卜或者任何紅色,黃色及橙色水果和蔬菜都富含類(lèi)胡蘿卜素,研究表明這些果蔬可以降低日曬強(qiáng)度。
Red Peppers 紅椒
Like carrots, red peppers are also especially helpful in reducing sunburn intensity.
和紅蘿卜一樣,紅椒在降低日曬強(qiáng)度方面有顯著效果。
Spinach 菠菜
Leafy greens, like dark green lettuce, spinach, kale, and Swiss chard, are top sources of the antioxidants lutein and zeaxanthin, which halted cell growth prompted by UV light in animal studies.綠葉蔬菜,如綠色萵苣,菠菜,甘藍(lán)菜和唐萵苣均含有非常豐富的抗氧化劑葉黃素和玉米黃素,這些抗氧化劑可以阻止紫外線引起的細(xì)胞生長(zhǎng)。
Salmon 三文魚(yú)
This fish is a great source of oils rich in omega-3 fatty acids. In a small British study, fish oils guarded against sunburn and DNA changes that can lead to cancer.
三文魚(yú)的魚(yú)油富含豐富的脂肪酸。研究表明魚(yú)油可以預(yù)防易引發(fā)癌癥的曬黑曬傷和DNA改變。
Walnuts 核桃
Like salmon, walnuts are high in essential fatty acids that could guard against sunburn.
和三文魚(yú)一樣,核桃也富含有豐富的人體必需脂肪酸,而這類(lèi)脂肪酸可以抵御曬傷曬黑。
利用雅思閱讀材料的3大技巧
一、真題為主,其他材料為輔
很多考生,尤其是剛接觸雅思的考生,還沒(méi)開(kāi)始備考,先囫圇吞棗買(mǎi)了各種各樣的書(shū),其實(shí)后期也未必真用得上。所以如果是以備考為目的話,最好的方式還是從最直接的考試材料入手最為妥當(dāng)。市面上的出的輔導(dǎo)類(lèi)用書(shū)很多,但最貼近考試的還是劍橋雅思真題。劍橋雅思真題系列,是劍橋大學(xué)考試委員會(huì)出版的,這可是考試出題方,實(shí)打?qū)嵉恼骖}。通過(guò)做真題,可以了解出題方式、考試題型等等內(nèi)容,對(duì)備考非常有幫助。同時(shí)真題不光可以用來(lái)自測(cè),還是用來(lái)精讀的材料??梢哉f(shuō),真題是必備備考資料。
說(shuō)到其他輔導(dǎo)材料(這里不包含備考雅思考試的技巧類(lèi)用書(shū)),平常時(shí)候該讀什么保持閱讀量,這也讓很多考生撓頭。雅思閱讀考試的文章以大眾題材為主,涉及到教育、經(jīng)濟(jì)、科技、生物、醫(yī)學(xué)、環(huán)境、地質(zhì)、能源等各方面問(wèn)題,但不涉及專(zhuān)業(yè)性過(guò)強(qiáng)的文章,以免造成不同學(xué)生知識(shí)儲(chǔ)備不同所產(chǎn)生的優(yōu)劣勢(shì)。甚至有些內(nèi)容來(lái)自于日常生活,所以考生不必刻意記住很多艱深的生僻專(zhuān)業(yè)術(shù)語(yǔ)。因此就材料選擇來(lái)說(shuō),國(guó)際上比較知名的雜志都是可以利用的閱讀材料。
提示:閱讀練習(xí)中也盡量有時(shí)間觀念,保持適度緊張感,養(yǎng)成良好的習(xí)慣。同時(shí),不要刻意追求讀的“多”,總結(jié)自己閱讀中的問(wèn)題才更有用。
二、詞匯的累積
看了第一部分,有的人會(huì)說(shuō),我才高中,很多雅思詞匯都比較難,做真題都看不懂。是的,這第二點(diǎn)就要說(shuō)這個(gè)問(wèn)題了。詞句篇,詞匯是基礎(chǔ),同雅思寫(xiě)作一樣,閱讀也同理。沒(méi)有一定的詞匯量對(duì)于閱讀來(lái)說(shuō)比較困難,所以扎扎實(shí)實(shí)累積詞匯、背單詞,這還是很重要的。
三、把握出題者意圖
這一點(diǎn)是個(gè)說(shuō)難不難說(shuō)易不易的方法,需要多做幾篇來(lái)找找感覺(jué)。但如果能對(duì)上下文之間的關(guān)聯(lián)有很好的理解,又能把握文章的大體脈絡(luò),無(wú)疑對(duì)解題有莫大幫助。
以上就是雅思a類(lèi)閱讀資料及用法的講解的全部?jī)?nèi)容,雅思閱讀材料的用處還是在于從長(zhǎng)期來(lái)看,提高整體的英語(yǔ)閱讀能力。如果考生的備考期較短,在相應(yīng)的閱讀材料的選取上,可以更偏向于應(yīng)試找一些帶題的閱讀去做。
