譯文
但是大多數(shù)專家都認同，為了讓教職員及學(xué)生接觸到其學(xué)科的最新發(fā)展，一些科研活動是必要的。
點睛
that引導(dǎo)的是agree的賓語從句。be essential to do sth.意為“做某事絕對重要，必不可少”。如：Good food and plenty of exercise are essential to lead a healthy life. 要想健康地生活，吃得好并進行大量的鍛煉是非常重要的。
keep in touch with sth.此處意為“獲得某方面的最新信息（知識等）”。如：We are able to keep in touch with events of the outside world via the Internet. 通過互聯(lián)網(wǎng)我們能夠了解到外界發(fā)生的事。
考點歸納
有關(guān)touch的常見短語還有：
be/get/keep in touch with sb.意為“與某人有／獲得／保持聯(lián)系”。如：
I'm still in touch with my friends from college. 我和大學(xué)的朋友還有聯(lián)系。
They're trying to get in touch with the manager. 他們正設(shè)法和經(jīng)理取得聯(lián)系。
Let's keep in touch. 我們要保持聯(lián)系。
be out of touch和lose touch都意為“失去聯(lián)系”，后接介詞with也都可以指“不再了解”。如：
I'm out of touch with many old friends now. ＝I've lost touch with many old friends. 我現(xiàn)在和很多老朋友都失去了聯(lián)系。
You are out of touch with real life. ＝Y(jié)ou've lost touch with real life. 你脫離了現(xiàn)實生活。
