9、ercise early in life seems to have lifelong benefits for the brain, in rats at least”可知，早期鍛煉似乎對(duì)大腦終身有好處，至少對(duì)老鼠來(lái)說(shuō)是這樣的。故選D項(xiàng)。2C考查寫(xiě)作手法。根據(jù)第三段的“Wojtowiczs team divided 80 young male rats into two equal groups.Around four months later.they froze with fear”和第四段的“Two weeks later，the team tested the rats in thr
10、ee situations”可知，本文第三、四段描述了Wojtowicz的研究小組對(duì)老鼠進(jìn)行實(shí)驗(yàn)的過(guò)程。C項(xiàng)意為“通過(guò)描述過(guò)程”，故選C項(xiàng)。A項(xiàng)意為“通過(guò)分析原因”；B項(xiàng)意為“通過(guò)舉例子”；D項(xiàng)意為“通過(guò)展示不同點(diǎn)”。這三項(xiàng)均不符合第三、四段的發(fā)展脈絡(luò)。3A考查代詞指代。根據(jù)第二段的“but it shows that physical activity at a young age is very important”及“In humans，it may delay the appearance of Alzheimers disease(阿爾茨海默病)”可知，身體活動(dòng)很重要，對(duì)人類(lèi)來(lái)說(shuō)，它
11、可能會(huì)推遲阿爾茨海默病的出現(xiàn)。因此“it”在文中指的是“physical activity”， A項(xiàng)與其同義，故選A項(xiàng)。4B考查觀點(diǎn)態(tài)度。通讀全文可知，作者介紹了對(duì)老鼠進(jìn)行實(shí)驗(yàn)的過(guò)程及其結(jié)果，并引用數(shù)據(jù)進(jìn)行說(shuō)明，由此可知作者對(duì)動(dòng)物研究的態(tài)度是很客觀的。B項(xiàng)意為“客觀的”，故選B項(xiàng)。*語(yǔ)法填空。They survive in some of the coldest environments in the worldbut even penguins appreciate a warm woolly jumper (套頭毛衣) once in a while.The mini knitted ga

16、拯救了數(shù)百只企鵝，能防止它們接觸到石油中的微量元素，甚至誤食有毒的污染物。1in 考查介詞。這里是“be caught in”的固定搭配，意思為“被困于中”。文中是過(guò)去分詞短語(yǔ)作定語(yǔ)修飾flightless birds。2poisonous 考查詞性轉(zhuǎn)換。poisonous作為形容詞修飾其后面的名詞。3which 考查定語(yǔ)從句的引導(dǎo)詞?？仗幰龑?dǎo)非限制性定語(yǔ)從句，指代先行詞the Penguin Foundation，并在從句中作主語(yǔ)，故用which。4has created 考查動(dòng)詞的時(shí)態(tài)。根據(jù)時(shí)間狀語(yǔ)“over the years”可知這里用現(xiàn)在完成時(shí)，句子的主語(yǔ)是一個(gè)名為Knits for
17、 Nature的項(xiàng)目，故謂語(yǔ)動(dòng)詞要用第三人稱(chēng)單數(shù)。5hidden 考查非謂語(yǔ)動(dòng)詞。creativity是名詞，其前要用形容詞修飾，動(dòng)詞hide與creativity之間為邏輯上的動(dòng)賓關(guān)系，故用過(guò)去分詞。此處為過(guò)去分詞轉(zhuǎn)化而來(lái)的形容詞作定語(yǔ)。6because 考查連詞?！皌heyre so cute and small and they waddle up the beach and theyre so strong”是“People love to know that theyre helping the penguins”的原因，故用because引導(dǎo)原因狀語(yǔ)從句。7a 考查冠詞。此處表示泛
18、指，且pretty的讀音是以輔音音素開(kāi)頭的，故用a。a pretty tough sort of environment表示的是“一種相當(dāng)惡劣的環(huán)境”。8smallest 考查形容詞的最高級(jí)。根據(jù)上下文語(yǔ)境和空前的the可知這里應(yīng)該用最高級(jí)。9that 考查賓語(yǔ)從句的連接詞。分析句子成分可知，空處引導(dǎo)賓語(yǔ)從句作estimates的賓語(yǔ)，賓語(yǔ)從句中句意和成分完整，故用that。10those考查代詞。those指代前面所說(shuō)的penguin jumpers。*完形填空。It was a day in late June, gray and depressing, with clouds hangi
