分析 文章大意:本文介紹了有的哺乳動(dòng)作生下來(lái)幾分鐘就可以走路,而人類的新生兒生下來(lái)卻不能,人一生下來(lái),甚至不能微笑或坐立,也抬不起頭,在人類出生的第一年,這些動(dòng)作是一步一步逐漸學(xué)會(huì)的,對(duì)人類來(lái)說(shuō),成長(zhǎng)要花很多努力.

解答 16.B 考查名詞辨析.A表示食物; B表示危險(xiǎn);C表示浪費(fèi);D表示和平.由They have to be able to run away可推知逃跑是在遇到危險(xiǎn)時(shí)的動(dòng)作,選B,表示如果附近有危險(xiǎn)時(shí).
17.D 考查形容詞辨析.A表示粗心 的;B表示無(wú)害的;C表示無(wú)望的;D表示無(wú)能的,無(wú)用的.由They need the care of adults to live可知此處表示一個(gè)人類的寶寶生下來(lái)卻是無(wú)能的(此處的無(wú)能指的是不能自己走和跑),選D.
18.C 考查介詞辨析.A表示…的;B表示對(duì)于,為了;C表示沒(méi)有;D表示通過(guò).由But human babies are born helpless可知此處表示沒(méi)有大人的幫助,他們甚至不能抬起頭,選C.
19.A 考查副詞辨析.A表示甚至;B表示從不;C表示曾經(jīng);D表示仍然.結(jié)合語(yǔ)境可知此處表示他們學(xué)習(xí)翻身,支撐起自己的頭,甚至是在支撐下坐立起來(lái),選A.
20.D 考查名詞辨析.A表示腿;B表示頭;C表示眼睛;D表示手.由At around six months old many babies can(21)an object from one hand to another可知此處表示嬰兒也得學(xué)習(xí)使用他們的手,選D.
21.B 考查動(dòng)詞辨析.A表示保持;B表示移動(dòng);C表示抓;D表示使.由It takes months for them to learn to reach for objects可推測(cè)此處表示大約六個(gè)月時(shí),許多嬰兒可以將一個(gè)物體從一個(gè)手移到另一個(gè)手,選B.
22.B 考查表語(yǔ)從句.分析句子可知空格處引導(dǎo)表語(yǔ)從句作is的表語(yǔ),babbling指的是人類的嬰兒學(xué)習(xí)說(shuō)話的方式,要用how來(lái)引導(dǎo),選B.
23.A 考查連詞辨析.A表示之前;B表示自從;C表示之后;D表示當(dāng)…時(shí).由Babies all seem to make similar sounds by babbling.They try to imitate (模仿) the sounds they hear from adults可推測(cè)此處表示在嬰兒能夠真正地說(shuō)出話前要花上九個(gè)月的時(shí)間,選A.
24.C 考查動(dòng)詞辨析.A表示看; B表示展示;C表示跑;D表示坐.由Somewhere around a baby's first birthday he or she may stand or walk with help可推測(cè)此處表示的是不久后這個(gè)嬰兒會(huì)自己跑了,因?yàn)榇司淝懊枋龅膭?dòng)作是站立和行走,之后的動(dòng)作應(yīng)該是跑,所以選C.
25.D 考查動(dòng)詞辨析.A表示說(shuō);B表示微笑;C表示哭;D表示學(xué)習(xí).由上文提到的They learn to roll over,support their heads…和Babies also have to learn to use their hands可知此處表示的是嬰兒時(shí)期的第一年是成長(zhǎng)和學(xué)習(xí)的一年,選D.
