答案

1.—You should have thanked her before you left.
—I meant ____,but when I was leaving I couldn’t find her anywhere.
A.to do B.to C.doing D.doing it
答：B
译：你离开之前应该向她表示感谢的.
我是想这么做的,可要离开的时候,我到处找不着她.
析：mean to do sth.表示“心里想着要做某事”,而mean doing sth.表示“意味着...”所以排除CD
为避免得复,不定式可以省略到to为止.I meant to =I meant to do so.
A.do缺少宾语,反而错了.
2.Though the foreign students came to our school only a month ago,they ____themselves to the conditions here now.
A.have adjusted B.are adjusting C.had adjusted D.adjusted
答：A
译：虽然来我校才一个月,这些外国的学生现在已经适应这里的环境了.
析：主句中的时间状语为now,用现在时态,排除CD.
从句意看,不是现在正在调整适应,而是已经适应了,这才与although句相配.
3.Beneath our feet____that our life depends on for food and clothing.
A.does the earth lie B.the earth lies C.lay the earth D.lies the earth
答：D
译：我们的脚下是我们的衣食所父母--地球.
析：为避免头重脚轻,本句用了全倒装,将作表语用的介词短语提到句首,带定语从句（that-从句）的主语the earth放在谓语动词（lies,是系动词,可用is替换）之后.
