英語題目有答案,求解析原因

B77. I need some more food. Would you like to give me two more apples?

選擇:B. some more; two more

解析:修飾名詞定語的排序為“限定詞(包括不定代詞) + 數詞 + 形容詞 + 名詞”,因此應該是“限定詞some + 形容詞more + 名詞food”和“數詞 two + 形容詞more + 名詞apples”

A78. --- Do you spend a lot of time on computer? --- No, but I spend much time in doing my homework.

選擇:A. on; in

解析:spend time 後面如果是具體事物,應該用介詞on,即spend … on sth.,如果是表示做某事(動名詞),應該用介詞in或者省略介詞,即 spend … (in) doing sth.

D79. --- Would you like________ the environment? --- I don’t know. What can I do?

選擇:D. to help save

解析:

1、would like 後面只能跟不定式作賓語,表示願意做某事,因此應該用 to help

2、help 後面也需要不定式作賓語,也可以省略 to,即 help do sth.。本題選項中的help save 就是省略用法。

C80.____ is wrong to copy other students’ homework.

選擇:C. It

解析:句中的真實主語是後置的不定式短語,it是形式主語,即it is wrong to do sth. (做某事是不對的)

B81. It is bad for your eyes playing computer games too much.

選擇:本命題有錯,沒有別的選擇,只能用to play

解析:本句與上句C80屬於同壹種用法,只不過是不定式多了邏輯主語for your eyes,即 it is … for… to do sth.

特別說明:當 it is後的表語如果是表示有益或無益的 good, bad, helpful, useless, useful等詞匯,只能用動名詞作真實主語,因此此題正確的選擇是選項中沒有的playing。

C82. —______ go to the theatre together with me? —Good idea.

選擇:D. Why not

解析:本句表示建議,這種語氣可以用How about、What about和Why not多種方法表達,但是前者的 about是介詞,後面只能跟動名詞短語going to the theatre。Why not go to the theatre是Why don’t we go to the theatre的省略(省略了助動詞 do和主語 we)。

B83. Miss Yang does a helpful job in the school library, many student are grateful ___ her.

選擇:B. to

解析:“(因某事)感謝某人”的表達法是be grateful to sb. (for sth.)

A84. Although he was a child, he tried to find ways to help people enjoy life more.

選擇:A. to help ; enjoy

解析:第壹空用不定式 to help是ways 的定語,即“幫助人的方式”;第二空的道理同D79,help 只能用不定式作賓語。

D85. --- Can I use your mobile phone? --- Sorry, my mobile phone _____ .

選擇:D. needs repairing

解析:“人需要做某事”用need to do,“事物需要被做”用need doing 或者need to be done;my mobile phone是單數第三人稱,因此用needs repairing。

C86. - ___ do I need to take ? - It’s helpful for you to take a map and a mobile phone if you get __ .

選擇:C. What else, lost

解析:else只能放在疑問代詞或不定代詞之後。get 後應該是作表語的過去分詞lost,相當於被動語態be lost。
