? ? ? ?1.Living in the desert involves a lot of problems, ______ water shortage is the worst.
A.which
B.of which
C.of whose
D.for what
【翻譯】在沙漠中生活要牽涉很多問題,其中缺水是最嚴(yán)重的問題。?
[考點(diǎn)]??定語從句?
【精析】B 分析句子結(jié)構(gòu)可知,逗號(hào)后面為一個(gè)非限制性定語從句,修飾problems,且water shortage和problems之間為所屬關(guān)系,所以應(yīng)用of which來引導(dǎo)。故選B。
2. If they had worked harder, they____ the project ahead of time.
A.will finish
B.would have finished
C.have finished
D.had finished
【翻譯】?如果他們過去更加努力一點(diǎn)兒,他們就會(huì)提前完成這個(gè)項(xiàng)目了。
[考點(diǎn)]虛擬語氣
【精析】B 本句含有If引導(dǎo)的非真實(shí)條件句,根據(jù)從句中的謂語動(dòng)詞had worked可知,本句是對(duì)過去發(fā)生事情的假設(shè),所以主句謂語動(dòng)詞應(yīng)用“should/would/could/might have+過去分詞”的形式。故選B。
3. Generally speaking, prices of daily goods ________ through the Internet are lower than store prices.
A.to buy
B.are bought
C.buying
D.bought
【翻譯】一般來說,從網(wǎng)上購(gòu)買的日用品的價(jià)格要低于商店的價(jià)格。
?[考點(diǎn)]非謂語動(dòng)詞
【精析】D 分析句子結(jié)構(gòu)可知,空處應(yīng)用非謂語動(dòng)詞。根據(jù)句意可知,goods和buy之間是邏輯上的動(dòng)賓關(guān)系,所以應(yīng)用過去分詞表被動(dòng),作后置定語修飾daily goods。不定式作后置定語常含有將來的意義,不符合題意,所以排除選項(xiàng)A;B項(xiàng)是一般現(xiàn)在時(shí)的被動(dòng)語態(tài),不符合語法結(jié)構(gòu);C項(xiàng)是現(xiàn)在分詞,作后置定語時(shí)常表示主動(dòng)或正在進(jìn)行,因此可排除。故選D。
4. 62 percent of the people surveyed said they always avoided _______ their smart phones during meals.
A.use
B.using
C.to use
D.used
【翻譯】62%的被調(diào)查者表示,他們總是避免在用餐時(shí)使用智能手機(jī)。
[考點(diǎn)]????非謂語動(dòng)詞
【精析】B avoid doing sth.為固定用法,意為“避免做某事”,其中動(dòng)名詞作賓語。故選B。
5.On no account____ ever leave the baby at home alone.
A.should you
B.you should
C.did you
D.you can
【翻譯】你決不應(yīng)該把嬰兒一個(gè)人留在家里。????
[考點(diǎn)]倒裝句
【精析】A on no account意為“決不”,位于句首時(shí)句子應(yīng)部分倒裝,即將謂語中的助動(dòng)詞、情態(tài)動(dòng)詞或be動(dòng)詞提至主語之前,所以排除B、D兩項(xiàng)。根據(jù)句意可知,這里敘述的是一般情況,不用一般過去時(shí),所以排除C項(xiàng)。故選A。
