A. | in need | B. | on duty | C. | at work | D. | in danger |
分析 --大多數(shù)野生動(dòng)物由于惡劣的生存條件而處在瀕危之中.
--所以我們必須采取措施拯救它們.
解答 答案:D.
首先明確選項(xiàng)中每個(gè)單詞或短語(yǔ)的意思,A:需要;B:值日;C:在工作;D:處于危險(xiǎn)中;根據(jù)題干結(jié)合推測(cè)設(shè)空處句子的句意是"大多數(shù)野生動(dòng)物由于惡劣的生存條件而處在瀕危之中.",由此判斷句子中缺少"處于危險(xiǎn)中"一詞,故答案為D.
點(diǎn)評(píng) 英語(yǔ)介詞的一個(gè)特點(diǎn)是一詞多義,并且介詞間語(yǔ)義交叉現(xiàn)象很多,習(xí)慣用法也很多,有時(shí)很難從詞義上區(qū)分開來.故學(xué)習(xí)中要注意不斷總結(jié),熟記一些介詞和動(dòng)詞的固定搭配用法及習(xí)慣用法,是完成此類問題的捷徑.

It's almost time for Science Night. I need a partner.Who should I ask? I have three friends who all want to help. How can I choose just one for the task? My best friend Jule is fun to be around. But she's as chatty as a bird. When she start to talk-just watch out! I can't get in a single word. Still,that might work for Science Night; She'd show our project to the crowd. Jule's voice would boom out like a drum. I wouldn't mind if she were extra loud! And then there's Dan,who's really shy But wise as an owl-he's so smart? He'd help with the thinking for the job. He wouldn't talk,but he'd do his part. | But what about Shel,who's good at art? He paints and draws and sculpts so well. Our project would look great no doubt! I'm sure I should be asking Shel. How can I choose just one from three? I need them all!I'm feeling sick. I'm as dizzy as a spinning top. When trying to choose.I just can't pick! But wait-why not ask them all to help? A group of four is better than one. I'd love to work with all my friends. In such a group,we'd have such fun! The work could be shared by four of us. Be me and Shel and Dan and Jule. We'd fit together like puzzle pieces. And take the grand prize in the school! |
