7、這是固定的說(shuō)法。2. B 此處應(yīng)填入一個(gè)非事實(shí)性動(dòng)詞。 imagine 是非事實(shí)性動(dòng)詞。 know,realize 和 be aware 都是事實(shí)性動(dòng)詞 , 所以不合適。屬于非事實(shí) 性動(dòng)詞還有 believe,think 等。3. C let跟動(dòng)詞原形，go符合這個(gè)原則4. D vials 是復(fù)數(shù),much不合適。另外，本句和上文都沒(méi)有比較的 意思，所以more和most也都不合適。5. A 上一句句末的標(biāo)點(diǎn)符號(hào)表明本句是一個(gè)獨(dú)立的句子。只有and可用于一個(gè)獨(dú)立的句子 ,其他的選項(xiàng)都不能夠。6. B 整個(gè)句子說(shuō)的是美俄“官方”保存的最后的活病毒儲(chǔ)備因?yàn)椴?能帶來(lái)明顯的好處而引起大家對(duì)這兩個(gè)國(guó)家

8、的不信任。 no obvious gain 是名詞短語(yǔ)。 for 可跟名詞短語(yǔ) , 表示原因。 because 不跟名詞短 語(yǔ)。 since 可跟名詞短語(yǔ) , 但跟表示時(shí)間的名詞短語(yǔ)。 of 可跟名詞短語(yǔ) , 但常表示“所屬”關(guān)系。7. C opening the way for tests on new treatments and vaccines ：為試驗(yàn)新的治療方法和新的疫苗開(kāi)辟了道路”。這是句子 的下半部分。能夠看出 , 上半部分所描寫(xiě)的 model 應(yīng)該是實(shí)際上存有的。 此處應(yīng)該用 found. 它是外延動(dòng)詞 , 表示 model 是存有的。 looked for和 sought

9、是內(nèi)涵動(dòng)詞。它們引起的名詞短語(yǔ)并不一定有外延。所以是 不合適的。 talked about 是“談?wù)摗钡囊馑肌Ｓ迷谶@里 , 也是不妥的。8. D open the way 是一種固定的說(shuō)法 , 意思是“為某事的發(fā)生創(chuàng)造 了條件”。類(lèi)似的說(shuō)法還有： clear the way,prepare the way 等。9. A keep the vims 是“保存病毒”的意思。 put the virus 是不 準(zhǔn)確的 , 后面必須有地點(diǎn)狀語(yǔ)。如： You can put the virus in a bottle,destroy the virus 和 eradicate the virus 都是“消滅病毒” 的意思 , 跟后半句話在意思上是矛盾的。10. B in case 是固定的說(shuō)法 , 意思是“萬(wàn)一”。整
