7、。這是固定的說法。2. B 此處應填入一個非事實性動詞。 imagine 是非事實性動詞。 know,realize 和 be aware 都是事實性動詞 , 所以不合適。屬于非事實 性動詞還有 believe,think 等。3. C let 跟動詞原形 ,go 符合這個原則。4. D vials 是復數,much不合適。另外，本句和上文都沒有比較的 意思，所以more和most也都不合適。5. A 上一句句末的標點符號表明本句是一個獨立的句子。只有and可用于一個獨立的句子 , 其他的選項都不能夠。6. B 整個句子說的是美俄“官方”保存的最后的活病毒儲備因為不 能帶來明顯的好處而引起大家

8、對這兩個國家的不信任。 no obvious gain 是名詞短語。 for 可跟名詞短語 , 表示原因。 because 不跟名詞短 語。 since 可跟名詞短語 , 但跟表示時間的名詞短語。 of 可跟名詞短語 , 但常表示“所屬”關系。7. C opening the way for tests on new treatments and vaccines ：為試驗新的治療方法和新的疫苗開辟了道路”。這是句子 的下半部分。能夠看出 , 上半部分所描寫的 model 應該是實際上存有的。 此處應該用 found. 它是外延動詞 , 表示 model 是存有的。 looked for和 sought 是內涵動詞。它們引起的名詞短語并不一定有外延。所以是 不合適的。 talked about 是“談論”的意思。用在這里 , 也是不妥的。8. D open the way 是一種固定的說法 , 意思是“為某事的發(fā)生創(chuàng)造 了條件”。類似的說法還有： clear the way,prepare the way 等。9. A keep the vims是“保存病毒”的意思。 put the virus 是不準確的 , 后面必須有地點狀語。如： You can put the virus in a bottle,destroy the virus 和 eradicate the
