答案及解析
1. A.分析：被選項是介詞，注意搭配結構。in reality“實際上，事實上”是固定搭配使用的說法。
2. B. 分析：借助被選項的特點： know = be aware，排除A和D，再借助搭配結構(..是天真的)判斷B(想象)是答案。
3. C. 分析：1et跟原形動詞，go符合這一原則。
4. D.分析：根據搭配結構--..小瓶，判斷D最合適(而且該句和前句中都沒有出現比較的含義)
5. A.分析：該句結構是“句子 短語結構”，因此空格5處的連詞必須能引導一個獨立的句子，這樣判斷只有A合適(其他選項都只能引導從句結構)
6. B.分析：借助被選項的特點B和C相關，用法不同，重點注意，再借助空格后是名詞性結構這個特點判斷B合適。
7.C.分析：借助被選項的特點A和C有關系：前者是“尋找”，后者是“找到”，重點注意。借助該句子主干結構大意：“現在美國研究者已經..，開啟了...”，這樣判斷C(找到)合適。
8.D.分析：借助被選項的特點：method 的習慣搭配介詞是of，因此排除A; B和C都是具體指代“街道”，而 way可以抽象和具體的指代“道路”，判斷D合適。
9. A.分析：該句的結構與標題的結構一致，因此借助標題內容直接判斷A(保留/保存)是答案。
10.B.分析：借助搭配結構“in..判斷A，B和D是答案”，再根據空格后是一個句子的特點判斷B(in case conj.萬一)是答案。
11. C. 分析：借助搭配“.. with”直接判斷C是答案。
12. D.分析：借助下文句子是在教人們怎樣做(祈使句結構)，因此判斷D是答案。
13. A. 分析：被選項是介詞，所以注意搭配結構：keep...in a .. laboratory; .. international auspices(贊助)，根據介詞的基本含義和用法判斷A(under prep.在...之下， 在...領導下)是答案。
14. B. 分析：因為空格是作謂語，而句子主語是“非人”，所以A，C 和D都不行(這些詞的主語往往都是是“人”)
15. C.分析：首先借助后面主句中的代詞it判斷前面的the virus應該是單數，而且狀語從句結構中只能用一般時態來表示將來，所以判斷C是答案。
