One Good Reason to Let Smallpox Live

It’s now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980，when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it — one in the US and one in Russia.

答案與題解：

1.A inreality:“實際上,事實上”。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符合這一原則。

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,因此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,其他的選項都不可以。

6.B整個句子說的是美俄“官方”保存的最后的活病毒儲備由于不能帶來明顯的好處而引起大家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。可以看出,上半部分所描寫的model應該是實際上存在的。此處應該用found。它是外延動詞,表示model是存在的。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。因此是不合適的。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“為某事的發生創造了條件”。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是不正確的,后面必須有地點狀語。如:You can put the virus in a bottle, destroy the virus 和eradicate the 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是固定的說法,意思是“萬一”。整個句子說的是:因此,又有了一個保存病毒的理由——萬一這種病卷土重來。

11.C這幾個選項意思差不多,但只有deal可跟with搭配。

12.D從緊隨其后的句子來看,用simple是正確的。difficult, hard和safe都跟后面的句子在意思上不連貫。

13.A under the auspices是固定的說法,意思是“贊同”、“支持”。

14.B It doesn’t mean that...是一種固定的表達法。也可以說：It doesn’t mean to say that...

15.C本句是個條件句。從句中動詞一般用現在時表示“未來”。這就排除了will be和would be。virus是單數,因此D也不正確。
