4. D 空格所在的句子說“他們已經(jīng)...一個(gè)藥丸， 該藥丸把現(xiàn)在市場上在出售的三種藥合成在一起”，上文提到“有兩家公司已經(jīng)在進(jìn)行把治療艾滋病的多種藥合成一種藥的工作” ， 因此空格處出現(xiàn)“開發(fā)，研發(fā)”(D項(xiàng))恰當(dāng)。

5. C 這幾個(gè)介詞中，只有under可以與name組合成短語under the name of (“以…名，名為…”)，其它選項(xiàng)在這里均不合適。

6. A) one(一， 一個(gè)，任何人) B) ones
C) other(其他的，其他人) D) others(其他人， some...others...一些...一些...)
Gilead combined the ____6____, Emtriva and Viread, into a single pill in two thousand four.
6. D 上面提到兩家公司已經(jīng)開發(fā)出將多種藥合成為單片的新藥，Myers公司已合成了一種，Gilead公司則于2004年將其它兩種Emtriva和Viread合成為單片，這里既然列出了這兩種藥的名稱，所以就必須用“others”。

8. A 被選項(xiàng)B和D互為近義詞， 因此彼此排除掉。剩下的選項(xiàng)都可引導(dǎo)狀語從句， 因此關(guān)注空格所在的從句與主句之間意義關(guān)系。 句子主句說“它也涉及到競爭方面的問題”， 從句說“藥品由不同的廠家生產(chǎn)”， 顯然從句與主句之間是“條件”與“結(jié)果”之間的關(guān)系，因此if(如果)合適。
考點(diǎn)：狀語從句
9. A) that B) which
C) what(什么， ...的) D) whatever(無論什么，無論哪一種的)

9. C the result of后面出現(xiàn)的應(yīng)該是一個(gè)賓語從句，且空白處的連接詞應(yīng)該充當(dāng)賓語從句的主語，首先我們可以排除that(that引導(dǎo)名詞性從句時(shí)，that在從句中不充當(dāng)任何語法成分，僅僅起一個(gè)連接從句的作用 )和which(which引導(dǎo)名詞性從句時(shí)， which后常常會(huì)帶有一個(gè)單數(shù)的名詞)，因此答案只能來自C和D。這兩個(gè)選項(xiàng)的差別是what是特指，而whatever是泛指。空格所在的句子說“這種新的每天服一次的藥丸被描述成在治療HIV病毒的過程中所達(dá)成的第一個(gè)合資協(xié)議的產(chǎn)物”，這是特指，不是泛指， 因此what是答案。
