() 1.When he was ______ university student, he wanted to be ______ NBA player.
A.a; a
B.an; an
C.a; an
D.an; a

C

首先分析第一个空，"university"虽然以元音字母u开头，但发音是/juː/，为辅音音素开头，故用不定冠词a。接着看第二个空，"NBA"以元音音素/e/开头，所以用不定冠词an。综合两个空，答案应为C选项。

() 2.Sandy feels unhappy because nobody seems to ______ her progress.
A.look
B.watch
C.notice
D.read

C

根据句意“桑迪感到不开心，因为似乎没人______她的进步”，需要一个表示“注意到”的动词。A.look强调看的动作，为不及物动词，常与at连用；B.watch侧重观看动态的事物；C.notice指注意到、察觉到，符合语境；D.read意为阅读。此处表示注意到进步，用notice，选C。

() 3.My brother graduated ______ high school ______ 2002.
A.from; in
B.in; from
C.from; at
D.at; in

A

graduate from 为固定搭配，意为“从……毕业”；年份前用介词 in。因此第一空填 from，第二空填 in。

() 4.Anderson, the writer of The Little Match Girl, ______ single all his life.
A.reminded
B.recommended
C.remained
D.remembered

C

分析句子结构，此处需谓语动词，根据"single all his life"（一生单身）可知表达“保持单身”状态。A.reminded（提醒）；B.recommended（推荐）；C.remained（保持，仍然是）；D.remembered（记得）。"remained single"为固定搭配，意为“保持单身”，符合语境。

() 5.High-speed trains are seen as one of the new Four Great ______ of China.
A.Achievements
B.Agreements
C.Environments
D.Instruments

A

"新四大发明"指中国的重大成就，"Achievements"意为"成就"，符合语境；"Agreements"（协议）、"Environments"（环境）、"Instruments"（工具）均不符合。

() 6.______ he isn't interested in Chemistry, ______ he gets high grades every time.
A.Although; but
B.Because; so
C.Although; /
D.Because; /

C

在英语中，although（虽然）和but（但是）不能同时使用，because（因为）和so（所以）也不能同时使用，故排除A、B选项。根据句意“他对化学不感兴趣，每次都能得高分”，前半句表让步，应用although，后半句无需连词。

三、阅读填空
