1. Why were you not at the concert last night?
I ______ a close game between Seattle Sonnies and Miami Bucks.
A. watched B. was watching

选B。本题考查时态。过去进行时表示过去某段时间正在进行的动作。
2. Some college students are see doing______work they ca find to support themselves.
A. that B. which
C. whatever D. no matter what
选C。此题考查whatever=anything that，相当于一个定语从句。选项A需在that 前加anything，其他选项均不符合题意。
3. I cant find my watch. I must have______it in the hotel.
A. lost B. missed C. left D. forgotten
选C。D较有一定的干扰性。按照汉语习惯我一定是把它忘在宾馆了，但forget 意思是忘记，表示没有记住，因此应用表示遗留在的leave。选项A、B有一定干扰性，lose和miss表示丢失；不见了，因此不合题意。
4. It is thought that one billion people I the world,
is half the words workers, earn their living by farming.
A. if B. that C. which D. what
选B。句中half the worlds workers是对one billion people in the world 的补充说明，that is是that is to say的省略说法，是插入语，that 并不是引导非限制性定语从句的，如果在 that is后加个逗号则更清楚，应选B。
5. The editors job is to keep the newspaper ______and ______to the readers.
A. balanced; interested
B. balancing; interesting
C. balanced; interesting
D. balancing; interested
选C。balanced 在此是过去分作宾补，意为平衡的；interesting 作形容词修饰物，interested 修饰人。
6. The river, ______the bank are covered with trees, is very long.
A. whose B. which
C. of which D. which of
选C。名词或代词+关系代词whom / which可以引导非限定性定语从句。表示部分与整体的关系，作用相当于whose+名词，of which the bank =the bank of which = whose bank, 因此答案为C。
7. Your name again, please? ______ .
Its Bell Green.
A. I didnt quite catch you
B. I couldnt quite catch you
C. I dont hear you
D. Its your name
选A。让对方重复其姓名，是因为没有听清(表示事实)。catch此处意为听清。B项是干扰项，说话人要表述的是刚才没有听清，而不是不能听清。
