4. In all，Columbus made three more voyages during the next ________(十年).
答案：decade
5. He returned from Paris and found his office was under someone else’s ________(占領).

Ⅱ. 易錯模塊
1. (2008年高考江蘇卷)—I’m sure Andreill win the first prize in the final.
—I think so. He ________ for it for months.
A. is preparing B. was preparing
C. had been preparing D. has been preparing
解析：選D。句意：——我相信Andrew會贏得最后的決賽�！乙策@樣想，他已經(jīng)準備了好幾個月了。從對話語境可知prepare這一動作從過去一直持續(xù)到說話的現(xiàn)在，故用have been doing結構。
2. —I have got a headache.
—No wonder. You ________ in front of that computer too long.
A. work B. are working
C. have been working D. worked
解析：選C。句意：——我頭疼�！蛔銥槠�。你坐在電腦前工作了很長時間。由語境可以看出，work開始于過去持續(xù)到現(xiàn)在，故用現(xiàn)在完成時，而進行體表示感情色彩，即說話者在本句中表示“抱怨”的語氣，故用現(xiàn)在完成進行時。
3. They ________ on the program for almost one week before I joined them，and noe ________ on it as no good results have come out so far.
A. had been working；are still working
B. had worked；were still working
C. have been working；have worked
D. have worked；are still working
解析：選A。此題考查的是時態(tài)問題。從before引導的從句中的過去時態(tài)可知主句的時態(tài)應為過去完成時，故排除C、D。從意思上可以看出他們一直工作了一周，強調(diào)動作的持續(xù)，同時now也提示出后面應用現(xiàn)在進行時。
Ⅲ. 情景交際
1. (2010年成都市摸底測試)—Don’t forget to return the book in two weeks.
— ________. Don’t worry about it.
A. Yes，I won’t B. No，I won’t
C. Sorry，I wouldn’t D. I don’t think so
解析：選B�？疾樘厥饩涫�。上一句是否定祈使句，再結合答語的后一句可知說話人不會忘記，所以選擇B項，意思是“是的，我不會忘記”。
2. (2010年江西撫州地區(qū)聯(lián)考)—I’m afraid that I can’t finish the task as soon as planned.
— ________.
A. Don’t be afraid B. Don’t mention it
C. I suppose so D. Take your time
解析：選D�？疾榻浑H用語。從語意看，I’m afraid委婉地提出了自己的擔心，因此本題選D，表示勸對方別著急，慢慢。B用回答別人的感謝，C表示“我想是這樣的”，不符合語意。
3. (2010年河北辛集中學期中測試)—Excuse me，can you spare me a few minutes?
— ________？
A. What’s on B. What is it
C. What’s up D. What’s more
解析：選C�？疾榻浑H用語。對方詢問是否能抽時間和他談幾句，因此選C項回答，“有什么事？”
Ⅳ. 語法專練
本單元語法——v. ing形式作主語和賓語
1. ________the meeting himself gave them a great deal of encouragement.
A. The president will attend
B. The president to attend
C. The president attended
D. The president’s attending
解析：選D。本題考查動名詞的復合結構作主語的用法。選項A時態(tài)不對；不定式作定語一般也用表示將要發(fā)生的動作；主語從句中的that不能省略。
2. While shopping，people sometimes can’t help ________into buying something they don’t really need.
A. to persuade B. persuading
C. being persuaded D. be persuaded
解析：選C。can’t help表“禁不住”時，后跟動名詞形式，句意：逛商店時，人們有時忍不住被勸說著買一些他們并不需要的東西。
3. ________these suggestions will help you become more cooperative and achieve more.
A. Followed B. Following
C. To follow D. Being followed
解析：選B�？疾榉侵^語動詞。句意：遵循這些建議將有助于你更富有合作精神并取得更大的成就。following these suggestions是動名詞短語作主語。follow與you之間是主謂關系，排除A、D；不定式作主語通常用表示偶然性或具體的動作，因此C項不恰當。
4. ________to sunlight for too much time will do harm to your skin.
A. exposed B. Having exposed
C. Being exposed D. After being exposed
解析：選C�？疾閯用~作主語。因為expose的邏輯主語是skin，兩者是被動關系，所以用被動形式。
5. It’s fun ________in a river or a lake with some friends in summer.
A. to be swimming B. swimming
C. swam D. swim
解析：選B。考查it’s fun doing. . . 的固定句型。此處it為形式主語，真正的主語是動名詞短語。不定式也能作主語，但它往往表示將某個具體的動作，而動名詞作主語往往表示經(jīng)常性、習慣性的動作
