I think我想； B. I don think so不不这么认为；C. I agree我同意；D. I dont agree我不同意。根据下文,but Alan doesnt think so.但是艾伦不这样认为,可判断答语为肯定回答I agree,故答案为C。 4. 【答案】B【解析】试题分析：考查名词词义辨析。句意: 那些拥有更多自信的人有更多的机会使自己成功。education教育, chance机会, pride自豪, excuse借口、理由。故选B。5. 【答案】A【解析】他的妈妈总是让他远离玩游戏。keep sb. away from doing sth. 让某人远离,from介词,后接动名词作宾语。6. 【答案】B【解析】句意：Tina没有去参加他的生日聚会,因为她没有被邀请。根据Tina didnt go可知,本句是一般过去时态；又因为主语是she与动词invite是被动关系；一般过去时态的被动语态的构成：was/were+动词的过去分词,结合句意“没有被邀请”,故答案选B。7. 【答案】B【解析】句意：如果他花太多时间玩电脑游戏会怎么样？此句是if引导的条件状语从句,if从句中的谓语动词spends是动词三单形式,时态为一般现在时,故主句要用一般将来时；spend some time on sth意思是“在某事上花费时间”,只有B答案符合题意,故答案为B。8.【答案】C【解析】句意：对青少年来说和老师顶嘴是不礼貌的。A. talk back顶嘴；B. talk to和某人交流；C. talk back to和某人顶嘴；D. talk with与某人交流。宾语their teachers的前面要用介词,结合句意可知,答案为C。9. 【答案】D【解析】句意：站在树下那个穿着白色T恤衫的女孩是谁？我的朋友。因为句子中有谓语is,因此空格处缺少非谓语动词,现在分词standing作后置定语,修饰the girl,故答案为D。10.【答案】A【解析】试题分析：句意：请停止吸烟,在医院不允许吸烟。stop doing sth,停止做某事,表示停止正在做的事情；sstop to do sth,停下来做某事,表示停止正在做的事情,做另一件事。当主语是动词的承受者时,用被动语态。结合句意,故选AII. 11. dont think; should be allowed 12. old enough 13. instead of talking 14. disagree with 15.should tell to do4
