life. a new report on 3,375 students aged from 10 to 18 in seven chinese cities found that 38 percent of them believe they use the internet often.while most of them get useful information and use the internet to help in their studies, some are not using it in a good way. many are playing online games too much. a few even visit websites(网址) they should not look at. hong ying, a teacher from beijing yinghua middle school warns(警告) that bad things can happen if young people spend too much time on the internet. she had a student who used to be good at school. but then he started visiting unhealthy websites. he went mad, cheated(欺骗) a girl and was taken away by the police.in order to help young people use the internet in a good way, a textbook on good internet behavior(行为) has started to be used in some shanghai middle schools this term. the book uses real examples to teach students about good ways of using the internet. the book gives useful advice such as to read news or to find helpful information to study. teachers and parents all think the book is a very good idea.hong said the book will be a guide for teens to use the internet. she believes it will keep students away from bad sites.“many students are using the internet without guidance(指导) from their parents,”she said, “the book will teach students how to be a good person in the online world.”根据短文内容，选择最佳答案。( )26.how many

one object but several ones.” the captain said, “we saw one large and six smaller objects. i sent out a radio report about them and i got some information that the other planes were coming out to meet

18. writer 19. music 20. chat第二部分 基础知识运用. 1.c考查表示同意功能的交际用语。thank you. 是用来答谢对方的语言, youre welcome.是答谢的应答语,id love to. 是回答邀请的。sure. 在这里的意思为“当然”,表示同意。故选c。2.d考查动副词组与代词的搭配。look . up in the dictionary 意为“查字典”,look是动词,up是副词,代词应在look与up之间,由于words是可数名词复数,故应用them。故选d。3.d考查连词。主句和从句都是过去进行时,要用while。题干的意思为: “当我父亲在看报纸时,我正在做作业。” 故选d。4.b考查疑问词+不定式。由于空格后有it,排除a,根据题意,选b。5.a考查词义辨析。句子是spend . doing sth. 结构, 意为 “花做某事”, 此句中volunteering前省略了in,只有a项符合题意。 6.c考查形容词比较级。句中有than提示用比较级,排除a。根据上下句的意思,“现在我们家乡的空气比以前,所以我们一定要做些事来阻止它。” 推测出空气应比以前更糟糕,故选c。7.c考查介词。come in “进来”, come from “来自”, come over “过来”, toward “朝” 根据题意,这艘船正驶向他们。故选c。8.a考查冠词。根据题意，判定是泛指,排除c, ufo这个单词不是以元音音素开头,故选a。9.d考查介词+动名词。只有d项是动名词形式,故选d。10.c考查固定搭配take the place of sb/sth. “代替，替换某人/某物”。. 11.c 12.e 13.a 14.b 15.d. 16.b考查词义区别。much 在这里作代词,充当do的宾语。17.c考查上下文推测。许多年前的计算机既大又贵。and前是big,故其后也应用原级。18.d考查词组固定搭配。由于主语是人,故用be interested in对感兴趣。19.b考查上下文推测。上文说过去的计算机大且贵, 推测出现在的计算机更小更便宜。故选b。20.a考查词义理解。do difficult work “做困难的工作”。21.d考查词义理解。根据下文表明计算机逐渐变得重要了。故选d。22.b考查介词。in+时间段
