25、gallery10.affect.1.Cdo harm to sb.为固定搭配，意为“伤害某人”，排除A、B；hurt可指对心灵或肉体的“伤害”；injure强调意外事故中的“伤害”，由此可知第二空应为hurt。2A回答“不，你坐着，我去”表明一种意愿的行动。B项意为：“按约定或责任应该”；C项为“即将要去”；D项为动作即刻发生；而A项侧重表明说话者的意志。3B句意：尽管电话铃响了，但她还在继续看电视，好像没有事情发生一样。even if 相当于even though“即使”；as if“仿佛，好像”；so that“以便，以至于”。由句意可知，选B。4C句意：电视给我们提供了许多娱乐。ent
26、ertainment“娱乐”，符合语境。5C句意：他从不收拾桌子，所以桌子上总是一堆杂乱的书报。confusion困惑；disorder混乱，一般指人的行为或身体机能的紊乱；chaos混乱；pile堆，根据句意可知是指没有很好地摆放而混乱，故选C。6Chave an effect on对有影响，make up ones mind ot do sth.表示“下决心做某事”，故选C。7B句意：他使自己进入了一种很可能失去对飞机控制的危险处境中。be likely to do sth.可能做某事，是固定表达法。8A句意：一位妇女遭到一伙年轻人的袭击和抢劫。attack意为“袭击，攻击”，此处应用被动
27、语态，故选A。9A句意：他坐在教室里，眼睛盯着黑板。考查“with宾语宾补”结构，eye与focus是动宾关系，所以选focused。10B由句意可知此处真正的主语为“that her hair was turning gray”，故用it作形式主语。11A句意：他想有一天成为一个伟大的画家。他的理想迟早会实现的。come true“实现”，是个不及物动词短语，符合语境。realize“实现”，是及物动词；come out“出版”；publish“出版”。12A句意：我们应该帮助那些遭受水灾的人。根据句意可知A项正确。13B句意：在暴风雨中被吹倒的树已经从路上移走了。过去分词短语作后置定语表示
28、被动，故选B。14B句意：他并没有告诉我们他真正的想法。由句意可知，此处需要用副词，故选B项。15Bcost的主语为物；devote sth.to sth.把用于，但该动词形式在此题中不符合要求；spend后跟(in)doing sth.或on sth.；contribute.to把奉献给，符合要求。.1.C词义猜测题。该段最后一句话说邮箱中到处都是人们根本不需要的广告，由此可以推断出广告商向人们的邮箱中发送一些无用的信息。2A细节理解题。文中列举了网络给人们带来的不利之处，而所有这些都是由于网络的无人管理引起的。3D细节理解题。由第七段内容可知，孩子们上网时父母实行有效控制可以使他们远离一些
29、不好的信息。4B推理判断题。本文主要讲述了电脑给人们工作及生活带来的不利影响，而这些影响都是人为造成的，因此，解决网络问题的关键是提高人们的道德水平。5D细节理解题。根据In most towns today, you can see teenagers standing.可知，teenagers指的是青少年young people而不是专指学生、女孩等。6A细节理解题。根据第二段They develop pains on their fingers because of the constant pressure.This condition is what doctors now call
30、 “Space Warriors Wrist”可知其根源是不停地压按钮。7C推理判断题。根据Another even more alarming problem is shown by the case of a 17yearold girl which was recently reported in the British Medical Journal.可知作者把这个情况称为更加令人惊恐的，说明作者不赞同青少年玩电子游戏。8B推理判断题。阅读全文可知玩电子游戏的主要是正处在长身体和学习的青少年，玩电子游戏富于刺激，但是侵占了学习时间，还会得“Space Warriors Wrist”等病，损害了身体健康。.1.It looks as if it will rain before long.2.I think it is no use telling her.3.Whats the language spoken in German？4.Which do you know is the most beautiful city？5.You will be likely to get there before 8 oclock.S
