3、ks to the workers great efforts, the construction work was completed ahead_ schedule.答案:1.be considered句意:考查被动语态。句意:我们行动前应该考虑市场可能的反应。分析句子结构可知,consider 和句子的主语 reactions 之间是被动关系,所以用被动语态。2.of 句意:考查固定搭配。句意:大多数青少年不知道玩电脑游戏的坏影响。be aware of 知道。3.where句意:考查宾语从句。句意:我们还没有讨论把我们的新家具放在哪里。空处引导宾语从句,从句中缺少地点状语,故填 whe

4、re。4.scared句意:考查词形转换。什么使你那么害怕?房间外面可怕的声音。scared“害怕的,恐惧的”,在此是形容词作宾语补足语。5.that 句意:考查定语从句。句意:泰山是我攀登过的最漂亮的山之一。空处引导定语从句,修饰先行词 mountains,因先行词前有最高级修饰,故用 that。6.What 句意:考查感叹句。句意:你上周借给我的书多么有用啊!中心词是 book,所以此处要用What。7.couldnt have solved句意:考查虚拟语气。句意:要不是你的帮助,我不可能解决那个问题。此处是含蓄虚拟语气且表示与过去事实相反,结合句意可知应填 couldnt have s

5、olved。8.sharply 句意:考查副词。句意:据报道气温一两天内会急剧下降。分析句子结构可知,空处修饰动词 decline,所以用副词形式。9.bleeding句意:考查非谓语动词。如果我看到有人受伤该怎么做?你必须先给他止血。stop sb.(from)doing sth.“阻止某人做某事”,所以填 bleeding。10.of 句意:考查固定搭配。句意:由于工人们的巨大努力,建筑工程提前完成。ahead of schedule提前。.单句改错1.Your performance as a student will be excellent if you develop a habi

8、you develop a habit of reflecting how you learn.句意:如果你养成了思考如何学习的习惯,那么作为学生你的表现将会是优秀的。reflect on/upon 思考。2.You ought to aware how risky this investment is.句意:你应该知道这种投资是要冒很大风险的。aware 是形容词,必须与 be/become 连用。ought to 后应接动词原形。3.We were beated in that match.句意:在那场比赛中我们惜败。过去分词前应用副词。4.She was when she found h

9、er room upside down.句意:当她发现她的房间乱七八糟时,她很害怕。人作主语时表语应用过去分词式的形容词。5.The law prevents everyone being attacked.句意:法律防止每个人受到攻击。prevent sb. from doing 阻止/防止某人做某事。该结构中的from 可省,但如果是被动式则 from 不能省。6. fine, well go outing.句意:如果天气好的话,我们将去郊游。分析题干可知,句子的主语与分词短语的逻辑主语不同,因此应用独立主格结构 it 指代天气。7.With the electric map in the

10、 car showing the exact position, the driver can drive in the right direction to the destination.句意:一张电子地图被安装在汽车里显示准确的位置,司机能朝正确方向行驶到达目的地。the electric map 与 fix 之间为被动关系,故用过去分词作宾补。8.The human body is made up of organs, each a definite job to do.句意:人体由器官组成,每个器官都有明确的分工。each having 为独立主格结构。9.The moon shin

11、es with light.What a good night!根据常识,月亮自己不发光,而是反射太阳的光,应用过去分词表达。10.The house was turned upside to down.句意:房子被翻得乱七八糟。upside down 副词,无需加介词。on/uponBeing It beingfromscaring scarednarrow narrowly be reflecting reflectedfixing fixedhas having.完形填空(2016南京金陵中学高二模拟)All water, even rain water, contains dissol

20、D.resource19.A.witness B.see C.explain D.express20.A.problems B.matter C.situations D.questions答案:1.解析:D 海水是咸的,应该是从味觉上感觉到的。因此要选择 D 项。2.解析:B 海水是咸的还是淡的要根据个人的判断 因此要选择 B 项。respectable 体面的;有身份的;individual 个人的;collective 集体的;annual 每年的。3.解析:B在做这个决定的时候,人们更加相信通过味觉而不是通过做试验(而得到结论)。be convinced 相当于 believe,而此处

21、有 is,因此要选择 B 项。其他两项意思不对。4.解析:C 此空和前面的 accept 相对应,因此选择 reject。 abandon 抛弃;reject 拒绝;receive接受;object 反对,对持异议。5.解析:A 从后文来判断,应该是用 glass 装水。因此只能选择 A 项。6.解析:D 从文章来看,这杯水没有加盐,为自然状态下的水,因此要选择 D 项。normally正常地;regularly 定期地,有规律地; artificially 人工地;naturally 自然地。7.解析:B 从上文看加了些盐,因此有些咸。所以要选择 B 项。8.解析:A salt 为不可数名词

22、,不能用 number 来修饰。quality 为“质量” ,total 为“总数”,均不符合题意。9.解析:B addto 是固定搭配,意为“把加到之上”。10.解析:C 从上文来看“第三杯水太咸了不能喝,这杯水和海水的盐的容量一样 ”,因此很明显海水要比我们日常使用的水含更多的盐,所以此处要选择 C。11.解析:D 从上文可知“这水太咸”不适合饮用,因此为“不可接受的量”,故选unacceptable。unbelievable 难以置信的;abnormal 不正常的; imaginable 可想象的。12.解析:B 此处表示“ 海水里含有多达的盐”,因此用表示数量且修饰不可数名词的much

23、。13.解析:A 如果海水里的盐被移出来,撒在地上的话 remove 把移到别处;abandon放弃,遗弃;move 移动;produce 生产。因此要选择 A。14.解析:B 句意:形成 500 多英尺厚的一层此处强调盐多,积累得厚,因此要选择thick。15.解析:C arouse ones curiosity“激起某人的好奇”。其他三项均不和 curiosity 搭配。16.解析:D 激起科学家兴趣的不是为什么海水那么咸,而是为什么它不和流入它的河流一样淡。因此要选择 D。17.解析:A 由上文知“河流的水和海水相比是淡水”,因此要选择 fresh。18.解析:B 此处表示:什么是海水和

24、它的盐的根源呢 ?rule 规则;origin 根源,起源;base 基础;resource 资源。19.解析:C 衔接上文,此处一连提出三个问题,以待科学家解释。因此要选择 C。20.解析:D 此处表示“要回答相关的问题”。四个选项中只有 D 项和 answer 可以搭配。因此要选择 D。.阅读理解People travel for a lot of reasons.
