(not) to do sth.告诉某人（不要）做某事，固定结构；根据句意语境，可知选D。 4．A 【解析】句意：——那是我的帽子。请把它给我。 ——好的。 考查give的用法。固定短语give sb. sth.=give sth. to sb. “给某人某物”，在give sb. sth.结构中sth.不能用代词。故选A。 5．D 【解析】句意：史密斯先生向他的朋友们展示他的新车。他们说这是一辆好车。 考查动词短语辨析。固定短语show sth. to sb.=show sb. sth.“给……看”，可排除AC选项；又因Mr. Smith是单数第三人称，动词show需用三单形式，故选D。 6．B 【解析】句意：请把你的尺子借给我，把它扔给我。 考查固定搭配。throw sth to sb, 表示把某物扔给某人，故选B. 7．C 【解析】句意“我不喜欢这个，你能给我另一个吗？”。空前有could，用动词原形，排除A和D；根据show sb sth=show sth to sb可知，故选C。 8．D 【解析】句意：拿走这个脏衬衫，给我拿个干净的来。 考查动词词义辨析。bring带来；take带走。“take away”表示“带走”；根据“...me a clean one”可知，把某物从另一个地方带到说话的地方来，应用“bring”。故选D。 9．C 【解析】句意：你能给我看看你的照片吗？ 考查show的用法。短语show sb. sth.= show sth. to sb.“把某物展示给某人看”；只有C的结构是正确的，故选C。 10．B 【解析】试题分析：句意：--在英语方面我有一些问题。--不要担心。我能为你提供帮助。offer sb sth="offer" sth to sb为某人提供某物，情态动词后加动词原形，结合句意，故选B。 考点：考查动词短语的用法。 11．B 【解析】句意：——我想读放在那里的那本书。请你把它递给我好吗？——当然，给你。 Pass sth to sb.意为“将某物递给某人”，pass后接双宾语，另一个搭配是pass sb sth，其他的搭配都错误；故选B。 12．D 【解析】试题分析：句意：今天是我女儿的第五个生日，我为他买了一个玩具小汽车。表示某人的第几个生日用序数词。故第一个空用fifth；短语buy sth. For sb.表示为某人买某物。根据题意，故选D。 考点：考查序数词及介词。 13．D 【解析】句意：她想在我的生日的时候给我买一个MP3。 考查动词短语。这里是短语want to do…想要做某事；故排除AC；buy sth for sb为某人买某物。故选D。 14．C 【解析】句意:这是Lucy的书，请把它给她。 考查动词后接双宾语的用法。give“给”的意思，后面可以接双宾语give sb. sth.“把某物给某人”，也可以转换为give sth. to sb.。但是如果短语中sth.是代词it或them，则代词只能放在give后，用give it/them to sb.句式。故选C。 15．A 【分析】 【解析】句意：——为何不给约翰买一个玩具小汽车来作为他的生日礼物呢？——好主意。他对汽车很是痴迷。 考查固定句型。“Why not

【解析】句意：对某事产生兴趣可以使你的大脑更加活跃。 考查非谓语动词以及形容词和副词。根据“...an interest in something can make your brain...”可知，句子缺少主语，因此此处应使用动名词作主语，故排除选项A与选项C；make后跟形容词作宾语补足语。故选B。 18．B 【解析】句意：在老师的帮助下，所有学生都欣喜地发现数学题更简单了。 考查形容词作宾补以及形容词比较级。句型结构“find sth. adj.”意为“发现某事如何”，其中adj.为形容词作宾语补足语。根据语境，强调老师帮助前后的对比，帮助后数学题的难度比帮助前更简单，所以应使用easy的比较级，即easier。故选B。 19．C 【解析】句意：我们现在正经历一段非常艰难的时期，但我们仍然需要保持希望。 考查形容词辨析。closed关着的；live活的；alive仍然存在的；close靠近的。根据“but we still need to keep hope ...”可知要继续保持希望，用alive作宾语补足语。故选C。 20．A 【解析】句意：中国高速铁路是惊人的。它使旅行更快更舒适。

考查keep的用法。cleaned一般过去时；cleaning动名词，现在分词；clean动词原形，形容词；cleans三单；keep+形容词，表示“保持……的状态”，分析句子“keep the environment ”所以此处是保持环境清洁，用形容词，故选C。 22．D 【解析】句意：当我经过教室时，我看见一个女孩在里面画画。 考查现在分词作补足语。draw画画（动词原形）；losing丢失（现在分词）；drew画画（过去式）；drawing画画（现在分词）。根据“When I passed the classroom, I saw a girl…”可知，与之同时发生的动作see是一般过去时，并且“see看见”的内容是正在进行的动作。表达“看见某人正在做某事”用see sb. doing sth.，doing sth.作宾语补足语。选项D“画画”符合语境。故选D。 23．A 【解析】句意：——你叔叔在干什么？——他正在看那儿的孩子们用报纸制作飞机。 考查非谓语动词。watch sb doing sth“观看某人正在做某事”，watch sb do sth“观看某人做某事的全过程”，根据语境可知，是看孩子们正在做的事情， 用现在分词making作宾补。故选A。 24．D 【解析】句意：她大约花了一个月完成她的报告。她工作真的很努力。 考查动词短语搭配。spend+时间/钱+in+doing sth.花费时间或金钱做某事，其中介词in可省略，故填complete的现在分词形式，故选D。 25．D 【解析】句意：港珠澳大桥长55公里，工人们花了5年规划，9年建成。 考查spend用法。plan计划；build修建。根据“the workers

jumping现在进行时；jumping动名词，现在分词；jumped过去式；to jump动词不定式；see sb. do 看见某人做某事，强调看到整个过程；see sb. doing 看见某人正在做某事；根据“While I was walking along the river”可知当我沿着河边走的时候，此处是正在做什么，所以用doing，故选B。 【点睛】see sb. do 看见某人做某事，它的语句环境是“主语对象”完整的目睹了某人做某事的全过程，强调了“主语对象”对该事件的完整了解性；see sb. doing 看见某人正在做某事，它的语句环境是“主语对象”恰巧看到了某人正在实施某事，强调的是看见的这么一个动作，是一个瞬间发生的事情。本题就是强调看见正在做某事，所以用doing。 28．C

【解析】根据中英文对照可知，空处缺“想知道是否”的英文。本句为宾语从句，wonder“想知道”谓语动词，因是陈述现在想法，故主句时态为一般现在时，主语为I，谓语动词用原形；whether...or not表示“是否”，固定搭配，其中whether为宾语从句引导词。故填wonder；whether。 49． to search for information 【解析】根据句意可知，句中缺少“搜索信息”的表达；search for搜寻，动词短语；information信息，不可数名词；句中使用短语“use sth. to do sth.用……来做某事”。故填to search for information。 50． have more time do housework 【解析】通过中英文句子对比可知，英文句子中缺少“有更多时间”和“做家务”的表达；“有更多时间”英文表达是have more time，will后接动词原形have；“做家务”英文表达是do housework，help sb. do sth.固定搭配“帮助某人做某事”，所以这里do用动词原形。故填have；more；time；do；housework。 51． helps get ready for 【解析】根据语境可知，句子时态为一般现在时，第一个空是谓语动词“帮助”，用help表示，由于主语“A big breakfast”是第三人称单数，谓语动词应加s变为helps；get ready for...表示“为……做好准备”，放在宾语him后作宾语补足语，根据help sb. (to) do sth.“帮助某人做某事”可知，第二个空get用原形即可。故填helps；get；ready；for。 52． helps get ready for 【解析】对照中英文可知，句子时态是一般现在时，缺少谓语动词help“帮助”和宾语补足语get ready for“为……做好准备”；主语A healthy breakfast是第三人称单数，因此第一个空help需加s；根据help sb. (to) do sth.的结构可知，第二个空用动词原形get即可，第三和第四个空根据固定短语分别填ready和for。故填helps；get；ready；for。 53． do the dishes 【解析】根据汉语提示，可知用动词短语help sb. (to) do意为“帮助某人做某事”，其中的不定式符号to可以省略；do the dishes“清洗餐具”，根据空格的数量，故填do；the；dishes。 54． playing happily 【解析】结合“看到一些孩子正在花园里高兴地玩耍”，可知此处需用saw sb. doing sth.“看见某人正在做某事”；play“玩”；happily“高兴地”副词修饰动词。故填playing；happily。 55． on the blackboard 【解析】根据中英文对比，这里缺少“在黑板上”的意思，“on”表示“在……上面”；“blackboard”表示“黑板”；名词blackboard前面用冠词“the”修饰。故填on；the；blackboard。 56． no order 【解析】根据中英文对照可知，此处应用“no+名词”结构，order“秩序”。故填no；order。 57． made you angry 【解析】使某人……make sb +adj, 形容词做宾语补足语，生气的angry, 时间状语是yesterday, 说明是一般过去时，故填made you angry。 58． both on and off 【解析】根据中英文对照，空格处缺“不管是……还是……”，both...and...，固定搭配，用于连接两个并列成分，表示“两者都”；“在球场上”用on，“球场下”用off。“both on and off the field”准确表达“不管是在球场上还是球场下”。故填both；on；and；off。 59． Both and drinking fish soup 【解析】根据中英文对照可知，句中缺少“二者都……”和“喝鱼汤”的英文内容，“both...and...”是固定搭配，表示“两者都……”，用于连接两个并列主语Sam和Tom，“both”位于句首，首字母大写；“like doing sth.”表示“喜欢做某事”，“drink”的动名词形式为“drinking”，“鱼汤”英文为“fish soup”。故填Both；and；drinking；fish；soup。 60． Both and come true 【解析】根据中英文对照可知，both…and…“……和……都”，连接主语relatives和friends，句首首字母大写。come true“实现”，动词短语。make sth. do“使某事……”，come用其原形。故填Both；and；come；true。 61． brought his knowledge and skills 【解析】bring…to…“把……带到……”，句子时态为一般过去时；his“他的”；knowledge“知识”；and“和”；skills“技能”。故填brought；his；knowledge；and；skills。 62． but feel confident 【解析】根据中英文对照可知，but“但是”，表示转折；feel“感觉”，空前有助动词，动词用原形；confident“自信的”。故填but；feel；confident。 63． I’d love to but 【解析】根据中英文提示可知，此处“I’d love to”表示“我很乐意”；“but”表示“但是”。故填I’d；love；to；but。 64． so more and more 【解析】根据句意可知，此处表示“因此，越来越多的人喜欢驾驶它们”，so表示“因此”；用“比较级+and+比较级”表示“越来越……”，many表示“多的”，比较级为more。故填so；more；and；more。 65． Why do so much Because cute 【解析】空一表示“为什么”，英文是why，首字母大写；主语是you，空二应填助动词do构成疑问句结构；空三、空四表示“如此”，用短语so much表示；空五表示“因为”，英文是because，引导原因，首字母大写；空六表示“可爱”，英文是cute，形容词作表语。故填Why；do；so；much；Because；cute。 ( 1 / 2 )学科网（北京）股份有限公司 学科网（北京）股份有限公司 $
