A．of; to B．for; to C．of; for D．for; for 【答案】B 【详解】句意：对于他来说，去帮助他的同学是有益的。 of属于……的；to向，动词不定式符号；for为了。此处考查固定句型：It’s + adj. + for/of sb. + to do sth.中介词的辨析。形容词helpful表示事物的性质而非人的性格特征，第一空介词用for；句型中真正的主语是动词不定式，第二空用to。故选B。 15．It ________ a big problem ________ many animals lose their homes. A．is; that B．are; to C．is; to D．are; that 【答案】A 【详解】句意：许多动物失去家园是一个大问题。 主语It为第三人称单数，第一个空应用is；第二个空后为完整句子，应用连接词引导从句，to是介词，排除。分析句子结构可知，It是形式主语，该从句是真正主语，从句句意完整、不缺成分，用that引导主语从句，无实际含义，仅起连接作用。 16．It’s amazing ________ we have built such a great project in a short time.

(连词成句) _________________________ 【答案】It’s no secret that Chinese love tea 【详解】根据所给标点可知是陈述句。分析所给单词，it’s它是；that引出从句；no没有；love喜欢；secret秘密；tea茶；Chinese中国人。It’s no secret that+从句，意为“……不是什么秘密”，主语从句句型，it为形式主语，that之后的句子为真正的主语，因此that之后的句子为“中国人爱茶”，即“Chinese love tea”。故填It’s no secret that Chinese love tea 意为“中国人爱茶已经不是什么秘密了”。 23．你没有来参加晚会，真是一个遗憾。 ____________________ you didn’t come to the party. 【答案】It’s a pity that 【详解】根据中英文对照可知，空格处缺少“真是一个遗憾”，其对应英文it’s a pity，后跟that引导的主语从句，句首字母要大写。故填It’s a pity that。 24．毫无疑问，他完全符合担任这项工作的条件。 ________ ________ ________ ________ he is well qualified for the job. 【答案】 It is undoubted that 【详解】根据“he is well qualified for the job”可知此处应为that引导的主语从句，因此主语应是it作形式主语，位于句首，首字母要大写，句子采用一般现在时，谓语be动词应用is，“毫无疑问”应用形容词undoubted来作表语。故填It；is；undoubted；that。 25．It is necessary for volunteers to be kind. (改为否定句) It is ________ necessary for volunteers ________ ________ kind. 【答案】 not to be 【详解】句意：志愿者有必要善良。原句是“It is+形容词+for sb. to do sth.”的句型，改为否定句时，直接在is后加not，同时保留不定式结构to be。 26．For me, doing homework is easy. (改为同义句) It is ________ for me ________ ________ my homework. 【答案】 easy to do 【详解】句意：对我来说，做作业很容易。原句是动名词作主语的结构，同义转换为“It is+形容词+for sb. to do sth.”的句型，其中形容词为easy，不定式为to do。 27．你能帮我拎这个重箱子，真是太善良了。 It is very kind ________ you ________ ________ me carry the heavy box. 【答案】 of to help 【详解】对照中英文可知，缺少“帮助”和“对……来说”。help是动词，意为“帮助”。本句为“It is + adj. + of sb. to do sth.”句型，形容词kind描述人的品质，应用介词of，形容词后需接不定式to do。 28．对我们来说每天锻炼很重要。 It is important ________ us ________ ________ exercise every day. 【答案】 for to take 【详解】根据句型It is important for sb. to do sth.意为“对某人来说做某事很重要”，for引出对象，us是人称代词宾格，后接不定式表示具体的动作；take exercise“做运动”。 29．对孩子们来说在河里游泳是危险的。 It is dangerous ________ children ________ ________ in the river. 【答案】 for to swim 【详解】It is +adj. +for sb+to do sth 意为“对于某人来说，做某事是……的”。句中It是形式主语，形容词dangerous描述的是 “在河里游泳” 这件事的危险性，因此用for sb. 引出动作对象，①处填for； 句子的真正主语是“游泳”，需要用不定式形式to swim，因此②处填不定式符号 to，③处填动词原形swim。 30．嘲笑弱者是错误的。 It’s ________ ________ laugh at the weak. 【答案】 wrong to 【详解】原文中“错误的”是关键词，这是it’s adj. to do的结构，wrong表示错误的，故第一空填wrong，第二空填to。 一、语法选择 请通读下面短文，掌握其大意，根据语法和上下文连贯的要求，从每小题所给的三个选项中选出一个最佳答案。 Huang Xuhua, a great scientist, is widely known as the “Father of China’s Nuclear Submarine (核潜艇).” He was born in Guangdong in 1926.
