专题01 Unit 2（语法综合练） （建议用时：40分钟） 一、单项选择 1.________ amazing idea the student came up with for his science experiment! A. How B. What C. What a D. What an 【答案】D 【详解】本句句意为“这个学生为他的科学实验想出了一个多么绝妙的主意！”。本句为感叹句，核心看后面的中心名词idea，属于可数名词单数。amazing发音以元音音素开头，搭配不定冠词an，所以用What an。How只能用来修饰形容词或副词，不能直接带名词短语，其余选项句式搭配均不成立。 2.________ put any metal tools into the water experiment bowl. It is dangerous. A. Don’t B. Not C. No D. Doesn’t 【答案】A 【详解】本句句意为“不要将任何金属工具放入实验水盆中，这很危险。”。这是否定祈使句，日常做题直接记固定结构：Don’t + 动词原形，用来表示劝阻、禁止。Not和No不能直接放在动词前否定，Doesn’t只用于陈述句的三单否定，都不符合祈使句用法。 3.— ________ you finish your experimental report yesterday? — Yes, I finished it on time. A. Do B. Did C. Will D. Are 【答案】B 【详解】本句句意为“你昨天完成实验报告了吗？——是的，我按时完成了。”。句中有明显过去时间状语yesterday，整句话用一般过去时。句中finish是实义动词，对应的过去式一般疑问句要用助动词Did开头。Do用于现在时，Will用于将来时，Are是系动词，都不匹配本句时态和结构。 4.________ carefully the teen inventor checked every part of his new device! A. What B. What a C. How D. How an 【答案】C 【详解】本句句意为“这位少年发明家多么仔细地检查了他新装置的每一个零件！”。本句用来感叹的是副词carefully，修饰动作check。感叹句用法里，How专门修饰形容词、副词，What只能修饰名词短语，所以这里只能用How，其余选项结构均错误。 5.Tell me, is the new tool made of wood ________ plastic? A. or B. and C. but D. so 【答案】A 【详解】本句句意为“告诉我，这个新工具是木头做的还是塑料做的？”。本句是选择疑问句，句式特点就是用or连接两个可供选择的选项，表示“或者、还是”。and表并列，but表转折，so表因果，都不符合选择疑问的语境。 6.The inventor ________ satisfied with his first experimental result. He decided to do it again. A. was not B. is not C. did not D. will not 【答案】A 【详解】本句句意为“这位发明家对他第一次的实验结果不满意，他决定重新做一次。”。be satisfied with 是固定搭配，表示“对……满意”，这个短语必须和be动词连用。后半句decided提示整件事发生在过去，时态统一为一般过去时，主语为单数，否定形式用was not。 7.________ be brave and keep trying when you fail in your invention practice. A. Do B. Does C. Is D. Are 【答案】A 【详解】本句句意为“当你在发明实践中失败时，一定要勇敢、坚持尝试。”。本句是祈使句，Do放在句首可以加强语气，表强调“务必、一定”，后面始终跟动词原形。Does、Is、Are都不能用于祈使句的强调结构，属于常见易错点。 8.— ________ did you get the idea of your water-saving invention? — From daily life problems. A. How B. What C. Who D. Which 【答案】A 【详解】本句句意为“你是如何想到节水发明这个点子的？——从日常生活的问题中。”。答语交代的是获取创意的方式、途径，对方式提问统一用How。What问事物、Who问人物、Which问具体选择，和本句语境不匹配。 9.________ wonderful scientific principle Archimedes discovered years ago! A. What a B. What C. How D. How a 【答案】A 【详解】本句句意为“阿基米德多年前发现的科学原理多么精妙啊！”。本句感叹的中心词是principle，为可数名词单数，且wonderful发音以辅音音素开头，用What a修饰最合适。What后接复数名词或不可数名词，How修饰形容词、副词，How a属于错误结构，均可直接排除。 10.________ ignore small details, or you will miss important scientific rules. A. Don’t B. Not C. No D. Never 【答案】A 【详解】本句句意为“不要忽略细小的细节，否则你会错过重要的科学规律。”。日常考试高频考点，否定祈使句统一用 Don’t + 动词原形，用来提醒、告诫对方不要做某事。Not、No、Never都不能直接加动词原形构成规范祈使句。 二、用所给单词的适当形式填空 1. The young scientist ________ (fool) no one and showed his real experimental result yesterday. 【答案】fooled 【详解】句意：这位年轻的科学家没有欺骗任何人，如实展示了他的实验结果。句中有yesterday，明确表示过去发生的动作，谓语动词要用过去式。and连接两个并列动作，后面showed为过去式，前面fool也要变形为fooled。 2. Practise ________ (observe) daily life, and you will get more great ideas. 【答案】observing 【详解】句意：坚持观察日常生活，你会收获更多绝妙的想法。practise 后面只能接动名词，是课本固定用法，practise doing sth. 表示“坚持/练习做某事”，所以这里填observing。 3. This new device can ________ (displace) less air than the old one. 【答案】displace 【详解】句意：这款新装置排出的空气比旧装置更少。can是情态动词，情态动词后的实义动词一律用原形，这是基础固定规则，因此直接填displace。 4. The student feels ________ (complete) confident about his school invention show. 【答案】completely 【详解】句意：这名学生对自己的校园发明展示充满信心。confident 是形容词，修饰形容词需要用副词，complete的副词形式是completely，用来加强程度，表示“完全充满信心”。 5. Many ancient ________ (thinker) created great ideas that change the world. 【答案】thinkers 【详解】句意：许多古代思想家提出了改变世界的伟大思想。many 后面必须接可数名词复数，thinker 为可数名词，复数形式直接加s，变为thinkers。 6. She ________ (fill) three bowls with water to do the small experiment last week. 【答案】filled 【详解】句意：上周她装了三碗水来做这个小型实验。last week 提示整句为过去时态，fill 属于规则变化动词，过去式为filled，同时贴合单元 fill…with 固定搭配。 7. We are ________ (satisfy) with the creative design of the teen inventor. 【答案】satisfied 【详解】句意：我们对这位少年发明家的创意设计很满意。be satisfied with 是本单元核心固定搭配，考试高频短语，直接用来表达“对……感到满意”，无需变形。 8. Doing small experiments is a ________ (wonder) way to develop creativity. 【答案】wonderful 【详解】句意：做小型实验是培养创造力的绝佳方式。空格后是名词way，修饰名词要用形容词，wonder 的形容词形式为wonderful，用来修饰事物、方式。 9. The boy kept ________ (think) about his new invention all night. 【答案】thinking 【详解】句意：这个男孩整晚都在思考他的新发明。keep doing sth. 是固定用法，表示“持续做、一直做某事”，后面动词统一用动名词形式，所以填thinking。 10. These new ________ (discovery) help students understand science better. 【答案】discoveries 【详解】句意：这些新发现帮助学生更好地理解科学。these 指代复数概念，后面可数名词要用复数，discovery 变复数需要变y为i加es，即discoveries。 11. Many great ________ (invent) change people’s lives greatly in modern society. 【答案】inventions 【详解】句意：许多伟大的发明极大地改变了现代人的生活。many后接可数名词复数，invent为动词，其名词形式invention表示“发明物”，复数形式为inventions。 12. We should learn to think ________ (creative) in our daily study. 【答案】creatively 【详解】句意：我们在日常学习中要学会创造性地思考。此处修饰动词think，需要用副词，creative的副词形式是creatively。 13. The old scientist ________ (devote) all his life to scientific research years ago. 【答案】devoted 【详解】句意：这位老科学家多年前将毕生精力投入到科学研究中。years ago提示句子为一般过去时，devote的过去式为devoted。 14. It is ________ (possible) to finish the complex experiment in such a short time. 【答案】impossible 【详解】句意：在这么短的时间内完成这个复杂的实验是不可能的。结合语境，此处表达否定含义，possible的反义词为impossible，意为“不可能的”。 15. Keep on ________ (explore) unknown fields, and you will get new ideas. 【答案】exploring 【详解】句意：坚持探索未知领域，你会收获新的想法。keep on doing sth. 为固定搭配，意为“坚持做某事”，后接动名词形式。 16. The teacher encouraged us ________ (share) our creative ideas with classmates. 【答案】to share 【详解】句意：老师鼓励我们和同学分享自己的创意。encourage sb. to do sth. 是固定用法，意为“鼓励某人做某事”。 17. His ________ (observe) of natural phenomena helped him finish the new invention. 【答案】observation 【详解】句意：他对自然现象的观察帮助他完成了这项新发明。形容词性物主代词his后接名词，observe的名词形式observation表示“观察”。 18. All the students felt ________ (excite) when they saw the amazing invention show. 【答案】excited 【详解】句意：所有学生看到精彩的发明展示时都十分兴奋。修饰人要用-ed形容词，excited表示“感到兴奋的”。 19. Scientific ________ (achieve) always come from continuous thinking and practice. 【答案】achievements 【详解】句意：科学成就往往源于不断的思考和实践。谓语动词为原形come，说明主语是复数，achieve的名词复数形式为achievements。 20.
