My Invention
Hello, everyone! Now let me introduce my invention to you.









答案

范例:
My Invention
Hello, everyone! Now let me introduce my invention to you.
I had an invention last term. I call it the Self-acting Cleaning Robot. It is round, like a plate. It's mainly made of plastic. It is used to clean up our classroom and other places. When we have classes, it stands at the corner of the classroom quietly. It cleans the room after we leave it.
Why can it do so? Because it is controlled by a small computer inside it. It can know when we are in and when we are out. And the movement path of the robot is set before using.
Is it amazing?

一、根据句意,从方框中选择适当的词并用其正确形式填空。
instruct broad passport
wool wake
1. Every day, Mom
wakes
up early in the morning and prepares breakfast for the whole family.
2. She likes wearing

5. Reading more books and practicing more
broaden
my knowledge and experience.

答案

1. wakes 2. woolen 3. instructions
4. passport 5. broaden

解析

【分析】本题为词汇适当形式填空题,解题思路为:先理解每个句子的句意,再分析空缺处所需的词性,结合方框内的词汇,根据语法规则(时态、主谓一致、词性转换等)对词汇进行变形,最终填入符合语境的正确形式。
【解析】1. 句中时间状语every day表明用一般现在时,主语Mom是第三人称单数,固定搭配wake up意为“醒来”,因此将wake变为第三人称单数形式wakes。2. 空后是名词sweaters,需用形容词修饰,方框内名词wool的形容词形式为woolen,意为“羊毛制的”,符合句意。3. 句意要求“遵循机器的说明”,动词instruct的名词形式为instruction,常用复数形式instructions表示“说明、指南”,故填instructions。4. 出国旅行前需准备护照,名词passport在此处用单数形式,符合语境。5. 句意是“多读书多练习拓宽知识和经验”,形容词broad的动词形式为broaden,意为“拓宽”,主语是两个并列的动名词短语,视为复数,故用动词原形broaden。
【答案】1. wakes 2. woolen 3. instructions 4. passport 5. broaden
【知识点】动词形式变化、形容词转换、名词复数
【点评】本题考查英语词汇的词性转换及语法运用,需结合句意和语法规则对词汇进行适当变形,属于基础题型,注重词汇的灵活运用,难度适中。

【分析】
本题考查同根词的不同词性用法,解题思路为:先分析每个空格在句中充当的成分,确定所需词性,再结合同根词的词性转换规则选择正确形式。具体来看:1. 第一空修饰名词需用形容词,第二空作谓语需用动词;2. 第一空在不定式符号后需用动词原形,第二空修饰名词需用形容词;3. not only...but also连接并列成分,需用相同词性;4. 第一空修饰名词需用形容词,第二空表材料需用名词;5. 空格作谓语需用动词,结合主语单复数确定形式。
【解析】
1. 第一空修饰名词sunlight,用形容词light(明亮的);第二空作谓语,主语sunlight为单数,动词用第三人称单数形式lightens(照亮),故填light; lightens。
2. 第一空在began to后,用动词原形darken(变暗);第二空修饰名词room,用形容词dark(黑暗的),故填darken; dark。
3. not only...but also连接并列谓语,前面是动词原形open,后面需用动词原形widen(拓宽),故填widen。
4. 第一空修饰名词toy gun,用形容词wooden(木制的);第二空表示制作材料,用名词wood(木头),故填wooden; wood。
5. 主语days为复数,空格作谓语需用动词原形shorten(变短),故填shorten。
【答案】
1. light; lightens 2. darken; dark 3. widen 4. wooden; wood 5. shorten
【知识点】
词性转换;词汇用法
【点评】
本题围绕同根词的词性转换展开,核心是判断句子成分以确定所需词性,属于基础词汇题,需学生掌握常见词缀(如-en)构成动词的规则,难度适中。
