hows your new keyboard its as comfortable as the old one
How's your new keyboard? It's as comfortable as the old one.

答案

How's your new keyboard? It's as comfortable as the old one.

解析

【分析】本题要求正确抄写英文句子,需遵循英文书写的核心规则:一是句子开头单词首字母大写,缩写形式要正确使用撇号;二是根据句子类型添加合适的标点符号。首先观察原句:开头的“hows”是缩写,句首需大写为“How's”;前半句是疑问句,句末用问号;后半句的“its”是句首缩写,首字母大写为“It's”,后半句是陈述句,句末用句号,按此规则调整即可。
【解析】按照英文句子书写规范操作:1. 句子首单词“hows”改为大写缩写“How's”;2. 前半句为疑问句,句末加问号;3. 后半句“its”作为句首单词,首字母大写为“It's”;4. 后半句为陈述句,句末加句号,完成正确抄写。
【答案】How's your new keyboard? It's as comfortable as the old one.
【知识点】英文句子书写规范、大小写与标点使用
【点评】本题为基础抄写题,重点考察英文句子的大小写规则和标点符号的正确使用,难度较低,需学生细心留意细节即可完成。

2. 第二题第一空考查固定句型“It's + adj. + for sb. to do sth.”,需用动词不定式;第二空强调“已经成为生活重要部分”,是从过去延续到现在的结果,用现在完成时。
3. 第三题空格修饰动词“click”,需用副词形式,形容词easy的副词是easily。
4. 第四题第一空有“Look!”这一现在进行时的标志,结构为“be + 现在分词”,主语是单数,故用is searching;第二空“in ten minutes”表将来,用一般将来时。
【解析】
1. 由时间状语“in 1946”(过去时间)可知,此处用一般过去时,invent的过去式为invented,故填invented。
2. 第一空:固定句型“It's necessary for sb. to do sth.”中,需用动词不定式,故填to learn;第二空:强调动作对现在的影响(已成为重要部分),用现在完成时,主语they是复数,助动词用have,become的过去分词是become,故填have become。
3. 此处修饰动词click,需用副词,easy的副词形式为easily,故填easily。
4. 第一空:“Look!”提示动作正在进行,用现在进行时,主语my classmate是单数,be动词用is,search的现在分词是searching,故填is searching;第二空:“in ten minutes”表将来,用一般将来时,结构为will + 动词原形,故填will finish。
