译林版六上 Then and now知识点

U4 Then and now1 can的用法Now he can do many things. 现在他会做许多事情。

解析can 为情态动词，后接动词原形，其过去式为could。

在将含有can的句子改为否定句时，在其后加否定词not；改为一般疑问句时，将can提到句首，句末用问号。

Liu Tao can play basketball. 刘涛会打篮球。

I could not write emails three years ago. 三年前我不会写电子邮件。

2 write letters to...的用法Twenty years ago,Mr Brown wrote letters to his friends.二十年前，布朗先生写信给他的朋友们。

解析write letters to...意为“写信给·····”，也可以省略letters 直接写成write to...。

write的过去式为wrote。

例句I am writing to my pen friend. 我在给我的笔友写信。

3.buy...from的用法She bought things from shops. 她从商店买东西。

解析buy...from意为“从······买····..”。

buy的过去式为bought。

表示“买东西给某人”用短语buy sb sth.或buy sth for sb.。

I bought a storybook from the bookshop. 我从这个书店买了一本故事书。

My son often buys toys from the supermarket. 我儿子经常从这个超市买玩具。

4不规则动词过去式的用法有实义动词的一般过去时的句子在改为否定句时，在动词前面加上didn’t，原来动词的过去式要改为动词原形。
