Unit3 Comic strip—Welcome to the unit教材知识详解

1. An old friend of mine is coming to see me, Hobo.

霍波，我的一位朋友要来看我。

这里is coming相当于is going to come。英语里在谈到近期确定的安排时，常用进行时表达，这种用法比用将来时表达更为自然。常用于该用法的动词有come, go, leave等。如：

She is leaving soon. 她就要走了。

2. Is it enough for a tin of dog food?一罐狗食够吗？

be enough for (doing) sth.足够(做)……

如：100 yuan is enough for (buying) a cake.100元足够买一个蛋糕。

3. Wait a minute.等—会。

句中的wait是不及物动词，之后跟名词短语作状语。类似的说法有Just

a minute.请稍等。动词wait之后通常与介词for连用，构成词组wait for(等待）。如：

They are waiting for a school bus there.他们在那里等校车。

Time and tide wait for no man.岁月不等人。

4. Maybe we can order a pizza.也许我们能订一个比萨。

句中order是及物动词，意思是“定做、点菜”。在句中与情态动词can—起构成谓语。order之后跟名词或代词作宾语。如： I want to order a new suit.我想定做一套新衣。 —What would you like to order?你想点什么菜？ Unit 3 Welcome to Sunshine Town

Unit 4 Don’t eat in class.
