Ⅳ知识点链接：

1.The long coat isn’t as small as the short coat.

Not as…as…表示甲在某一方面不及乙，常译为“不如……”.同义词组为not as …as…

Computers are very popular now and they are not as expensive as before.

思维拓展：

as… as…表示甲与乙在某一方面程度相同，译为“和……一样……”

I think foreign languages are as difficult as science subjects.

2.Things to do 要做的事情

此处to do为动词不定式作名词things的后置定语，要用不定式的主动形式。

I have a lot of homework to do today.

Do you have something to eat?

3.Yes, I do but I think the grey coat is my size.

Size n. “尺寸，大小”，既可用来表示物体的大小，又可用来表示服装、鞋帽的的尺寸、号码。

What size常引导特殊疑问句，用来询问尺码。

What size shoes do you want?

Size 36.

思维拓展：be of a size 同一大小

take the size of 量……的尺寸

Your bag is of a size with mine.你的包和我的包一样大。

The clerk took the size of my waist.店员量了我的腰围。

4.I don’t agree.

Agree译为“同意；赞同”，表示同意某人的观点、意见、计划、建议等。可以单独使用，也可以接with,to介词短语或从句。

Who agrees to this plan?谁同意这个计划？

辨析：agree with与agree to

①agree with表示“意见一致”，后面常接表示“人”的词或宾语从句，也可以接表示“意见”和“看法”的词。We all agree with him.我们都同意他的意见。

②agree to表示“同意；赞同”（特别指在不同意或争论之后），后常接表示“建议”或“计划”的名词；接动词原形时构成动词不定式结构。He agrees to go there.
