1、很多國(guó)家都存在環(huán)境問(wèn)題。

Many countries have environmental problems.

Environmental problems exist in many countries.

敲黑板：

陳述句：誰(shuí)干什么。 誰(shuí)：名詞? ? 干什么：動(dòng)詞??

先結(jié)構(gòu)再關(guān)系：把握句子主干，其他為修飾成分。

寫作源于模仿，記住的意群越多，越native。例如：environmental problems、have problems、problems exist。

2、環(huán)境問(wèn)題已經(jīng)越來(lái)越嚴(yán)重。

Environmental problems have become increasingly severe.

Environmental problems are going from bad to worse.

敲黑板：

環(huán)境問(wèn)題 environmental problems、environmental woes、 environmental issues。

3、出國(guó)留學(xué)可以讓人學(xué)習(xí)外語(yǔ)。

Studying overseas allows people to learn foreign languages.

敲黑板：

allow sb to do sth=? enable sb. to do sth. 讓某人做某事

study overseas/abroad 出國(guó)留學(xué)

doing sth. 做主語(yǔ) 謂語(yǔ)動(dòng)詞用單數(shù)

learn/acquire foreign languages 學(xué)習(xí)外語(yǔ)? ? 不用 study 意為研究?
