1. used to do sth. 表示\"过去常做某事\"; be / get used to (doing) sth. 表示\"习惯于做某事\"。例如:
I used to smoke, but I have given it up two years ago.
He is used to doing some exercises before breakfast.
2. 句型\"so + 连系动词 / 情态动词 / 助动词 +主语\"是主谓倒装结构,表示所提到的情况与前面的相同,其中so代表上文中所叙述的情况,表示\"也是这样、也是如此\"。例如:
You went home yesterday. So did I.( = I went home, too.)
与此句型相似的结构\"so + 代词(主语)+连系动词 / 情态动词 / 助动词\",是正常语序,表示说话人同意或赞同对方所说的情况,主语与前句的主语一致。意思为\"是的;确实如此\"等。例如:
A: He is a good boy.
B: So he is. (是的。)
3. although引导让步状语从句,意为\"尽管\"、\"虽然\"。汉语中\"虽然......,但是......\"常连用,而英语中although不能与but连用,二者在同一句子中只能用其一。例如:
Although he is not rich, he is happy. / He is not rich, but he is happy.
4. not only..., but also...意为\"不但......,而且......\",用来连接两个并列的成分,当连接两个并列主语时,谓语动词一般与后一个主语在人称、数上保持一致。例如:本}文←内容摘$自wWW.chiNESeJY.COM中 国 教 育资源 网
Not only you but also I am wrong.
5. 21-year-old是由\"数词 + 名词 + 形容词\"构成的复合形容词。当其中词与词之间使用连字符后,year不可再用复数形式。
6. be afraid of sb. / sth. 意为\"害怕\",后面可接\"人\"或\"物\"。be afraid of doing sth.和be afraid + 动词不定式都表示\"害怕做某事\"。be afraid + that从句,表示\"恐怕;担心\",常表示带有歉意的回绝或告知不好的消息, that常省略。例如:
I\'m afraid (that) it will rain tonight.
7. because of是复合介词,意思是\"因为;由于\",后面可接名词或代词。例如:
The football match was put off because of the rain.
because是连词,引导原因状语从句,后面跟句子。例如:
I went home because I was tired.
