“Let’s”是“Let us”的缩写形式，其后接动词原形（即省去to的动词不定式）。以“Let’s”开头的句子为祈使句。例如：

(1)句中的need作动词，意为“需要”。例如：

need还可作情态动词，常用于否定句。例如：
---Must I finish the work today?---No, you needn’t.
——我必须今天完成这项任务吗？——不必。
(2)a lot of = lots of 意为“许多、大量的”，相当于many或much。例如：

(2) 句中的exercise 作动词，意为“锻炼”。例如：

4.I walk to my bowl many times a day. 我一天跑向我的饭碗好多次。(P58)

6.I want to be a dancer. 我想要当舞蹈家。(P60)

（2）dancer是由动词dance加后缀-er变化而来的。例如：

drive-driver; write-writer;
swim-swimmer; run-runner;
7.It’s easy for me to get tired when I dance. 我跳舞时很容易疲劳。(P60)
（1）该句的句型结构为“It is adj. for sb. to do sth.”意为“做某事对某人来说…”， it为形式主语，真正的主语为动词不定式to do sth.。因此，原句可改写为：To get tired when I dance is easy for me。例如：
It is important for us to read English every day.= To read English every day is important for us.
It’s not easy to learn English well.= To learn English well is not easy.

9.After class, I also like playing computer games and chatting with my friends on the Internet.课后我也喜欢玩电脑游戏和在网上与朋友聊天。（P60）
also是副词，意为“也”，与too同义，但also一般置于行为动词之前、be动词或助动词之后；too一般置于句未。例如：
She is also from America.= She is from America, too.
I also like singing.= I like singing, too.
either也可表示“也”，但通常用于否定句, 一般置于句未。例如：

10.It's time for me to change now. 我现在该改变了。P60）
