人教版初二英语下册知识点1
1.How often do you exercise?你(你们)多久锻炼一次身体?
How often +助动词do(does或did) +主语+ do sth.?疑问词how often是问频率(多久一次),(在这里助动词do(does或did)是起帮助构成疑问的作用)与一般现在时或一般过去时连用，回答一般是用表示频率的副词，如：once, twice, three times…, sometimes, often, quite, often, never, every day, once a week , twice a month , three times a month , three or four times a month等。
2“What do you usually do on weekends?” “ I usually play soccer.”
“周末你通常做什么?”“我通常踢足球。”
第一个do为助动词,在这起帮助构成疑问的作用;而第二个do则是实义动词。
3. “What’s your favorite program?” “It’s Animal World.”
“你最喜欢什么节目?”“动物世界。”
4. As for homework , most students do homework every day .
as for...意思是“至于;关于”，常用于句首作状语，其后跟名词、代词或动词的-ing形式(即动名词)。如：
5. Mom wants me to get up at 6:00 and play ping-pong with her .
want to do sth.意思是“想要做某事”;
want sb. to do sth.意思是“想要某人做某事”。如：
有很多动词后面用这种结构做动词的复合宾语
ask sb. to do sth.叫某人做某事
tell sb. to do sth.告诉某人去做某事
help sb. (to) do sth.帮助某人做某事
6. She says it’s good for my health.
be good for...表示“对……有益(有好处)”;其反义为：be bad for...(这里for是介词，后跟名词、代词或动名词)
7. How many hours do you sleep every night?
8. I exercise every day , usually when I come home from school .
9. My eating habits are pretty good .这里pretty相当于very 。
10.I try to eat a lot of vegetables , usually ten to eleven times a week .

help sb.(to) do sth.帮助某人做某事
12. Good food and exercise help me to study better.

13.Is her lifestyle the same as yours or different?=Is her lifestyle the same as your lifestyle or is her lifestyle different from yours?
be the same as … / be different from …
14. What sports do you play ?
15. A lot of vegetables help you to keep in good health .
keep in good health = keep healthy = stay healthy
17. That sounds interesting.
这是“主语+系动词+表语”结构的简单句。sound(听起来)，look(看起来)，smell(闻起来)，taste(尝起来)，feel(觉得)，seem(好象)，grow(变得),get(变得)等词在英语中可用作系动词，后跟形容词作表语。
