【基础知识】
一、重点句子解析：
1.How often do you exercise? 你（你们）多久锻炼一次身体？
解析：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)
often, never, every day, once a week , twice a month , three times a month , three or four times a month
Eg)——【人教版八年级英语上册第二单元how,often】
——Twice a week.你们多久到工厂去一次？每星期两次。
2. usually do on
——“ I usually play soccer.”“周末你通常做什么？”“我通常踢足球。”
解析：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。
Eg1)What do you usually do on weekends? I often go to the movies.
3.——“What’s your favorite program?”
——“It’s Animal World.”“你最喜欢什么节目？”“动物世界。”
解析：as for...意思是“至于；关于”，常用于句首作状语
如：As for him，I never want to see him here. 至于他，我永远不希望在这里见到。
解析：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：
ask sb. to do sth. 叫某人做某事
tell sb. to do sth. 告诉某人去做某事
6.well,how about Tuesday?哦，那星期二怎么样啊 ？

辨析：
be good for“对…有益”；

18.How come?怎么回事？
解析：表示某件事很奇怪，有点想不通。可单独使用，也可引导一个问句，相当于疑问词why. 但how come
如：How come you didn’t tell me about it?
=Why didn’t you tell me about it?你怎么不早点告诉我这件事？
【词语辨析.】
1.注意sometimes与几个形似的词的区别。
（1） sometime意为“在某个时候”，“某时”例：Will you come again sometime next week?
（2） some time意为“一段时间”，例：I will stay here for some time.我将在这呆一段时间。
（3）some times“几次，几倍”例：他好几次了。
（4）sometimes 意为“有时”=at times例：He sometimes goes skateboarding on weekends.他有时周末去滑滑板。

例1：What time is it?
例2：I go to the movies three times a week.
注意：
1）“次数”的表达方法：
一次once；两次twice；三次或三次以上用基数词加上times：three times、five times、one hundred times.
2）表示“……几次”的表达方法是：
twice a day/ a week/ a month/ a year
3.same与different
解析：
the same as 与......一样
be different from 与......不同
此外：different译为“不同的”，其后的可数名词应为复数形式。
different的名词形式为difference, 复数形式为differences。
4. hard / hardly
1）hard:
adj. 辛苦的，困难的 例He had a hard (adj.)time in the past.

如good, kind, nice, clever, foolish, right。
如：It's very nice of you to help me. 你来帮助我，你真是太好了。

如easy, hard, difficult, interesting, important, impossible等;

7.across与through区别
across为“横穿”，与“道路”交叉形成“十字”，即：从物体表面经过，如：过河、过桥、过马路。 through为在立体空间中的“穿过”即：从物体内部经过，如：穿过森林、隧道。
