重点句子：

do you usually do on weekends -----I often go to the movies.

(1) on weekends/on the weekend在周末 (2) go to the movies 去看电影

2. hardly ever 几乎从不 hardly ever 相当于 hardly, ever起强调作用。

hardly 为副词，意为“几乎不没有）”，相当于almost not，本身具有否定含义，不能再使用其他否定词。

3. ----How often do you watch TV ----Twice a week.

(1) how often 意为“多久一次，多长时间一次”，用来提问频率。

(2) twice a week 一周两次

拓展: 一次 once 两次 twice 三次或三次以上基数词+ times three times four times

4. What's your favorite program = What program do you like best 你最喜欢的节目是什么

5. How come怎么回事怎么会表示某件事情很奇怪，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 开头的特殊疑问句使用的仍是陈述语序。

How come you didn't tell me about it = Why you didn't tell me about it

6. I go to the movies maybe once a month. 我也许一个月去看一次电影。

maybe 副词，意为“或许，大概，可能”，常位于句首。 . Maybe he knows the way to the park.

辨析：maybe 与 may be maybe副词，作状语，意为“或许，大概，可能”，常位于句首。

may be 属于“情态动词+be 动词”结构，意为“可能是”。

(1) The baby is crying. _______________she is hungry. (2) The woman__________________a teacher .
