八年级上册英语第二单元知识点2重点句子:
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),(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。
Eg1)——How often do you go to the factory?
——Twice a week.你们多久到工厂去一次?每星期两次。
Eg2)——How often does he go shopping?
——He goes shopping once a month.
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。”
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.
Eg2)What does she usually do on weekends? She sometimes go hiking.
3.——“What’s your favorite program?”
——“It’s Animal World.”“你最喜欢什么节目?”“动物世界。”

help sb. (to) do sth. 帮助某人做某事
6. She says it’s good for my health.

be good with“和…相处的好”;
如:I’m good at playing football.
Are you good at children?
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开头的特殊疑问句使用的仍是陈述语序。
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?

2)表示“……几次”的表达方法是:
once a day/ a week/ a month/ a year
twice a day/ a week/ a month/ a year
与different
解析:1)same指“相同的”,前面通常要有一个定冠词the,但是如果same前面已经有this,those等词,不能再与the连用了。
例:We are in the same class.我们在同一个班级。
