重点句型
—How do you usually come to school?
—I usually come to school by subway.
—How often do you go to the library?
—Once/Twice/Three times a week/Very often/Every day/Sedom
重点详解
1.I always come to school by bus.
by+交通工具名称，表示使用某种交通方式，中间不加限定词，如果交通工具前有a, the, my 等限定词，就不能用by,而是用in 或是on.
on the train=by train on his bike=by bike in my car=by car.
巧辩异同on foot 与walk on foot “走路”，是介词短语，不能作谓语，只作方式状语，位于句末。walk “走路”,是动词，可以作谓语。
go to…on foot= walk to I often go to school on foot. =I often walk to school. 同样，go to….by bike = ride a bike to go to…. by car = drive a car to go to … by plane = fly to go to… by bus = take a bus to 2 .Come on! It’s time for class. come on “快点，加油，来吧”。It’s time for sth. “该做某事了”，与It’s time to do sth.意思一样。
3 .look的短语look the same看起来一样look like看起来像……look for寻找look after 照顾
4 .do my homework at school 在学校做作业
do one’s homework 做家庭作业（注意：one’s 要随主语的变化而变化，常用形容词性物主代词my, your, their, our, his, her 等）。
5 we want to know about the school life of American students. know about “了解，知道关于”
6 巧辩异同a few与few a few “一些”，few“很少，几乎没有”，修饰可数名词。 a little与little a little“一些”，little“很少，几乎没有”，修饰不可数名词。
7 They often play basketball or soccer, go swimming and so on. go swimming 去游泳
and so on “等等”，表示还有很多。
拓展go+v.-ing 表示去做某事，类似的有：

8 How often do you go to the library?
how often“多久一次”，问频率。答语常用频度副词never, al-ways,often等或单位时间内的次数
