1. It's too many cars on the road.
There are too many cars on the road.
（there be 句型，表示有…；It's 直接跟名词，it's a car；或者接形容词，it's beautiful）
2. Let's taking a plane to Harbin.
Let's take a plane to Harbin.
（let's 是let us 的缩写，let sb do sth，所以只能用take）
3. In the city you can by bike go to work.
In the city you can go to work by bike.
（英语语序表达习惯，遵循先说主谓宾you can go to work的原则，方式状语by bike 放在最后）
4. If there is traffic I like to by subway.
If there is traffic I like to go by subway.
If there is traffic I like to take the subway.
(to 不能跟by都是两个介词，不能一起使用，乘地铁：by subway, take the subway)
5. In the morning the bus very crowded.
In the morning the bus is very crowded.
(原句the bus后面缺少谓语is)
6. Sometimes I like drive.
Sometimes I like driving / to drive.
(like 是介词，不能加动词原形，可以用:like doing sth.表示一直喜欢；like to do sth.表示愿意做，倾向于…)
7. The bus is very slowly.
The bus is very slow.
（is 后面+形容词 slow，slowly是副词，用在动词后面，比如，he walks slowly）
8. If I have not enough time, I will take the subway.
If I don’t have enough time, I will take the subway.
(不能用not+enough表示“不够”，习惯用法：don't/doesn't have/has enough…)
9. Subway is very fast.
The subway is very fast.
(地铁很快，这里通指地铁这一类，名词前要加上the，如某一类人：老人，the old)
10. I think take the train is expensive.
I think taking the train is expensive.
（乘地铁很贵，这里“乘地铁”是主语，动词短语做主语一定要加ing，所以用taking）
