protect from
supposed to each othe

keep .from .polluting

protect the environment,必须加the

protect from
supposed to each othe

答案:B.to protectin
make a contribution to sth/doing sth.对.作贡献.
这是固定的句型,注意那个"to"是介词而不是不定式,介词后面要加动词或动名词.

第一题B
AC在句子里面没有适当的结构.这句话其实是一个形式主语结构,也就是说to protect xxx才是主语,这样看protect和protects都没有名词属性是不行的.to 表示目的,总得来说,it's our responsibility/duty/job这种的形式主语固定都是用to do 的
第二题B
先从第二空看,just now是一个一般过去时的关键词（这是一个具体的时间点,而这个事件发生在那个时间点上,但现在完成式是延续的,不能确定到某个过去时间点上）,放弃AD
既然都说了是一般过去时,那么C是将来时,说不通,选B
第三题D
首先确立了时间是last summer,那么一定是过去式,AC排除
so do sb是指某人也做了这个事情,而so sb/sth do 是肯定强调,比如
-It's a wonderful film
-So it is ←这句就是说它确实是这样的,强调而已
这个人是说我也去游了,那么就选B
选B
although是转折关系,就算是从关系上来说CD都不对,更何况though although后面的分句是不能跟连接词的,也就是说but,and都不能跟（例外的是yet,可以跟yet）
所以选B

everyone shoule try his best to protect the environment.

A
make a contribution to doing sth

to ,Orientational Prepositions方位介词
make a contribution to sth/doing sth.

Everybody knows waste paper and used coke cans are discarded everywhere.You might have seen plastic bags flying in the sky and getting caught in the trees when the wind blows or maybe you have seen old cans floating in the rivers and polluting the water.Our environment is the place in which we live,but it is being ruined by us.
There is a story about house and trees.It is said that a man's house was surrounded by a lot of trees.Though the wind was strong,the man could have a good rest under the trees.How comfortable the life was.One day,the man wanted to enlarge his house,so he cut down all the trees.Then the autumn came without the protection.the strong wind blew the roof of the house into the sky.The house was gone with the wind.What a pity!But that is the price people have to pay for destroying in the ecology balance.People shouldn't be short-sighted,Protecting the environment is everyone's task.
As you know,there are four kinds of pollution.They are air pollution,water pollution,waste pollution and noise pollution.But what can we do to solve the pollution?I think,firstly,we can make cars that don't pollute the environment.We can ask companies to use modern clean technology.In some big cities,we can limit the number of cars.Secondly,we can try to use less water and make sure that we don't pollute the water.We can tell factories that they are not allowed to pour waste water into the lakes and rivers.Thirdly,we shouldn't throw rubbish in parks and cities.We can pick up rubbish if we see it.We can put more rubbish bins in parks and cities.Fourthly,we can live far away from the noise and make the laws to limit the noise.
In order to make our environment clean,let's join our hands together to make the world better.
