题目内容

2.Look!We can't cross the bridge.It_______ by some workers.(  )
A.repairsB.is repaired
C.is being repairedD.is repairing

分析 看!我们不能过桥.一些工人正在修桥呢.

解答 答案:C  根据We can't cross the bridge. 可知It_______ by some workers.这句话的主语是It,是动作的承受者,它和动词repair构成被动关系,所以应该用被动语态.根据Look!可知应该用现在进行时态,现在进行时态的被动语态的构成:be+being+过去分词.主语it,所以应该是is being repaired,故选:C.

点评 本题主要考查被动语态,当句子的主语是动作的承受者时,应该用被动语态,本题考查的是现在进行时态的被动语态.一定注意其构成形式,现在进行时态的被动语态的构成:e+being+过去分词.

Saving water is an important part of going green. As water becomes less and polluted more, conservation(保护)becomes more and more important. The less water you use, the less wastewater will end up in our rivers and lakes. Wasting water means that more water needs to be treated and cleaned, a process that requires quite a lot of energy.

As it is said above, cutting down on water usage is one of the most important things you can do for your local environment and the planet as a whole. That is why more green households are going blue: cutting down their water footprint by conserving and harvesting(收获)water.

It may seem like a big concept, but going blue starts with small changes that everyone can make. Something as simple as turning off the tap while you brush your teeth can save a lot of water. Wash your fruit and vegetables in a bowl rather than under a tap to save even more. Make sure that the taps are fully turned off every time you step away from the sink or the shower - all those little drips can add up to a lot of water waste.

Another way of reducing your water footprint is reducing your dependence on the main water supply. Rainwater harvesting can meet a lot of your home's water needs. Many of us already practice rainwater harvesting in a small way. Collecting water from your gutters(檐沟)is a great way to keep your garden green without running the sprinkler(洒水器).

17.Information is received into our brain by attention,and its quality determines (决定) how well it will be processed,saved and used afterwards.
