解析試題分析:英語中一般用基數詞表示分數的分子,用序數詞表示分數的分母。當分子是一時,分數的分母用單數形式,在表示分數時,當分數的分子大于一時,分數的分母要用復數形式。由分數修飾的主語后面謂語動詞的數,和被修飾主語的單復數保持一致。根據分析可知選項BCD結構有誤,故選A。
考點:分數表達
點評:英語分數的表達規則比較固定,學習中應牢記這些基本規則。需注意的是,由分數修飾的主語后面謂語動詞的數,和被修飾主語的單復數保持一致。

科目:初中英語 來源:2013屆江蘇省南京市白下區中考二模英語卷(帶解析) 題型:閱讀理解

Saving water is an important part of going green. As water becomes less and polluted more, conservation (保護) 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 (收獲) 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 fruits 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 (檐溝) is a great way to keep your garden green without running the sprinkler (灑水器).
【小題1】The underlined word “green” means ______ in this passage.

A.嫉妒B.環保C.未成熟的D.健康的
【小題2】According to the passage, which is NOT the reason that people should save water?
A.Treating wastewater needs much energy.
B.The water on the earth is becoming less and less.
C.The water on the earth is becoming polluted more.
D.Rainwater harvesting can meet a lot of your home’s water needs.
【小題3】According to the passage, all of these can be used to save water except ______.
A.washing fruit and vegetables under a tap
B.using a bowl to wash your fruit and vegetables
C.making sure taps are fully turned off all the time
D.turning off the tap every time after brushing your teeth
【小題4】Which of the following is the best title of this passage?
A.Save Water by Turning off the Tap
B.How to Treat and Clean Wastewater
C.Keep Your Garden Green with Rainwater
D.Save Water Starting with Small Changes
【小題5】From the passage, we can know that_____.
A.we can get enough water by harvesting
B.most people pay no attention to saving water
C.we can practice rainwater harvesting in a small way
D.harvesting water is more necessary than conserving it

Many of us don’t pay much attention to the importance of eye care. It is said that if you take care of your body, then you can surely be healthy. That is why our eyes should be given a lot of care. Natural eye care should be put in a number one place.

There are several causes leading to poor eyesight like not enough food, genes(基因) and aging(老化). Televisions, computers and reading are also the causes of having poor eyesight. If you happen to work in front of the computer, it is best to have a rest after working for a while. Something dirty can cause redness and they will make you uncomfortable. It is bad for your eyes, too. If this happens, the best way is to clean your eyes by using cold water. You must also try your best to protect your eyes from harmful things. For example, sunglasses are not just for fashion but they can also serve as a great way to protect your eye-sight from UV rays.

Eating healthy foods will do good to your eyesight. Remember that vitamin A, C and E are good for eyes. Try to eat food groups that have these vitamins. And you should do eye exercises because exercise protects your eyesight, too. If a person exercises regularly(定期的) and eats the right kind of food, his eyes will stay in good condition(狀況) for a long time.

All above are natural ways of eye care that help us keep healthy eyes. Being happy all the time can be helpful to a person’s eyesight, too. In a word, eye care is very important, no matter how old a person is.
