    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 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 (檐沟) is a great way to keep your garden green without running the sprinkler (洒水器).

（1）、The underlined word “green” means ______ in this passage.

A、嫉妒 B、环保 C、未成熟的 D、健康的

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

（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

（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

     People use money to buy food, books and hundreds of other things they need. When they work, they usually get paid in money.
Most of the money used today is made of metal or paper. But in the time long ago, people used to use all kinds of things as money. One of the first kinds of money was shells.
    In China, cloth and knives were used as money. Elephant tusks(牙), monkey tail and salt were used in some parts of the world. Rice was also a kind of money used by the people in some islands. Some animals were used as money, too.
     The first copper coins were made in China. They were round and had a square hole in the center. Different countries have used different metals for their money. Later, some countries began to make coins of gold and silver(银). But gold and silver were heavy to carry when people needed a lot of coins to buy something expensive. The Chinese were the first to use paper money. The first paper money looked more like a note from one person to another than the paper money used today.
     Money has had an interesting story from the days of shell money till today.

Computers can injure you. Most other injuries happen suddenly. For example, if you fall off a bike and break your arms, it happens very quickly. But computer injuries slowly.
You probably know how to ride a bike safely. Now learn to use a computer safely.
Your eyes
Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be at least 50 centimeters from the screen. Remember to look away from it sometimes. This gives your eyes a rest.
When you use a computer, the window should be on your left or your right. If it is behind you, the light will reflect on (反射) the screen. If the window is in front of you, the sun and the screen will both shine into your eyes.
Your hands and wrists (手腕)
Hand and wrist injuries can happen because the hands and wrists are moved in the same way hundreds of times. If you use a keyboard for a long time, follow these three rules: 1) Rest your wrists on something. 2) Keep your elbows at the same height as the keyboard. 3) Stop something and exercise your hands, wrists and fingers in a different way.
Your back
Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your back or your neck. So you should sit with your back straight. The top part of the screen should all be in front of your eyes. Your forearms, wrists, hands and the upper part of your legs should all be parallel (平行) to the floor. If you are sitting for a long time, get up every 30 minutes and exercise your arms, legs and necks.
Enjoy your computer, but use it safely.

Look at the centre circles of Diagram (图)A and Diagram B. Which of the centre circles looks larger? In fact, they are exactly the same size.
Then look at the picture on the right. What do you see? A vase? Or two faces？Does the picture change quickly from one to the other again and again? Maybe or maybe not, but you can never see them at the same time.

“What's happening? Is something wrong with my eyes?” You may wonder at what you see. Don't worry. Here is how it goes:
When we look at things, our eyes send messages to our brains and then our brains interpret（解读）the information. However, sometimes our brains interpret the received information in a wrong way. It seems that our eyes are playing a joke on us. This often happens and we call it “visual illusion(视觉错误)”.
Movie makers often make use of visual illusions. They make the objects around actors much smaller or bigger than usual. This makes us believe that the actors are much larger or smaller than they usually are. The movies Jurassic Parkand Honey I shrunk the kids just make use of visual illusions.

   Imagine one day the water taps (水龙头) in your house stop running. You have to pay a lot of money to buy water from shops. And still there isn't enough water for everyone. Your mother has to save the family's shower water to use for washing clothes. Would you be able to stand that kind of life?
   Probably not. But that is what kids in Yemen (也门) are experiencing (经历). According to a report, the capital, Sana, will run out of drinking water as early as 2025.
   Because of the water shortage (短缺), the Yemen government often cuts the water supply (供应). Hannan, an 18-year-girl, tells the Teens, “In a good week we'll have a water supply all week. But then the next week there will be water only for a day or two.”
   Hannan says only rich people have enough water to use. They can buy water from the shops or from the water trucks. Private (私人的) companies own the trucks, They travel around the city every day to sell water-- at very high prices.
   “A lot of people can't pay for it,” she says.
   The government is thinking of making use of seawater. But it will cost a lot and it may not happen soon enough to help the people of Yemen.

The human brain weighs about 1.4 kilograms, but it can, hold much more information than most computers. However, there is another difference between humans and computers. Computers don't forget information they are given, but humans often do. No one remembers everything, and luckily we don't usually have to. But everyone can improve their memory if they want to. Here are some suggestions.
◆Try to use new information immediately*. For example, if you meet someone who says "Hi! I'm Carlos," don't just say "Hello." Repeat the person's name. Say "________"
◆Break a big number into smaller parts. For example, it's hard to memorize 109244153. But if you break it into three parts--109/244/153—it becomes easier.
◆Write out what you need to remember over and over again. This will help you keep it in mind longer, especially for memorizing formulas * or facts.
◆Always review information. If you bring what you've learned back to your mind, they become easier to remember. For example, before you go to sleep, it's a good idea to review the new things you learned that clay.
◆Discuss with a friend. It is always easier to remember things through discussions. You can have a discussion about what's right and what's wrong, and it will lead to the right answer.
◆Never tell yourself that you have a bad memory. You can always do something to help improve your memory. And everyone's memory gets better if they use it often enough.
All of the suggestions are helpful. If you follow them, you are certain to improve your memory.

阅读下列短文,从每小题所给的A、B、C、D四个选项中选出一个最佳选项。

You know how much your telephone has changed over the past 10 years? Your car will change even more than that in the next 10 years.

One of the biggest changes is that cars will drive themselves. Some day you may not need to drive a car. You will just tell the car where you want to go and it will drive itself.

Google

The American company Google has been working on a self-driving automobile for years. These cars are already on the roads in the United States, mainly in California.

Google cars are truly self-driving. These cars have no steering wheels(方向盘) or pedals(刹车踏板).

Last week, police ordered one of Google's cars to stop for driving too slowly on a public road. The car was not against any law, so no one was punished. But police did speak to the operators of the vehicle(车辆).

According to Google, its self-driving cars have been driven nearly 2 million kilometers. That is equal to the distance the average person drives in 90 years.

So far, no Google self-driving car has gotten a traffic ticket. Some of them have been in accidents when other cars hit them.

Tesla

Another American company, Tesla, added an “Autopilot(自动驾驶仪)” feature to its cars last month. Tesla put the feature, a computer software program, in cars that were built after September 2014.

With the Autopilot turned on, the vehicle drives itself. The car will speed up, slow down, brake and steer by itself.

You can take over driving any time by turning the steering wheel or touching a pedal. Your car will slow down if the vehicle in front of you gets closer. It will turn at bends and change lanes if you use the turn signal.

Tesla Autopilot takes over driving at speeds over 29 kilometers per hour when you press a button twice. Autopilot is made for cross-country driving. It keeps you in the lane and helps you avoid hitting other cars.

Other Self-Driving Cars and Buses

Other companies such as Mercedes-Benz, Audi, BMW, Volvo and Toyota are working on self-driving cars. Another company called BestMile is also working on self-driving buses in Switzerland. The buses can hold up to nine people and will be tested for two years.
