Earth Day is April 22.But on all other days,we must also remember it.The water we use is the most important natural resource on the earth. Water covers 70% of the earth's surface .But most of that is sea water.We can't use it for many things.Fresh water covers only 1% of the earth's surface. You probably feel lucky that your life isn't as hard as Napoga's.But that doesn't mean you don't have to worry about water.We all face serious water problems.One of them is water pollution.All kinds of things from cars,factories,farms and homes make our rivers,lakes,and oceans dirty.Polluted water is very bad for people to drink.And dirty water is bad for fish,too.Now,34% of all kinds of fish are dying out. How do cars and factories make our water dirty?First,they pollute the air.Then,when it rains,the rain water comes down and makes our drinking water dirty.Dirty rain,called acid rain ,is also bad for plants,animals and buildings. Scientists say that in 30 years,more than half of the people in the world won't have enough clean water.We have to learn how to save more water for ourselves and our children.Here is some advice for saving water: * Turn off the water while you brush your teeth.You can save as much as 450 liters each month. * Leaky taps waste a lot of water.Fix them right away! * You can easily cut your 10-minute showers in half--and you'll be just as clean. * When you wash dishes,don't let the water run. * Only wash clothes when you have a lot to wash.If your washing machine isn't full,you're wasting water!

Write a multi-choice question for the following article, with the given choices and answer: Article: French doctors and American scientists have reported doing an operation in which the doctor was outside the operating room. This kind of operation is known as robotic operation. Doctor Marescaux did the operation in an office in New York City last month, while a sixty-eight-year-old woman patient was in a hospital in Strasbourg, France. A doctor in Strasbourg got the patient ready. He placed medical tools and a small video camera in her stomach area. Doctor Marescaux in New York watched the patient on a video screen. Then he used the computer to send messages to the robot machine. The robot moved the tools that cut the woman's gallbladder away. The woman got well soon after the operation and left the hospital two days later. Experts say the main problem with such a robotic operation is based on high-speed telecommunications between the doctor and the robot. Technology must be able to send a doctor's order to a robot to move the tools quickly. Experts also say a successful robotic operation will improve an operation. For example, the robot can make much smaller movements than a person can. A robot machine can turn tools in ways that a doctor's hand cannot. Doctors say such a robotic operation will make possible safer and better operations in the future. They say it will improve doctor training. It will also mean that doctors could do an operation on people in dangerous places far away. And it could mean that people could have operations done by top doctors without having to travel to the city where doctors work. Options: A it can send messages at a high speed B even a top doctor can't do the operation himself C it can make the operation safer and better D operations can be done without any doctors Answer: C it can make the operation safer and better Question:

Answer: We use the robot in the operation because _ .

Write a multi-choice question for the following article, with the given choices and answer: Article: An astronaut's work may sound exciting, but living in space isn't as fun as you think. The website www.space.com lists the disadvantages of living in space. Here are some of them. When astronauts work outside the station during spacewalks, they have to wear special gloves. The gloves are very tight. They can hurt the astronauts' fingernails and even make them fall off. In space, you don't have many choices in what you eat. It's hard to get fresh fruits and vegetables. It is not OK to eat bread because it leaves crumbs . Crumbs could fly around everywhere. In space, it is impossible to have a good shower because water can fly all over the ship and break the machines. Astronauts have to use a special water-shooting gun and a washcloth. Astronauts lose their bone strength quickly during their stay in space. So far, there is no way to solve this problem. They do exercise while they're in space to try to keep their bones strong as long as possible. Perhaps the hardest part of life in space is the feeling of loneliness. Astronauts sometimes have to spend weeks and even months away from Earth. They miss their friends and families. Options: A Washcloth. B The special gloves. C The water-shooting gun. D Crumbs. Answer: B The special gloves. Question:
