Q: Article: If you go to visit London,you will see a lot of buses and cars on the road,you will also see a lot of bikes because more people travel by bike.Why? There are a lot of reasons for this.First,it's very cheap to buy a bike,and riding bikes is quick, too.You often need to wait for a bus for half an hour.When the bus comes,there are so many other buses and cars on the roads so the bus moves very slowly.The underground train is quick but very expensive. I travel to work by bus for about four years.I often arrive at work late and feel tired.Then one day , a friend of mine says, "I go to work by bike,why don't we travel together?""Because my bike's old,"I answer,"and there are so many buses and cars on the road.I feel afraid...""Don't be afraid!"says my friend,"If you follow me and we ride slowly,you will be fine." Two days later I buy a new bike.We go slowly, but we arrive at work quickly. I spend 40 minutes going by bus, but only half an hour by bike! Now I love riding a bike. And I feel healthy. Many people think my idea is good and maybe you'll see more bikes on the road in the future. Many people think in the same way as I do.That's why you see a lot of bikes on the road.Who knows,perhaps in the future we'll have roads for bicycles only.I hope so! Question: Which is NOT mentioned about the good things of riding a bike in the passage? Yes or no, is the answer "we can keep the air clean."?

Question: Article: Dear editor, I live in a beautiful city. Many visitors come to my city every year because there are so many colorful peacocks here. The peacocks mostly live on the grassland of Dongfeng Square. Visitors usually throw food to them, but they don't think about at all whether the food is good or not. Some of the peacocks became ill, and some even died eating the bad food given by visitors. I'm sure most of the visitors who throw food to the peacocks really like the bird, but they don't realize that they may be doing them harm . Visitors should be told that what they have done is harmful to the birds, and this kind of thing must be stopped. Perhaps we can build some small shops beside Dongfeng Square to sell peacock food. For us every person, it is our duty to give more love to these beautiful birds to look after them carefully. Yours, Wang Yang Question: Some peacocks became ill and died because _ . Yes or no, is the answer "they were given some bad food"?
Answer: No

Article: Some days, don't you think, "Wouldn't it be nice if the laundry would just do itself?" Self-cleaning clothes may sound crazy. But Australian researchers have found a way to make something like this possible! A team at RMIT University in Melbourne, Australia, found a way to put special nanostructures into clothing, which can then clean the clothes. When sunlight hits the nanostructures, they break down the dirt and stains that don't belong on your clothes. The nanostructures don't break down the actual clothing because cotton and the other clothing materials are too strong to be broken down. According to CNN, the researchers cover the clothing in a solution made of silver and copper nanostructures. All it takes is 40 minutes of sunlight and your clothes will look as good as new. So if you spill on yourself during lunch, you can step outside for a walk, and it will be clean by the time you go inside. It not only makes your life easier, but it can also be good for the environment. According to the US Department of Energy, the average load of laundry uses about 25 gallons (about 94 liters) of water. Water is a very important resource, so using less of it to wash clothes is better for the environment. But one of the scientists at RMIT University knows more needs to be done. "There's more work to do before we can start throwing out our washing machines," said Dr Rajesh Ramanathan, "but this is a strong foundation ." So what's the next step? Ramanathan wants to either start selling the solution by itself or convincing clothing makers to treat the clothing with the solution while clothes are being made. Question: How do the clothing with the nanostructures get cleaned? Yes or no, is the answer "The dirt and stains are broken down in the sunlight."?
(A).
No
