Do you like to study in the living-room? I dont think it is a good place because there is often much noise. You had better study in a quiet place, like your bedroom. A quiet place will help you only think about one thing, and you will learn better. Before you begin to study, do not forget to make your desk very clean. A good desk? Light is necessary, too. You are feeling tired easily if there is not enough (足够的) light.21 .

You might want to drink it the next morning. But have you ever wondered if it is still safe to drink?“If you have clean water in a clean glass, youre fine to drink it for a day or two,” Kellogg Schwab from the Johns Hopkins University Water Institute in the US told Time.But you may find that it tastes strange. Thats because after about 12 hours, the carbon dioxide in the air reacts with the water in your glass, slightly lowering its pH level.Also, there might be more microorganisms in your water if you leave it out overnight. Microorganisms grow more quickly at room temperature. These microorganisms can stick to your glass. They can make you get sick more easily. But as long as you clean your glasses very often, this will not be a problem.In countries like the US and UK, people often drink water directly from the tap . This is OK however, tap water cannot be stored for a long time. Most experts say that tap water has a shelf life of six months, according to Zane Satterfield from West Virginia University, US. After six months, there is less chlorine in the water and bacteria start to grow. Youd better not drink the water otherwise you may get sick.What about plastic water bottles? Schwab said people should be careful with them. If you leave a bottle of water under the sun or in a car for a long period of time, the plastic produces a chemical called BPA. This chemical can cause heart disease and cancer.26 . According to the passage,the water in the glass tastes strange after about_.A12 hoursB2 hoursCa day and a nightDtwo days27 . Why does the water taste strange after a night?ABecause there is less chlorine in the water.BBecause the glasses are dirty after a night.CBecause the plastic produces a chemical called BPADBecause the carbon dioxide in the air reacts with the water , lowering its pH level.28 .

They thought humans were the only thinking animals.Now more scientists are studying this subject. But its very hard to prove things that no one can see or measure. So some scientists decided to take a look at brains.Is bigger brain better? No. Cow brains are bigger than dog brains, but that doesnt make cows smarter than dogs. And squirrels (松鼠) have some of the biggest brains of all for their body size. But squirrels arent even close to being the smartest animals in the world. So the size of a brain may give some clues (线索) about brain power, but it doesnt prove anything.Other scientists study thinking by watching how animals solve problems, who watch animals in the wild or set up thinking tests in a lab. For example, a scientist might put some food just out of an animals reach. One kind of animal may grab (夺取) a stick and use it to slide the food over. Another kind might not be able to figure out a way to get the food. Some scientists think animals that have lots of problems to solve must be smarter than animals with simple lives. Scientists also study certain kinds of behaviour for clues about thinking. They watch for three things: whether animals use tools, how they act with each other, and how they commun
