Read the article and select the best answer. Article: Do animals have a culture? What do we mean by "culture"? Lately social scientists have begun to ask if culture is found just in humans, or if some animals have a culture too. When we speak of culture, we mean a way of life a group of people have in common. Culture includes the beliefs and attitudes we learn. It is the patterns of behavior that help people to live together. It is also the patterns of behavior that make one group of people different from another group. Our culture lets us make up for having lost out strength, claws, long teeth, and other defenses. Instead we use tools, cooperate with one another, and communicate with language. But these aspects of human behavior, or "culture", can also be found in the lives of certain animals. Animals can make tools, for example. We used to think that the ability to use tools was the dividing line between human beings and other animals. Lately, however, we have found that this is not the case. Chimpanzees can not only use tools but actually make tools themselves. Animals can also share knowledge with each other and use their own language to communicate. So it may be important for us to know that the line dividing us from animals is not as clear as we used to think. Question: When we talk about "culture", we mean _ . Options: A: book language of behavior we learn B: the patterns of behavior we learn C: traditional ideas D: people's habits

Foods from plants grown in this way are called genetically modified foods ,or GM foods. By changing the genetic material of a plant,it is possible to make new plants. They make plants which are strong against plant diseases. They can also help in our diseases:a kind of rice is being prepared,for example,which stops people from becoming blind.Rich countries produce GM foods because they are easy to grow and they bring in more money.Poor countries are interested in them because they help produce more food. GM plants are not natural.No one knows how good or bad they are.Making GM foods is only one way of feeding people in 2050.But there are strong feelings against them,because they are unnatural. They may feed people,then hurt them or their children later.But both rich and poor countries are very interested in their use,and they are not going to die.In 2050 we may think differently about them.

(Q).
Read the article and select the best answer. Article: Antifreeze is a liquid that is added to water to keep it from freezing. When water freezes and turns to ice,it expands .The force of water expanding is so great that it will break the hardest metal.Water is used in car engines to keep them cool while they run,and if this water is allowed to freeze in winter it can break the iron block of the engine.That is why antifreeze is necessary. Water freezes at 0degC;the usual kind of antifreeze will not freeze until the temperature is-40degC.A mixture of five parts of water and four parts of antifreeze will prevent freezing at-18degC;four parts of water and five parts of antifreeze reduce this to -22degC. Alcohol is a kind of good antifreeze,but when the air is running it becomes hot and the alcohol boils away,so it must be changed very often.Most people use antifreeze that does not boil away when the engine is running.There are several chemicals that do this.One of the most popular is called ethylene glycol. Question: We use antifreeze in order to _ . Options: A: keep alcohol in water B: stop ice from becoming water C: make the freezing point of water lower D: raise the freezing point of water
