It can refer to past periods of warming, such as the one occurred about,000 years ago, towards the end of the last Ice Age, but it is usually used to mean the change in the climate that it is thought likely will occur as a result of the greenhouse effect, as explained below. The present average surface temperature of the Earth is about C (9 F) and this varies by a few tenths of a degree each year. Over longer periods of time, the Earth's surface has been both cooler (perhaps about C or C (between F and F) during the Ice Ages, or glacials) and warmer (perhaps about 6 C (6 F) during some periods between the Ice Ages- the interglacials). Over the past 00 years or so, the average surface temperature has increased by about 0. C ( F). The most probable explanation for the present global warming is that it is the result of increasing concentrations in the atmosphere of greenhouse gases - such as carbon dioxide, methane, and chlorofluorocarbons - which allow energy from the Sun to reach the Earth, but prevent some of it from escaping back into space. These gases have been steadily building up for over 00 years, largely as a result of mankind's use of fossil fuels, such as coal and petroleum, to provide energy. Since we will almost certainly continue to rely on fossil fuels as our main source of energy for many years to come, and since the Earth's population is expected to have doubled by the year 00, the concentrations of greenhouse gases will continue to rise throughout the next century. It is estimated that global warming will increase the average surface temperature of the Earth by between C and C ( F and F) by the year What is the best definition for global warming? ) A collection of different climates around the world. ) The change in the climate that happens as the Earth grows older. ) An increase in the average surface temperature of the Earth over a period of time. ) The past periods of warming about,000 years ago, towards the end of the last Ice Age. 9

Groups may form for a wide variety of purposes, some informal, such as a gathering of friends, others formal, such as a committee. Formal groups often develop strict rules about procedure. A committee may appoint a chairperson, a secretary, and a treasurer. The group will have rules about how a meeting is to be conducted. After the meeting a formal record of what happened will be made and distributed to members. Some groups of this sort, such as a commercial company, will have an order in which communication conforms to rules, a person may be given orders by someone above, and then pass orders down to someone below. People will communicate with those above them in the grading, those below them, and those on the same level as themselves. Even in an informal group, communication is always more complicated than it is between two individuals. Some people feel very nervous when they are in a group; they might either keep quiet and say nothing at all, or else they may start speaking and never want to stop. To work well in a group, you have to learn to listen as well as to speak, and you must be prepared to change your mind, or to agree to cooperate with other people present. No group works well if its members are selfish and stubborn. 96- What is the best title for the passage? ) Secrets of Social Life ) Formal and Informal Groups ) Communication of Dominant Species ) Human Relations in Groups 97- The word "it" in paragraph refers to. ) formal group ) individual ) communication ) informal group 98- The word "strict" in paragraph is closest in meaning to. ) correct ) exact ) perfect ) private 99- What is the main idea of the second paragraph? ) People should learn how to hold a meeting. ) In companies, orders are given to people in a strict way. ) In formal groups, people only communicate with those above them. ) Members of formal groups cooperate with each other according to certain rules. 00- It can be understood from the passage that to communicate well in a group, you need to. ) listen better than you speak ) be open to ideas different from yours ) learn how to make all members think like you ) agree with all the selfish and stubborn members 0
