What is the sky? Where is it? How high is it? What lies above it? These questions are difficult to answer, aren't they? Is the sky blue? The sky has no colour. We know that there is air around the world. When planes fly, they need air to lift their wings. Planes cannot fly very high because when they go higher, the air gets thinner. If we go up about 1,200 kilometres from the earth, we find there is no air. Perhaps we can answer some of our questions now. The sky is space. In this space there is only the sun, the moon and all the stars. What is the sky? _ . A) It's the clouds B) It's space C) It's air D) It's nothing

The Body Temperature The temperature of your body should be always just the same, no matter whether the weather is hot or cold. That is why the doctor uses his thermometer when your are sick. The body keeps the same temperature all the time ,because it balances the heat it produces and it gives off. It is always burning up food and , producing heat. It can produce heat faster when it needs to give off heat than when it becomes too warm. Let's see how this happen. The heat of your body is given off mainly through the skin. When you are cold, your skin is tight and shows "good flesh". When you get chilly, you must dance around to keep warm or else you will shiver. Then your muscles begin to work, burn up fuel, and produce more heat. It is not pleasant to shiver, so you usually prefer to warm up by exercise, or put on more clothes to keep heat in. When you are warm, the skin is loose and soft. It is so supplied with blood that heat is given off rapidly. If you get too warm, you begin to sweat ,and more body heat is used in evaporating the moisture from your skin. You wear less clothing, too, in warm weather or warm room, so that warm can be given off freely. You feel less like exercising because your body is warm already, and the extra heat produced by exercise makes you uncomfortable. You can see from the way you feel differently in different kinds of weather. In summer, when it is warm, you feel tired and lazy. You do not care to work or play, but enjoy lying and doing nothing. When you get out of doors in winter, the cold air makes you feel lively. You want to play. How does the body keep the same temperature all the time? A) It is always producing heat from food. B) It gives off the heat produced in it. C) It balances the heat it gets and loses. D) It stops producing heat when necessary.

Ques: Twenty-three-year old Rio Safiyanto sells face masks, or coverings, for about 30 cents each in central Jakarta, Indonesia. He makes enough money to buy a cell phone that permits him to visit websites. He says every average person has a cellphone. He likes having one because he can talk to his family when he is away from home. And, he is especially pleased that he can use it to listen to music. It is known as a feature phone . That is because it is cheaper and cannot perform as many actions as more advanced phones like the Apple iPhone. These devices make up the majority of cell phones sold around the world. They have proven more successful in places like Indonesia, where some smartphones cost 700 dollars or more. Although many lower-income users are new to smartphones, they are quickly learning to use the technology. Cell manufacturer Nokia offers a service called Life Tools. For a small monthly payment, the company sends text messages to farmers. The messages tell of weather conditions, crop prices, agricultural news and give other advice. Local businessman Aldi Haryopratomo has developed a way for small store owners to sell things like prepaid cellphone minutes and life insurance through text messages. Ruma is the company that developed the technology. The company is working on a system that will _ people about jobs in their area. At a recent digital technology show in Jakarta, banks offered no-interest financing for credit card purchases. Marina Luthfiani manages a mobile shop in the area. She said almost everyone can buy a smartphone because of competitive financing and credit choices. She says Indonesians like to buy the latest devices. A report last June by Semiocast, a French internet research company, said Jakarta was the world's top tweeting city, ahead of Tokyo and London. Why are feature phones popular in Indonesia? A) It has fewer functions. B) It can be used to enjoy music. C) It is less expensive. D) It is more attractive.

Question: Language is a major problem for the European Union (EU). The agreement or treaty which created the organization that eventually became the EU, the Treaty of Rome, stated that each country's language must be treated equally. The original six countries had only three languages between them: French, German and Dutch/Flemish. However, there are now 15 countries in the EU, with a total of 12 languages. EU documents must be translated into all these languages, and at official meetings the speeches must be translated into all the languages by interpreters. All this translating is very expensive and time-consuming . It is said that nearly half of all employees of the EU are engaged in translating documents and speeches, and nearly half of the EU's administrative costs are spent on this task. In the near future it is probable that several more countries, most of them having their own languages, will join the EU, thus making the situation even worse. The problem is not just cost; there are practical difficulties as well. With 12 languages, there are 132 possible "translation situations" that might be needed. It is often difficult to find people in the right place at the right time who can translate from (for example) Danish into Greek, or Dutch into Portuguese, at a high professional standard. In practice the problem has been made less severe by the use of English in many contacts between EU officials, since almost all of them speak some English. However, any move to reduce the number of official languages (perhaps to four or five) would be a blow to the pride of the smaller Countries. Another commonly suggested solution is to make English the official language for all EU business. However, this is strongly resisted by powerful member countries like France and Germany. According to the writer, the use of English in contacts among EU officials has _ . A) angered the officials who don't speak English B) reduced the number of official languages C) reduced the effect of the problem D) been opposed by powerful member countries
