Question: Article: The laptop is a machine which can be a mobile office;it can be used to entertain us and people can play computer games on them.One machine can perform many tasks at the same time.As technology grows,the size of the new laptop machines is _ .Now laptops are lighter,have smaller screen sizes,and perform better.Smaller screen laptops,which are more convenient to take along with,have been specially designed for professionals.Huge display screen laptops are still used by graphic designers and those who like playing computer games. Laptops are advanced machines,and they can be very expensive.When we spend much money on something,we should take good care of it.I know some people who buy a new laptop every year.The reason they do this is that the old one either is broken or has some problems which cannot be fixed.Common problems are the breaking of the screen,the breaking of joints of the laptop,display problems,and keyboard problems. Different problems will always come up with machines,and they cannot be avoided .Old machines will always have to be replaced by new ones.However,if we are more careful and handle our laptops with care,they will last for a longer period of time,and they will perform better.This is not a hard thing to do,but it will greatly increase the life and performance of laptops.
Question: We infer that graphic designers still use huge display screen laptops most probably because _ .
Options: (A) huge display screen laptops are very cheap (B) small display screen laptops are not on sale yet (C) they can see their drawings more clearly (D) they also want to play computer games

Answer: C

Question: Article: Humans and many other mammals have unusually efficient internal temperature regulating systems that automatically maintain stable core body temperatures in cold winters and warm summers. In addition, people have developed cultural patterns and technologies that help them adjust to extremes of temperature and humidity . In very cold climates, there is a constant danger of developing hypothermia , which is a life threatening drop in core body temperature to below normal levels. The normal temperature for humans is about 37.0degC. However, differences in persons and even the time of day can cause it to be as much as 6degC higher or lower in healthy individuals. It is also normal for core body temperature to be lower in elderly people. Hypothermia begins to occur when the core body temperature drops to 34.4degC. Below 29.4degC, the body cools more rapidly because its natural temperature regulating system usually fails. The rapid decline in core body temperature is likely to result in death. However, there have been rare cases in which people have been saved after their temperatures had dropped to 13.9-15.6degC. This happened in 1999 to a Swedish woman who was trapped under an ice sheet in freezing water for 80 minutes. She was found unconscious, not breathing, and her heart had stopped beating, yet she was eventually saved despite the fact that her temperature had dropped to 13.7degC. In extremely hot climates or as a result of uncontrollable infections, core body temperatures can rise to equally dangerous levels. This is hyperthermia. Life threatening hyperthermia typically starts in humans when their temperatures rise to 40.6-41.7degC. Only a few days at this extraordinarily high temperature level is likely to result in the worsening of internal organs and death.
Question: Why can humans keep stable body temperatures in different seasons?
Options: (A) Because their bodies are unusually efficient. (B) Because they experience different climates. (C) Because they can adjust to cultural patterns and technologies. (D) Because they have internal temperature regulating systems.

Answer: D

Question: Article: There is growing concern about food insecurity in the developing world. Rising food prices, weather emergencies and political problems are deepening the struggle for families in many countries. Three UN agencies have published a report recently, saying high prices are likely to continue. Gregory Barrow, who is with the World Food Program in Rome, says, "If you look at the places where the World Food Program works, particularly in developing countries, you see people who might be spending more than 60 percent of their salary in purchasing food for their families." East Africa is suffering its worst drought in years. In Kenya, at least three and a half million people are going hungry, mostly in the north. Yet food is going to waste in central Kenya. Now, farmers there want the government to buy their food and give it to those in need. Farmers say bad roads and lack of transportation make it difficult for them to get their produce to the market. Mr. Barrow says, "It needs the government to make some arrangements such as providing transport. They can buy it at a good price, then give it to those people instead of asking for food from overseas, which is very bad. When we are throwing away food, _ are asking for food from overseas." Economists say that imports reduce local food prices, decrease productivity and increase the dependency on other countries. Farmers in Kenya hope the government can pay higher prices for their crops so that they can feed more Kenyans.
Question: What is the best title for this passage?
Options: (A) Kenya Imports Food from Abroad (B) A World Food Program in Rome. (C) The Poor Suffer from High Food Prices. (D) A Report Published by Three UN Agencies.
