Read the passage carefully, then choose the correct answer.
Coal, oil, and natural gas supply modern civilization with most of its power. However, not only are supplies of these fuels limited, but they are a major source of pollution. Therefore, it's important to improve, explore and develop such alternative energy sources as nuclear, water, solar and wind power. Each of these alternatives, however, has advantages and disadvantages.
Nuclear power plants efficiently produce large amounts of electricity without polluting the atmosphere; however, they are costly to build and maintain, and they create the difficult problem of what to do with nuclear waste. Hydroelectric power is inexpensive and environmentally safe, but impractical for communities located far from moving water. Wind power is a pollution-free source of renewable energy but it cannot be used in many parts of the world where there is insufficient wind. Solar power is renewable, it does not cause pollution and it does not add the earth's heat load. However, it is difficult to collect and store. Solar power also requires expensive equipment. 
What is the advantage of these alternatives?
A.They are environmentally friendly energy sources. 
B.They are non-renewable forms of energy.
C.They are all very practical.
D.They are inexpensive to exploit.

The American education system requires that students complete 12 years of  primary and secondary education prior to attending university or college. This may be accomplished either at public or government-operated schools, or at private schools. These 12 years of schooling or their equivalent may also be completed outside the USA, thus giving foreign students the opportunity to pursue the benefits of the American education system and obtain a quality American education. Perhaps one of the most impressive facts is that a large number of presidents, prime ministers and leaders from other countries have experienced the American education system and graduated from a university or school in the USA. In many fields and industries, the American education system offers the most cutting-edge, sought-after programs at the world's best schools. That is why graduating from an accredited American school and being exposed to the rigors of the American education system is an investment in your future.
Whether you want to study at a top USA university, a top USA college, a vocational or high school, a thorough understanding of how the American education system works is essential. Without a clear grasp of the American education system, an international student will find it difficult to make the right academic choices. It is no surprise that the American education system and the American school system host more international students than any other country in the world!
What is the writer's advice?
A.International students should not invest their future education in the US. 
B.International students should not study at a top USA university, a top USA college, a vocational or high school.
C.Without a clear grasp of the American education system, an international student can make the right academic choices
D.International students should have a thorough understanding of how the American education system works before going there to study.

Sleep is a natural process, and although a lot have been written about the subject, it is still surrounded by mystery. It is used by some as an escape from the world, and regarded by others as an irritating waste of time: some people get by on very little, others claim they cannot exist without at least ten hours, but nobody can do without sleep completely.
Our night’s sleep does not just consist of a steady phase of gradually deepening sleep. It alternates between two stages: Non-dreaming or ordinary sleep, and REM (rapid eye movement) or dreaming sleep. As soon as we fall asleep, we go straight into non-dreaming sleep for an hour or so, then into REM sleep for about 15 minutes, then back into non-dreaming sleep. It alternates in this way for the rest of the night, with non-dreaming sleep tending to last longer at the beginning of the night. Non-dreaming sleep occupies three-quarters of our night’s sleep, about a quarter of it deep and the rest fairly light.
It is widely believed that sleep repairs the body and makes good the damage caused by being awake. However, its main function is to refresh the brain. Experts believe that probably only about two-thirds of our sleep is necessary for repairing and refreshing the brain, with the most valuable sleep coming in the first few hours of the non-dreaming period, the last few hours of sleep are not so essential. The brain can manage quite well with reduced sleep as long as it is uninterrupted sleep. 
The quality of sleep is important. A study conducted in the USA looked at short sleepers, who slept for 5.5 hours on average, and long sleepers, who had 8.5 hours or more. It is discovered after a variety of tests that the long sleepers were poor sleepers, had twice as much REM sleep as the short sleepers, appeared to sleep longer to make up for poor sleep, and did not wake up in the morning refreshed. Similarly, people who sleep deeply do not necessarily get a better quality of sleep than shallow sleepers. Deep sleepers can feel tired the following day, so six hours of good sleep is worth more than eight hours of troubled sleep.
