Article: They tell us when to get up or when we're running late for work and whether we are in danger of missing our favourite TV programme. But while our daily routines rely on clocks that tell us the time, science is discovering that our well-being is influenced by a very different kind of timepiece. Circadian rhythms---the human body's own internal clock---have a powerful influence on our health and behaviour. _ are programmed from birth and control functions ranging from temperature and blood pressure to sleep patterns. In recent years researchers have also discovered that this built-in mechanism can influence everything from the way we react to medicines to how well we learn music. The latest example, from experts at Harvard University in the US, shows that the human body clock can even dictate whether or not we are likely to tell the truth. Researchers found it was easier for people to fib  in the afternoon because, as they were tired, the self control that would normally prevent them from lying started to break down. Tiredness made it harder to resist the temptation to tell lies---especially if it meant they got a financial reward at the end. "The body clock has a great effect on us all," says Professor Jim Horne from the Sleep Research Centre at Loughborough University. "Most people tend to feel good around late morning and then decline in the early afternoon. But the time most of us will feel our sharpest is between 6pm and 8pm. That's because sleepiness tends to build up throughout the day. By early evening our body clock kicks in to wake us up. One reason may be to ensure we get home safely. When our ancestors were coming home after hunting all day their internal clocks kicked in to get them home in one piece." So what effects do circadian rhythms have and what's the best time of day to take advantage of them? 
 Question: According to the passage, when are people most quick-thinking? 
 Options: (A) In the morning. (B) Around midday. (C) In the late afternoon. (D) In the early evening.

Article: This is a tense time for students in America,with the exam season in full swing and the stress and anxiety being felt across the country.At some universities,students are reviewing their lessons,knowing that in a few weeks the stress will be over once they put pen to paper in that exam hall.For others,however,that stress and anxiety may well last a while longer as lecturers continue to refuse to set exams.No one knows when things will get back to normal. The reason behind this trouble is the ongoing argument in higher education between lecturers and employers over pay.The Association of University Teachers(AUT)are currently taking industrial action because of the fact that lecturers have been underpaid for years.Vice-presidents of the universities,who enjoy six-figure salaries,are not making any noises to suggest that this will change in the near future. The National Union of Students(NUS) ly believes that our lecturers should be better paid,and that the promises made to them during the top-up fees debate about extra income must be kept. It's shameful that 1ecturers have had to take industrial action to achieve better pay and conditions while vice-presidents'own salaries have risen 25%over the past three years.But the students who are suffering as a result of the argument must be put first.We do not agree with the attitude taken by the AUT,which is refusing to set exams.We admit that the decision to take this course of action was democratically reached.However,it is having the biggest effect on our members at this moment in time and we will continue to let the AUT know the results of this. We call on both sides to sort this mess out.Hopefully then our members can get the horrible exam season Out of the way and start planning,and enjoying,their upcoming summer holiday. 
 Question: What is the students'opinion about the argument? 
 Options: (A) They think it's wrong that the lecturers ask for the better pay. (B) They think what the vice-presidents have done is reasonable and understandable. (C) They totally agree with what the lecturers have done and support them. (D) They hope that the lecturers can set exams as soon as possible.

Article: While others look away from trouble, this lady digs in and gets to work. Gretchen Buchenholz, the native New Yorker and mother of six, has worked on behalf of needy and margin1alized families for years in the city. She does everything from buy groceries for homeless families to start schools for children. In 1974 she founded Merricat's Castle, a nursery school that opened its doors to kids of all racial and economic backgrounds, the able-bodied as well as those with disabilities or terminal illnesses. She founded the Association to Benefit Children (ABC), the nonprofit group, some 20 years ago. The story of how she started ABC is pretty amazing. In 1984 she was on her way to a government office to get a day-care permit when, by accident, she entered a room where homeless families were waiting to be placed in a " welfare hotel." She saw three bare cribs   with babies lying in them. The children wore no diapers (their parents couldn't afford them), and the room was filthy  . After talking to the parents and learning that they and their children were hungry, Gretchen marched out and bought bread, peanut butter, apple juice and diapers. Then she started making phone calls. She dialed the American Red Cross, City Hall and The New York Times. Gretchen has made many people see that we need to recognize these children are not different from our own, and we need to join in and help. Too often, people look away from suffering. But she sets us an example that we should gain strength to do something about it. 
 Question: She went to the government office   _  . 
 Options: (A) to help those homeless people in the room (B) to apply for a permit for ABC (C) to call on the government to help those homeless children (D) to get permission to look after babies during the day
