Charles Czeisler, a professor at Harvard Medical School, and his colleagues got a small group of people for an experiment. For five days in a row, the people read either a paper book or an iPad for four hours before sleep. Their sleep patterns were monitored all night. Before and after each trial period, the people took hourly blood tests to paint a day-long picture of just how much melatonin was in their blood at any given time. When subjects read on the iPad as compared to the paper books, they reported feeling less sleepy at night and less active the following morning. People also took longer to fall asleep on the iPad nights, and the blood tests showed that their melatonin secretion was delayed by an hour and a half. The researchers conclude in today's journal article that given the rise of e-readers and the increasingly widespread use of e-things among children and adolescents, more research into the long-term consequences of these devices on health and safety is urgently needed. Czeisler and colleagues go on, in the research paper, to note:"Reading an iPad in bed may increase cancer risk." However, software has been developed that can reduce some of the blue light from the screens of phones and computers according to time of day, and there are also glasses that are made to filter short wavelengths. While they seem like a logical solution for the nighttime tech users, it needs more research. Question: In Charles Czeislers experiment, all the subjects were asked to _ . - sit in a row and receive the strict tests - have their sleep patterns observed all night - read a paper book and an iPad at the same time - have their blood tested per hour during the trial
have their sleep patterns observed all night

Read the following article and select the best answer. Article: Normally a student must attend a certain number of courses in order to graduate, and each course that he attends gives him a credit, which he may count towards a degree. In many American universities the total work for a degree consists of thirty-six courses, each lasting for a term. A typical course consists of three classes per week for fifteen weeks; while attending a university a student will probably attend two terms a year. It is possible to spread a period of work for the degree over a longer period. It is also possible for a student to move between one university and another during his degree course, though this in fact is not done as a regular practice. For every course that he follows a student is given a grade, which is recorded and available for the student to show employers. All this imposes a constant pressure and strain of study, but in spite of this some students still find time for great activities in student affairs. Elections to positions in the student union arouse great interests. Students who are qualified usually perform the effective work of the student union. With the big numbers of students, the operation of the system does involve a certain number of activities. A student who has held one of these positions in the union is much respected and it willbe of benefitto him. Question: The ed phrase "be of benefit" means _ . - be demanding - be pleasant - be rewarding - be considerate
be rewarding

Read the following article and select the best answer. Article: She is quiet, soft-spoken and has a kind face and a strong heart. She is my mom, Lili. When I was nine, Lili quitted her job and started her own business. She said she didn't want to stay at home and work as a housewife: "It's a waste of life." Lili became so busy that she spent less and less time with me. She didn't help me with my schoolwork. It was, in her words, "so that you can develop your independence". We quarreled because she rarely showed up at parents' meetings. Like mother, like daughter. I have many things in common with Lili. I want everything to be under control. I want to be perfect and I don't expect other people to help me. I push myself hard to achieve my goals. After I started to go to high school, Lili and I were too busy to communicate much with each other. In biology class I began to be depressed. When the teacher showed us a picture of a butterfly, I was scared and screamed. I had a vision of thousands of butterflies flying toward me. That night I told Lili about it. The next morning, I saw that she had red eyes with black circles around them. She took me to see a therapist . Three hours later, the therapist told Lili that my life was like a wheel spinning faster and faster and that was the reason for what had happened to me. I only realized it when my body couldn't stand the pressure anymore. At these words, Lili burst into tears. "It's all my fault, she's just a kid and I didn't have time to take care of her...." To be honest, I had never seen Lili cry before. After that, Lili began to spend more time at home, cooking and dragging me to do sports. I realized she was the one who would always be there when I was in real trouble. No mom is perfect, but she is the one who really cares about her kid. Question: What can we learn from the passage? - Most women don't want to be a housewife. - Most children want their mothers to accompany them at home. - We need to understand our mothers' busy life. - Although mothers are not perfect, they all love the children
Although mothers are not perfect, they all love the children

And of course, many of these are on the World Heritage List .But the WHL contains a lot of sites that are not so obvious. Let's look at a few of them. Robben Island in South Africa This island was used through the centuries as a prison, a hospital and a military base. But it's probably the most famous as a prison for political prisoners in the twentieth century. Nelson Mandela was one of its residents. The WHL says it represents "the victory of democracy and freedom over oppression and racism " The Darjeeling Himalayan Railway in India This railway was opened in 1881 and is still operating today. It crossed a difficult area of mountain landscape and it is a great example of railway engineering. The WHL says that it is "the first, and still the most outstanding example of a hill passenger railway." Borders of France and Spain This is an area of great natural beauty and the mountains have many interesting geological formations. But it is also an area of small farms. Surprisingly, people there still use a type of agriculture that used to be common in mountainous areas of Europe but has almost completely disappeared in modern times. Alto Douro, Portugal This is an area in the North of Portugal where wine has been produced for thousands of years. The WHL says that this long tradition of wine making "has produced a cultural landscape of outstanding beauty that reflects its technological, social and economic evolution". Rio Platano Reserve, Honduras The WHL says that this site is "one of the few remains of a humid tropical forest in Central America".
