【題目】In a time when a dangerous number of people are overweight, many people seem to have forgotten the most important way to keep healthy and slim---exercise. And as a new study carried out on mice in the lab has shown, exercise done early in life can reward you in your adult years.
A team of researchers at the University of California studied the effects of early exercise on adult physical activity, body mass and eating. They found that early-age exercise in mice has positive effects on adult levels of voluntary exercise in addition to reducing body mass.
“These results may have an effect on the importance of regular physical education in elementary and middle schools,” said Theodore Garland, a professor of biology, who led the research project. “If kids exercise regularly through their school years, then they may be more likely to exercise as adults, which could have far-reaching positive effects on human health and well-being.”
Although the positive effects of early-life exercise lasted for only one week, it is important to note that one week in the life of a mouse is the same as about nine months for humans. “Our results suggest that any positive effects of early-life exercise on adult exercise will need to be kept up if they are to be long-lasting.”
His team of researchers found, too, that all mice that had access to early exercise were lighter in weight than non-exercised mice.
Garland explained that, in general, exercise will stimulate appetite sooner or later. However, it is possible that certain types of exercise, done for certain periods of time or at certain light levels, might not stimulate appetite much, if at all, at least in some individuals.
“If we could understand what sorts of exercise these might be, then we might be able to tailor exercise recommendations in a way that would bring the benefits of exercise without increase in appetite, leading to a better chance of weight loss,” he said.
【1】How long do the positive effects of early-life exercise last for a mouse?
A. One day B. One week
C. One month D. Nine months
【2】Which of the following statements is TRUE according to the article?
A. More study is needed to better understand the effects of different types of exercise.
B. Early-life exercise has life-long positive effects on people
C. Kids should be encouraged to do exercise as early as possible to ensure physical health.
D. The new study on mice mainly focused on how exercise affects appetite.
【3】The underlined word “stimulate” in the last but one paragraph is closest in meaning to _______.
A. decline B. improve C. vary D. harm
【4】 What is the article mainly about?
A. New ways to fight against being overweight.
B. The positive effects of mice
C.The possible risks of doing exercise
D. The positive effects of early- life exercise.
【答案】

【題目】It’s an ordinary morning,like all the others.But instead of being woken up by the buzzing of an alarm clock, you’ll be roused by the smell of freshly made coffee,light entering your room as the curtains open automatically,and a gentle back massage(按摩)provided by your high-tech bed.
This is what a typical(典型的) person's life will be like two decades from now,according to The Guardian. Want to know more?
After you get up, your apartment will be like an electronic orchestra with you as the conductor. With simple moves of your hand and spoken instructions, you’ll be able to control your apartment’s temperature, humidity, music and lighting. You’ll be able to look through the day’s news on translucent screens while your breakfast waits for you in the automatic oven.
As you move into your kitchen, you might accidentally hit your toe on a cupboard. If you do, you’ll grab your cell phone and open the diagnostics(診斷) app. Inside your phone there will be a tiny microchip(芯片) that uses X-ray waves to scan your body. The scan will tell whether your toe is bruised or broken.
After breakfast, your driverless car will take you to work. While you “drive”, your central computer system will suggest a list of chores(家務(wù)事) that your housekeeping robots can do that day and it will also remind you to buy a gift for your mother’s upcoming birthday.
As you can see, with the help of advanced technology, our lives will be more efficient(有效率的). Technology will mitigate our forgetfulness and free us of many small burdens that distract us, such as buying a ticket. Our brain will therefore be able to focus on more important things like preparing for a presentation or doing “deep thinking”.
However, the development of technology might have some disadvantages as well. By 2036, we’ll be relying heavily on the virtual(虛擬的) world, which will mean that all of our data will be stored in the cloud, a remote digital storage system with near limitless capacity(容量). That will increase the possibility of someone else accessing, sharing or manipulating(操控) our personal information.
【1】What might be the author’s purpose in writing the text?
A. To stress the importance of developing technology.
B. To remind people not to depend too much on computers.
C. To introduce one new invention that will benefit our future lives.
D. To describe how advanced technologies will affect our future lives.
【2】According to the text, in two decades, ________.
A. you’ll be able to rely on an electronic orchestra to wake you up instead of an alarm clock
B. a tiny microchip in your phone will treat you when you are sick
C. you will be able to adjust the conditions of your apartment via oral instructions or simple hand gestures
D. technology will be smart enough to help us with important things like preparing for a presentation
【3】What does the underlined word “mitigate” in Paragraph 6 mean?
A. Make up for. B. Worsen. C. Cure. D. Take advantage of.

As it is often the case, when people are attending meetings, having meals or waiting for buses, you can always find them addicting to their phones, completely ignoring others.
This is really a common phenomena in our life. The reason is why smart phones nowadays can be used for people to play mobile games and kept in touch with friends through QQ and WeChat. Therefore, too much exposure to phones are bad for people in terms of health. Moreover, people involved in phones fail to communicate well with these around them.
As far as I am concerned, people should wisely make use of their phones to help their work and study. Meanwhile, care much about their family and friends rather than mobile phones.
