There have always been a lot of commonly believed but false ideas about being fat and doing exercise. Some people believe that they can’t help putting on weight as they get older, while others hold that if they stop exercising, their muscles will turn into fat. Here are some more myths:

I’ll never lose weight--I come from a fat family

Wrong! While we can't change the body type we are born with, we can't blame our genes for making us fat. There's plenty of evidence that fatness runs in families, and the main reason is that they share the same habit of eating too much and exercise too little.

I am fat because I burn calories slowly

Wrong! Fatness is not caused by a slow metabolism(新陈代谢).In fact, although fat people consume more energy than slim people, they also fail to realize how much they eat! Keeping a diary can help you work out your daily food intake mom accurately.

Exercise is boring

Wrong! Anything will become boring if you do it repetitively. The key is to develop a balanced and varied program that's fun as well as progressive. If you enjoy a Sunday walk, take a different mute. If you do yoga, try a Tai chi class. If you like swiping, set yourself a distance or time challenge.

No pain, no gain

Wrong! Exercise is not meant to hurt. Indeed, pain is you body telling you something's wrong, and continuing to exercise could lead to serious injury. You may experience mild discomfort as you begin to exercise regularly, but this is your body adapting to the positive changes in your lifestyle and the aches should disappear relatively quickly. If they don't, rest and seek medical advice.

There are many people you are well advised to treat kindly: Your child’s teacher, your husband or wife, your boss and so on.

Until now, that best-behavior-required list has not included your Uber(优步) driver, or taxi drivers. Old thinking: Hey, they’re here to serve me. I don’t have to make a special effort to be nice to them.

Dangerously wrong.

A recent New York Times story told the educative tale of a Uber passenger, Hussein Kanji, who says he’s really not sure how he made his driver angry. All he knows is that his driver-generated rating(评分) went way down and the wait for a Uber car became hours instead of minutes.

Be careful, Uberians: If you’re feeling angry when you get into the back seat and you give your driver the silent treatment, your reputation may get damaged in the driver-generated ratings. If you’re among the people described as “generally negative” by one Uber driver, watch out.

Uber isn’t the only front on this battlefield. The ability to rate someone’s service is one of the successes of the Internet. It helps everyone weed out people with bad attitudes and worse habits.

These ratings should cut both ways. A while back, the auction(竞买) site eBay made many of its sellers angry when it started preventing them from giving negative ratings to buyers. Until then, sellers and buyers had threatened each other with negative reviews. Too many negative reviews could get you thrown off.

Then eBay shifted the balance of power to buyers. Sellers can still write a bad comment, but the overall rating cannot be anything but positive. Thus eBay has become a place where all is for the best. Think positive!

We know that being nice to people all day can be exhausting. We’ve also seen people who shout at those who don’t measure up to their expectations for service.

Uber is reportedly about to spread worldwide. It is a welcome competitor because it fits the needs of customers in a new way. We know Uber is a two-way street. But drivers who get too picky may end up with no passengers.

Everyone, behave!

1.Negative driver-generated ratings mean that ________.

A. Uber drivers will never serve those customers

B. drivers are too slow to pick up customers

C. customers have to wait for a longer time when using Uber cars

D. customers have done damage to Uber cars

2.The underlined phrase “weed out” (Para. 6) can best be replaced by _____.

A. hate B. get rid of

C. value D. win back

3.The example of eBay in the article is probably meant to show that ________.

A. in the Internet age, buyers have always had the advantage of ratings

B. the power of ratings should be given to both sides of a service

C. the main reason why eBay has become a successful auction site

D. controversy between customers and sellers has only come about recently

4.The author has written this article to ________.

A. show that when using Uber, your behavior directly affects the service you get

B. prove that giving and receiving bad ratings can influence your life

C. suggest that tools like Uber and eBay can reflect what kind of person you are

D. stress that both customers and service providers should be respectful and positive

Clean water is not only important for food production, but necessary for our life. However, large numbers of people in Asia and Sub-Saharan Africa are going without. The World Health Organization reports that almost 4,000 children die each day for dirty water or lack of water.

Agriculture is the primary user of water at 70–85% of fresh water in the world. Industrial uses of water don’t often come to mind, but you may be surprised to know that industry uses 59% of the water supply in developed countries.

Home use takes up only 8% in the world. But as cities grow, the local government has to cut down on water use. Many cities are turning to privatization (私有化) of water as a method of controlling use. The poor are paying as much as a quarter of their monthly income for water in some developing countries.

In 60% of large European cities, groundwater is being used at a faster rate. People are saving water by simply using less and being careful with what they do use. Sometimes it’s as simple as not throwing out water that they could use elsewhere.

In Australia overuse of water has always been a problem. The Australian government has encouraged households and industries to collect rainwater and reuse water from showers. Technology is helping householders for shower and bath water for reuse in toilets or gardens.

The U.S. Environmental Protection Agency has made a water saving program designed to encourage families and businesses to examine their water use and save more water. Good water management has been considered by scientists and the UN as the key to solving the water problem. We can all work together to protect our valuable water in our daily life.

1.In developed countries, most water is used by ______.

A. industry B. agriculture

C. families D. businesses

2.To save water, what do Australians and Europeans both choose to do?

A. Find more groundwater.

B. Make good use of rainwater.

C. Encourage people to have fewer showers

D. Recycle water for a second use.

3.According to scientists, to deal with water shortage, the most important is to ______.

A. popularize privatization of water

B. cut down on water use at home

C. have good control over water use

D. introduce water-saving technologies

4.What would be the best title for the passage?

A. Water—the source of all lives

B. Save water, save the world

C. New ways to save water

D. Water and people’s health

It seems that electronic devices just keep getting smaller. Scientists in the United States have announced the creation of the first transistor with only two dimensions(二维).

A transistor is a small electronic device that transfers or carries electronic current. Scientists hope these new 2D transistors will be used for building high-resolution(高分辨率)displays that need very little energy.

Two groups of scientists created these 2D transistors. They report that the transistors are only a few atoms thick.

Usually transistors are made with the element silicon(硅). Computer processors, memory chips, TV screens and other electronic devices contain billions of silicon-based transistors. But these very small electrical parts have certain limitations.

Dimitris Ioannou is an electrical engineering professor at George Mason University. He says the traditional transistor has been improved as much as it can be.He adds that researchers have been looking for new materials with special features and they want transistors to be seen through and soft.

“If the layers are very thin, the transistor can become flexible, so it doesn't have to be rigid(坚硬的), like it would be in a silicon chip. So people can think of applications like wearable electronics, television screens and other things,” said Ioannou.

These new transistors can also carry higher current. They also can move the current much faster than traditional transistors. This is important for high-definition screens.

Dimitris Ioannou says the scientific success could prove very useful in the future. "Now, how good and how useful it will be, it's still in the stage of research, but it certainly is an advance," said Ioannou.

1.Which of the following statements about the newly created transistor is TRUE?

A. They are expected to be used in high-resolution displays.

B. The transistors are made with the element silicon.

C. They are rigid, just like traditional transistors.

D. They have already been put into actual use.

2.What does the underlined sentence in Paragraph 5 mean?

A. The traditional transistors have been changed into two-dimensional ones.

B. Many of the traditional transistors have been improved over the years.

C. The traditional transistor has been developed to its fullest.

D. The traditional transistor has been developed quite well.

3.What is Dimitris Ioannou's attitude towards the creation of the new transistors?

A. Negative. B. Neutral.

C. Indifferent. D. Positive.
