1 . Is It Worth Buying Organic Food?

Organic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers have been willing to pay up to twice as much for goods with organic labels (标签). However, if you think paying a little more for organic food gets you a more nutritious (有营养的) and safer product, you might want to save your money. A study led by researchers at Stanford University says that organic products aren’t necessarily more nutritious, and they’re no less likely to suffer from disease-causing bacteria, either.

The latest results, published in the Annuals of Internal Medicine, suggest that buyers may be wasting their money. “We did not find strong evidence that organic food is more nutritious or healthier,” says Dr. Crystal Smith-Spangler from Stanford. “So consumers shouldn’t assume that one type of food has a lower risk or is safer.”

For their new study, Smith-Spangler and her colleagues conducted a review of two categories of research, including 17 studies that compared health outcomes between consumers of organic against traditional food products, and 223 studies that analyzed the nutritional content of the foods, including key vitamins, minerals and fats.

While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were too small, and the researchers were unwilling to make much of them until further studies confirm the trends.

Organic food is produced with fewer chemicals and more natural-growing practices, but that doesn’t always translate into a more nutritious or healthier product. The U.S. Department of Agriculture (USDA) states that “Whether you buy organic or not, finding the freshest foods available may have the biggest effect on taste.” Fresh food is at least as good as anything marketed as organic.

2 . Although most games have winners and losers, the goal of sports is not to win every game. The real goals include getting exercise, having fun, and learning important social skills, like sportsmanship.

Good sportsmanship is all about respect. Good sports (有体育精神的人) respect their teammates and also their opponents. They respect their coaches, and they also respect the referees or other officials involved in their games.     1     They shout at their teammates and they talk back to coaches or referees.

Kids usually learn sportsmanship good and bad from the adults in their lives.     2     If parents and coaches show disrespect for other fans, referees, or each other, kids will likely act the same way on the field.

    3     Some of them are very basic and easy to do, like shaking hands with other players before a game. Other examples may take a little more courage, such as acknowledging a great play made by the opposing team.

Learning good sportsmanship is important because it helps you develop an attitude of graciousness (礼貌) and respect that will carry over into all the other areas of your life.     4     Being a good sport in the classroom will eventually lead to being a good sport in the workplace.

So be a good sport in whatever you do!     5     When others see you acting in a way that makes it clear that winning isn’t the most important thing, you can move on to focusing on the important things, like having fum, getting exercise, and improving your skills!

A．Good sportsmanship can be shown in many ways.

B．However, bad sportsmanship is all about disrespect.

C．Players’ parents and coaches set examples that kids tend to follow.

D．We can be good sports by encouraging others but not laughing at them.

E．Starting as a good sport earlier will help you be a good sport as you get old.

F．If you’re a good sport on the field, you’ll also likely be a good sport in the classroom.

G．The example you set can be a powerful teaching tool for others.

3 . Some colors people see late at night could cause signs of clinical depression. That was the finding of a study that builds on earlier study findings. They show that individuals who live or work in low levels of light overnight can develop clinical depression. Doctors use the word “clinical depression” to describe severe form of depression. Signs may include loss of interest or pleasure in most activities, low energy levels and thoughts of death or suicide.

In the new study, American investigators designed an experiment that exposed hamsters（仓鼠）to different colors. The researchers chose hamsters because they are nocturnal, which means they sleep during the day and are active at night. The animals were separated into four groups. One group of hamsters was kept in the dark during their night-time period. Another group was placed in front of a blue light, a third group slept in front of a white light, while a fourth was put in front of a red light. After four weeks, the researchers noted how much sugary water the hamsters drank. They found that the most depressed animals drank the least amount of water.

Randy Nelson heads the Department of Neuroscience at Ohio State University. He says animals that slept in blue and white light appeared to be the most depressed. “What we saw is that these animals didn’t show any sleep uneasiness at all but they did mess up biological clock genes and they did show depressive sign while if they were in the dim（微弱）red light, they did not.”

Randy Nelson notes that photosensitive（感光）cells in the eyes have little to do with eyesight. He says these cells send signals to the area of the brain that controls what has been called the natural sleep-wake cycle.

He says there’s a lot of blue in white light. This explains why the blue light and white light hamsters appear to be more depressed than the hamsters seeing red light or darkness.

1. Researchers use hamsters in the experiment because ________.

A．they are similar to humans in dealing with colors

B．they are easy to observe and study

C．they are active at night and sleep during the day

D．they are sensitive to colors like human beings

2. What sign shows that the hamsters are being depressed?

A．They don’t sleep well.	B．They drink less sugary water.
C．Their eyesight becomes worse.	D．Their energy level becomes low.

3. ________ tends to cause hamsters to be depressed.

A．Blue light	B．Red light
C．Dim light	D．Darkness

4. In which situation are people less likely to develop depression?

A．Not being exposed to dim red light when using computers.

B．Living or working in low levels of light overnight.

C．Equipping their computer screens to put it more in the reddish light.

D．Going to see doctors of clinical depression regularly for help.

Modern-day robots are programmed to handle tasks that are normally carried out by humans. They are faster and     1     (accurate) than human workers and never ask     2     a pay rise or take breaks! Robots are also able to work in dangerous situations.

Researchers at the University of Arkansas in the United States say that the mobile robots which     3    (create) already are ideal for the job of hospital attendants. These mobile robots store a     4    (detail) map of the hospital in their memory. The robots’ sensors can detect     5    (barrier) and quickly get out of the way. Although these robots cannot go up and down stairs, they know how     6    (press) a button of an elevator.

Researchers at a Massachusetts’ university are creating the first robot     7     can constantly change its shape according to the task it has to do. These robots are called polymorphic robots. “Polymorphic” means     8     ability to take different forms. A 3D printer is placed inside the robot to create the desired shape. The entire process of changing forms in this manner is called the rapid printing technology which is     9    (fair) common in the car industry to produce complex 3D structures quickly. Once the robot has performed its task, it can be melted down     10     recycled into another useful part by the 3D printer.

9 . Have you ever looked at a fashionable item of clothing and felt confused? If so, your confusion may have made sense.

Several months ago, high fashion brand Balenciaga released a “T-shirt shirt”, which is a shirt sewn on the front of a T-shirt. The unusual design has certainly confused a lot of people.

But the “double shirt” isn’t fighting alone on the frontier of strange fashion. Ever since US shoe manufacturer Crocs released its famous hole-filled foam shoes, the so-called “ugly fashion” hasn’t showed any signs of slowing down, the Business of Fashion website noted.

British designer Paul Surridge believes that the rise of ugly fashion is a sign that people are bored with looking perfect all the time. “Fashion thrives (v. 蓬勃发展) on novelty”, he told the Financial Times.

Indeed, fashion is all about changes. Something that’s considered uncool one minute can then turn out to be the latest must-have fashion item the next.

And in the eyes of US fashion writer Megan Collins, ugly doesn’t necessarily mean the design of the item is ugly. After all, ugly is something subjective. “Ugly fashion means ‘not the mainstream’— it is not what everyone’s wearing; it is not what the general population considers as ‘in’ right now,” she told style news site Fashionista.

But throughout the history of fashion, when any new trend appears, most people tend to hate it, before it eventually becomes loved. As Italian designer Miuccia Prada told The New York Times, “Maybe because it is newer, ugly is attractive. Ugly is exciting.”

Meanwhile, popular social media fashion bloggers also help people to pick up new ugly fashion trends. These bloggers express themselves through their clothes, showing their unique personalities and making statements with their wardrobe choices. However, as Clever-ish Magazine noted, just being comfortable in your own skin could actually be “the best look”.

“I personally love having a unique expression because without ugly fashion and diversity, we’d all look the same,” Australian fashion influencer and model Zanita Whittington told Fashionista. “I appreciate anything that’s out of the norm(n. 规范).”

1. The underlined word “in” in the passage could be replaced by ____________.

A．ugly	B．fashionable
C．affordable	D．expensive

2. What will some social media fashion bloggers do to show their personalities?

A．They will dress themselves to look perfect.

B．They will try some new and exciting clothes.

C．They will make statements with others’ clothes choices.

D．They will express themselves by wearing ugly clothes.

3. What can we infer from Zanita Whittington’s words?

A．She is in favor of ugly fashion trends.

B．She doesn’t care about fashion at all.

C．She hopes to be the same as others.

D．She wants to look ugly as a model.

One Saturday morning in about 9:00, I was walking to a supermarket nearby while suddenly I heard a loud crash just about 10 meters away. I went up and find that two taxis were badly damaged, with one door of a car knock off. One driver was bleeding heavily and other was trapped in the taxi. As soon as passer-by around saw what had happened, they were all came to offer help. Soon the police and an ambulance arrived. Judging from the stopping tracks on the road, it was obviously that the two taxi drivers were driving too fast as both of them were eager to taking more passengers. I think, when travelling, it is important to obey traffic rules, because caring about others’ lives mean caring about our own lives.
