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.

7 . 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.

9 . Whizzfizzing Festival

As one of the Home Counties to the north and west of London, Buchinghamshire is known for the rolling Chiltern Hills, its pretty villages, and the much-loved children’s author Roald Dahl.

The writer who penned Charlie and the Chocolate Factory, The Witches, Matilda and The Big Friendly Giant is the inspiration for the Whizzfizzing Festival, which will transform the market-town of Aylesbury into all kinds of music, color and fun on Saturday, 1 July.

Formerly known as The Roald Dahl Festival, this year’s event will involve a broad range of children’s films and bring to life some of their best-loved characters — from Alice in Wonderland and Gruffalo to The Big Friendly Giant and Harry Potter.

Things to See and Do

The festivals start at 11 a.m. with a colorful children’s parade. More than 650 local school children and teachers, many in fancy dress, will march through the town carrying giant carnival puppets(木偶), with thousands of audiences lining the street to watch.

The parade will be followed by a range of child-friendly activities and workshops held in venues across the town.

Don’t be late for the Mad Hatters Tea Party in the Bucks County Museum, catch a splendid screening of a Roald Dahl film in the Old Court House, watch leading children’s authors, including Julian Clary, and read in the Market Square.

CBeebies’ children’s chef Katy Ashworth will once again cook up a storm with her interactive Concoction Kitchen, located outside Hale Leys Shopping Centre. Little chefs will have lots of opportunities to get involved in preparing, cooking — and best of all, tasting — Katy’s wonderful dishes.

With hands-on arts and crafts workshops, storytelling sessions, live music, a fancy dress competition, street theatre and more, there is something for everyone.

10 . When he was young, Louis Armstrong was taking what was called “Creole jazz”, which was also called dance music, and combining it with trumpeter(小号手) Buddy Bolden, to create what would eventually become today’s jazz.

Armstrong accomplished this with almost no formal training. He received little training before he was placed in the New Orleans Colored Waif’s Home at the age of 12, after a run-in(小争执) with the police. The punishment turned out to be a mixed blessing, for he also had the opportunity to play in a real band.

While at the Waif’s, Armstrong also got the chance to hear some of the city’s finest musicians. Cornetist Freddie Keppard performed in a nearby club. So did trumpeter and bandleader King Joe Oliver, who took the boy under his wing and taught him how to read music and work on his playing technique.

When Oliver left for Chicago, Armstrong chose to stay in New Orleans and work with some of the other top musicians of the day. In Chicago, King Oliver offered him a place in his band in 1922. It became Armstrong’s biggest challenge yet — the band had no parts written for trumpet, so he was forced to listen to King Oliver and improvise(即兴创作).

Soon, Armstrong’s undeniable talent was getting noticed. Even classically trained musicians would come to hear the incredible sounds this young man created.

Lil Hardin, the band’s piano player and the future Mrs. Armstrong, explained that Oliver kept Armstrong in the second trumpet-chair so that Oliver would still be “King”. Hardin convinced him to leave the band.

Armstrong moved to New York City in 1924 to join Fletcher Henderson’s band and then flew solo. In 1925, Armstrong put together the Hot Five, expanding his popularity even more. Armstrong recorded his first composition, Cornet Chop Suey, one of the most copied jazz solos of all time. This monumental 1928 recording blends(混合) artistry, endurance and showmanship that has rarely, if ever, been matched in jazz.

1. What does the underlined word “this” refer to in the second paragraph?

A．To play dance music.	B．To work with Buddy Bolden.
C．To play a jazz instrument well.	D．To create modern jazz music.

2. Who taught Louis Armstrong how to play music in the early time?

A．Buddy Bolden.	B．Lil Hardin.
C．King Joe Oliver.	D．Cornetist Freddie Keppard.

3. Why did Louis Armstrong Leave King Oliver’s band?

A．Because he wanted to get married in New York.

B．Because his talent could not develop completely.

C．Because he got a better opportunity in New York.

D．Because the man forced him to leave the band.

4. What’s the main idea of the passage?

A．It asks readers to know more about modern jazz.

B．It introduces one of the greatest jazz musicians.

C．It introduces the development of jazz.

D．It describes the importance of talent in playing jazz.
