Swimming is very popular. People like swimming in summer because water makes people feel cool. If you like swimming and swim in a wrong place, it may not be safe. These years, a lot of people died when they were enjoying themselves in the water, and most of them were students. But some people are not careful in swimming. They often think they swim so well that nothing will happen to them in water. Summer is here again. If you go swimming in summer, don't forget that better swimmers have died in water. They died because they were not careful not because they could not swim. So don't get into water when you are alone. If there is a "No Swimming" sign, don't get into water. If you remember these, swimming will be safer.

Every day, people come into contact with thousands of chemicals. These chemicals are said to be harmless to human health. In fact,the chemicals are considered so safe that we wash with them. We put them on our bodies and even our faces. Other chemical products are used throughout our homes.

By the time you walk out of your front door, you have already been exposed to thousands of chemicals.

On its own, each chemical seems harmless. But in combination with other chemicals, they may become deadly. That is the finding of a two-year study by a high-profile task force of scientists. The task force was told to investigate the cancer-causing possibility of chemical mixtures.

Linda Gulliver was one of 174 scientists on the task force. Their job was to study the cancer-causing potential of 85 chemicals. All 85 are said to be common in the environment.

Ms. Gulliver explains that chemicals have the potential or y to form dangerous mixtures. Even simple minerals can become dangerous when mixed with chemicals found in plastics or beauty products.

Working in groups, the scientists explored how different chemical mixtures could lead to cancer. Ms. Gulliver’s team looked at the ability of different combinations to support the in- crease of malignant (恶性的) human cells.

She says the current way to identify whether chemicals cause cancer is to test them one at a time. This method leads, she adds, to a long list of supposedly “safe” chemicals. She and her team say that approach needs to change.

“We definitely need certain research… to find out what mixtures of chemicals would be more harmful than others; what groups of chemicals, when together, would produce more harmful effects. And at the moment, that is not known.”

An estimated one in five cancers has been linked to chemical exposure. It may turn out that the cancer-causing villain (恶棍) is not a single chemical at all.

1.What effect may one single chemical have on us according to the text?

A. It may let us suffer from cancer.

B. It may not cause danger to us.

C. It may destroy our body.

D. It may let our body make a change.

2.What can we learn about Ms. Gulliver’s research?

A. She has found reasons for five kinds of cancers.

B. She has found that only one chemical can cause cancer.

C. She has found 85 cancer-causing chemicals.

D. She is not sure what mixtures of chemicals are more harmful.

3.According to the text? we can infer that the study .

A. is just wasting time and money

B. is in need of great efforts

C. will cause panic in public

D. will be resisted by the public

4.What is the best title for the text?

A. Mixtures of Safe Chemicals May Cause Cancer

B. Being Exposed to One Chemical Is Dangerous

C. How Mixtures of Safe Chemicals Come into Being?

D. What Is the Real Cause for Cancer?

Half off usually unaffordable products?Only $49.99 for that $100.00 dinner?That’s the magic of Groupon,but for some small business owners the “great business” offered by Groupon can be equal to the kiss of death.How could that occur?

The math of Groupon seems simple at a glance,but upon further inspection the numbers don’t add up when it comes to smaller businesses.A Groupon typically offers a 50% discount on a product or service;then the remaining profit is divided between Groupon and the small business.While Groupon has already received the profit in advance,the merchant is left waiting for their cut.Those worrying numbers are assuming the price cut is 50/50,which,in some cases,is being generous.

When you break it down to numbers,a Groupon deal seems disastrous,but it’s not only the numbers small business owners have to worry about.The point of Groupon deals is to attract new and hopefully long term customers.Yet,does this actually happen?The majority of consumers buying the Groupon are there for the bargain and don’t return after using their Groupon.CFHS Junior Angelita Pope stated,“I love the deals offered by Groupon!They can really save you so much money.”However,she went on to say that she hadn’t returned once to any of the businesses after using her Groupon.

For some small businesses,the pressure lies with the responses of their loyal customers,who watch as new faces get the same product or service for half the price that they have been paying for years.When you break it down,Groupon indicates that the business offering the deal is not only willing to be flexible with their price,but also that their product or service isn’t worth the price they’re charging for.When combining these factors,it’s no wonder loyal customers are put off by the idea of their favorite shop offering Groupons.

Now I by no means say Groupons have bad effects on all businesses;however the storm of Groupon is actually a disaster for a small business.

1.What is good about Groupon?

A. It can offer a large discount.

B. It helps add up the numbers.

C. It can improve the quality of the product.

D. It brings small business owners more profit.

2.CFHS Junior Angelita Pope’s statement suggests that    .

A. small business owners needn’t worry about deals

B. people like using Groupon in the same business

C. the purpose of Groupon is to promote business

D. Groupon may not bring customers back

3.What does the underlined word “they” in Paragraph 4 refer to?

A. New faces. B. Loyal customers.

C. Groupon dealers. D. Small businesses.

4.What could be the best title for the text?

A. A new business trend—Groupon dealing

B. The development of a Groupon company

C. The effects of Groupon on small businesses

D. A fantastic shopping experience—Groupon
