People are being lured(引诱)onto Facebook with the promise of a fun, free service, and don’t realize that they’re paying for it by giving up loads of personal information.Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages.

Most Facebook users don’t realize this is happening.Even if they know what the company is up to, they still have no idea what they’re paying for Facebook, because people don’t really know what their personal details are worth.

The biggest problem, however, is that the company keeps changing the rules.Early on, you could keep everything private.That was the great thing about Facebook—you could create your own little private network.Last year, the company changed its privacy rules so that many things—your city, your photo, your friends’ names—were set, by default(默认), to be shared with everyone on the Internet.

According to Facebook’s vice president Elliot Schrage, the company is simply making changes to improve its service, and if people don’t share information, they have a “less satisfying experience.”

Some critics think this is more about Facebook looking to make more money.Its original business model, which involved selling ads and putting them at the side of the page, totally failed.Who wants to look at ads when they’re online connecting with their friends?

The privacy issue has already landed Facebook in hot water in Washington.In April, Senator Charles Schumer called on Facebook to change its privacy policy.He also urged the Commission to set guidelines for social-networking sites.“I think the senators rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them,” Schrage admits.

I suspect that whatever Facebook has done so far to invade(侵犯)our privacy, it’s only the beginning,which is why I’m considering deactivating(撤销) my account.Facebook is a handy site, but I’m upset by the idea that my information is in the hands of people I don’t trust.That is too high a price to pay.

Researchers Jose Cordova and Erich Astudillo have discovered a new molecule(分子) that kills the bacteria Streptococcus Mutans, long known to be responsible for breaking down sugars in food in the mouth, which damages tooth leading to decay(腐烂). The new molecule they call “Keep 32” has been found to kill the bacteria.

The two have applied for a patent(专利) on their discovery and have also begun a marketing strategy aimed at both oral care products and food products. They say either product, if left in the mouth for just 60 seconds ,will kill all the harmful bacteria in the mouth and keep them at bay for several hours. If the new molecule passes health and safety tests, the two believe products using their new molecule should be on the market in as little as a year and a half. They expect the market for such a product to reach $300 million in just the first year.

The two have been working together since 2005 using money from the Founder Institute and say the aim is to approve the process for creating the molecule they’ve discovered for big companies like Procter & Gamble, Colgate even candy companies such as Hershey’s. In interviews, Astudillo has suggested that the two researchers are already heavily into discussion with several companies, some of which are interested in buying the patent once it is approved.

Over the years many products have come on the scene with announcement of reducing tooth decay and even the loss of teeth, but other than the introduction of fluoride(氟化物) into drinking water, not much progress has been made. If the announcement made by this new team proves true however, it could foresee a mark in saving the world of tooth decay as well as helping to improve the health for millions of people as tooth decay has been linked to many other health problems throughout the body including heart attacks.

1.The underlined word “them” in Para. 2 refers to _________.

A. oral care products B. food products

C. new molecules D. the harmful bacteria

2.The phrase “come on the scene” in Para. 4 is closest in meaning to __________.

A. performed B. occurred

C. existed D. arrived

3.What has been a way to reduce tooth decay and even the loss of teeth over the years?

A. Using the molecule “Keep 32”.

B. Killing the bacteria Mutans.

C. Introducing fluoride into drinking water.

D. Cooperating with some big companies.

4.This passage mainly tells us that ___________.

A. many health problems are closely connected to tooth decay

B. the discovery of a new molecule will greatly benefit health care

C. two researchers are discussing their patent with companies

D. researchers discover a molecule that can kill tooth decay-causing bacteria

Children in the United States eat too much pizza that some researchers now argue the food should join the ranks of sugary drinks and fast food for the harm they do to health.

In a new study, the researchers found that pizza is a large source of calories, saturated fat(饱和脂肪)and salt in children’s diets.Children should not eat more than two slices of pizza for a meal.and should pair that with salad, rather than with another high-calorie food,the researchers concluded.

“Parents should aim to control pizza consumption(消费), particularly as a snack where it was shown to have a very adverse impact on children, and they should put their pizza dollars toward healthier brands.” said Lisa Powel, director of the Illinois Prevention Research Center.

Pizza has become a matter of focus in recent years for researchers who look at the meals children eat, rather than the nutrients within them.Studies have found pizza is among the greatest sources of calories for children.

“Since pizza remains a common part of children’s diet, we need to make ‘healthy’ pizza.”Powel said.To make pizza healthier, food producers should reduce its saturated fat and salt, and increase its whole grain content,she said.

Whether or not pizza is harmful enough to be picked out as an unhealthy food, the study attracts attention to a larger issue with the modern American lifestyle, said Alexis Tindall, who was not involved in the flow research.Many foods arc eaten too frequently and in large sizes.said Tindall.To solve the problem, people don’t have to give up eating pizza, but instead, they can eat smaller and healthier pizza,she said.

“Make it at home, instead of ordering it out where you don’t have any control over how it’s made.”Tindall said. “When we make it at home, we can choose healthier ingredients,increase the vegetables.reduce fat, and put in less cheese.Pizza doesn’t have to be just pepperoni(意大利辣香肠)and cheese.”

1.According to the research.children shouldn’t eat

A.more than two slices of pizza in a day

B.two slices of pizza for a meal

C.more pizza with French fries

D.pizza along with salad

2.Powel suggests healthier pizza should be made

A.with less salt B.with more ingredients

C.in smaller sizes D.at home

3.The last sentence of the passage implies that pepperoni and cheese

A.are not necessary ingredients of pizza

B.should be reduced by adding healthier ingredients.

C.should all be replaced with healthier ingredient.

D.are not the only healthy ingredients of pizza

4.What is the best title for the passage?

A.Pizza—a real junk food!

B.How to prepare better meals for your kids?

C.Bring in healthier pizza for Americans

D.Discover the harm of eating pizza
