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

Even before my father left us, my mother had to go back to work to support our family. Once I came out of the kitchen, complaining, “ Mum, I can’t peel potatoes. I have only one hand.”
Mum never looked up from sewing. “ You get yourself into that kitchen and peel those potatoes,” she told me. “ And don’t ever use that as an excuse for anything again!”
In the second grade, our teacher lined up my class on the playground and had each of us race across the monkey bars, swinging from one high steel rod to the next. When it was my turn, I shook my head. Some kids behind me laughed, and I went home crying.
That night I told Mum about it. She hugged me, and I saw her “we’ll see about that” look. The next afternoon, she took me back to school. At the deserted playground, mum looked carefully at the bars.
“ Now, pull up with your right arm,” she advised. She stood by as I struggled to lift myself with my right hand until I could hook the bar with my other elbow. Day after day we practiced, and she praised me for every rung I reached.
I’ll never forget the next time, crossing the rungs; I looked down at the kids who were standing with their mouths open.
One night, after a dance at my new junior high, I lay in bed sobbing. I could hear Mum came into my room. “ Mum,” I said, weeping, “ None of the boys would dance with me.”
For a long time, I didn’t hear anything. Then she said, “Oh, honey, someday you’ll be beating those boys off with a bat.” Her voice was faint and cracking. I peeked out from my covers to see tears running down her cheeks. Then I knew how much she suffered on my behalf. She had never let me see her tears.
1.Which of the following expressions can be used most suitably to describe Mum’s attitude when she made the child peel potatoes?
A. Cruel B. Serious
C. Strict D. Cold
2. What does the underlined sentence in Paragraph 4 imply?
A. Mum believed every aim could be achieved if you stuck to it.
B. The race across monkey bars was not difficult enough for a child to give up.
C. Mum was determined to prove she herself was better than the teacher.
D. What the child had said brought Mum great attraction and curiosity.
3.When the child looked down at the kids, they were standing with their mouths open because ______.
A. they felt sorry for what they had done before.
B. they were afraid the author might fall off and get hurt.
C. they wanted to see what the author would do on the bars.
D. they were astonished to find the author’s progress.
4.The most probable conclusion we can draw after reading the passage is ____.
A. the last incident was sad enough to make Mum weep
B. the child’s experience reminded Mum of that of her own
C. Mum could solve any problem except the one in the last paragraph
D. Mum suffered more in the process of the child’s growth actually

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．
1.What do we learn about Facebook from the first paragraph？
A．It is a website that sends messages to targeted users
B．It makes money by putting on advertisements
C．It earns money by selling its user’s personal data
D．It provides a lot of information to its users
2.What does the author say about most Facebook users？
A．They don’t know their personal data enriches Facebook
B．They are unwilling to give up their personal information
C．They don’t identify themselves when using website
D．They care very little about their personal information
3.Why does Facebook make changes to its rules according to Elliot Schrage？
A．To help its users make more friends
B．To obey the Federal guidelines
C．To make money by attracting more users
D．To offer better service to its users
4.What does Senator Charles Schumer argue for？
A．Setting guidelines for advertising on websites
B．Setting rules for social-networking sites
C．Stopping sharing user’s personal information
D．Removing ads from all social-networking sites
5.Why does the author plan to stop using his Facebook account？
A．He is dissatisfied with its service
B．He finds many of its users untrustworthy
C．He doesn’t want his personal data abused
D．He is upset by its frequent rule changes
