Children whose parents live well into their 80s seem to have healthier hearts in middle age compared with children whose parents did not live this long. Moreover, the heart advantage continues over time, which should help them follow in their parents’ footsteps.
The findings come from the Framingham Heart Study, a study relating to several generations on risk factors for heart disease and other diseases among residents of
The worst Framingham Risk Scores a measure of heart disease risk that uses age, smoking, and blood pressure to estimate a person’s possibility of suffering a heart attack were found in children whose parents had both died before age 85. The best risk scores were found among children whose parents had both lived to age 85 or older.
“A greater understanding of the genetics of risk of heart or blood disease factors and long life may lead to advances in the prevention and treatment of heart and blood diseases in the future,” Dr. terry commented to Reuters Health.
Dr. Clyde B. Schechter adds in an editorial: “We are only beginning to learn about the factors of exceptional long life. Several fruitful areas are already the subject of active research, but much more remains to be done.”
“Progress in this area is not just of natural interest,” Schechter from Albert Einstein College of Medicine, Bronx, New York writes, “it also has the great possibility to promote discoveries that will improve the prevention and treatment of some age related diseases such as heart or blood diseases.”

President Obama's plan to improve former president George W. Bush's No Child Left Behind program is an improvement on a good thing. But it doesn't go far enough.
Obama outlined a goal that by 2020, all grade school and high school students are on a path toward college.
However, what we need is a practical plan that not only requires all high school graduates to take at least two years of college but also makes it financially possible for them to do so. We've provided a free public education through the 12th grade. If we're going to keep up—or catch up——with some other countries (like China) in preparing young people for careers, a 12-year education programme no longer is enough.
About 3 million students across the US will graduate from high school this spring. But only 2 million will go on to college, according to a survey by the National Centre for Education Statistics (NCFES). For the more than 1 million who won't go on, money is a main reason. If tuition(学费) were free, about half of them could make up other costs from family or part-time jobs.
Critics (批评家) of free college tuition will say we can't afford it because of the federal deficit (联邦赤字) and other rising costs. Let's see some government spending in detail:
In the last nearly 10 years, the wars in Iraq and Afghanistan have cost us $ 1,000 billion. Federal money which was spent on public primary and secondary education in the last year for which figures are available was $ 47 billion. If we end costly and unnecessary wars and nation-building efforts abroad, the federal government could provide more money on public education, for which state and governments now carry most of the burden.
What's the program No Child Left Behind about this year?
All children being taken good care of by the government.
All grade school and high school students receiving college education.
No child being left alone at home.
All children having good jobs in the future.
The author probably agrees that President Obama's plan ________.
has nothing to do with George W. Bush's program.
will surely succeed in ten years
is about 12-year education for all the children
doesn't contain practical measures(措施) to achieve its goal
If tuition were not paid for, about ________ American students could afford college education.
| A. 3 million | B. 2.5 million | C. 2 million | D. 1 million |
What can we learn from the passage?
The wars in Iraq and Afghanistan were necessary.
The federal government has enough money for the plan.
Critics of free tuition think highly of the plan.
Obama's plan might be difficult to carry out.

Imagine you’re at a party full of strangers. You’re nervous. Who are these people? How do you start a conversation? Fortunately, you’ve got a thing that sends out energy at tiny chips in everyone’s name tag (标签). The chips send back name, job, hobbies, and the time available for meeting-whatever. Making new friends becomes simple
This hasn’t quite happened in real life. But the world is already experiencing a revolution using RFID technology.
An RFID tag with a tiny chip can be fixed in a product, under your pet’s skin, even under your own skin. Passive RFID tags have no energy source-batteries because they do not need it. The energy comes from the reader, a scanning device, that sends out energy (for example, radio waves) that starts up the tag immediately.
Such a tag carries information specific to that object, and the data can be updated. Already, RFID technology is used for recognizing each car or truck on the road and it might appear in your passport. Doctors can put a tiny chip under the skin that will help locate and obtain a patient’s medical records. At a nightclub in Paris or in New York the same chip gets you into the VIP (very important person) section and pays for the bill with the wave of an arm.
Take a step back:10 or 12 years ago,you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The concept was that computer chips could be put everywhere and send information in a smart network that would make ordinary life simpler
RFID tags are a small part of this phenomenon. “The world is going to be a loosely coupled set of individual small devices, connected wirelessly,” predicts Dr.J.Reich. Human right supporters are nervous about the possibilities of such technology. It goes too far tracking school kids through RFID tags, they say. We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it. And how many beers. Accompanied by how many biscuits. w*w*When Marconi invented radio, he thought it would be used for ship-to-shore communication. Not for pop music. Who knows how RFID and related technologies will be used in the future. Here’s a wild guess: Not for buying milk.
1. The article is intended to______.
A. warn people of the possible risks in adopting RFID technology
B. explain the benefits brought about by RFID technology
C. convince people of the uses of RFID technology
D. predict the applications of RFID technology
2. We know from the passage that with the help of RFID tags, people .
A. will have no trouble getting data about others
B. will have more energy for conversation
C. will have more time to make friends
D. won’t feel shy at parties any longer
3. Passive RFID tags chiefly consist of .
A. scanning devices B. radio waves C. batteries D. chips
4. Why are some people worried about RFID technology?
A. Because children will be tracked by strangers.
B. Because market competition will become more fierce.
C. Because their private lives will be greatly affected.
D. Because customers will be forced to buy more products.
5. The last paragraph implies that RFID technology .
A. will not be used for such matters as buying milk
B. will be widely used, including for buying milk
C. will be limited to communication uses
D. will probably be used for pop music

阅读表达。(共5小题；每小题2分，共10分。)
Counterfeit (假的) medicines are a widespread problem in developing countries. Like other counterfeits, they look like real products. But counterfeit drugs may contain too little or none of the active ingredients (原料) of the real thing.
People do not get the medicine they need. And in some cases the counterfeits cause death. Twenty children in Bangladesh died last year after being given acetaminophen (醋氨粉). The medications contained ingredients that looked, smelled and tasted like the real thing. The medicine was produced by a local drug company that used a dangerous substitute to save money.
The problem with counterfeit medicines is especially bad in Africa, Asia and Latin America. The W. H. O. estimates that up to thirty percent of the medicines on sale in many of those countries are counterfeit. . The W. H. O. says counterfeits make up less than one percent of the illegal drug market in countries like the United States, Canada, Japan, and New Zealand.
But the agency also says as much as fifty percent of the medicine sold on the Internet is counterfeit.
Much is being done to fight counterfeit drugs. Several companies are developing ways to make counterfeits easier to identify. And there are existing methods, like a machine that can quickly identify chemicals in pills to confirm if the pills are real. Other ideas include things like special tracking codes for drug packages. People could send a text message with the code and get a message back proving that what they bought is listed in a database. Some drug makers and other companies put three-dimensional images called holograms (条形码) on their products as a security device.
1. What advice can we get from Paragraph 4? (no more than 8words)
2. What is the main idea of the last paragraph? (no more than 10 words)
3. Complete the following statement with proper words. (no more that 4 words)
A local drug company produced counterfeit medicines by using dangerous substitutes .
4. Fill in the blank in Paragraph 3 with a proper sentence. (no more than 10 words)
5. What does the underlined word “they” in Paragraph 1 refer to? (no more than 3 words)
