The effects of coffee consumption on health have long been a subject of conflict and uncertainty. Since the 1980s, some have spoken out against coffee as it’s harmful to health, while others have welcomed coffee for its supposed benefits to health.According to a scientific report, mild coffee consumption, three to five cups per day, can be taken as a healthy dietary pattern, along with other healthful behavior. The report also says that coffee consumption helps reduce the risk of heart disease and it protects against Parkinson’s disease.According to Dr. Donald Hensrud of Mayo Clinic, high consumption of coffee has health risks. Dr. Hensrud mentions the dangers of high coffee consumption for people with a certain illness that slows the breakdown of caffeine in the body. Some studies said that drinking two or more cups of coffee daily can actually increase the risk of heart disease in these people.According to conclusions from a recent study led by Dr. Gregory Marcus, a doctor from the University of California, San Francisco, daily moderate consumption of caffeine, less than 4 cups, is not associated with these issues.Until the scientific community reaches a general agreement on the effects of coffee consumption on human health, it will be up to the individual to decide whether the benefits of drinking coffee are greater than the risks.When informed of these possible health benefits and harm of drinking coffee, Harwood, a high school student stated, “Even though there might be some negative effects of drinking coffee, for the most part, coffee drinking sounds good for health. Not to mention I need coffee to stay awake.”【解题导语】本文是一篇说明文。

One of the main creators of the World Wide Web，Sir Tim BernersLee has warned that the fast growth of the Internet is also creating serious problems.He especially warns of false information being easily spread around the Internet，“A great danger is that it becomes a place where untruths start to spread more than truths，or it becomes a place which becomes increasingly unfair in some way.”In particular he mentions the p henomena of blogging.Blogging enables friends and contacts to easily spread information.However he argues that people may too easily trust information mentioned in a blog.This inaccurate information can then easily become an accepted truth on the Internet.He suggests that the most important development of the Internet will be in creating ways of allowing people to check the correctness of information by providing original sources.Sir Tim admits that this is an important challenge.It's interesting to note that Wikipedia(维基百科)has had to take steps to prevent false information from being added to the biographies of living people.It's easy for anybody to edit the open source.However，some people have pointed out that it has been used to spread false materials.In seeking to raise standards，Wikipedia has sought to stop the false materials.At the same time there is a growing view that the Internet has had a great effect on the way millions of people work.The last two years have seen a big growth in the use of the Internet.There appears no slowdown in the growth of the Internet with increasing access in the developing countries.Sir Tim says another major challenge will be to provide free Internet for everybody.Sir Tim has recently launched a new joint initiative (倡议)between the University of Southampton and the Massachusetts Institute of Technology to create the first degree in Web science.The two schools hope to raise the standards of web content.1．What is the especially serious problem that Sir Tim refers to?A．The growth of the Internet is too fast.B．The Internet has a side effect on young children.C．The Internet companies compete against each other in an unfair way.D．The false information spreads rapidly on the Internet.2．What causes the biographies to have false information?A．The Internet users refuses other users to correct them.B．Wikipedia doesn't take any steps.C．Anybody can easily edit the biographies.D．Wikipedia attempts to publish false materials.3．According to the last paragraph，the purpose of the joint initiative is to ________.A．provide free Internet access to the poor countriesB．improve the reliability of online contentC．create the first degree in science and technologyD．enlarge the use of the Internet4．We can infer from the text that ________.A．Sir Tim has built two schools recentlyB．the Internet is harmful to the people's healthC．Sir Tim hopes everyone can use the Internet for freeD．the Internet develops slowly in the developing countries【解题导语】本文是一篇说明文，主要讲述了互联网的快速发展所带来的一些问题。

a discussion I had with my brother in our tiny bedroom in the family house in Bethlehem,Pennsylvania.We had heard in school about a planet called Pluto.It was the farthest,coldest,and darkest thing a child could imagine.We guessed how long it would take to die if we stood on the surface of such a frozen place wearing only the clothes we had on.We tried to figure out how much colder Pluto was than the Antarctic,or than the coldest day we had ever experienced in Pennsylvania.Pluto,which famously was downgraded from a “major planet” to a “dwarf planet”(矮行星)in 2006,captured our imagination because it was a mystery that could complete our picture of what it was like at the most remote corners of our solarsystem.Pluto’s underdog discovery story is part of what makes it so attractive.Clyde Tombaugh was a Kansas farm boy who built telescopes out of spare auto parts,old farm equipment and self-ground lenses.As an assistant at Lowell Observatory in Flagstaff,Arizona,Tombaugh’s task was to search millions of stars for a moving point of light,a planet that the observatory’s founder thought existed beyond the orbit of Neptune.On February 18,1930,Tombaugh found it.Pluto was the first planet discovered by an American,and represented a moment of light in the midst of the Great Depression’s dark encroachment (入侵).Pluto is much more than something that is not a planet.It’s a reminder that there are many worlds out there beyond our own and that the sky isn’t the limit at all.We don’t know what kinds of fantastic variations on a theme nature is capable of making until we get there to look.1.Why did Pluto become famous in 2006 according to the passage?A.Because it disappeared in the sky.B.Because it lost its major planet status.C.Because it was discovered by an American.D.Because it was proved to be the coldest planet in the universe.2.What can be a suitable title for the text?A.Pluto’s RomanceB.Pluto Was First Discovered by a BoyC.An American Scientist:Clyde TombaughD.The Days I Spent with My Brother in Pennsylvania3.What can we learn from the fourth paragraph?A.Clyde Tombaugh discovered the darkness in the Great Depression.B.Pluto was the only planet that was discovered by Clyde Tombaugh.C.Clyde Tombaugh’s telescopes used for searching stars were very simple.D.Clyde Tombaugh’s job was to build telescopes for Lowell Observatory.4.The underlined sentence in the last paragraph is most likely to mean .A.Pluto is no less than a planet in the solar systemB.Pluto is much more than a planet in the solar systemC.Pluto is more important than any other planet in the skyD.Pluto is not a planet in the solar system,but it is more than a planetBFollowing the crowd may not always be in a person's best interest.But new research suggests that teens who get along with their friends may end up healthier as adults.Scientists have known that close friendships help boost health.That's true for both teens and adults.The finding inspired Joseph Allen，a psychologist at the University of Virginia，and his team to study whether experiences during teen years would influence adult health.So they followed 171 teens，starting when the kids were just 13.They interviewed each one every year for five years，and also spoke to these teens' closest friends，who provided additional information about the quality of their friendships.The same 171 people were interviewed again at ages 25,26 and 27.This time, the questions surveyed each person's overall health.When the researchers analyzed the data，they found a strong connection between a teen's behavior and adult health.Teens who had close friends grew up to be the healthier adults.Whether teens held back their feelings or expressed them to close friends also influenced later health.Those who held back their feelings were more likely to be sick as adults.The connection held up even after the scientists accounted for other possible influences on health.Weight，family income and drug use were all examined.So were mental health issues，such as anxiety and depression.And in these people，such other factors did not explain adult health as well as teen friendships did.Getting along with the crowd may have benefits，says Allen，but there are also drawbacks.Teens who are more independent tend to do better at school and work.And peer pressure may lead some kids to engage in risky behavior，such as smoking，drinking or using drugs.Dealing with it is an ongoing challenge，Allen acknowledges.“Finding the right balance is the key.Teens shouldn't lose heart for not finding this easy.”And，he adds，“Parents need to be understanding about the pressures teens face.”1．Where can you probably read this passage?A．Science fiction.B．Health column.C．Fashion magazine.D．Entertainment newspaper.2．We can learn from Allen's study that ________.A．many other factors have a greater influence on adult health than teen friendships B．mental health issues have nothing to do with adult healthC．the same 171 teens were interviewed each year from 13 to 27D．the teens who couldn't express themselves grew up to be unhealthy3．According to what Allen said，we can know that ________.A．in order to do better at school，teens should not follow the crowdB．though it's challenging for teens to deal with peer pressure，they should not give upC．teens will engage in smoking，drinking or using drugs when facing peer pressure D．parents should understand their teens and stop them going with friends 4．What can be inferred from the passage?A．There is nothing bad for teens to follow the crowd.B．Close friendships are the most important for people's health.C．Teen friendships may help teens become healthier adults.D．Adult health is only influenced by teen friendships.【解题导语】研究表明，与朋友较少或者没有朋友的青少年相比，有朋友的青少年在长大后更健康。
