This month, the singing competition, American Idol, will come to an end. For years, the popular show was a platform for rising artists. With a group of famous judges and a wide range of talents, it is clear that the competitive atmosphere of American Idol will remain unrivaled by any other show. After all, its success has been ＂unmatched in broadcasting history.＂American Idol came from the British series Pop Idol. Through an application, contestants came into the competition and thereafter, were chosen to audition(试音)for the show. Each candidate would have to perform a piece to the judges, and participate in a strict selection process. Not only would contestants have to sing in groups, they were sometimes tasked to perform pieces without musical instruments. At the end of this stage, only 24 o 36 artists were chosen to enter the semi-final stage. Soon, the fate of the contestants would be decided by the public. During the candidate’s live performance, a free telephone number was displayed on the screen for viewers to dial, to cast their vote. At the end of the night, only 13 lucky singers would be left in the competition; by the finals, only 8 contestants would remain. Finally, a runner-up(亚军)and a winner were announced every season. Though only the winner would receive a million dollar reward and a significant record deal, other contestants would have had a chance to be known by the public. As the famous producer Simon Cowell once said, ＂The point of the show is not to be mean to loser, but to find a winner.＂ As the final season of the program begins, past winners will return to the stage to say goodbye and a new winner will be announced. With amazing performances and an excellent cast of singers, the show’s conclusion will leave audiences nostalgic(怀旧的), but more satisfied than ever.1. Those who enter American Idol will _______.A. share the one million dollar reward togetherB. be asked to perform in pairs in the semi-finalsC. experience at least three rounds of performancesD. have the chance to become famous even if they fail2. Who play the most important roles in the finals of American Idol?A. The audiencesB. The past winnersC. The judgesD. The record companies3. The author thinks the conclusion of American Idol will _________.A. change its historyB. be worth watchingC. not be the last seasonD. pick her favorite singer4. In which section of the newspaper may you probably find the passage?A. AdvertisementB. FinanceC. EntertainmentD. Business【语篇解读】本文为说明文，介绍了很受欢迎的流行节目American Idol和它的比赛过程。

The Internet plays a big part in human life. We use it for work and entertainment. We can find new recipes on the Internet or advice on staying healthy. We can even use it to learn a new language. We use the Internet to connect with family and friends and stay in touch with issues we care about.The list goes on and on.As far as the Internet being a part of our lives—well, that train has left the station. That expression means there is no going back. If you prefer boating, you can say that ship has sailed.So, there may be no going back to an Internet-free life. But can using the Internet too much be bad for our health?It might be, say researchers.Study results show that teens who spend at least 14 hours a week online were more likely to have high blood pressure.High blood pressure makes your heart and blood vessels work too hard. Over time, this extra strain increases your risk of a heart attack or stroke.High blood pressure can also cause heart and kidney disease. It is also closely linked to some forms of dementia, a brain disease. Dementia is marked by memory disorders, personality changes, and a reduced ability to reason.Let’s introduce something about the study of it.The Henry Ford Hospital in Detroit, Michigan did the study. It involved 335 young people, from 14 to 17 years old. One hundred thirty-four of the teens were described as “heavy Internet users”. Researchers found that out of these 134 teens, 26 had high blood pressure.The researchers say the study is the first to connect heavy web use and high blood pressure. Other research has connected that heavy Internet use with health problems including anxiety, depression and obesity.The lead researcher of the study is Andrea Cassidy-Bushrow. In a statement she said, “Using the Internet is part of our daily life but it shouldn’t consume us. ”For the purpose of the study, she explains, teens considered heavy Internet users were online on “average 25 hours a week. ”Ms Cassidy-Bushrow adds that it is important for teens to take “regular breaks from their computers or smartphones” and to do some “kind of physical activity. ”She also suggests that parents limit their children’s use of the Internet to two hours a day, five days a week.【文章大意】互联网如此有用并且融入我们的生活, 但过度使用它, 会导致多种健康问题。

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。

Life can be so wonderful, full of adventure and joy. It can also be full of challenges, setbacks(挫折) and heartbreaks. Whatever our circumstances, we generally still have dreams, hopes and desires that little something more we want for ourselves and our loved ones. Yet knowing we can have more can also create a problem, because when we go to change the way we do things, up come the old patterns and pitfalls(陷阱) that stopped us from seeking what we wanted in the first place.This tension between what we feel we can have and what we’re seemingly able to have is the niggling(烦人的)suffering, the anxiety we feel. This is where we usually think it’s easier to just give up. But we’re never meant to let go of part of us that knows we can have more. The intelligence behind that knowing is us — the real us. It’s the part that believes in the life and its possibilities. If you drop that, you begin to feel a little ＂dead＂ inside because you’re dropping ＂you＂.So, if we have this capability but somehow life seems to keep us stuck，how do we break these patterns?Decide on a new course and make one decision at a time. This is good advice for a new adventure or just getting through today’s challenges.While, deep down, we know we can do it, our mind — or the minds of those close to us — usually says we can’t. That isn’t a reason to stop, it’s just the mind, that little man or woman on your shoulder, trying to talk you out of something again. It has done it many times before. It’s all about starting simple and doing it now.Decide and act before overthinking. When you do this you may feel a little, or large, release from the jail of your mind and you’ll be on your way.1. It can be inferred from the first two paragraphs that we should ________.A. slow down and live a simple lifeB. be careful when we choose to changeC. stick to our dreams under any circumstancesD. be content with what we already have2. What is the key to breaking the old patterns?A. To focus on every detail.B. To decide and take immediate action.C. To listen to those close to us.D. To think twice before we act.3. Which of the following best explains the underlined part in the last paragraph?A. Escape from your punishment.B. Realization of your dreams.C. Freedom from your tension.D. Reduction of your expectations.4. What does the author intend to tell us?A. It’s easier than we think to get what we want.B. It’s important to learn to accept sufferings in life.C. It’s impractical to change our way of thinking.D. It’s harder than we expect to follow a new course.【文章大意】本文是一篇议论文。

One of the main creators of the World Wide Web，Sir Tim Berners.Lee 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 phenomena of blogging。

Unit 4 Astronomy the science of the starsⅠ阅读理解Got big plans for Friday night? That’s OK, we don’t either.Guess we’ll all have to make do by watching the celestial(天空的) show that will take place that night.First, there will be a full moon. That’s always fun, but this one will be a little more special. It’s known as a “snow moon”. The name es from the fact that the heaviest snows usually fall during February, according to The Old Farmer’s Almanac.But if that’s not special enough, there’s also an eclipse(月食) that night. It’ll be a penumbral lunar eclipse, meaning it’s a partial eclipse that leaves sections of the moon darkened by the earth’s shadow. No, it won’t be as spectacular as those “blood moon” eclipses. It’ll be subtler. The level of darkness it reaches during the eclipse may or may not be apparent；it just depends on where you are when you view it.In North America, the eclipse begins at 5：34 p．m. ET and ends at 9：53 p．m. ET, according to the astronomy website EarthSky. The eclipse will be at its height around 7：44 p．m. ET.If that’s still not enough, let’s throw in a et(彗星) to the night’s festivities.et 45P (it has a much longer name, but we won’t burden you with it here) is visible as it flies by the earth. The et will get within 7.4 million miles of the planet as it makes its closest approach this weekend, according to Universe Today.et 45P will be most visible a couple of hours after the eclipse, so look to the skies again around 3 a．m. ET Saturday and find the greenish­blue light with a tail.And don’t forget, a total big­time solar eclipse will streak across the United States on August 21st.【解题导语】本文是说明文，介绍了星期五晚上将会发生的天文现象。
