阅读理解

    A scientist once said: "I have concluded that the earth is being visited by intelligently controlled vehicles from outer space."

    If we take this as a reasonable explanation for UFOs (unidentified flying objects), questions immediately come up.

    "Why don't they get in touch with us, then? Why don't they land right on the White House lawn and declare themselves?" people asked.

In reply, scientists say that, while this may be what we want, it may not necessarily be what they want.

    "The most likely explanation, it seems to me," said Dr. Mead, "is that they are simply watching what we are up to—that responsible society outside our solar system is keeping an eye on us to see that we don't cause a chain reaction that might have unexpected effects for the outside of our solar system."

    Opinions from other scientists might go like this: "Why should they want to get in touch with us? We may feel we're more important than we really are! They may want to observe us only and not interfere(干涉) with the development of our civilization. They may not care if we see them but they also may not care to say 'hello'."

    Some scientists have also suggested that Earth is a kind of zoo or wildlife reserve. Just as we set aside wilderness areas and wildlife reserves to allow animals and growing things to develop naturally while we observe them. So perhaps Earth was set aside ages ago for the same purpose.

    Are we being observed by intelligent beings from other civilizations in the universe? Are they watching our progress in space travel? Do we live in a huge "zoo" observed by our "keepers," but having no communication with them?

    Never before in our history have we had to face ideas bravely like these. The simple fact is that we, who have always regarded ourselves as supreme in the universe, may not be so. Now we have to recognize that, among the stars in the heavens, there may very well be worlds lived by beings who are to us as we are to ants.

(1)、People who ask the question "Why don't they get in touch with us then?" think that ________.
A、there are no such things as UFOs B、UFOs are visitors from solar system C、there's no reason for UFOs to contact us D、we are bound to see UFOs sooner or later
(2)、According to Dr. Mead, the beings from outer space ________.
A、hope to keep in touch with us B、want to keep watch on us C、try to protect us from dangers D、get ready to help others
(3)、What's the writer's attitude towards the existence of other intelligent beings in space?
A、Doubtful. B、Neutral. C、Negative. D、Positive.
(4)、The passage is mostly taken from a(n) ________.
A、commercial advertisement B、science fiction novel C、newspaper column D、travel leaflet

    “Success begins with belief and ends with doubt.”—Larina Kase

    I remember reading through a book and the author was writing about being a reverse paranoid. In that particular section he mentions how he has a belief that the world he's living in is out to give him everything he absolutely wants and desires.

    There are times when I think to myself,“Wow,the world is out to get me and make me miserable.” Then I thought,why can't I believe that the world is out to make me a better conversationalist. Then I started adapting to the belief of the reverse paranoia.

    When I started talking to people,I truly believed that I was the most interesting person in the room. I believed that everything I said added value to the conversation. I believed that people stayed behind and chatted with me because they found me charismatic.

    As a matter of fact, for about five months I wrote down on my bathroom mirror the following affirmation:“People love me and respect me. It is a privilege to talk to me. People find me interesting and charming and always want to get to know me better!”

    I would say the affirmation after I brushed my teeth. And I would continue to say it until I felt completely great about myself. There were days that I just wouldn't feel like saying it,because it would feel like a lie to me. But that's the trouble,like the quote says,success ends when there's doubt. And that's why I continued until I had no doubt in my mind.

    Then strange things happened,I noticed that people did find me more interesting,and that I gained more confidence in talking with people. I was more assertive(坚定自信的) at work. I was able to control politics and gossip at work to minimal levels,and became a much better manager,and developed better customer relations to the point that sales were up by 20% compared to the year before,on my best month sales were up by 39%,and this was a year that a recession was happening.

    One of the most important things in the world is friendship. In order to have friends, you have to be a friend. But how can you be a good friend at school?

    Listen — Listen when they are talking. Don't say anything unless they ask you a question. Sometimes it's not necessary for you to have anything to say; they just need someone to talk to about their feelings.

    Help them — If your friend is ever in need of something, be there to help them. You should try to put them first, but make sure you don't do everything they want you to do. Try to take an extra (额外的) pencil or pen with you to classes in case (以防) they forget one. Have a little extra money in your pocket in case they forget something they need.

    Be there for them — Try to make something for your friend to help make them feel better in hard times. Making cards and encouraging them are among the nicest things you can do for a friend. Marilyn Monroe, a famous U.S. actor, once said, “I often make mistakes. Sometimes I am out of control. But if you can't stay with me at my worst, you are sure not to deserve (值得) to be with me at my best.” Always remember this! If you don't want to stay with your friends when they're in hard times, then you don't deserve to be with them when they're having a good time!

    Try to make plans with your friends. Go shopping, go for ice cream, have a party, go to a movie and so on. Take time to know each other even better by doing something you both enjoy. By planning things together, you both can have a good time. And you'll remember these things when you're all old!

    There might be as many as 10 million species of complex life on this planet today —— a huge number. But add up all of the complex species that ever lived and some biologists think the grand total would be about five billion. The estimate leads to an astonishing conclusion: a staggering 99% of species are not around any more. They have been driven to extinction.

    More species are joining the ranks of the extinct every year. Many scientists believe we are living through an episode of remarkably rapid extinction, on a scale that has been seen only five times in the last half a billion years.

    They call this current episode the sixth mass extinction —— a large, global decline in a wide variety of species over a relatively short period of time. And they tend to agree that humans are the main cause.

    Over-hunting, overfishing, and human-driven habitat loss are pushing many species to the brink. In fact, we have changed the planet so much that some geologists are now suggesting that we have entered a new phase in Earth's history; an epoch they call the "Anthropocene". By 2100, it is expected that humans will have caused the extinction of up to half of the world's current species.

    Because we are living through this extinction, it is relatively easy for us to study the driving forces behind it. But how do we determine what caused other mass die-offs that happened long ago? To do so we have to look at what archaeologists, palaeontologists, geologists and other scientists have concluded from the evidence they have gathered.

    The trouble is, those scientists do not always agree with one another —— even about the most recent extinction event. As well as the five-or six- mass extinctions, there have also been many smaller extinctions.

    One of these mini extinction events happened towards the end of the Pleistocene, a few tens of thousands of years ago. It is sometimes called the "megafaunal" extinction because many of the species it claimed were particularly large animals, weighing more than 97lb (44kg). However, its cause remains a debate amongst scientists.

    It's a warm summer afternoon. You're cooking up the catch of the day over a campfire. Suddenly, a few raindrops fall on your arms, and before you know it, the sky is opened up. Then you hear what sounds like thunder in the distance. What should you do? Your tent is close by and would offer shelter from the pouring rain. There's a campsite picnic shelter a few minutes down the path. And then you remember that your car is parked down the road. What's your safest choice to make sure you and your families are safe?

    It's a common question for many hikers(徒步者) and campers, especially when they are camping during summer months. Heading to your car is almost always the safest choice. Your tent and a picnic shelter will keep you dry, but they offer little or no protection against lightening. Your car, on the other hand, will keep you dry and protect you from lightening strikes. Protecting yourself against possible lightening strikes is very important; lightening kills an average of 62 people in the US each year. If you keep all of the windows and doors closed in your car, you'll be able to return to your campsite safely.

    Of course, if you're backpacking(背包旅行), not car camping, and you're deep in the woods, your car won't be a good choice. So, what should you do if your car is far away and there's no other safe shelter nearby? First, you'll have to make sure that tree limbs or other objects don't fall on you or your campsite. Then you'll have to get in a safe position to avoid lightening, or flash flood conditions. What else should you do?

    Years ago, the American writer Kurt Vonnegut often said there was one story that would always make a million dollars: Cinderella.

    Cinderella made more like $ 70 million in ticket sales when it opened last weekend. But the movie got a mixed reaction. David Rooney of The Hollywood Reporter praised the movie and said, "Anyone will find something to enjoy in it." Steven Rea of The Philadelphia Inquirer called the movie "a winning re-do". Richard Corliss of Time magazine wrote that "Disney finally got Cinderella right." Other people were not as happy with the movie. Sara Stewart of the New York Post wrote, "This Cinderella is all dressed up with nowhere very interesting to go."

    Although different people think differently towards the movie, what is clear, however, is the movie's business success. It is not only popular in the theaters but also in sales. And Disney has widened its usual market for Cinderella products.

    There are products connected to the Disney movie targeted (面向) not only at little girls, but women, too. For example, the famous shoe designer Jimmy Choo worked with Disney to create Cinderella's shoes". You can buy them for about $ 5,000. At that price, you would not want to lose one at the party, even if that is the way you get your prince (王子).

    The make-up (化妆品) company MAC quickly sold all its products connected to Cinderella. HSN is a popular website selling clothing and objects for the home. The marketer is now also selling Cinderella products.

    So, is there anything left for the children, those people we think of as the traditional audience (观众) for the age-old tale? Yes, you can find toys and other children's products at the American store JCPenney. Of course, you can also visit a Disney store.

    It's 11 p.m., and I'm still sitting here writing this article for the school magazine! I've had two weeks to write it, and my teacher, Julia, wants it tomorrow. She's always complaining (抱怨) that I leave things till the last minute. Maybe she's right.

    A month ago I made a decision to be more efficient (有效率的) this year. Well, I've clearly failed. I've also been trying to get fitter for four weeks now. I've started going to the health club. I've even been going to bed earlier. But I'm not feeling any fitter, just a little unhappier. I miss my bad habits. Why is leading a better life so hard?

    I've just read an article on a website, and I've discovered that it isn't my fault (过错)! In fact, it isn't anyone's fault. It's our brain's. It's programmed to make it difficult to break bad habits. There's nothing we can do. Scientists have done experiments that show we use one part of our brain when we think about ourselves and another when we think about other people. However, when we think about ourselves in the future, we use the same part of the brain that we usually use to think about other people. In other words, the brain sees the “future you” as a different person than your “present you.” That's why we don't always find it easy to make good decisions for ourselves in the future.

    But that's not all. Scientists have also discovered that it takes around ten weeks to form a good habit. That's the amount (数量) of time the brain needs to accept new behavioral patterns (形式). The good news is that once you make it to ten weeks, everything becomes a lot easier. The bad news is that ten weeks is a really long time, so it's easy to give up what you want to do before then.

    So even when we want to change our ways and become better people, our brains won't let us. Or is this just an excuse? Look — I've finished my article on time! Anything is possible!
