1、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was -91℃ which occurred in Antarctica in 1983.We encounter an interesting situation when we discuss temperatures in space Temperatures in Earth orbit actually range from about +120℃ to -120℃. The temperature depends upon whether you are in direct sunlight or shade, Obviously, -120℃ is colder than our body can safely endure. Thank NASA science for well-designed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our area of the solar system . Obviously, it is hotter closer to the Sun and colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about -210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is -273℃, at which atoms do not move. Two scientists, whose names are Cornell and Wieman, have successfully cooled down a gas temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 for their work not a discovery in this car.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about particles we now call photons. Bose had trouble convincing Other scientists to believe _____ he contacted Albert Einstein. Einstein\'s calculations helped him theorize would behave as Bose thought but only at very cold temperatures.Scientists have also discovered that ultra-cold atoms can help them make the world\'s atomic clocks even more accurate. These clocks are so accurate today they would only lose one second every six million years! Such accuracy will help us travel in space because distance is velocity times time(d=vxt). With the long distances involved in space travel to know time as accurately as possible to get accurate distance.【单选题】

3、Desirable Qualities in a TeacherHere I want to try to give you an answer to the question: What personal qualities are desirable in a teacher? Probably no two people would draw up exactly similar lists, but I think the following would be generally accepted.First, the teacher\'s personality should be pleasantly live and attractive. This does not rule out people who are physically plain, or even ugly, because many _____ have great personal charm. I would say that excludes all of dull or purely negative personality. I still stick to what I said in my earlier book: that school children probably suffer more from bores than from brutes.Secondly, it is not merely desirable but essential for a teacher to have a great capacity for sympathy in the literal meaning of that word; a capacity to tune in to the minds and feelings of other people, especially, since most teachers are school teachers, to the minds and feelings of children. Closely related with this is the capacity to be tolerant not indeed, of what is wrong, but of frailty （脆弱) and immaturity of human nature which induce people, and again especially children, to make mistakes.Thirdly, I hold it essential for a teacher to be both intellectually and morally honest. This does not mean being a plaster saint. It means that he will be aware of his intellectual strengths.【单选题】

A.people

B.ones

C.such

D.those

正确答案:C

答案解析:此句意为“这并不排除长相平平，甚至面貌丑陋者，他们或许更有魅力”，many such指“很多这样的人”。

4、Why People Use Pseudonyms (假名字)?You can\'t choose the name you are given at birth, but in many countries you can change it legally when you reach adulthood. Of course, most people never change their names even if they feel unhappy about them. However some people do take this course of action－particularly artists! What makes an artist want to change their name? Sometimes it\'s for purely personal reasons, such as the Nobel Prize winning poet from Chile, Neftalf Reyes. He didn\'t want his father to know he was writing poetry, so he changed his name to Pablo Neruda when he was a young man. At other times the reason may appear strange, take the case of the Portuguese poet Femando Pessoa, who wrote under 75 different names. The reason? "When I use a different name, I always write in a different way," he explained. In most cases, however , people change their names for social, historical, political, or cultural reasons. Here are some of the most common: reason. The person\'s real name is just too long and difficult to remember. Let\'s be honest, Madonna Louise Ciccone is not as easy to remember as just plain Madonna. And short names are much easier to remember: William Bradley became Brad Pitt and Edson Arantes do Nascimento became Pele.Sometimes names are changed for marketing purposes. For example, if a name sounds too foreign, it may be changed to something that is more recognizable in a market. So in the film world, Ramon Estsvez adopted the name Martin Sheen. Or maybe the artist\'s real name doesn\'t sound attractive－Chad Everett does sound a lot better than Raymond Cramton.Artists sometimes choose the name of someone they admire. Robert Zimmerman changed his name to Boo Dylan because of his admiration for the Welsh poet, Dylan Thomas.Another reason may be practical: in the past, women found it very difficult to get published. To ____ this situation, they sometimes gave themselves men\'s names, so the English author Mary Ann Evans became George Eliot, and she did get her books published!【单选题】

A.admit

B.avoid

C.assure

D.affect

正确答案:B

答案解析:本题难度不大，根据文中句意，此处要选择“避免”的意思，所以最佳答案是B。

5、Money or Friendship or Both1. Friends and money don\'t mix. It\'s a dangerous combination since a fight over money is one of the fastest ways to end a friendship. But what if a friend asks you to tend him or her some money? If you don\'t lend your friend the money, you risk losing the friend. If you do lend your friend the money, you risk losing both the friendship and your money.2. We have to face facts, so here are some situations you might run across with your buddies (伙伴) and some helpful tips (忠告) on how to deal with them. Thinking about why this person needs to borrow in the first place. If he is always living beyond his means, it is his fault, not yours. Any Sensible person would not put himself in a position of debt so often. So simply say "no" to this friend. Even if your friend really needs that money for emergency use and you are willing to help him, before you dive into your pocket, follow this reality check: Do you have the extra money? Are you sure you don\'t need it? Are you willing to write off that amount if it\'s not returned? If your answers are negative, do yourself a favor and say "no".3. Let\'s assume you can\'t stand saying "no" to your friend because you don\'t want him living off cat food. What do you do? Write down these details on a sheet of paper before opening up your wallet:Amount of the loan.Date of the loan.Time of repayment.Amount of interest (if any).Lender\'s and borrower\'s signature.This will at least keep the borrower from forgetting the loan so easily, If your friend\'s loan is past due, it\'s important that you ask him－and it\'s actually not rude. The longer you wait, the more you are brood (忧伤), and the more your resentment builds.4. You can send him a friendly reminder via E - mail. Tell him something like "I\'m going over my bank account and I\'m just wondering when we\'ll be able to settle that money thing." E - mail saves you from an uncomfortable face - to - face confrontation. There is almost no chance of turning a bad reaction into an argument. Unlike a public conversation, an E - mail message will always be private.5. After asking two or three times, you might have to write it off. That\'s what happens. If he just doesn\'t have the money or is unwilling, then what kind of friend is that?Paragraph 2 ____【单选题】

A.Time to Break off a Friendship

B.Unconditional Assistance to Friends in Need

C.Things to Consider When You Have to Say "No" to Your Friend

D.Things to Think over When You Don\'t Want Your Friend to Eat Cat Food

E.Strategies for Borrowing Money

F.Advantages of E - mail in Handling Money Issues

正确答案:C

答案解析:本题难度不大，主旨句比较好确认，就是第二段的第一句，谈到我们必须面对事实，当你在某些情况下遇到你朋友跟你借钱时，下面有几条忠告来帮助你应对这种状况。换句话说第二段主要给出了如何对朋友说“不”的几条忠告。回来看选项，比较明显，C项Things to Consider When You Have to Say "No" to Your Friend，就是对本段的概括，所以答案是C。
