He is very bright and aspiring and I enjoyed our conversation. Still I felt frustrated and useless afterwards because I was not able to provide him with any good news. Graduating at the end of this year, he asked me how he could find a job in this country and fulfill his career dreams. In recent years, students who found a job here after graduation have had to go through a cruel lottery system to obtain their H1B working visa.And the success rates have been declining year after year because of the ever growing number of applicants. Last year, there were 233，000 applicants, and only 30 percent of them were lucky，less than half of the rate in 2013. And it can only become worse.US President Donald Trump's immigration policies in this country are tightening up and this trend will continue for at least the next few years. In this case, foreign students studying social sciences, a field in which starting salaries are rarely above the required amount, can kiss their visa hopes goodbye. Compared to the older generation of Chinese students，today's young people no longer consider the US as the only option. Many start to think China offers better opportunities in the longer term. This is not to say that Chinese students in the US are not interested in job opportunities here any more.A few years of work experience in the US can give them leverage when they finally land back in their home country. But if the job opportunities are largely reduced by the tightening of immigration policy，I expect there will be a

AOf all the planets， none has captured the world's imaginationlike Mars。
Its reddish color and changes in brightness over time make the planet an unforgettable sight.In Cosmos, the television science series from the 1980s, scientist Carl Sagan talked about some traditional ideas about Mars。
Some of these ideas are from the English science fiction writer H．G.Well’s The War of the Worlds.Others are from the mistaken science of Percival Lowell， the American astronomer who believed intelligent beings lived on Mars。
Wells described Martians as threatening。
Lowell imagined them as the hopeful engineers of great works。
Carl Sagan said that both ideas influenced the public deeply.Today， Mars continues to excite humans - not as the object of science fiction but of scientific study.Space scientists have collected a wealth of information from spacecraft that have orbited, landed on and dug into the Martian surface。

He loved to travel, learning new things about different people and their culture.Roger was born and raised in Alabama, and he then moved to Buffalo, New York where he lived for many years until he relocated to Atlanta, Georgia, his final resting place.Whether his travels were long visits or short visits, in large cities or small towns, his favorite souvenir item was Tshirts.

Every Tshirt he owned had a story behind it that he would share with others.As long as he was laughing, living and traveling, he was happy. He loved everybody he came in contact with and everybody loved him. The old saying “He never met a stranger.” definitely applied to Roger and his life.His last few years of life were in hospital at least 1015 days a month, sometimes more. Two weeks before he passed away, I spoke with him on the phone, and even then he managed to tell jokes about life.I know he left this world happily; he refused to allow anything or anyone to hold him down, even his severe illnesses.

After the call, my whole body became feverish and panicky. The time from his call to the next morning seemed like years. The whole night, I could not sleep with many ominous apprehensions in mind. One of them was to call the principal with regret and tell him that I could not come. Finally, I gathered some courage. I thought, “If I miss this opportunity, surely the school will ne ver invite me again to any of their programs.”I reached the school in time. Before my turn came, my whole body was trembling. When my turn came and I started speaking, my heartbeat increased and my mouth went dry. I wasn’t even able to read the written speech properly. I was not aware of where I was standing and what I was reading. That was the day when I realized my biggest weakness, Public Speaking.After my speech, I met with the principal and explained what happened to me. He told me that this happens to everyone. Even great speaker, faced the same things when they started. He suggested that I come again next time.Around one month later, I was invited to refer to a topic on Motivation. This time I was feeling comfortable. My speech was not only appreciated by the principal as well as the teachers, because I was able to get my idea across to them. They encouraged and praised my efforts.After delivering successfully, I became more confident. I said to myself, “If I can speak in front of such a learned audience, like the principal who educates others, I can now speak in front of others too.”I started delivering lectures in my plan, on various topics like Self Motivation, Personality Development, Personal Excellence, Spoken English and Presentation Skills. This has become a passion for me. I learned that everything is possible if we have the courage to take the first step. 1.Why did the author have bad feelings before the speech?A.he feared he couldn't perform it properly.B.he had got a high fever before thatC.he regretted accepting the invitationD.he disliked the idea of giving a lecture2.What does the underlined part “ominous apprehensions” in the first paragraph mean?A.Unlucky opportunities.B.Curious views.C.Negative ideas.D.Happy comments.3.What can we conclude from the passage?A.Necessity is the mother of invention.B.Nothing is to be got without pains but poverty.C.Knowledge makes humble, ignorance makes proud.D.A journey of a thousand miles begins with a single step.4.Which of the following is the best title for the passage?A.Public Speaking Makes a Man Embarrassed.B.Principal Provides the Best Chances.C.Practice Makes a Man a Better SpeechmakerD.Spoken English Develops in Speeches.3、In mice, scientists have used a variety of drugs to treat brain disorders including murine versions of Alzheimer’s disease(阿尔茨海默氏病）and depression. But in people, these same treatments usually fail. And now researchers are beginning to understand why. A detailed comparison of the cell types in mouse and human brain tissue found subtle but important differences that could affect the response to many drugs, a team reported on Wednesday.“If you want to develop a drug that targets a specific receptor in a specific disease, then these dif ferences really matter,” says Christof Koch, an author of the study and chief scientist and president of the Allen Institute for Brain Science in Seattle.One key difference involved genes that cause a cell to respond to the chemical messenger serotonin (血淸素), says Ed Lein, a study author and investigator at the institute. “They’re expressed in both mouse and human，but they’re not in the same types of cells,” Lein says.Now, researchers have a way to make sure the types of cells involved in a particular disease work the same way in people as in an animal model, Koch says.“The technology finally caught up with what we’ve been needing to do for probably over 40 years," says Tomasz Nowakowski, an assistant professor of anatomy at the University of California, San Francisco who co-wrote an editorial that accompanied the study.To compare mouse and human brain cells, researchers first analyzed sixteen thousand human brain cells taken from the middle temporal gyms, a part of the cortex(大脑皮层), the brain's outermost layer. Then they looked at cells taken from the same area of a mouse brain.“In one sense, they are remarkably similar,” Koch says, noting that both mice and human had about 100 different types of cells in this region of the brain. But a close comparison of 75 of these brain cell types revealed small differences.“Those cells are the immune(免疫的)cells of the brain,”Nowakowski says. “ And you might imagine that studies or insights into neuroimmune (神经免疫）disorders, for example, might be vastly affected by t his difference.“ And that could be one reason experimental Alzheimer’s drugs have helped mice, but not people.1.Why do the researchers compare mouse and human brain cells?A. To develop some kinds of drugs.B.To improve accuracy in treatment.C. To find a way to cure brain disorders.D.To look for the reason for some medicalfailures.2.What makes many drugs effective for mice but not for people?A. The effects of different parts of the genes.B.The response of the chemical materials.C. Small but important differences in brain cells.D.Different gene expressions of different cells.3.What do the researchers expect of the result they have found?A. It’ll solve the present problem soon.B.It’ll give them the proper assistance to further study.C. It'll be very helpful for all diseases.D. It’ll help speed up the study of the genes.4.Where is this text most likely from?A. A diary.B. A guidebook.C. A novel.D. A newspaper.4、It is a question that has long puzzled scientists—exactly why are tigers orange? One might think it makes them more obvious-particularly against a leafy green forest background. WilliamBlake summed it up in his famous poem known by generations of schoolchildren: “Tyger, tyger, burning bright /In the forest of the night.” But now the an swer is at hand.While obvious to us, computer simulations (模拟) of what the big cats look to the main animals they hunt for, deer, show a different picture. Humans with normal colour vision, can see red, blue and green colours. But deer can only pick up blue and green light, they are effectively colourblind to the colour red, like some humans. It means the tigers’ orange colouration looks green to them, allowing them to mix perfectly into the background, new research claims.Dr John Fennell at the University of Bristol and colleagues said that they used computers to estimate how noticeable a given animal was. They did this by using images of the environment in which the animal lives, and then creating images to see whether the camouflage helps the animal to mix in.Dr Fennell writes that by simulating what the world looks like to animals who are“two-colour vision”—someone who cannot discover the difference between red and green—“we also identify the most suitable colours for hiding and visibility”.Dr Fennel l writes in the Royal Society Journal Inter face: “Considering the coat of a tiger, it has fur that appears orange to a three-colour vision observer rather than some shade of green, though the latter should be more appropriate color for an attack hunter in forests. However, when viewed as a two-colour vision observer, the tiger’s colour is very effective.”The question then arises as to why tigers don’t grow green coats. Dr Fennell and colleagues write that mammals (哺乳动物) are not able to produce green fur. To do so would “require a significant change to mammalian biochemistry”. There is only one mammal known to have green fur but this is achieved through what might be considered as, well, cheating, not exactly real.1.Why does the author mention the poem in paragraph 1?A.To arouse reader s interest in poems.B.To show the authors respect to the poet.C.To answer the question of the color of the tigerD.To stress the noticeable color of the tiger to us.2.What color is inexistent in the eyes of deer?A.Zlack.B.Red.C.Blue.D.Green.3.What does the underlined word “camouflage” mean in paragraph 3?A.The cover of something.B.The images of something.C.The way of hiding something.D.The way of hunting for something.4.What can be inferred from the last paragraph?A.The colour of tigers sometimes cheats people.B.Getting green may prevent tigers from being extinct.C.There are no mammals with real green fur in the world.D.The tigers’ fur will probably evolve into green in the future.5、根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。
