Earthquakes may rightly be ranked as one of the most destructive forces known to man: since records began to be written down, it has been estimated that earthquake-related fatalities () have numbered in the millions, and that earthquake-related destruction has been beyond calculation. The greater part of such damage and loss of life had been due to collapse of buildings and the effects of rockslides, floods, fire, disease, tsunamis, and other observable events resulting from earthquakes, rather than from quakes themselves.
The great majority of all earthquakes occur in two specific geographic areas. One such area covers the Pacific Ocean and its bordering landmasses. The other extends from the East Indians to the Atlas Mountains, including the Himalayas, Iran, Turkey and the Alpine regions. It is in these two great belts or zones that ninety percent of all earthquakes take place; they may, however, happen anywhere at any time.
This element of unknown has for centuries added greatly to the dead and horror surrounding earthquakes, but in recent times there have been indications that earthquake forecast may be possible. By analyzing changes in animal behavior, patterns of movements in the earth's shell, variations in the earth's force of attraction, and the frequency with which minor earth shakes are observed, scientists have shown increasing success in expecting when and where earthquakes will strike. As a result, a worldwide earthquake warning network is already in operation and has helped to prepare for (and thus lessen) the vast destruction that might otherwise have been totally unexpected.
It is doubtful that man will ever be able to control earthquakes and get rid of their destructiveness altogether, but as how and why earthquakes happen become better understood, man will become more and more able to deal with their possible damage before they occur.
60. Which of the following statements is true according to the passage?
A. Earthquakes destruction is declining.
B. Man is capable of conquering earthquakes.
C. Man is no longer fearful of earthquakes.
D. Earthquake forecast is improving.
61. We can infer from the passage that quakes _______ .
A. mostly strike in oceans and mountains
B. may happen anywhere at any time
C. are unperceivable in masses of land
D. are hardly the direct cause of fatalities
62. The underlined phrase "This element of unknown" in Paragraph 3 refers to__.
A. the extension of earthquake zones
B. the percentage of earthquake occurrences
C. when and where earthquakes may occur
D. what big damage earthquakes may cause
63. Man's research on earthquake forecast at present is to _________ .
A. lower the frequency of earthquakes
B. release the energy that causes earthquakes
C. reduce the loss from earthquake disasters
D. analyze the relationship between different earthquakes

You may know the Eiffel Tower as one of the most famous man-made monuments in the world, and you’d be absolutely right! Read on to learn about the history of the great Eiffel Tower.
Travelers from around the world flock(蜂拥)to Paris, France, to visit the Eiffel Tower, making it the most visited paid monument in the entire world! In fact, in 2010, the Eiffel Tower welcomed its 250 millionth visitor!
The history of the Eiffel Tower
The Eiffel Tower was named after the engineer Gustave Eiffel, whose company designed and built the famous monument. Construction began in January of 1887 and was completed in only two years. Their plan was to finish the tower in time to be the entrance arch for the World’s Fair in 1889. This fair celebrated the 100th anniversary of the French Revolution, which took place from 1789 to 1799.
The height competition
Located on the Champs de Mars, the tower is the tallest structure in Paris. It was the tallest man-made structure in the world for 41 years until the Chrysler Building in New York surpassed(超过) it. Then the spire(塔尖) on the top of the tower was added, raising its height to 17 feet taller than the Chrysler Building. It is now 1,063 feet tall! There are two replicas(复制品) of the Eiffel Tower in the world: a half scale model at the Paris Hotel in Las Vegas and a full-sized monument of a similar (but not exact) design in Tokyo, Japan.
Three shades of wonder
Some pictures make the Eiffel Tower look like a dark iron color. But it is, in fact, bronze. Not only that, but the tower is actually painted three different shades to make it appear even taller: darkest on the bottom and lightest on the top.
1.The Eiffel Tower was constructed to ________.
A. show great respect for Gustave Eiffel
B. make Paris the most visited city in the world
C. show the French people’s construction skill

Flying devices called drones(无人机) may be one of the most important technologies of the future.
The number of jobs for people who know how to design, build and control them is increasing. Because of this increase, several U.S. universities have started offering degrees in unmanned aircraft systems, or UAS.
One of these universities is the University of Washington in Seattle. Ward Handley is seeking a master’s degree in UAS at the university. When the drone program first began, he did not think it was a good idea. “Drones can be used to invade privacy(侵犯隐私).” He said. But later, Handley changed his opinion. He said, “I think there are good enough purposes for them.”
The FAA (the part of the U.S. government that controls air travel and traffic) is creating new rules to control the use of drones, however. A new law requires drone owners to register(登记) their drones. People who do not register their drones could face fines of up to US$20,000.
The new rules may also present problems for students. One problem is finding a legal place to fly.
Students at Blue Mountain Community College fly inside the college gym. In Seattle, University of Washington students test their drones in a big room.
Christopher Lum, a scientist at the University of Washington, helps students explore how drones can safely share the sky with regular aircraft. Lum explained why they test drones inside a building, “We need to register our aircraft and get permission to fly outside. That process can take months.”
At this time, Kansas State University is the only school with permission to offer unmanned aircraft flight classes to students outside. The FAA selected Kansas State University and 15 other universities to be part of a national research group.
Lum and some of his students recently moved their research to Australia. Australia has fewer rules limiting drones. A professor at Western Washington University also took his department’s drones to Canada for the same reason.
1.Degrees in UAS were created in several U.S. universities because of ________.
A. the increasing interest in the field
B. the increasing employment opportunities
C. the support from the government
D. the development of this technology
2.Why didn’t Handley think the drone program was a good idea at first?
A. Drones can be used for bad purposes.
B. The use of drones was very limited.
C. Few people can benefit from the program.
D. The university didn’t attach great importance to the program.
3.According to Lum, why does he teach flight classes inside a building?
A. It’s safer for the students.
B. It’s very expensive to register the aircraft.
C. It takes a very long time to get official permission.
D. He hasn’t got permission from the university.
4.What can we infer from the last two paragraphs?
A. Australia is promoting the use of drones.
B. Kansas State University is the first to offer a UAS degree.
C. Australia has fewer rules than Canada to control the use of drones.
D. The U.S. has more rules than Canada to control the use of drones.

It just may be the world’s most costly vacuum cleaner ( 吸尘器). The price of CleanSpace One is eleven million dollars. But yet, it has a big job to do. Recently, researchers in Switzerland said they planned to build this new cleaning machine.
CleanSpace One will not be for use in homes or businesses. It will be shot into space to help remove thousands of pieces of space junk floating around up there.
Last year, we reported on the problem of space junk. Over time, many unused spacecraft have hit each other far above the Earth. Big pieces break into thousands of small pieces. Sometimes they fall back into the atmosphere (大气层) and burn up. But when they do not, it creates big problems.
Scientists fear that if something is not done to remove these objects, it may soon become too dangerous to send people and machines into space. There is a large chance that they might hit some of this junk. So that is why the Swiss researchers are developing the new machine.
CleanSpace One is not really a vacuum cleaner. It will not be used to take away space junk. But scientists plan to move it close to an old satellite that is no longer being used. Then a claw-like instrument will catch the satellite, and force it back through the atmosphere. There, the satellite will be destroyed by the heat of friction (摩擦) with the air.
Researchers say that all they need to do is slow down the speed of some of these unwanted objects. Once they begin to move more slowly, they will fall back to the Earth. There is little chance that they will fall through the atmosphere and harm the people or things below.
1.Space junk is created when .
A. unused spacecraft hit each other
B. people in space throw away rubbish
C. a new spaceship is sent up
D. an old spaceship creates friction with the air
2.What’s the danger of space junk?
A. It will pollute space.
B. It will hurt people on the Earth.
C. It will hit a spaceship.
D. It will burn in the atmosphere.
3.Unwanted objects will fall back to the Earth when .
A. they are made to move slowly
B. they meet other objects in space
C. they are not used for years
D. they are near the atmosphere
4.The passage is most probably a .
A. science research paper B. science fiction story
C. newspaper ad D. science news report

AIDS may be one of the most undesirable diseases in the world. Luckily, there is now hope for AIDS patients.
According to a recent paper published in the New England Journal of Medicine, Chinese scientists have successfully used CRISPR technology - a method of gene editing - to treat a patient with HIV. While it may not have cured the patient fully, it still represents a huge step forward in fighting the disease.
The patient was a 27-year-old Chinese man who was diagnosed with both AIDS and acute lymphoblastic leukemia (急性淋巴细胞白血病), a type of blood cancer. Despite his hopeless situation, doctors offered him a glimmer of hope: a bone marrow (骨髓) transplant to treat his cancer and an experimental treatment for his HIV.
They used this opportunity to edit the DNA in bone marrow stem cells from a donor before transplanting the cells into the patient.
Specifically, the treatment involved using the gene-editing tool CRISPR-Cas9 to delete a gene known as CCR5, which encodes a protein that HIV uses to get inside human cells. Without the gene, HIV is unable to infiltrate cells.
Talking about the gene, lead scientist Deng Hongkui told CNN, “After being edited, the cells - and the blood cells they produce - have the ability to resist HIV infection.”
Nineteen months after the treatment, the patient’s leukemia was in complete remission (缓解) and donor cells without CCR5 remained, according to the research paper.
Though the transplant did not cure the man’s HIV, it still showed the effectiveness of gene-editing technology, as there was no indication of any unintended genetic alterations - a major concern with past gene therapy experiments.
Amesh Adalja, a senior scholar at the Johns Hopkins Centre for Health Security in the United States, who was not involved in the study, praised the treatment.
“They did a very innovative experiment. It was safe,” he told Live Science. “It should be viewed as a success.”
Deng believes gene-editing technology could “bring a new dawn” to blood-related diseases such as AIDS and sickle cell anemia (镰刀形细胞性贫血).
“Thanks to this new technology, the goal of a functional cure for AIDS is getting closer and closer,” he said.
1.The technology of CRISPR is to ___________.
A.transplant cells B.encode genes
C.remove proteins D.produce cells
2.What was the result of the treatment?
A.CCR5 and other genes in the patient’s cells were changed.
B.The number of cells infected by HIV decreased.
C.Some of the patient’s blood cells could resist HIV infection.
D.HIV no longer existed in the patient’s cells.
3.What do we know about the experiment?
A.It provided an innovative way to cure AIDS patients.
B.It pointed out the problems of gene therapy.
C.It could offer a safe treatment for blood-related diseases.
D.It’s the first experiment to use gene-editing technology to treat AIDS.

“Check it again, you need to be sure.”This culture rule may sound , but it is one of the most powerful culture rules. I took a lot of things for granted. In fact, I used to people who often check things, such as their car engine oil, the house security, even the children in the bedroom. I didn’t realize that this rule would cost me dearly.
One day the owner of the supermarket I worked in asked me to make a(n) to the investors(投资者) whom we wanted to become partners with. I was given a month to it.
The day of the presentation arrived. I left home at 7 am with the intention of getting to the office . On the way , my car climbed over a bunch of rocks and I heard a loud noise. I stepped on the brake and got out of the car to check what happened: I had a flat tire.

DNA is one of the most important discoveries in science. DNA is the plan for the human being, as a blueprint is the plan for a building. DNA makes a person look the way he does. A person’s DNA comes from a mixing of his parents’ DNA. That’s why a child looks like his parents. But, besides controlling things such as height and hair color, DNA can also give people diseases. Scientists are now studying DNA to cure diseases.
In the seventies, scientists developed a process called recombinant or RDNA. Although it sounds difficult to understand, RDNA simply means taking DNA from one animal or plant and putting it into another. By doing so, scientists can create new beings. In doing so, scientists can better understand DNA, especially what parts of DNA do what. After they understand DNA, scientists can begin to cure diseases. Often, the new being created will itself be the cure. Besides curing diseases, RDNA research can also do other things. For example, scientists in Japan have already created “super-trees”. Trees help humans, because they take CO2, which poisons humans, from the air and turns it into oxygen, which lets humans breathe. “Super-trees” do this too, but do it much faster. As things such as cars and factories have already put much CO2 in the area, “super-trees” are badly needed.
Unfortunately, there is a serious danger in RDNA research. Scientists want to create animals to cure old diseases, but these new animals may also create new diseases. It will be a serious problem if the animals escape from the science laboratory and into nature. As these animals are not natural, they may let loose many new powerful diseases.
As a result, RDNA research will create many solutions, but it will also create many problems.
1. From the passage, we can know that a boy looks like his parents because______.
A. he is son of his parents.
B. his parents’ DNA decides his appearance.
C. he has received DNA from his father or his mother.
D. scientists have put some of his parents’ DNA into him.
2.What does the underlined expression “let loose” probably mean?

Countries may be ranked by many various groups, such as how expensive or interesting they are to foreign tourists. They can also be ranked by their openness and friendliness toward visitors. You might be shocked to find out that, for example, the USA is number 102 on the list of the least welcoming places, 140 being the most unfriendly land.
Mongolia
Mongolia was closed for quite some time and opened up to foreigners only 20 years ago. That’s probably the major reason why it is not yet experienced enough in hosting tourists. The country is beautiful, with huge spacious areas of land that are low populated. There local people are not yet used to being visited by foreign guests.
Slovakia
There are, undoubtedly, pluses as well as minuses in every country. Slovakia is not the perfect destination for a couple of reasons. First and foremost, Slovakia is becoming more and more similar to the rest of European countries surrounding it. Sameness is not the best quality. As a rule, tourists want to travel and see things they have never seen before. It is good that the land’s countryside is still unique, although it is also being commercialized day by day.
Iran
Iran is not the best place to travel to. It is located close to Pakistan with its negative political atmosphere. Western visitors are not welcome over there and embassies (大使馆) advise against traveling to Iran. The population, contrary to the country’s government, consists of very friendly and welcoming people.
Kuwait
In Kuwait people are warm and friendly. It has a unique history, plenty of traditions and customs. People respect their culture and are very religious. It is a Muslim country, which means that you are not allowed to drink alcohol. If you happen to visit Kuwait during Ramadan, you will not be allowed to eat in public places, either.
Russia
Russia is truly a special place. It is definitely worth visiting. What you might not find attractive is the corruption and bureaucracy (官僚主义) that rule in some certain official circles. Another nuisance you should be ready for is that, as a visitor, you’ll be asked to receive an invitation. Only then will you be able to apply for a visa. Once you arrive in Russia, you’ll be warmly greeted and accepted by the local people.
1.You’ll meet friendly people in the following countries except in _____.
A. Iran
B. Kuwait
C. Mongolia
D. Russia
2.Which of the statements is true according to the text?
A. You can apply for a visa for Russia at will.
B. If you’re fond of drinking, then Kuwait is not an ideal destination.
C. You’re not advised to travel in Iran due to its high cost.
D. Mongolia is a beautiful country with much experience in hosting tourists.
3.Where does this passage probably come from?
A. A news report
B. A lecture speech
C. An advertisement
D. A text book

While you may be doing everything right, ignoring just one or two steps in the process may keep you from getting a job, especially in this fierce market. Here is a checklist that covers some of the major links in the job-search chain.
THE RESUME --- Make sure it is up-to-date and tailored to the types of jobs you are seeking for. Have someone else look at your resume. If you cannot afford a career coach, give your resume to friends or family members to scrutinize. Have copies of your resume printed so that you are ready to hand them out at interviews.
COVERING LETTERS---Maybe you’ ve set up a few basic styles in advance, but that’s not enough. Each covering letter should be designed to suit the job for which you are applying.
THE WARDROBE(衣橱)---Check your wardrobe to ensure that you have the appropriate professional dress, including shoes, ready for interview.
NETWORKING---Don’t isolate yourself from others for days. Network through e-mail messages, phone calls, appointments and meetings keep you in touch with the outside world and prevent you from becoming depressed.
APPLICATION---A glance at huge online job sites isn’t usually the best way to find a job. You are more likely to succeed through the people you know via networking.
THE FOLLOW—UP---It is quite common to apply for job and never hear back from the company. Take measures, such as following up with a phone call a week or so after you apply. If you know someone at the company, check whether that person will put in a good word for you.
INTERVIEWS----If you’ ve got plenty of interviews but no return calls or job offers, take a look at your interviewing skills. This is one area where investing in a career coach may pay off. But if you can’t afford one, try to find a job group or service that conducts free mock(模拟) interviews.
SUPPORT SYSTEMS---Finally, recognize that looking for job is rather difficult. Even at the best of times, a job hunt is often about rejection, and that can be hard to endure. Staying in touch with family, friends, professional networks and fellow job seekers can help you to maintain a positive attitude and a sense of perspective.
It is implied in the text that__________.
A.people often pay no attention to writing their resume
B.the interview is the most difficult step for interviewees
C.a career coach often offers free mock interviews to interviewees
D.your social network may help you a lot in your job hunt
