Officials in the Midwestern U. S. town of Joplin, Missouri, say the death from Sundays’ big tornado reaches 116 and that search efforts continue for possible survivors trapped in rubble (碎石). Search and rescue teams are conducting their third sweep through the nearly 10 kilometer – long and one – kilometer wide area of destruction left by the tornado. They are working as quickly as possible while weather conditions remain relatively stable. More storms are forecast for the area.

Joplin Fire Chief Mitch Randles said there are areas with large piles of rubble that might hold survivors. “We are still finding individuals. We did rescue seven individuals from underneath rubble yesterday and, of course, we are also finding dead folks as well.” Said more folks and that is why we are doing these searches. We want to make every opportunity that we can to find everybody that is in the rubble and that has survived to this point.”

Randles said the current sweep involves a slower pace that previous searches and that he plans a fourth search, possibly on Wednesday, using specially trained dogs. “We are searching every structure that has been damaged or destroyed in a more in-depth manner, “he said.” I have dogs and dog handlers coming from all over the country do help us in that effort.”

Joplin City Manager Mark Rohr said the Red Cross and other volunteer organizations are helping people who were left homeless by the tornado and that the Federal Emergency Management Agency, or FEMA, is on hand to help. “Joplin is a great city. We have suffered a great loss, “said Rohr.” We will recover and we will recover strongly and we have a lot of help and a lot of volunteers to make that easier.”

The tornado that struck Joplin was classified by the Natioonal Weather Service as an F – 4, with winds of more than 300 kilometers per hour. It lasted only 20 minutes, but it killed more that 100 people, injured more than 400 others, and destroyed or heavily damaged some 2,000 homes, businesses, churches and a hospital. Authorities have registered more than 1,700 calls about missing people and they hope to resolvemost of those cases soon, as victims are identified and survivors come forth and reunite with loved ones.

This was the worst tornado to strike the United States in 60 years. It was the latest in a wave of violent storms that have swept Midwestern and southern states in recent weeks, leaving more than 300 people dead an causing more than $2 billion dollars in damage.

In a study published in the U. S. journal Science, researchers from the Chinese Academy of Agricultural Sciences(CAAS) and the University of Florida identified the chemical combinations and genetic recipe for better tomato flavor(味道).

“In recent years, consumers often complain that the modern tomato is less flavorful than it once was” said co-principal researcher Sanwen Huang. “Our results provide a practical road map for breeding tomato varieties with better flavor.”

For the study, a 170-person consumer group was created to evaluate 160 tomatoes representing 101 varieties, based on qualities such as “overall liking” and “flavor degree”. The results pointed to dozens of chemical compounds of interest, and further research using a statistical model discovered 33 flavor compounds connected with consumer liking, such as glucose(葡萄糖). The reason why modern tomatoes don’t taste good anymore is that a total of 13 of these flavor-associated compounds “were significantly reduced in modern varieties,” their paper wrote. Moreover, the researchers found that smaller fruit tended to have greater sugar content, suggesting that “selection for more sizable tomatoes has cost sweetness and flavor”.

Based on this knowledge, Huang and Professor Harry Klee of the University of Florida studied the whole genomes of 398 varieties of tomato, identifying about 250 positions of genes on a chromosome(染色体), which controlled tomato flavor.

“We’re just fixing what has been damaged over the last half century to push them back to where they were a century ago,” said Klee in a statement. “We can make the supermarket tomato taste noticeably better.” Klee said new tomato varieties with better flavor could be ready in three to four years. In addition, “the genes and pathways identified here in the tomato almost certainly point to pathways worth researching for improvement of flavor quality in other fruit crops,” they wrote.

1.According to the text, the study ________.

A. was carried out just through a survey

B. was conducted by Chinese researchers themselves

C. was completely focused on the genes of different tomatoes

D. was done with the background of declining flavor of tomatoes

2.The researchers have found that ________ in the study.

A. bigger tomatoes are much sweeter

B. some genetic positions affect the taste of tomatoes

C. some chemical compounds make tomatoes less tasty

D. a total of 13 flavor-associated compounds make tomatoes appealing in taste

3.What is the influence of the study according to the text?

A. The study lays the foundation for further researches to improve other fruit crops’ flavor.

B. The study makes it possible for us to have noticeably more tasty tomatoes next year.

C. The study provides a road for where to plant tomatoes with better flavor.

D. The study has fixed all the genes of existing tomatoes.

Last year, the Bureau of Labor Statistics reported that 55 million people in the U. S. are “gig workers" which is more than 35 percent of the U. S. workforce. That number is projected to jump to 43 percent by 2020.

People are drawn to gig work（零工）because it brings in a little extra income without a major time commitment. And recent technologies like Skype, Slack, and Dropbox have made the gig life a reality, giving you maximum freedom, an ideal work-life balance, and the chance to pursue your passions.

If you're thinking of joining the gig economy, it's never been easier. One of the great things about the gig economy is that you don't have a boss breathing down your neck. As a freelancer, you no longer have to cater to a company culture or work schedule that might cause physical or emotional stress. Instead, you get to choose the type of work you do and who you work with. But this degree of freedom requires a corresponding amount of discipline. With no boss to make sure you're on task, it's all on you.

A lot of gig workers start their careers by hopping on a project because the employer is desperate and in need of help. On the employer's end, it's tough to take on people for higher management positions when the pool of talent is full of gig workers who haven't been given an opportunity to improve their skills. Businesses have to evolve to learn how to account for an influx（(涌入）of temporary workers. It is harder for gig workers to become skilled and get promoted.

The workforce is becoming more advanced and educated by the day. You have to keep learning and keep up with industry trends to maintain a competitive edge. This is true even for people in traditional office settings, but it's critical if you're your own boss.

1.What made the gig life a reality?

A.Greater work-life balance. B.New technologies.

C.A little extra money. D.Maximum freedom.

2.What does the underlined phrase “breathing down your neck” in Paragraph 3 mean?

A.Making you unable to breathe freely.

B.Standing very close behind you.

C.Threatening you by saying something.

D.Monitoring you closely.

3.What can we infer from the last but one paragraph?

A.Employers should invest in training the temporary workers.

B.Gig workers start their jobs out of passion.

C.It's hard for employers to employ people for higher positions.

D.It's hard for gig workers to develop skills.

4.Which of the following can be the best title for the text?

A.The Strengths and Weaknesses of the Gig Economy

B.The Challenges of the Gig Economy

C.The Increase of the Gig Economy

D.The Reason for the Gig Economy

An estimated 60 percent of cats and 50 percent of dogs in the U. S. are overweight or obese, so chances are that your pet needs to lose weight rather than pack on some pounds. It's not always easy to tell if your pet could afford to lose few, but there are some other signs that can tip you off. One important factor the waist, "Most people don't know what a normal cat should look like," says Romine. "But cats should have waists, too." The vet says you should be able to feel your pet's ribs（肋骨） through its coat, and when you look down at them, they should have an hourglass（沙漏）shape---just like person.

"For some overweight pets, you may want to switch to new food entirely; foods with 'light' or 'healthy weight' labels usually have an increased fiber content to help the dog or cat feel fuller," Romine notes. "Another option is to feed them less of the food they currently cat," Freeman suggests. "Make sure you're reducing table scraps（残羹剩饭）and high-calorie treats like pet biscuits," she says.

It's important to figure out what your pet's ideal weight is as you're helping them to lose. Romine advises working with your vet to get the right number, and if you're following the portion guidelines often printed on food labels, feed them the amount of food associated with the weight you want them to be, rather than the weight they currently are.

Food isn't the only factor that can impact your pet's weight. Romine stresses the importance of exercise in keeping your pet healthy. For cats, just 10 minutes of indoor play each day can make a difference. For dogs, letting them out in the backyard to do their business is not enough. You'll have to exercise with your dog to really get them moving.

1.What is the problem with the pet from the text?

A.It needs to lose weight. B.It needs have waists

C.It needs to pack on pounds. D.It needs to be more energetic.

2.Which food can help overweight pets?

A.The food with an decreased fiber. B.The food from table scraps.

C.The food with "light" labels. D.The food with new label.

3.What is an important factor to keep pets healthy?

A.A partner. B.Exercise.

C.Pet biscuits. D.Protein.

4.From which is the text probably taken?

A.A biology textbook. B.A travel brochure.

In the U. S. state of Washington, a road called Interstate(州际公路；州际的)90 cuts through a wild mountainous area to reach the city of Seattle. For the area's many kinds of animals, busy high- way greatly limits their movements. Animals need to move to find food, to find mates, to find new places to live as their populations expand or just when conditions change, like a fire breaks out. Crossing I-90 – as the road is called – is a risky but sometimes necessary act. But soon, animals will have a safer choice. They will be able to go above it.

To help the animals, the state is finishing work on its largest - ever wildlife bridge. The 11-meter-tall, 20 - meter - wide bridge begins in the forest. It forms two arches above the highway, one for each direction of traffic. Workers are adding fencing anti plants to help guide the animals across the bridge，Two-meter-thick walls will help block noise from vehicles below. Scientists chose the area because it is within a natural migration(迁徙)path for some animals.

The I -90 bridge is part of a growing number of wildlife crossings across the United States. Some are fences, some are overland bridges，and some are underpasses. They all aim to keep drivers and animals away from each other.

A U. S. Transportation Department study found crashes between animals and humans rose year by year. The accidents made up about 5 percent of all crashes nationally, and cost the economy (经济)about ＄ 8 billion. Such costs come from car repaid, emergency room visits and removal of the dead animals on roads. Collisions between animals and drivers are rarely deadly to people. But they are often deadly to wildlife. The study also found that 21 endangered or threatened species in the U.S. are affected by vehicle hits. Bridges, underpasses and fencing reduce I he area's animal - driver collisions by 80 percent.

Most of the wildlife bridges are in western states. Many other areas also need such paths. But finding money for more crossings is“the- number - one problem”. Patty Garvey — Darda of the U. S. Forest Service has worked on the I - 90 crossing from the start of the project. She says the $ 6 - million bridge will one day pay for itself because the highway will not have to be fully or partly closed each time a large animal is struck. “If you shut clown Interstate 90, you shut down interstate trade. ” she adds.

1.What do we know about die I -90?

A. It goes from Washington D.C to Seattle,

B. It is dangerous for wild animals to cross.

C. It blocks the movements of wild animals.

D. It is the longest - ever highway in the world.

2.What is being done to help the animals?

A. Building a wildlife bridge to keep drivers and animals away.

B. Designing walls to protect animals from traffic accidents.

C. forming 2 arches, one for traffic and the other for animals.

D. Choosing a natural and safe area for wild animals to live in.

3.What can we learn from the study?

A. Traffic accidents went down gradually nationwide.

B. Most money was spent in rescuing wild animals,

C. Collisions are more deadly to wildlife than to people,

D. Some species no longer existed because of vehicle hits.

4.Which of the statements may Patty Garvey - Darda agree with?

A. The bridge costs too much money.

B. Animals won11 be struck by drivers.

C. The effort to build the bridge will pay off.

D. Collisions won't affect national trade at all.

The U. S. Postal Service (USPS) is losing billions of dollars a year. The government company that delivers "small mail" is losing out to email and other types of electronic communication. First-class mail amount fell from a high point of 104 million pieces in 2000 to just 64 million pieces by 2014.

Congress permits the 600.000-empIoyee USPS to hold a monopoly (垄断) over first-class and standard mail. The company pays no federal, state or local taxes; pays no vehicle fees; and is free from many regulations on other businesses. Despite these advantages, the USPS has lost $52 billion since 2007, and will continue losing money without major reforms.

The problem is that Congress is preventing the USPS from reducing costs as its sales decline, and is blocking efforts to end Saturday service and close unneeded post office locations. USPS also has a costly union-dominated workforce that slows the introduction of new ideas or methods down. USPS workers earn significantly higher payment than comparable private-sector workers. The answer is to privatize the USPS and open postal markets to competition. With the rise of the Internet, the argument that mail is a natural monopoly that needs government protection is weaker than ever.

Other countries facing declining letter amounts have made reforms Germany and the Netherlands privatized their national postal companies over a decade ago, and other European countries have followed suit. Britain floated shares of the Royal Mail on its stock exchange in 2013. Some countries, such us Sweden and New Zealand, have not privatized their national postal companies, but they have opened them up to competition.

These reforms have driven efficiency improvements in all of these countries. Additional number of workers have been reduced, productivity has risen and consumers have benefited. Also, note that cost-cutting measures—such as closing tone post offices—are good for both the economy and the environment.

Privatization and competition also encourage new changes. When the USPS monopoly over "extremely urgent" mail was stopped in 1979, we saw an explosion in efficient overnight private delivery by firms such as FedEx.

The government needs to wake up to changing technology, study postal reforms abroad and let businessmen reinvent our out-of-date postal system.

1.What do we know about the USPS?

A. Its great competitor is the delivery firm FedEx.

B. It is an old public service open to competitions.

C. Its employees don't pay federal, state or local taxes.

D. It has complete control of first-class and standard mail.

2.The author mentions some other countries in Paragraph 4 to __________.

A. explain the procedures of reform to the USPS

B. show the advantages of private postal services

C. set some examples for the government to learn from

D. prove the situation is very common around the world

3.The author probably that the USPS __________.

A. needs government’s protection as ever

B. can work together with other businesses

C. must be replaced by international companies

D. should be sold out and become a private service

4.Which of the following shows the development of ideas in this passage?

In only two decades Asian Americans have become the fastest growing U. S. minority. As their children began moving up through the nation schools, it became clear that a new class of academic achievers was emerging. Their achievements are reflected in the nation’s best universities, where mathematics, science and engineering departments have taken on a decidedly Asian character. This special liking for mathematics and science is partly explained by the fact that Asian-American students who began their education abroad arrived in the U. S. with a solid grounding in mathematics but little or no knowledge of English. They are also influenced by the promise of a good job after college. Asians feel there will be less unfair treatment in areas like mathematics and science because they will be judged more objectively. And the return on the investment in education is more immediate in something like engineering than with an arts degree.

Most Asian-American students owe their success to the influence of parents who are determined that their children take full advantage of what the American educational system has to offer. An effective measure of parental attention is homework. Asian parents spend more time with their children than American parents do, and it helps. Many researchers also believe there is something in Asian culture that breeds success, such as ideals that stress family values and emphasize education.

Both explanations for academic success worry Asian Americans because of fears that they feed a typical racial image. Many can remember when Chinese, Japanese and Filipino immigrants were the victims of social isolation. Indeed, it was not until 1952 that laws were laid down giving all Asian immigrants the right to citizenship.

1.While making tremendous achievements at college, Asian-American students ________.

A. feel they are mistreated because of limited knowledge of English

B. are afraid that their academic successes bear a strong Asian character

C. still worry about unfair treatment in society

D. generally feel it a shame to have to depend on their parents

2.What are the major factors that determine the success of Asian Americans?

A. A solid foundation in basic mathematics and Asian culture.

B. Hard work and intelligence.

C. Parents’ help and a limited knowledge of English.

D. Asian culture and the American educational system.

3.Few Asian American students major in human sciences mainly because ________.

A. their English is not good enough

B. they are afraid they might meet with unfair judgment in these areas

C. there is a wide difference between Asian and Western cultures

D. they know little about American culture and society

4.Why do “both explanations” (Para. 3) worry Asian Americans?

A. They are afraid they will again be isolated from American society in general.

B. People will think that Asian students only rely on their parents for success.

C. Asian Americans will be a threat to other minorities.

D. American academic achievements have taken on too strong an Asian character.
