We’d been flying for hours, deeper and deeper into the desert of southeastern Niger. The mission: to find what is probably the last wild population of the great Saharan antelope called the addax (旋角羚)—the most endangered animal of its size in Africa.
Pilot Peter Ragg flew our bright red helicopter low over two parallel dunes (沙丘). The pale sand below us was dotted by the black bushes, the plants that are favorite food for the addax. Then, almost as if the dune extruded (使突出) them, two perfect addaxes appeared. Their long tails swung from side to side as they ran, heads held high on thick necks, horns reaching for the sky. We made a few turns in the plane, then let them be. In just a few seconds they were swallowed again by the Sahara. Soon they could just as easily disappear from the planet.
In September 2004 the government of Niger and a small NGO called SOS Faune du Niger surveyed this last known pocket of wild addaxes. They counted 128 individuals. Since then, the number has dropped as hunters have taken more for meat. How many addaxes remain in the Sahara is anybody’s guess, but those that do survive could be considered the living dead: There may not be a viable (能生存的) population left to reproduce.
I’m now helping to make an emergency plan for the last wild addaxes. With a few hundred thousand dollars, some trucks, and a strong group with the local Toubou guides, we may just be able to save these guys from extinction.
36. What do the addaxes in the passage usually eat?
A. Vegetables. B. Black bushes. C. Grass. D. Fruits.
37. All of the following descriptions of the addax are true EXCEPT that ____.
A. its tail is long B. its neck is thick
C. its legs are short D. its horns are long
38. What does the writer probably mean by saying that “There may not be a viable population left to reproduce”?
A. Wild addaxes will die out soon unless effective measures are taken.
B. The number of wild addaxes will increase if they are not hunted.
C. Wild addaxes cannot support themselves any longer.
D. Humans cannot survive without enough addaxes.
39. It can be inferred that the writer of the passage might be ____.
A. a journalist B. an official C. an engineer D. a zoologist

People have been making and flying kites for about 2,000 years. 1.Some historians believe it the ancient Chinese may have started kite flying 2000 years ago. It is still a popular hobby in China, Japan and Korea and in other countries of the Far East where beautifully decorated appear in different colors.
2.Simple kites are made by crossing two sticks and covering them with paper or cloth. Then you attach a string at the end. More expensive kites have frames made of fiberglass, plastic or aluminum. The name comes from a graceful bird called kite.
3.A flat kite is the oldest and simplest type of kite. It flies because air flows over and under the kite's wing. The pressure under the wing helps the kite lift into the air.
4.Early scientists sent kites up into the air to measure temperature at different heights. In 1752, Benjamin Franklin used a kite to prove that lightning was a form of electricity. He attached a metal key to the string of a kite. When lightning hit the kite, electricity passed down the string and Franklin got an electric shock. It was a very dangerous experiment that you shouldn't copy.
Kites were also used to develop airplanes. The Wright Brothers experimented with kites before they flew the first airplane. 5. In World War I the Germans developed a large kite that could transport people to a submarine. Kites were also used to carry radio signals over long distances.

We humans love to stare into our smart devices. We gaze for hours—about 10 hours and 39 minutes a day—at our computers, smartphones, tablets and televisions. Is all this staring bad for us? It might be, mainly because as we stare at our devices we are exposing ourselves to blue light.
Blue light is a type of electromagnetic radiation with a very short wavelength that produces a high amount of energy. While it’s true that light can damage our eyes under certain circumstances, there’s no scientific evidence suggesting that blue light is harmful to our eyes. But many people still think it is, which is why blue—light—blocking glasses are so popular. So, do the glasses work?
“Everyone is very concerned that blue light may be causing damage to the eye, but there’s no evidence that it may be causing serious damage,” Dr.Rahul Khurana, a clinical spokesman, told Business Insider.
Blue light exposure is nothing new. In fact, the sun is the largest source of blue light. Moreover, blue light is also present in LED light. But if blue light isn’t harmful, then why are we constantly rubbing our eyes when we’re looking at our screens? The answer is eyestrain(眼疲劳). More than 60 percent of people experience eye problems associated with digital eyestrain. And blue light, it seems isn’t the cause. Instead, our eyes are so strained because most of us blink less when we stare at our digital devices. So, if eyestrain is the real issue, blue-light-blocking glasses are probably of little use.
1.What do we know about blue light?
A.It has the shortest wavelength.
B.It’s a kind of nuclear radiation.
C.It consumes a great deal of energy.
D.It may come from electronic devices.
2.What causes the popularity of blue-light-blocking glasses?
A.Evidence of their benefits to eyes.
B.Widespread use of smart devices.
C.Belief in blue light’s harmful effect.
D.Scientific understanding of blue light.
3.What can be inferred from Paragraph 4?
A.Rubbing eyes makes people strained.
B.Blue light exposure is hardly avoidable.
C.Blue light may connect with tired eyes.
D.Eye problems are not easy to deal with.
4.According to the text, wearing blue-light-blocking glasses may be _______.
A.useless B.harmful C.tiring D.beneficial

When I stepped out the plane from Miami into Charlotte, North Carolina, airport for a connecting flight home, I immediately knew something was wrong. Lots of desperate people crowded the terminal. I quickly learned that flights headed to the Northeast were called off because of a storm. The earliest they could get us out of Charlotte was Tuesday. It was Friday. A gate agent stood on the counter and shouted, “Don’t ask us for help! We cannot help you!”
I joined a crowd that ran from terminal to terminal in search of a flight out. Eventually, I found six strangers willing to rent a van with me. We drove through the night to Washington, where I took a train the rest of the way to Providence.
The real problem, of course, is that incidents like this happen every day, to everyone who flies, more and more often. It really gets to me, though, because for eight years I was on the other side, as a flight attendant for Trans-World Airlines(TWA).
I know the days are gone when attendants could be written up if we did not put the lines napkins with the TWA logo in the lower right-hand corner of the first-class diners’ trays. As are the days when there were three dinner options on flights from Boston to Los Angeles in economy class. When, once, stuck on a tarmac (机场停机坪) in Newark for four hours, a planeload of passengers got McDonald’s hamburgers and fries by thoughtfulness of the airline.
I have experienced the decline of service along with the rest of the flying public. But I believe everything will change little by little, because I remember the days when to fly was to soar (翱翔). The airlines, and their employees, took pride in how their passengers were treated. And I think the days are sure to come back one day in the near future.
1.Many people crowded the terminal because ________.
A. they were ready to board on the planes
B. something was wrong with the terminal
C. the flights to the Northeast were canceled
D. the gate agent wouldn’t help the passengers
2.The writer got to Providence ________ at last.
A. by air B. by van C. by train D. by underground
3.Which of the following is not true according to the passage?
A. Incidents happened to those who fly quite often.
B. The writer used to be a flight attendant for Trans-World Airlines.
C. Even a small mistake might cause complaints from passengers in the past.
D. McDonald’s hamburgers and fries were among regular dinner options.
4.What can be implied from the passage?
A. The writer lived in Charlotte, North Carolina.
B. The writer thought the service was not as good as it used to be.
C. The writer with other passengers waited to be picked up patiently.
D. Passengers would feel proud of how they were treated on the plane.
