英语四级详细参考答案（全三套）四级听力1听力第一套Section ANews Report OneA message in a bottle sent out to sea by a New Hampshire man more than five decades ago was found 1500miles away and he’s been returned to his daughter. The long lost message was discovered by Clint Buffington of Utah while he was vacationing. Buffington says he found a soda bottle half-buried in the sand that looked like it had been there since the beginning of time.The note inside the bottle said, "Return to 419 Ocean Street and receive a reward of $150 from Richard and Tina Pierce, owners of the beach Comber motel.The motel was owned by the Paula Pierce in 1960. Her father had written the notes as a joke and had thrown it into the Atlantic Ocean. Buffington flew to New Hampshire to deliver that message to Pola Pierce.

The insects spraying over the weekend left more than 2 million bees dead on the spot in Dorchester county South Carolina, where four travel-related cases of Zika disease have been confirmed in the area. Most of the deaths came from Flower Town Bee farm, a company in Somerville that sells bees and honey products. Juanita Stanley who owns the company said the farm looks like it's been destroyed. The farm lost about 2.5 million bees. Dorchester county officials apologized for the accidental mass killing of bees.Dorchester County is aware that some beekeepers in the area that was sprayed on Sunday lost their bee colonies.County manager Jason Ward said in a statement. “I'm not pleased that so many bees were killed.”Questions 3 and 4 are based on the news report you have just heard.3.

The Airlander 10 spent nearly 2 hours in the air having taken off from Coddington airfield in Bedfordshire. During its flight it reached 3000 feet and performed a series of gentle turns all over a safe area. The aircraft is massive as long as a football field and as tall as 6 double decker buses and capable of flying for up to 5 days. It was first developed for the US government as a long range spy aircraft, but was abandoned following budget cutbacks. The aircraft cost25 million pounds and can carry heavier loads than huge jet planes while also producing less noise and omittingless pollution. The makers believe it's the future of aircraft and one day we'll be using them to go places. But there's still a long way to go. The Airlander will need to have 200 hours flying time before being allowed to fly by the aviation administration if it passes though we can hope we'll all get some extra legroom.Questions 5 and 7 are based on the news report you have just heard.5. What do we learn about the first flight of the Airlander 10?6. What caused the US government to abandon theAirlander 10 as a spy aircraft?7.

What do we learn about Katherine’ schoolmate Bree?Section CPassage OneHave you ever felt like you would do just about anything to satisfy your hunger? A new study in mice may help to explain why hunger can feel like such a powerful motivating force. In the study, researchers found that hunger outweighed other physical drives, including fear, thirst and social needs.To determine which feeling won out, the researchers did a series of experiments. In o ne experiment, the mice were both hungry and thirsty. When given the choice of either eating food or drinking water, the mice went for the food, the researchers found. However, when the mice were well-fed but thirsty, they opted to drink, according to the study. In the second experiment meant to pit the mice's hunger against their fear, hungry mice were placed in a cage that had certain "fox-scented" areas and other places that smelled safer (in other words, not like an animal that could eat them) but also had food. It turned out that, when the mice were hungry, they ventured into the unsafe areas for food. But when the mice were well-fed, they stayed in areas of the cage thatwere considered "safe." Hunger also outweighed the mice's social needs, the resear chers found. Mice are usually social animals and prefer to be in the company of other mice, according to the study. When the mice were hungry, they opted to leave the company of other mice to go get food.Questions 16 to 18 are based on the passage you have just heard.16. What is the researchers’ purpose in carrying out the serious experiment with mice?17. In what circumstances, do mice venture into unsafe areas?18. What is said about mice at the end of the passage?Passage TwoThe United States has one of the best highway systems in the world. Interstate highways connect just about every large and mid-sized city in the country. Did you ever wonder why such a complete system of excellent roads exists? For an answer，you would have to go back to the early 1920s. In those years, just after World War I, the military wanted to build an American highway system for national defense. Such a system could, if necessary, move troops quickly from one area to another. It could also get people out of cities in dan ger of being bombed. So-called roads of national importance were designated, but they were mostly small country roads. In 1944, Congress passed a bill to upgrade the system, but did not fund the plan right away. In the 1950s, the plan began to become a reality. Over $25 billion was appropriated by congress, and construction began on about 40,000 miles of new roads. The idea was to connect the new system to existing expressways and freeways. And though the system was built mostly to make car travel easier, defense was not forgotten. For instance, highway overpasses had to be high enough to allow trailers carrying military missiles to pass under them. By 1974, this system was mostly completed. A few additional roads would come later. Quick and easy travel between all parts of the country was now possible.Questions 19 and 21 are based on the passage you have just heard.19. What does the speaker say about the American highway system?20. What was the original purpose of building a highway system?21. When was the interstate highway system mostly completed?Passage ThreeTexting while driving was listed as a major cause of road deaths among young Americans back in 2013. A recent study said that 40% of American teens claim to have been in a car when the driver used a cell phone in a way that put people in danger. This sounds like a widespread disease but it's one that technology may now helped cure. T.J. Evarts, a 20- year-old inventor, has come up with a novel solution that could easily put texting drivers on notice. It's called Smart Wheel, and it's designed to fit over the steering wheel of most standard vehicles to track whether or not the driver has two hands on the wheel at all times. Evarts’ invention warns the drivers with the light and the sound when they hold the wheel with one hand only, but as soon as they place the other hand back on the wheel the light turns back to green and the sound stops. It also watches for what's called “close by hands”, where both hands are close together near the top o f the wheel so the driver can type with both thumbs and drive at the same time. All the data Smart Wheel collects is also sent to a connected app. So any parents who install Smart Wheel can keep track of the teens’ driving habits. If they try to remove or damage the cover, that's reported as well.Questions 22 to 25 are based on the passage you have just heard.22. What is a major cause of road deaths among young Americans?23. What is Smart Wheel?24. What happens if the driver has one hand on the wheel?25. How do parents keep track of their teens’ driving habits?参考答案：ABBCA CDADC BDCAD BACDB ABACB2听力第二套参考答案：Section A1.

This kind of loneliness is not serious. In fact, it’s quite normal. For some people, though, loneliness can last for years. Researchers say there’re three different kinds of loneliness.The first kind of loneliness is temporary (暂时的). This is the most common type. It usually disappear quickly and does not require any special attention. The second kind, situational loneliness, is a result of a particular situation – for example, a family problem, or the death of a loved one. Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually doe not last for more than a year.The third kind of loneliness is the most severe. Chronic (长期的) loneliness lasts more than two years and has no specific cause. People who experience habitual loneliness have problems socializing and becoming close to others. Unfortunately, many chronically lonely people think there’s little they can do to improve their condition.Psychologists are trying to find ways to help habitually lonely people for two reasons: they are unhappy and unable to socialize and there is a connection between chronic loneliness and serious illness such as heart disease. While temporary and situational loneliness can be a normal and healthy part of life, chronic loneliness can be a very sad dangerous condition.B 6. How would you treat temporary loneliness according to the passage? .A. Talk to friends.B. Just ignore it.C. Go to see a doctor.D.
