Are you having difficulty falling asleep? Try drinking a glass of warm milk. If that doesn’t work, listen to some soft, beautiful music. Still no luck? Try think about sheep jumping over a fence. If you are still awake, take a sleeping pill. People who take pills often become dependent on the drugs. So you lie awake knowing that the new workday will soon arrive. If you have been in such condition for at least one month, you may have primary insomnia(失眠癥).

A new study has found that you might fall asleep more quickly and stay asleep longer if you try “cerebral hypothermia.” It is not a complex medical process. It just means cooling down your brain. Eric Nofzinger and Naniel Buysse from the University of Pittsburgh Medical School led the study. They examined twelve people who had sleeping problems. Twelve others had no sleeping problems. Each of them wore a soft plastic cap on their head at bedtime.

The caps had tubes inside filled with water. The researchers moved the water through the tubes and then changed the temperature of the water. Other studies showed that people who had sleeping problems often had more chemical reactions in the front of their brain. The researchers thought cooling down the brain might help.

On the first two nights of testing, the patients wore caps with no water. On the next two nights, the caps were worn, but the water was not cooled. Then the researchers cooled the water a little for another two nights. On the final two nights of the study, the temperature of the water was made much cooler. The researchers found that the water caps didn’ t help the patients until the temperature was about 14℃. Most of the patients fell asleep faster and slept better when the coolest water was moving around their head.

Dr Nfzinger and Dr. Buysse noted that this was only the beginning of the brain temperature study. But they believed they had discovered something important that needed more research.

George Max showed up in a well-maintained lorry. He brought some tools, such as something to light a fire with, a smoker, a long-handled brush, a metal hive(蜂箱)tool, and a hive. As George moved about, he said in a low and calm voice, “You’d be amazed how many people call me with a swarm(一大群)like this; and by the time I come, they’ve destroyed the whole thing, down to the last bee.”

George said this swarm of bees was breath-taking, about 15,000 bees. He placed the hive in a proper place. Holding the smoker close to the swarm, he pumped the bellows(風(fēng)箱). Smoke has a calming effect on bees. George said this group was easy to deal with. They were heavy with honey, and their main purpose was to hold the group together until they could find a new hive.

He went on smoking the swarm and let the bees pour into the hive. Most bees would only follow the queen to a new living place (yes, she has ladies-in-waiting that tend her every need). By dusk, most of the bees had disappeared into the hive.

“Alright, it appears that we’ve got them all,” I looked hopefully in George’s direction. He paused. “If you don’t mind, we’ll wait a bit longer,” he said. “They have sent out scout bees, and I want to be sure we don’t leave any behind.” So we waited. And, look! Scout bees returned.

If the hive is healthy, the population of bees will be on the increase. When the queen senses that it’s time for the hive to split, she will lose weight so she can fly, and then leave the hive with a large part of the bees. The bees left behind will hurry to hatch another queen and rebuild.

If some day you come across a swarm of bees in your backyard, call in a local beekeeper. Then sit back and enjoy the show. Get your camera, because you’ll want to share this amazing phenomenon with everyone you know, especially children. And if you’ve gone this far, you might as well buy a hive of your own. We did.

1.George thought the bees weren’t difficult to handle mainly because ______.

A. they were in huge quantity

B. his smoke had a healing effect on them

C. the bees were keeping together the group

D. they didn't need a new hive

2.George wanted to wait a little longer because ______．

A. there might be some bees that hadn’t come back

B. those bees which he had sent away didn’t return

C. the longer he stayed, the more honey he’d collect

D. the queen hadn’t turned up

3.We can infer from the last but one paragraph______．

A. the queen must keep fit to control others

B. the queen will leave if she finds no one supports her

C. fatty queens are not welcome in a hive

D. there is only one queen in a hive

4.How is the whole passage mainly developed?

A. By analyzing causes.

B. By giving examples.

C. By giving descriptions.

D. By making comparisons.

科目：高中英語(yǔ) 來(lái)源：河北省2017屆高三上學(xué)期第14周周測(cè)英語(yǔ)試卷 題型：短文改錯(cuò)

Recently the students in our class have had a heated discussion on if people should keep pets at home in cities. We have two different opinions.

Some students thought it’s a good idea to keep pets because many old people who will live alone at home can get some comfort from them. Besides, get along well with animals will make our life interesting. However, other students are against the idea. In their opinions, if too many people keep pets at home, it’s harmful for the environment. What is worse, pets may make too many noise and even attack people.

As for me, I’m in favor of the former. I don’t think it’s bad for us to keep pets at home. But you must take some measures to prevent them from serious polluting our environment.

The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid---we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.

However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus, a lizard (蜥蜴)native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water’s surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we，d need huge feet that we could bring up to our ears in order to create adequate w hitting. ’’

But fortunately there is an alternative : cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a “non-Newtonian” liquid that doesn’t behave like normal water. Now, if the surface of the water is hit hard enough, particles(粒子）in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick Liquid of cornflour.

Fun though all this may sound, it’s still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink--and take a shower afterward!

1.Walking on water hasn’t become a reality mainly because humans______.

A. are not interested in it

B. have biological limitations

C. have not invented proper tools

D. are afraid to make an attempt

2.What do we know about Basilicus basilicus from the passage?

A. It is light enough to walk on water.

B. Its huge feet enable it to stay above water.

C. It can run across water at a certain speed.

D. Its unique skin keeps it from getting wet in water.

3.What is the function of the cornflour according to the passage?

A. To create a thick liquid.

B. To turn the water into solid.

C. To help the liquid behave normally.

D. To enable the water to move rapidly.

4.What is the author’s attitude toward the idea of humans’ walking on water?

A. It is risky but beneficial.

B. It is interesting and worth trying.

C. It is crazy and cannot become a reality.

D. It is impractical though theoretically possible.

Is There Life on Earth

There was great excitement on the planet of Venus this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.

The satellite was directed into an area known as Manhattan(named after the great Venusian astronomer Prof. Manhattan, who first discovered it with his telescope 20,000 light years ago). Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to the feasibility(可行性)of a manned flying saucer(飛碟)landing on Earth. A press conference was held at the Venus Institute of Technology.

“We have come to the conclusion, based on last week’s satellite landing,” Pro. Zog said, “that there is no life on the Earth.”

“How do you know this?” the science reporter of the Venus Evening Star asked.

“For on thing, Earth’s surface in the area of Manhattan is composed of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide and other deadly gases and nobody could possibly breathe this air and survive.”

“What does this mean as far as our flying saucer program is concerned?”

“We shall have to take our own oxygen with us, which means heavier flying saucer than we originally planned.”

“Are there any other risks that you discovered in your studies?”

“Take a look at his photo. You see this dark black cloud floating over the surface of Earth?” We call this the Consolidated Edison Belt. We don’t know what it is made of, but it could give us a lot of trouble and we shall have to make further tests before we send a Venus Being there.”

“If what you say is true, won’t this set back the flying saucer program several years?”

“Yes, but we shall proceed as soon as the Grubstart gives us the added funds.”

“Pro. Zog, why are we spending billions and billions of zilches to land a flying saucer on Earth when there is no life there?

“Because if we Venusians can learn to breathe in an Earth atmosphere, then. We can live anywhere.”

1.The Venusians were excited this week because they __________.

A. landed a satellite with Venus astronauts on Earth

B. made a first-rate flying saucer

C. got an Earth Being to Venus

D. directed a satellite into Earth

2.According to Pro. Zong, why will the Venusians have to take their own oxygen with them?

A. Because they need it on their way to the planet of Earth

B. Because the Earth’s atmosphere is filled with deadly gases

C. Because deadly gases is far from enough on Earth

D. Because there is no air on the planet of Earth

3.The “dark black cloud” in the photograph refers to _________.

A. the polluted air floating over the surface of Earth

B. the mass of tiny drops of water floating above Earth

C. the concrete that is unknown to everywhere

D. the dark clouds gathering before a storm breaks

4.What’s the purpose of the writer?

A. to arouse the awareness of protecting the earth

B. to introduce a Venusians’ science program

C. to tell us the serious pollution of the Venus

D. to tell us an exciting Venusians’ exploration
