BEIJING—The sky is gray and air smells strange. It’s another day of smog.
On Saturday, heavy haze（霾）still covered north and east China. Highways were closed and         couldn’t take off on time.
The smoggy weather         the country’s land from north to south, including Beijing, Hebei, Shandong, and 6 other provinces. People could only see clearly           than 50 meters in some areas.
Cities           Shanghai and Nanjing have been covered by the gray sky for the past several days. Many walkers in the street had to wear          . In the Lukou airport in Nanjing, more than 60 flights were canceled(取消) on Saturday            the haze, which also made primary and middle schools and kindergartens stop           on Thursday and Friday in Nanjing.
The office worker of Environmental Protection said earlier this week that there were several        reasons behind the widespread haze: unpleasant weather conditions making          difficult for smog to disappear, motor vehicle exhaust（尾气）, and coal use for winter heating.
To fight pollution, the Chinese government now plans to clean up the air by cutting coal use,         some factories, and removing 6 million old cars from the roads.
“We must face up to the facts,” said Yan Naiqiang, a professor of environmental science at Shanghai Jiao Tong University. “The treatment of smog will be a long fight. From now on, if we use buses or cars less and do more riding, we believe a clear sky is not a faraway dream.”

Mark began to introduce the guest speaker to the listeners, but then stopped for a while. He had forgotten her name.
Barbara hid her valuable things when she went on vacation. When she came back, she couldn’t remember where she’d put them.
Perhaps you’ve had such experiences like these. Most people have. But most of them haven’t realized that they have a memory problem. Neither do they know a simple but important fact: Memory can be improved. If you just accept that, the following will show you how.
First, relax. If you are over worried about something, you’ll forget it. If you keep telling yourself that your memory is bad, your mind will come to believe it and you won’t remember things. When you forget something, don’t follow up with saying like “Oh, my god! I always forget things! ” Such words will have a bad result on you and your memory.
But relaxing isn’t enough. To improve your memory, you’ll need to take an active role. Like your body, your memory can be made strong through exercise. Look for opportunities to exercise your memory. For example, if you’re learning a language, try to actively remember a lot of new words.
If you don’t take notice of things actively, you won’t remember them. So, you can make pictures of what you see in your mind every day. For example, don’t just put your keys down! If you want to find them again, make a mind picture of the place where you’re putting them.

Computers can injure(伤害)you. Most other injuries happen suddenly．For example，if you fall off a bike and break your arms, it happens very quickly. But computer injuries happen slowly．
You probably know how to ride a bike safely. Now learn to use a computer safely．

Your eyes 
Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be more than 50 centimeters from the screen. Don’t forget to look away from it sometimes. This gives your eyes a rest．
When you use a computer, the window should be on your left or your right. If it is behind you, the light will reflect on(反射)the screen. If the window is in front of you，the sun and the screen will both shine into your eyes．
Your hands and wrists(手腕)
Hand and wrist injuries can happen because the hands and wrists are moved in the same way hundreds of times. If you use a keyboard for a long time, follow these three rules: 1) Rest your wrists on something.
2) Keep your elbows(肘)as high as the keyboard.
3) Stop sometimes and exercise your hands, wrists and fingers in a different way．
Your back
Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your back or your neck. So you shouldn’t bend your back when you sit. The top part of the screen should be in front of your eyes. Your forearms, wrists, hands and the upper part of your legs should all be parallel(平行)to the floor. If you are sitting for a long time, get up every half an hour and exercise your arms, legs and neck．
Enjoy your computer, but use it safely．

Most people will tell you that they can’t work without a cup of coffee in the morning. Research has shown that a cup of coffee does give a person slight excitement.

Legend said that Kaldi, an Ethiopian, found his goats happier while enjoying coffee plants. Curiously, he tasted the leaves and began to dance around. Whether the Legend was true or not, the discovery of coffee dates back to 800A. D. Soon Arabians were roasting coffee beans. Muslims were drinking coffee to stay awake by 1000 A.D. A merchant from Venice introduced coffee to Europe in 1615. By 1696, the Dutch started growing the coffee bush in Java. By 1723, coffee plants were introduced to the Americans. Today, coffee is the most popular drink in the world.
Caffeine is the major chemical in coffee. It blocks(阻止) adenosine, a chemical that makes you sleepy. People can get a pick-me-up or stimulation(刺激) from the drink. The stimulation does not last long. Caffeine poisoning can occur if more than 400 milligrams of caffeine is drunk in a short period, which is about four to five cups of coffee. Caffeine will also cause sleep difficulty, so it should not be drunk before bed.
Caffeine has many advantages. Studies have shown that it helps improve some skills in elderly women. Women who drank three cups of coffee daily scored higher on memory tests than women who drank one cup of coffee. According to newser.com, one cup of coffee a day protects the brain. Coffee also can help people keep away from many diseases according to webmd.com.
Large amounts of coffee can cause nervousness, worries and a fast heartbeat. However, if you mix coffee with milk, it’s fine. Caffeine can be addictive like any drug. The more you drink, the more you depend on it. For some people, just one cup of coffee a day is OK.

Cats’ sense of smell is very important to their health. Many cat owners have seen a cat smell the food and refuses it. Careful sniffing tells the cat if something is safe to eat.

Cats have a pair of vomeronasal organs(犁鼻器) on the roof of the mouth. When the cat wants to sniff, she will breathe the air in through her mouth. At this moment, she will often squint(斜视) her eyes and maybe even flatten(使…平坦) her ears. This makes her look like she is making faces. The vomeronasal organs will then analyze the smell---almost as if the cat is tasting the smell.
When you come home from outside the house, your cat can smell what you had for lunch and for a mid-afternoon snack. She can smell the people you shook hands with and your neighbour you stopped to talk to and hug. She can smell the grass brought under your shoes as you took a shortcut across the lawn. Your cat’s sense of smell is so good that she can smell difference between a gallon of water with a teaspoon of salt in it and plain water. In comparison, we think of salt as completely tasteless.
Cats have scent glands(臭腺) on each side of the forehead, on the chin, the lips and next to the tail. When your cat rubs up against your hand, your leg, the sofa, and your bed, she is leaving her scent in those things. She will then use her sense of smell to recognize “her” things, people and even other pets in the home.
If you want to have fun with your cat’s sense of smell, take some small bits of different things, such as a bit of chicken, some flowers and some fish. Place each different scent under a piece of paper towel(so your cat cannot see any of them) and encourage your cat to investigate and find what kind of food she likes to eat best.

D．She smells where you were just now.

小题4:What does the word “investigate” mean in the last paragraph?

People have known since ancient times that aspirin（阿司匹林） reduces pain and lowers high body temperature. But that is not all the drug can do. In recent years, it has been used in other ways, too. Small amounts may help prevent a stroke or heart attack. One recent study showed that some people who took two aspirin pills a day had lower rates of colorectal cancer. And, some researchers say aspirin may help patients with colon cancer live longer. So, how did aspirin become so important? The story begins with a willow（柳树）．
2, 000 years ago, the Greek doctor Hippocrates advised his patients to chew on the bark and leaves of the willow. The tree contains a chemical called salicin. In the 1800s, researchers discovered how to make salicylic acid from the chemical. In 1897, a chemist named Felix Hoffmann at Friedrich Bayer and Company in Germany created acetyl salicylic acid. Later, it became the active substance in a medicine that Bayer called aspirin. The "a" came from acetyl. The "spir" came from the spirea plant, which also produces salicin. And the "in" ? That is a common way to end medicine names.
In 1982, a British scientist shared the Nobel Prize in Medicine in part for discovering how aspirin works. Sir John Vane found that aspirin prevents the body from making the natural substances called prostaglandins. Prostaglandins have several effects on the body. Some cause pain and swelling（肿）． Prostaglandins also make the heart, kidneys(肾) and blood vessels work well. So there is a problem. Aspirin works against all prostaglandins, good and bad. It can also harm the inside of the stomach, and sometimes it can cause bleeding.
But a British study released in 2009 suggested that taking another drug with a small amount of aspirin may help reduce the risk of bleeding. If this proves true, it would help thousands of people who are seeking to prevent life-threatening conditions.
