Like many Czechs (捷克人), Lukáš Berný, 38, enjoys going out to the pub with his friends for conversation and a few beers. “I don’t drink every day,” he says. “I think about three times a week. When I go out, I usually have five to six beers at a time, about the same as my friends.” The beers are half-liters, or 500ml each.

If a half-liter of four-percent beer contains 16g of pure alcohol(酒精), Berný and his friends are drinking 80 to 96 grams of pure alcohol on each outing. The Czech Republic’s National Institute of Public Health, however, suggests that men take in fewer than 24g of pure alcohol per day; women, fewer than 16g.

Medical experts in over 40 countries around the world have agreed that drinking “too much” can cause harm. What they can’t seem to agree upon is just how much is “too much.” National safety levels are quite different, from a limit of 10g a day in the Netherlands to Denmark’s 60g.

There are a number of reasons for this. Dr. Larry Altshuler, a medicine expert for the Cancer Treatment Centers in Tulsa, explains that while everything is based on research, “Every group, race, and gender responds to alcohol differently.”

Also, researchers aren’t using the same models or methods. He adds, “It can be like apples and oranges. How do you measure alcohol? Units, drinks, bottles or cans? What’s the alcohol content(含量)? Is it light or heavy?” While a half-liter of four percent beer contains 16g of pure alcohol, a half-liter of five percent lager contains 20g.

Constance Scharff, a director of Addiction Research at Cliffside Malibu Treatment Center in California, says she believes the reason “is largely cultural.” “But the evidence is clear that the more you drink, the more likely you are to develop alcohol-related health problems.”

1.The first paragraph is intended to ________.

A. describe the habit of Lukáš Berný

B. advise readers to live a carefree life

C. direct readers’ attention to the topic of drinking

D. support the popular belief that Czechs fancy drinking

2.The underlined word “this” in Paragraph 4 refers to ________.

A. the alcohol limit for Czechs

B. the measurement of alcohol content

C. the concern over the harmful effects of drinking

D. the difference in national safety levels of alcohol

3.According to the passage, what might determine the national safety standards of alcohol?

A. Drinking length and alcohol containers.

B. Drinking atmosphere and alcohol quality.

C. Cultural differences and measuring methods.

D. Research results and alcohol-related health problems.

4.What may be the best title for the passage?

A. How Can Drinking Be Safe?

B. How Much Alcohol Is Too Much?

C. Why Does Alcohol Do Harm to Health?

D. What Harm Will Alcohol Cause to Us?

Who could have imagined that a treadmill(跑步机)on wheels would one day become a thing?!? Lopifit is an unusual means of transportation that allows you to power an electric bicycle by walking on a treadmill.

Lopifit founder Bruin Bergmeester says it all started when he asked himself the question “How can I use a treadmill outdoors?” He finally came up with a new design, adding an electric motor, and the Lopifit was born. It’s similar to an electric bicycle in that the motor only works when the rider puts power in as well. The Lopifit senses when you walk on the treadmill and uses the motor to turn a drive chain at the back of the treadmill, helping you reach a top speed of 17 miles per hour.

To use the Lopifit, simply turn on the battery(电池)and use your foot to slide the treadmill backwards and start the motor. Then get on and enjoy the ride! If you need speed, just walk on the treadmill, and if you want to coast(惯性滑行), all you have to do is stay still and admire the view. To stop, you have two hand breaks.

The Lopifit first hit the streets in 2014 and, unsurprisingly, became a hit overnight. That was actually quite challenging for the company, because it started getting calls for orders, but it was nowhere near ready for mass production. The unique treadmill bicycle could be bought this year, and Lopifit is struggling to keep up with demand, although the price is up to $2,115.

Some people consider this means of transportation stupid and unnecessary, although there is a very loyal fan-base of so-called Lopifitters. They simply believe that if you’re going to walk, you might as well do it the old-fashioned way.

But the Lopifit does have the special advantage of helping you “walk” really fast without much effort, or walking at cycling speed, if you will.

1.Lopifit is an electric bicycle which ________.

A. can be powered by the drive chain

B. can work without an electric motor

C. works when you walk on the treadmill

D. stops when you slide the treadmill forward

2.What is Paragraph 3 mainly about?

A. The design of a Lopifit.    B. The function of a Lopifit.

C. The structure of a Lopifit.    D. The operation of a Lopifit.

3.What is probably the author’s attitude towards Lopifit?

A. Confident.    B. Concerned.

C. Curious.    D. Doubtful.



“Don’t get discouraged, Hallie,” Kathy said, comforting her with a hug. “It sounds as if you have a bit of a mystery to solve. Maybe you should do a little spying on Maya.”

Feeling better, Hallie put on her scuba gear(潜水服)again and waited. Maya, the dolphin, had been swimming playfully, but suddenly she threw herself to the back of the tank where the filter box(过滤箱)was located. She stuck her nose down behind the box and then swam away.

Hallie followed Maya. “What was she doing here?” she wondered. When she looked behind the box, her question was answered. She swam back and saw Maya was in front of Kathy with a comb in her mouth waiting for her treat.

“Maya! Where did you get that?” demanded Kathy, taking the comb and throwing her a fish.

“I know,” declared Hallie, handing Kathy a handful of items, “I followed her to the filter box and these are what I found.”

From the look on Kathy’s face, Hallie knew everything was beginning to come to light.

“Do you remember the other day you said that Maya really liked her treats?” asked Kathy.“Well, I think this was more than a training exercise for Maya. Every time you found something in the tank, that meant one less fish for Maya. She couldn’t bring all the items to me at once, so she found a hiding place for them. That way you came up empty-handed, but Maya would always get her treat.”

“Okay, Maya,” said Hallie facing the dolphin, “you win! The treats are all yours.”

Maya dived down, and then jumped out of the water, turning herself over in midair. Shaking their heads in disbelief, Hallie and Kathy reached for the fish. Maya deserved the treat.

1.What was the “mystery” in the story?

A. The secret of Maya’s finding the items.

B. The secret of Hallie’s winning the game.

C. The reason for Maya’s liking her treats.

D. The reason for Hallie’s spying on Maya.

2.Maya hid the items because she considered Hallie as a ________.

A. spy

B. competitor

C. playmate

D. trainer

3.At the end of the story, Hallie and Kathy thought Maya was ________.

A. energetic

B. genuine

C. loyal

D. smart

One day a lady saw a mouse running across his kitchen floor. She was very afraid of mice, so she ran out of the house, getting on a bus and went to a nearby shop. Here she bought a mousetrap (老鼠夹子) and was advised to put some cheese in it. The lady went home with her mousetrap, and could not find any cheese. She had no choices but to cut a picture of some cheese out of a magazine and put it in the trap. Surprising, the picture of the cheese is quite “successful”! When the lady came down to the kitchen in the next morning, she found a picture of mouse in the trap besides the picture of the cheese!
