Three Boys and a Dad

Brad closed the door slowly as Sue left home to visit her mother. Expecting a whole day to relax, he was thinking whether to read the newspaper or watch his favourite TV talk show on his first day off in months. “This will be like a walk in the park.” he’d told his wife. “I’ll look after the kids, and you can go visit your mom.”

Things started well, but just after eight o’clock, his three little “good kids”---Mike, Randy, and Alex --- came down the stairs in their night clothes and shouted “breakfast, daddy.” When food had not appeared on within thirty seconds, Randy began using his spoon on Alex’s head as if it were a drum. Alex started to shout loudly in time to the beat(节拍) . Mike chanted “Where’s my toast, where’s my toast” in the background. Brad realized his newspaper would have to wait for a few seconds.

Life became worse after breakfast. Mike wore Randy’s underwear on his head. Randy locked himself in the bathroom, while Alex shouted again because he was going to wet his pants. Nobody could find clean socks, although they were before their eyes. Someone named “Not me” had spilled a whole glass of orange juice into the basket of clean clothes. Brad knew the talk show had already started.

By ten o’clock, things were out of control. Alex was wondering why the fish in the fish bowl refused his bread and butter. Mike was trying to show off his talent by decorating kitchen wall with his color pencils. Randy, thankfully, appeared to be reading quietly in the sitting room, but closer examination showed that he was eating apple jam straight from the bottle with his hands. Brad realized that the talk show was over and reading would be impossible.

At exactly 11:17, Brad called the daycare center(日托所).“I suddenly have to go into work and my wife is away. Can I bring the boys over in a few minutes?” The answer was obviously “yes” because Brad was smiling.

The pupils of Grangetown High have been busy getting to know their newest and tallest classmate — a 7-meter-tall giraffe outside their school.

The giraffe is a huge sculpture (雕像) made by a local artist. The school's headmaster noticed the sculpture in the artist's garden as he drove past one day, and thought it would be perfect for his school. “I knew everyone would love it,” he said, “because our basketball team is known as the Grangetown Giraffes, and they wear giraffes on their shirts. So I asked them to write a letter to the artist, asking how much it would cost to buy the giraffe. He was very kind and got it ready to deliver (递送) in six weeks — all for nothing! It was expected to arrive one Sunday morning, so that the pupils would see it when they got to school on Monday — at that time they had no idea that we were getting it.”

The artist, Tom Bennett, was a university professor (教授) of chemistry before he left that job in 2006 and only took up metalwork a couple of years ago. “I've always drawn pictures,” he said. “I can even remember doing it on my first day at school — I drew a horse. I wanted it to be the best horse picture ever, but I don't think I succeeded.” Tom's first metalwork was a bicycle for two that he and his wife could go cycling on together. “It was the most uncomfortable bike ever created,” he said, “so I gave up making bicycles and went into sculpture instead.”

Meanwhile the pupils at Grangetown High are very happy with their new classmate. “We're going to hold a competition to give it a proper name,” said one girl. “Everyone likes the expression on its face, so perhaps that will give us some ideas.”

Some unwelcome visitors from North America have been turning up in the waters off the coast of Great Britain.

North American lobsters (龙虾) have been found in the North Sea (between Great Britain and Northwest Europe), far from their own habitat. The lobsters usually live along the eastern coast of Canada and the United States.

It is impossible that the lobsters could have made the 5,600-kilometre journey on their own. They were probably brought to Britain and then got away from containers. Some of the lobsters that were caught had elastic bands (松紧带) holding their legs shut, like lobsters that are kept in containers in stores or restaurants.

Many may have been “set free” from some ships passing through the area. Sometimes passengers order a live lobster from a tank in the dining room and then ask the waiter to throw it overboard instead of cooking it.

According to official records, 26 North American lobsters have been caught in waters off Great Britain since 1988. However, it is believed many more have been found but not reported.

It is against the law to let North American lobsters come into British waters. If they settle down in European waters, it would be bad for the local lobsters. The two live in the same place and eat the same food. But North American lobsters are larger, stronger and more aggressive (好斗的) than European lobsters, and they produce young more quickly.

As a result, they could take food and space away from the local lobsters, and from other types of shellfish that live in the same area. These lobsters may also carry diseases that could harm the local lobsters.

1.Those unwelcome lobsters _____.

A. could travel 5,600 km a day on their own

B. used to live in waters off Great Britain

C. would soon disappear in British waters

D. might have escaped on the way to Britain

2.What can we learn about European lobsters?

A. They are growing too fast to be kept under control.

B. Shellfish often take away their food and space.

C. They are easily harmed by North American lobsters.

D. People become ill easily if they eat these lobsters.

3.The author's purpose of writing the text is most likely to _____.

A. discuss B. report

C. advertise D. introduce

According to a team of researchers, an animals' ability to perceive(感知)time is linked to their pace of life.

"Our results lend support to the importance of time perception in animals where the ability to

perceive time in a very short time may be the difference between life and death for fast moving

creatures." commented lead author Kevin Healy from Trinity College Dublin.

The study was done with a variety of animals using a phenomenon based on the maximum speed of flashes of light an individual can see before the light source is seen as constant. Dogs, for example, have eyes with a refresh rate higher than humans.

One example of this phenomenon at work, the authors say, is the housefly and its ability to avoid being hit. The research showed flies "observe motion in a shorter time than our own eyes can achieve," which allows them to avoid being hit.

Professor Graeme Ruxton of the University of St Andrews in Scotland, who worked jointly(共同地) on the research project, said in a statement, "Having eyes that send updates to the brain at much higher frequencies than our eyes do is of no value if the brain cannot process that information equally quickly. Thus, this work highlights the impressive abilities of even the smallest animal brains. Flies might not be deep thinkers, but they can make good decisions very quickly."

In comparison the tiger beetle(虎甲虫)runs faster than its eyes can keep up, basically becoming blind, which requires it to stop periodically to re-evaluate its prey's(猎物)position.

Our results suggest that time perception offers an as yet unstudied dimension along which

animals can specialize and there is considerable range to study this system in more detail.

1.What is the research mentioned in the passage mainly about?

A. Pace of life of animals. B. Time perception of animals.

C. Lifetime of small animals. D. Impressive abilities of animals.

2.Why can houseflies avoid being hit?

A. They can think very deeply before they act.

B. They can fly much faster than their eyes can keep up.

C. They can process the information as quickly as they receive it.

D. They can send information to brain more quickly than to their eyes.

3.What will a tiger beetle have to do to catch a moving prey?

A. Try to run as fast as it can. B. Prevent itself from becoming blind.

C. Slow down to gain its time perception. D. Stop occasionally to spot the prey again.

Eyesight plays a very important role in our daily life. Every waking moment, the eyes are working to see the world around us. Over forty percent of Americans worry about losing eyesight, but it's easy to include steps into our daily life to ensure healthy eyes. Here are five suggestions for a lifetime of healthy eyesight:

·Schedule yearly exams. 1. Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check. The good news is that millions of children now can have yearly eye exams and following treatment, including eyeglasses.

·Protect against UV rays (紫外线). Long?term stay in the sun creates risk to your eyes. No matter what the season is, it's extremely important to wear sunglasses. 2.

·3. Two thirds of Americans spend up to seven hours a day using computers or other digital products. This frequent eye activity increases the risk for eye tiredness. Experts recommend that people practice the 20/20/20 rule: every 20 minutes, take a 20?second break and look at something 20 feet away.

·4. As part of a healthy diet, eat more fruits and vegetables each day. Vitamins (维生素) C and E help protect eyesight and promote eye health.

·Practice safe wear and care of contact lenses (隐形眼镜). Many Americans use contact lenses to improve their eyesight. While some follow the medical advice for wearing contact lenses, many are breaking the rules and putting their eyesight at risk. 5. Otherwise, you may have problems such as red eyes, pain in the eyes, or a more serious condition.

A.Give your eyes a break.

B.Parents usually don't care about their own eyesight.

C.They can properly protect your eyes.

D.Stay in good shape by taking more vitamins.

E.Have your eyes checked as early as possible.

F.Always follow the doctor's advice for appropriate wear.

G.Eat your greens.
