Are you looking for something to do? You might like to try one of these four experiences.

Crocodile watching

Do you fancy getting up close to some of the most terrifying animals on earth? Crocosaurus Cove, in Darwin (Australia) has the “Cage of Death”. It’s an enclosure(围场) that’s lowered into a pool. This gives you a 360 degree view of a crocodile as it’s being fed. The cable broke once and the cage sank to the bottom, but they’ve fixed it since then.

Edge walk

How about walking along the edge of a building several hundred meters up in the air? If that sounds like fun, head off to the CN Tower in Toronto (Ontario, Canada). Built in 1976, the tower is 553.33 meters tall.

The Edge walk consists of a 20-30 minute stroll along a 1.5 meter wide platform that runs around the tower’s restaurant roof. During the walk, you’re encouraged to lean forwards as you look over Toronto’s skyline (轮廓线).

Plastic ball rolling

Do you fancy rolling down a hill in a plastic ball?

Plastic ball rolling is popular all over the world, but the place to give it a go is in Rotorua (New Zealand). Brother David and Andrew Akers came up with the idea in 1994. A typical orb (球) is about 3 meters in diameter, with an inner orb size of about 2 meters. There’s no brake or steering mechanism, but the inner layer of the plastic ball helps absorb the shock.

Volcano bungee jumping

If you’re looking for the adventure of a lifetime, how about going bungee jumping off a helicopter into the crater of a live volcano? As part of the jumping, a helicopter ride takes you to the Villarreal volcano, one of the most active in Chile. Once you’re at the drop zone, you leap off the helicopter and fall into the volcano. Finally, you enjoy the ride back to the airport flying at 130kph.

Dyslexia is a problem that restricts the ability to recognize words and connect sounds with letters when people read. People with this learning disorder may also have problems when they write. Dyslexia is not related to eyesight or intelligence. The problem involves areas of the brain that process language. Brain scientists are studying whether they can predict which young children may struggle with reading to provide them with early help. John Gabrieli at the Massachusetts Institute of Technology is leading the study of five-year-olds in about twenty schools in the Boston area.

They studied in the schools with kindergartens.And for all the children joining in the study, they give them a brief set of paper-and-pencil tests to look at which children appear to be at some risk for struggling to read. So far, fifty of them have been examined in a scanner, a special machine, to show brain activity. Written tests are not always able to identify dyslexia or other problems, while brain scans may offer a more scientific way to identify problems. And with reading problems, early identification is important. When it comes to helping children overcome reading difficulties, the younger the child, the more effective they are.

Reading problems are not usually identified until a child is in the third or fourth grade. The later children are recognized as poor readers,the less treatment can help. And, as Professor Gabrieli points out, poor reading can make education a struggle. Reading is everything. Even math and science have textbooks.

While the children are given tasks related to reading, the brain scans measure the extent to which certain parts of the brain become active while the children do the work. The scientists say they are pleased with early results from the study, but have a long way to go.

If you want a little extra security against thieves stealing your bicycle, designer Dennis Siegel has designed a solution. The RFID Bikealarm is attached to the seat on a bicycle and gives off an alarm when it senses movement.

“The RFID Bikealarm is meant to be a useful add-on to mechanical bicycle locks because it greatly extends the range of protection with only a few components,” Siegel explains on his website. “It is low-cost, durable and easy to use.”

The Bikealarm was designed as part of Siegel’s Bachelor’s degree thesis at the University of the Arts Bremen in Germany. The device will scare off any would-be thieves the moment they begin to steal the bicycle to which it is attached. It is able to continuously sense the environment to distinguish between specific events, for instance a passing tram / car and a serious theft.

Siegel created a working model of an alarm that would sound when it sensed movement, but wasn’t initially sure how it would be best attached to a bicycle. “I decided to mount it to the rails of the seat because it allows for comfortable interaction and the position is less obvious as it looks like a small repair kit,” he says.

Siegel chose to use RFID technology rather than Bluetooth to keep the costs down. Siegel explains that the most difficult aspect of creating the alarm was to get the electronic circuit down to a small enough size.

The device runs off a kind of battery that can be charged by USB within 2 hours and lasts for a few days with normal use. As the Bikealarm is only at development stage, Siegel hasn’t signed any agreements to put it on the market.

B. It is very difficult to use.

C. It uses a kind of battery for power.

D. It depends on Bluetooth technology.

4. It can be inferred from the last two paragraphs that ______.

A. the electronic circuit is a little larger

B. it’s very easy to make a Bikealarm

Professional footballers have worryingly poor teeth that could be affecting their performance on the football ground, say dentists. Their study on players at eight clubs in England and Wales, in the British Journal o f Sports Medicine, showed nearly 4 out of 10 had cavities (蛀牙) and that athletes often had worse teeth than the general population. Regularly taking sugary foods is one possible explanation.

The dentists, from the International Centre for Evidence-Based Oral Health at University College London, examined 187 players' sets of teeth. They found 53% had dental erosion (腐蚀), 45% were bothered by the state of their teeth and 7% said it affected their ability to train or play. Around 40% had cavities, compared with 30% of people of a similar age in the general population.

Prof Ian Needleman, one of the researchers, said: "These are individuals who otherwise invest so much in themselves so it’s a surprising finding.

"There are two main groups - some have a catastrophic effect, they have very serious disease that stops them in their tracks and they cannot play or train.

"There Il be others experiencing pain affecting sleep or sensitivity every time they take a drink. "

At this level of athlete, even small differences can be quite telling.

Nutrition is one of the primary suspects with having too many sugary or acidic foods during training potentially accounting for cavities and erosion. A lot of air in the mouth during exercise can also dry it out so there is less protection.

While these findings are worrying, clubs are attaching greater importance to dental health and educating their players. According to Stijin Vandenbroucke, head of medicine and sports science at West Ham United, oral health is an area where many athletes have greater problems than the general population and there are clear benefits of oral disease prevention for athletes and clubs.

D. Having little education of oral disease prevention.

3. These findings are worrying clubs because____.

A. footballers aren’t willing to give up sugary or acidic food

B. they've spent much on their players' oral disease prevention

C. footballers have more serious tooth problems than the public

D. players' oral disease may lead to bad performance in games

4. This passage is most probably taken from____.

A. a dentist's diary B. a sports newspaper

Some experts feel that cars are certain to fall into disuse. They see a day in the not-too-distant future when all cars will be deserted and made useless. 1. They hold that the car will remain a leading means of city travel in the foreseeable future.

The car will undoubtedly change greatly over the next 30 years. It should become smaller, safer, and more practical, and should not be powered by the gas engine. 2.

Unless changes take place in the power system, the car in the future will still be the main problem in city traffic jams. 3.

When the car enters the highway system, a small arm will drop from the car and connect with a rail, which is similar to hose(软管) powering subway trains electrically. Once joined to the rail, the car will become electrically powered from the system and control of the car will pass to a central computer. 4.

The driver will use the telephone to dial instructions about his position and the place he heads for into the system. The computer will find the best way and reserve space for the car all the way to the correct exit from the highway. ____5. It is believed that an automated highway will be able to deal with 10,000 cars per hour, compared with the 1,500 to 2,000 cars that can be carried by a present-day highway.

A. The driver will be free to relax and wait for the call that will warm him of his coming exit.

B. Other experts however think the car is here to stay.

C. The car of the future should be far more pollution-free than present types.

D. There will be plenty of policemen on the highway to control the traffic.

E. One suggested solution to this essential problem is the automated (自动的) system which seems to hold water.

F. The computer will then monitor all the car’s movements.

G. All of the experts don’t know what will happen in the future.

I wrote my first poem at the age of seven and showed it to my mother.She read and cried, “Buddy, you really wrote a beautiful poem!”

Shyly but , I said yes.She poured out her . “It was nothing short of talent!”

“What time will Father be home?” I asked.I could hardly wait to my work to him.I spent quite some time for his arrival. I wrote the poem out in my finest handwriting, drew a fancy border around it and I placed it right on my father’s plate on the dining table. My father had begun his motion-picture career as a writer. I was sure he would be able to my poem.

At almost 7 o’clock my father burst in. He seemed . He circled the dining-room table, complaining about his employees.

Suddenly he paused and glared at his plate. “What is this?” He was reaching for my poem.

“Ben, Buddy has written his first poem!” my mother began. “And it’s beautiful, absolutely amaz…”

“If you don’t mind, I’d like to decide for myself.” Father said.

I my head as he read that poem. It was only ten lines. But it seemed to take hours. Then I heard him dropping the poem back on the table. Now came the moment of .

“I think it’s terrible,” he said.I couldn’t look up. My eyes were getting .

“Ben, these are the first lines of poetry he’s ever written,” my mother was saying. “He needs .”

“I don’t know why.” My father held his ground. “Isn’t there enough awful poetry in the world already?”

I couldn’t it another second. I ran from the dining room crying. Up in my room I myself on the bed and cried the worst of the out of me.

That may have been the end of the story, but not of its for me. I realized how fortunate I had been. I had a mother who said, “I think it’s wonderful!” and a father who drove me to hear with “I think it’s .”

Every one of us needs that mother force, from which all flows; and yet the mother force alone is incomplete. It needs the balance of the force that , “Watch. Listen. Review. Improve.”

Those voices of my childhood ring in my ears through the years, like two opposing winds blowing me. Between the two poles of and doubt, both in the name of love, I try to follow my true course.
