Many people have long dreamed of being able to fly around as simply as riding a bicycle. Yet the safety and strength of a flying bike was always a big problem. Over the past 10 years, developments in technology have moved the dream of personal flying vehicles closer to reality. Now, two groups of inventors say such vehicles may be available very soon. Grant Stapleton from Malloy Aeronautics says the Hoverbike, which is able to get in and out of small spaces very quickly, will be a truly personal flying vehicle. "It can be moved across continents very quickly because it can be folded and packed," he adds. Mr. Stapleton says safety was the company's main concern when developing the Hoverbike. He ays the designers solved the safety issue by using overlapping rotors to power the vehicle. The company is testing both a one-third size model and a full-size prototype of the Hoverbike. Inventors say their Hoverbike will most likely be used first by the police and emergency rescue teams. In New Zealand, the Martin Aircraft Company is also testing a full-size prototype of its personal flying bike, called Jetpack. It can fly for more than 30 minutes, up t0 1,000 meters high and reach a speed of 74 kilometers per hour. Peter Coker is the CEO of Martin Aircraft Company. He said Jetpack "is built around safety from the start, " In his words, "reliability is the most important part of it. We have safety built into the actual structure itself, very similar to a Formula One racing car. " Jetpack uses a gasoline-powered engine that produces two powerful jet streams. Mr. Coker says it also has a parachute that can be used should there be an emergency. "It opens at a very low altitude and actually saves both the aircraft and the pilot in an emergency," he adds. What make(s) flying vehicles seem practical now? A) Modem technology. B) New safety rules. C) Love of cycling. D) Public concerns.

The Red Panda isn't much bigger than an average size house cat. At first you may think it's a bear because of its name. They're actually a member of the raccoon family which you can tell if you look at their appearance. The Red Panda has a long bushy tail that is useful in two ways. It helps them stay balanced when they are high up in the trees and it keeps them warm in cold weather. Their fur is thick and reddish brown, which may be why they're known as the fire fox. The Red Panda can be found in forested mountains. They're originally from the forested mountain in the Himalayas in India, Nepal and Southern China. Bamboo is the most important part of their diet. They only eat the young leaves and shoots of a bamboo plant. Red Pandas have a very low metabolic rate in order to deal with their low energy diet and cool environmental temperatures. They're very shy and gentle and don't hang around the wild too much during the day. If they feel endangered, they'll stand on their back legs and make a hissing sound. Red Pandas are good climbers and spend most of their time living mainly in trees. Their claws are very strong and help them hold onto the branches. They sleep in an unusual way by curling up tightly and wrapping their tails around their heads while sitting on a branch. Sometimes they'll sleep with their head beneath their chest and behind their back feet. This is the same position as an American raccoon sleeps. The Red Panda holds onto the branches with its _ . A) tail B) fur C) back legs D) claws

Q: Most people around the world are right-handed. This also seems to be true in history. In 1799, scientists studied works of art made at different times from 1,500 B.C. to the 1950s. Most of the people shown in these works are right-handed, so the scientists guessed that right-handedness has always been common through history. Today, only about 10% to 15% of the world's population is left-handed. Why are there more right-handed people than left-handed ones? Scientists now know that a person's two hands each have their own jobs. For most people, the hand is used to find things or hold things. The right hand is used to work with things. This is because of the different work of the two sides of the brain. The right side of the brain, which makes a person's hands and eyes work together, controls the left hand. The left-side of the brain, which controls the right hand, is the centre for thinking and doing problems. These findings show that more artists should be left-handed, and studies have found that left-handedness is twice as common among artists as among people in other jobs. No one really knows what makes a person become right-handed instead of left-handed. Scientists have found that almost 40% of the people become left-handed because their main brain is damaged when they are born. However, this doesn't happen to everyone, so scientists guess there must be another reason why people become left-handed. One idea is that people usually get right-handed from their parents. If a person does not receive the gene for right-handedness, he / she may become either right-handed or left-handed according to the chance and the people they work or live with. Though right-handedness is more common than left-handedness, people no longer think left-handed people are strange or unusual. A long time ago, left-handed children were made to use their right hands like other children, but today they don't have to. The best title for this passage is _ . A) Scientists' New Inventions B) Left-handed People C) Which Hand D) Different Brains, Different Hands

Every person leaves a footprint. That's what I learnt when I started to work as a private investigator 10 years ago.People pay restaurant bills with their bank card,check into hotels or travel around. In every case,they leave a trace.And because of this,I'm able to track them down even when they don't want to be found. The first thing I do when I want to find out where someone is staying is to go to the neighbourhood where he used to live.It's human nature to tell stories--which is why neighbours will tell me all they know when I ring at their houses.Sometimes,someone even talks about his friend's dishonesty.Then I produce a pattern of my subject's life:if he likes to have a holiday in Spain or in Italy,if he prefers two- or three- star hotels and where he might hide his assets .When I've got this life pattern,I start my rescarch. Nine times out of l0,I find the people I'm looking for.I once investigated a lorry supplier who owed PS500,000 to a subcontractor .The subcontractor wanted to find out if it was worth bringing charges against the supplier.I found out the supplier had moved assets to his son,who founded a new company offering the same product.It was a11 done within the law.There was no money to be got from that operation. However, I asked the son if I could speak to his father and he told me that his parent was on a long holiday in Spain and wouldn't be back for a while.It didn't take me long to find out that the father wasn't in Spain. I went back to the son and this time he told me that his father might be in Bulgaria,and I found him doing winter sports in a beautiful mountain area.He was 1iving in a big house on a 1arge piece of land he had bought for ie 400,000.This was exactly the kind of asset my customer was loooking for. We learn from the text that a private investigator is one who _ . A) follows people reports on what they do B) helps people start businesses C) gives advice to people about the law D) settles arguments between companies
