While flying, a bat(蝙蝠)makes a sound which hits things and comes back to its ears.In this way it’s able to know ________ the things are and avoid bumping into them.
Humans have always dreamed of finding a way to leave traffic jams(交通堵塞)behind.Well, dream no longer.The flying car and pod car(豆荚车)can help cut down on traffic jams.
The world’s“first flying car”, called the Terrafugia Transition, has made its first flight in the skies of the US.It can fly 640 km through the air without adding more gas, the car maker, Terrafugia Inc, says.
As a light airplane, it is not easy for the Terrafugia Transition to fly in poor weather.However, it has the advantage of being able to continue the journey by road if conditions take a turn for the worse.
This is the first proven flying car with foldable wings.These allow it to perfectly transfer from air to road.
However, there are a few problems.The car/plane, which is expected to go on sale as early as 2011, will cost about $194, 000(1.33 million yuan).Drivers will also need a driver’s and pilot’s license.
For those afraid of heights, or who don’t want to fly, the pod car is a great way to travel.Imagine using a button to stop the small pod-shape car.The doors open, you climb into the passenger seat, and enter your personal number.Minutes later, the doors slide open and you have reached the place where you’re going.
Cities around the world are looking into pod-car systems, as pod cars do not need human drivers.They are designed for one person or small groups traveling together.Passengers simply type their place into the pod car’s computer and the pod car takes them directly there.
Because pod cars do not make unnecessary stops and use electricity, they save a lot of energy and do not pollute the air.Pod cars also provide passengers with faster service and more privacy than a subway or bus.
While flying cars and pod cars may be a dream available to a few, many humans are still dreaming bigger dreams, such as teleportation(瞬间位移术).It is most widely found in works of science fiction.
Telep ortation is a method of transportation, in which, objects or information are dematerialized(使消失), and then recreated in another place.Maybe one day, teleportation could become a reality and people could avoid traffic jams for ever!

If you watch the sky about an hour after the sun goes down, you may see some "movingstars".But they're not real stars.They are man-made satellites.And the biggest of all is the International Space Station(ISS国际空间站).
From now until July is the best season to watch the ISS flying over the earth, and people can see it just with their eyes.The ISS is the biggest man-made satellite because scientists want to live on it.They think that the best way to learn more about space is to live there.
When the space station is finished, it will be like a city in space.People will stay and study there with many of the things they have at home.Laboratories, living rooms and power stations are being built.The ISS is the most ambitious(雄心勃勃)and expensive space program ever.
Billions of dollars are being spent on it every year.
Scientists hope that the ISS will be a stepping-stone(垫脚石)for future space exploration.
"The ISS will help us better understand the human body, explore space and study the earth.It can help us make life on the earth better," said Kathryn Clark, an ISS scientist.
China is not an ISS country, but it has helped with some of the experiments.China sent some rice up to the ISS to find out what space would do to it.
The ISS is not finished yet.More than 100 parts need to be put on.Scientists hope it will be finished as soon as possible.After it's finished, more than 90% of the world's population will be able to see the Space Station.So keep looking up, and maybe you'll see it get bigger.
