It is 40 meters long and 6 meters wide. This must be the biggest bus you have ever seen. It can carry 1,200 to 1,400 people.
It is China’s new Super Bus. It is going for a test run in Beijing at the end of this year. Some other cities are also interested in running the Super Bus. They hope the traffic problems will be solved.
The Super Bus runs along fixed tracks (固定轨道) . The bus sits on top of two 2.2-meter-tall legs. The legs have wheels at one end. Small cars can drive under the bus, so the Super Bus does not take up road space.
The bus runs on electricity and solar power. It can travel up to 60 km every hour. Its creator, Song Youzhou, says a lot of traffic jams (堵塞) will be reduced.
The Super Bus can do the work of 40 buses. In that way, it can save 860 tons of fuel (燃料) every year, according to Song.
“To build a Super Bus and its track costs less than building subways. Subways are nearly ten times more expensive to build.”Song said.
Some people worry that the Super Bus may not be safe. However, Song says there’s no need for concern. The Super Bus has laser scanners (激光扫描仪) between its legs. The scanners make sure the cars keep a safe distance.

Future and Today
It is well known that everyone has his own dream as well as his own future. 36 I have to say that future is now. That is to say we must treasure every minute now. If we want to have a bright future, we should know how important time is and use it well.
There is an old English saying: “Gain time, gain life.” 37 Time is something that we can’t see or touch, but we can feel it passing by. Time is always with us. When we are at table, time passes; when we play, time goes by unnoticeably. We always say “Time is money”, but time is even more precious(珍贵的)than money, because when money is spent , we can earn it back.
38 So, some of us even say time is priceless(无价的).
We should always remember: future is now. For us students, we should try our best to work hard in order to create a great future of our own. 39 We should do everything before us as soon as possible. And never put off what can be done today till tomorrow.
As we all know , “Time and tide wait for no man.” 40 So from now on, work hard. Tomorrow will be better, and your future will be brighter. Remember: “No pains, no gains.” Today’s hard work is the cause of tomorrow’s harvest.
根据材料内容，从下面五个选项中选出能填入文中空缺处的最佳选项，使短文意思通顺、内容完整，并将其标号填写在下面题号后的横线上。
A. But if time is gone away, it will never return.
B. If you waste today, you will regret tomorrow.
C. But do you know what future really is
D. We should make the best use of every hour and be the master of today.
E. Then what’s time

Soon computers and other machines will be able to remember you by looking at your eyes. The programme works because everyone’s eyes are 11 . So in the future you won’t have to remember a group of numbers when you want to use a machine or take money out of a bank. You’ll just have to look at the machine and it will be able to tell you who you are.
The eye-recognition(眼睛识别) programme has already been tested in shops and banks in the USA, Britain, Spain, Italy and Turkey. Soon it will take the place of all other ways of 12 out who people are. However, scientists are working on other systems. Machines will soon be able to know you from the shape of your face or hand or 13 your smell. We already have machines that can tell who you are from your voice or the mark made by your finger.
Eye-recognition is better than other kinds because your eyes don’t change as you get older, and don’t get 14 like hands or fingers. And twins’ eyes are not the same. So the eye-recognition programme can be up to 94 percent correct. In Britain, it was found that 91 percent of the people who had 15 it said that they liked the idea of eye-recognition.
In the future your computer will be looking you in the eyes. So smile!
