Car companies are developing vehicles that will plug into electric sockets，just like many laptops，digital cameras，cell phones and Mp4 do．Called“plug-in vehicles”，these cars will get most of their power from electricity. Their drivers won't have to stop at gas stations as often as usual．
The technology is more than just cool. In our car-filled world，plug-in vehicles could reduce the amount of gas we use，which keeps rising in cost now and then. Besides，driving around in these vehicles may even help the environment．Gas-burning cars produce a lot of greenhouse gas，which causes globe warming.
The first company-produced plug-in vehicles could hit the roads by 2010. But engineers still have a lot of work to do to make the technology practical and inexpensive．
Batteries(电池) are the biggest challenge. In the plug-in-vehicle world，Li-ion(锂离子)batteries are getting the most attention．These batteries can store a large amount of energy in a small package，and they last a longer time between charges．Li-ion batteries can fit laptops，cell phones，heart instruments and other similar pocket ones.
But because cars are so big and heavy, it would still require a suitcase-sized Li-ion batteries to power about 12km of driving．What's more，the batteries are much expensive．
“A car filled with batteries could go a long distance，”says Ted Bohn, an electrical engineer in Chicago．“But it couldn't pull any people．and it would cost $100,000．”
So researchers need to work out how to make batteries smaller and cheaper，among other questions.
“The answers don't exist yet，”Bohn says，“As a kid，I thought someone someplace knows the answer to everything．All of these questions haven't been decided．That's what engineering is about-making a guess，running tests and getting fine results．”
72．The passage mainly talks about        of a new car
A．the developing    B．the speed    C．the appearance D．the batteries
72．Which is true according to the passage?
A．The“plug-in vehicles”will use electricity completely as driving power．
B．The new technology will help protect our environment．
C．The technology of using electricity as driving is quite practical now．      
D．The biggest challenge of the new technology is that it will cost us more energy．
74．How does Bohn feel about the future of the technology according to the last paragraph?
A．Confident    B．Puzzled．    C．Worried． D．Disappointed．
75．According to the passage，the new technology is facing the following problems except that ．
A．the new technology cannot come into use at present
B．the cost of the new technology is quite high
C．the government won't support the technology
D． the size of the batteries is too big at present

That year , in the local school, there was a new math teacher, as well as some new pupils. One of the new kids was the stupidest child anyone had ever seen. It made no difference how quickly or how slowly they tried explaining numbers to him; he would always end up saying something enormously stupid. Like two plus two was five, seven times three was twenty-seven, or a triangle had thirty corners……
Before this boy arrived, math lessons had been the most boring of all. Now they were great fun. Encouraged by the new teacher, the children would listen to the pieces of nonsense spouted by the new kid, and they would have to correct his mistakes.
Whenever the new teacher asked questions, the stupid kid would stand up but made the wrong answers, the other students all wanted to be the first to find his mistakes, and then think up the most original ways to explain them. To do this they used all kinds of stuff : sweets, playing cards, oranges, paper planes, etc. It didn’t seem like any of this bothered the new kid.
However, Little Lewis was sure that it was bound to make him feel sad inside. Lewis was sure he would see him crying. So, one day, he decided to follow the new kid home after school. On leaving school, the new kid walked a few minutes to a local park, and there he waited for a while, until someone came along to meet him……
It was the new teacher!
The teacher gave the new kid a hug, and off they went, hand in hand. Following from a distance, Lewis could hear they were talking about math.
【小题1】根据短文第二三段描述，可知这位新老师的工作很有创造性，故选A。
【小题2】根据短文最后一段Following from a distance, Lewis could hear they were talking about math.描述，可知选B，这个所谓的最蠢的学生其实比其它学生知道的多。
【小题3】根据Lewis was sure he would see him crying. So, one day, he decided to follow the new kid home after school.描述，可知选B。
【小题4】联系上文To do this they used all kinds of stuff :可知选C。
【小题5】The math lessons became interesting again because of the new teacher’s ___________.
