Unlike traditional commercials, Public Service Advertisements（PSA）are primarily designed to inform and educate rather than sell a product or service. The goal of a PSA is not to make a big sale, but rather to change public opinion and raise awareness for a problem.

Smokey Bear has been a recognized symbol of the protection of America’s forests from fire. It is created to educate the public about the dangers of wildfires. Smokey Bear was started in 1944 with the slogan, “Smokey Bear Says—Care will prevent 9 out of 10 forest fires”. Smokey Bear’s later slogan,  “Remember! Only You Can Prevent Forest Fires”, was created in 1947 by the Advertising Council in America. In April 2001, the message was changed to “Only You Can Prevent Wildfires”.

The wildfire prevention campaign with Smokey Bear is one of the longest and most successful campaigns in advertising history. The Advertising Council often was in partnership with other organizations and groups to create various advertising for Smokey Bear since 1944.

The Advertising Council teamed with Walt Disney Company to create a series of PSAs. The ads feature（以···为形象）characters form the classic film Sleeping Beauty and aim to reach parents and children. The lovely Bambi also appeared in the advertisements. Mickey Mouse is much more popular throughout the country.

Those PSAs, which appear on television, on the radio, in the newspaper and on the website continue to remind Americans about the importance of wildfire prevention have helped to reduce the number of acres burned annually by wildfires. According to recent survey, Smokey Bear and his famous words of wisdom “Only You Can Prevent Wildfires” are recalled by 3 out of 4 adults.

In addition to the PSA campaign, Smokey Bear has his own U.S. postage stamp and website for more information about wildfire prevention. From the website, you can also learn all about wildfires and how we can protect our forests.

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

Jeanne Calment, a French woman, become a record breaker on 17 October 1995, when at the age of 120 years and 238 days, she became the longest-lived human being on record. A Japanese man died in 1986 at the age of 120 years and 237 days.

Jeanne Calment lives in a small old people’s home in the south of France, her husband, her only child and her grandson have all died. She is nearly blind and deaf and is always in a wheelchair, but her doctor describes here as being “more like a 90-year-old in good health” than someone of 120. She still has a lively sense of humor. When asked on the 120^th birthday what she expected of the future, she replied, “A very short one.” She also remarked that she thought the good Lord had forgotten all about her.

So what is the key to a long life? According to some doctors, diet, exercise and no smoking are the three important factors. Jeanne Calment has followed two of the tips. She has always eaten a healthy diet, and she used to do exercises every day until she broke her leg at the age of 115. However, until recently she drank two glasses of strong red wine a say, and she does smoke (now only a little). Besides, Jeanne Calment might have got very good genes from her parents. Her father lived to the age of 94 and her mother to 86.

A local lawyer bought her house when she was 80 under an agreement that he would pay her some money every year until her death. It must have seemed a good move at the time, but so far the lawyer has paid her at least three times the value of the house. Every year on her birthday Jeanne Calment sends him a card saying: “Sorry, I’m still alive!”

阅读下面短文并用英语回答问题，（请注意各小题后面的词数要求）。

[1]I don't know about you, but I look a lot older than I really am. Now I know I could solve much of that by coloring my hair with some product like "Just for Men", but I refuse to go there just yet. But it really gets upsetting sometimes. For example, at my brother's wedding four years ago, the photographer thought I was his father. Really, I'm not kidding.

[2]And just a few weeks ago, I was a riding in a car with another one of my brothers when he stopped to pick up his paycheck. Anyway, his boss saw me in the car and asked him if _________________. Now, he only saw me from a distance, but it still hurt. Again, I'm not making this up.

[3]So I've decided to fight this battle in my own way. Since I obviously look old, I'm going to act young to compensate(弥补) for it. So what I am doing to act young? Well, it all has to with the way I move around.

[4]First, I try to walk faster than everyone else. That one is not a big deal for me, as I've always had a tendency to walk fast. It's a family trait（特性）.

[5]Second, I try to use quick movements. That means getting up from a sitting position quickly, sitting down quickly, lying down quickly, getting up from a lying position quickly, changing directions quickly, turning quickly, etc. Now this one presents a little more of a challenge to me. I have to be careful not to hurt or damage a sensitive body part.

[6]Of course, if all of that doesn’t work, there’s always the “Just for Men.”

The crisis(危机) at Japan’s Fukushima Dai-Ichi nuclear(核) energy center caused by the terrible earthquake has raised questions about the future of the nuclear energy industry. Arjun Makhijani is president of the Institute for Energy and Environmental Research in the United States. He says the disaster(灾难)in Japan is historic.
This week, the chairman of America’s nuclear agency said there is little chance that harmful radiation(辐射) from Japan could reach the United States. Gregory also said America has a strong program in place to deal with earthquake threats. No new nuclear power centers have been built in the United States since nineteen seventy-nine. That was when America’s worst nuclear accident happened at the Three Mile Island center in Pennsylvania. The accident began to turn public opinion against nuclear energy. At present, about twenty percent of electricity in the United States comes from nuclear energy.
German Chancellor Angela Merkel said Germany would close seven nuclear power centers while energy policy is reconsidered. The European Union is planning to test all centers in its twenty-seven member nations.
Developing nations are less willing to slow nuclear expansion. China said it will continue with plans to build about twenty-five new nuclear reactors（反应堆）. And India, under a cooperation agreement with the United States, plans to spend billions on new centers in the coming years.
Nuclear reactors supply fourteen percent of global electricity. Nuclear energy is a clean resource, producing no carbon gases. But radioactive waste is a serious unresolved issue. So is the presence of nuclear power centers in earthquake areas like the one near Bushehr, Iran.
