31^st October —— A team of British explorers has announced they are going to the North Pole to measure the ice cap’s thickness. The exploration will take ground-based readings (仪表的读数) of an ice formation which most scientists agree is shrinking at an alarming rate.

    Explorer Pen Hadow’s three-member team will pull a sled-fixed radar device, which measures ice density every eight centimeters, 2,000 kilometers across the Arctic and will produce millions of readings.

    They will leave in February, 2008 and will face temperatures of -50℃ on a journey that will take up to 120 days. They have been testing their equipment in Britain and Canada.

    Hadow is excited about the prospects (前景), “For the first time we will be able to transmit video images — webcam film of the expedition — as it unfolds so people can track us, and the whole idea is to engage as many people as we can in what we’re doing.”

    New fallen snow on top of the ice makes ground-based measurements more accurate than satellite data.

    “It has been in the planning stage for a while,” said Hadow. “We spent the last two years developing impulse radar (冲击雷达), which normally is about 100 kilograms and hangs under an aircraft and so on. We’ve managed to get it down to about 4 kilograms. It’s the size of a briefcase and we are dragging it behind the sled as we go.”

　　　　The ice cap shrank enough in 2007 so that a pathway through the cap known as the Northwest Passage opened up during the melting of the Arctic summer.

    Cambridge University’s Joao Rodrigues explains, “Thickness of the ice cap will determine how much solar radiation will be reflected and the heat exchange between the ocean and the atmosphere and it is thus a vital component (成分) of climate models.”

    If warming trends continue, some experts predict that the Arctic Ocean could be ice-free during the summer within a few decades.

The united States has about 475,000 school buses — all painted yellow. Each day they carry more than 25,000,000 children, half of all schoolchildren in the country. But these buses, on average, use four liters of diesel (柴油) fuel to travel less than sixteen kilometers. When the school year began last fall, diesel averaged 55 cents a liter nationally. The price nearly doubled, to a dollar and 8 cents, by the end of school in June.

Bob Riley speaks for the American School Bus Council. He says fuel prices for schools are not much lower than others have to pay. As a result, schools are looking for ways to reduce transportation costs. Bus routes are being redrawn or, in some cases, canceled. Some areas are buying buses that use natural gas or other alternative fuels. Other steps include fewer field trips and less travel by sports teams. And some school districts may end any bus service not required by law.

Studies show that school buses are the safest form of transportation to and from school. The American School Bus Council says cuts in bus service are bad for children and possibly the environment. It says removing buses from the road will mean an increase in other vehicles transporting students. Spokesman Bob Riley says another concern is that reducing bus services might reduce attendance.

But it could also get more children to walk or bicycle to school. And that would surely make people happy at the National Center for Safe Routes to School. More kids walking or biking safely to school is the aim of a three-year-old federal program, part of an international movement. The goal is to increase physical activity and reduce air pollution. The United States will celebrate Walk to School Day on October eighth this year. But for some students, high fuel prices could make every day a walk-to-school day.

1.What does this passage mainly tell us?

2.In order to cut down transportation cost, many schools take the following measures EXCEPT_____.

3.The National Center for Safe Routes to School encourages more children to walk or bike to school in order to ____.

What kind of job do you want to do in the future ? One that earns the most money or one that gives you the highest social position? What about a job that makes you feel happy? Surprisingly, these three things do not always go together in the job world .

According to a general social survey by the National Organization for Research at the University of Chicago in the US, the ten happiest jobs are not those with better pay or higher social position. They are ordinary jobs.

But what is it that makes a “happy” job?

Researchers found that people are happier when they feel they are doing something worthwhile. Six of the top ten happiest jobs are based heavily on helping others, such as firefighters, teachers, and physical therapists(理疗师 ).

Being able to express oneself is also important for people to feel satisfied . Take authors as an example. Their pay is “ridiculously low or non-existent”, but “the freedom of writing down the contents of your own mind leads to happiness ,”wrote business author Steve Denning on his blog on Forbes.com.

These jobs are greatly different to the top ten “hated jobs”, according a website survey earlier this year. Director of information technology, sales manager, technical specialist and others that are generally considered respectable jobs are on the list.

Todd May from The New York Times didn’t find the results strange. He argued that

“ a meaningful life must, in some sense then , make people feel worthwhile”. If a person doesn’t participate in the causes “ that are generally regarded as worthy, like feeding and clothing the poor, their life will lack meaning ,”he said . Work takes up the greater part of most people’s  lives . It’s no wonder that the people with the most worthwhile jobs are the happiest of all.

However, it’s important to remember that these two surveys are broad ones and that it doesn’t matter whether your dream job is on the two lists. Now it is the time to think about the future . After all, something that satisfies your mind will always bring you happiness.

1.According to the passage , which of the following is probably a happy job?

2.Steve Denning thinks that being an author is happy mainly because authors_____.

3.From the passage we learn that_________.

4.In the last paragraph the author stresses that_________.
