31st 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.

BERLIN (Reuters)—Germany’s postal service has announced plans to explore improved service and help protect the environment by getting “fetch friends”—ordinary people traveling across cities—to deliver parcels on their way.
It is hoped that the move, which will be tested in the coming months, might lessen traffic in inner cities and reduce CO2 emissions(排放). This should help DHL, a division of the German postal service, reach its target of improving the company’s carbon efficiency by 30 percent before 2020.
“As the world’s biggest logistics(物流) provider, we recognize a special responsibility to reduce the impact on the environment as much as possible,” said Frank Appel, Chief Executive Officer of Deutsche Post DHL, in a statement referring to a variety of measures being considered.
The “fetch friends” find out online about parcels that need delivering to people who live or work along the way that they are planning to travel through the city. They then select the ones that they want to take.
Codes(编码) sent to their mobile phones tell the volunteers where to pick the packages up. Parcels can be taken part of the way or passed on to another volunteer but all volunteers need to have the right code on their mobile phone so the track and trace system can be updated.
Logistics companies will be responsible for looking after the operation to make sure that the privacy of post is respected.
It’s hoped that this could be done using mobile phones but DHL says it recognizes that some security issues remain to be worked out.
1.According to the passage, the “fetch friend” program ________.
A. has been tested for months
B. aims to reduce the cost of the service
C. employs environmentalists to help with deliveries
D. encourages ordinary people to help cut the carbon footprint
2.Which of the following statements is TRUE of DHL?
A. It belongs to the Germany’s postal service.
B. It has the most up-to-date tracking system in Germany.
C. It has succeeded in improving its carbon efficiency by 30%.
D. It has designed many measures to improve its service speed.
3.What may be a problem with the new service according to the article?
A. Volunteers’ not allowing to select parcels.
B. The wrong codes in the mobile phones.
C. The possibility that parcels could be opened on the way.
D. Parcels’ being taken to the destination by a single volunteer.
4.What might be the best Title for the best passage?
A. New Challenges for the Postal Service
B. A Greener Way to Deliver Parcels
C. Solutions for Global Warming
D. Statements from DHL

The royal family is a part of British history and cultural identity.
Up until the 17th century, people believed that the British king or queen had a “divine(天赐的)right” to rule. This was the idea that God chose the king or queen and that he or she was therefore above the law. However, this idea was challenged during the English Civil War, when King Charles the First was put in prison and then killed in 1649.
So what role does the British royal family have today?
The Queen is head of the UK and the Commonwealth. She has important formal duties that go with her different titles. As Head of State, for example, she represents the UK on visits abroad and invites other world leaders to visit the UK;as Head of the Armed Forces in name, only she can declare when the UK is at war or when a war is over. She has to sign many government and Commonwealth documents every day.
Although the royal family does the work for the UK, there are British people called“anti-monarchists(反君主制者)”who do not believe there should be a royal family. One criticism(批评意见)is that the British people should not have to pay for the royal family with their taxes(税).
Today, the royal family works hard to be relevant(相关的)in the modern world. The Queen still gives a speech to the nation on television at Christmas, but it gets less and less formal every year;now it is even available as a podcast(播客).
In 2005, after graduating from university, Prince William spent time teaching English in Uruguay, the sort of work many ordinary young British people do in their gap years.
1.What can be concluded from the first two paragraphs?
A.The British king or queen is considered above the law.
B.The English Revolution put an end to the British royal family in 1649.
C.The British king or queen is no longer believed to rule by divine right.
D.The royal family didn’t play an important role in Britain in the 17 th century.
2.Which of the following is among the formal duties of the Queen?
A.Traveling around the UK.
B.Declaring when the world is at war.
C.Inviting other leaders to have dinner with her.
D.Signing Commonwealth documents every day.
3.With the example of Prince William in the last paragraph, the author intends to show that________.
A.Prince William is very popular in the UK
B.the royal family is trying to connect better with ordinary people
C.Prince William has made an effort to win young people’s admiration
D.many young British people do voluntary work
4.It can be inferred from the passage that ___________.
A.the royal family doesn’t have to pay taxes
B.the British people are all in favor of the royal family
C.the British people can talk to the Queen through a podcast
D.the royal family attacks republicans through media and press
