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 British coloney(殖民地)of Bermude is a top summertime escape. Yet, even through October, Bermuda isn't ready to stop for the winter. During this month, world-class festivals on teh island keep things lively and the weather remains comfortable enough for Bermuda shorts and bathing suits.
In October, Bermuda hosts two major festivals—the Bermuda Music Festival and the Bermuda Culinary Arts(厨艺) Festival. The 10th anniversary Bermuda Music Festival begins October 5 and features three days of performances at the Royal Naval Dockyard(皇家海军造船厂)on Bermuda's West End. Featured main stage performers include Joss Stone, Pattie Labelle, and Al Green, and a second stage spotlights local Bermudian artists. General admission tickets start at $60 for on e day or $160 for a three-day pass.
Starting October 21, the Culinary Arts Festival brings some of North America's top chefs to the island for four days of food and wine tastings, conferences and cooking competitions. Participating chefs include Todd English and Michael Lomonaco, among others. Three-day festival passes start at $649 per person, but you can also buy separate tickets for individual events.
Even if you don't attend one of the festivals, there's still plenty to do. With mostly sunny days and temperatures averaging aroung 79 degrees, the weather is just right for participating in Bermuda's two favorite pastimes—golf and tennis. With fewer visitors on the island than during the summer, you may have an easier time getting the best times or a spot on the courts. It's also still warm enough to enjoy the island's pink sand beaches and go swimming, because the water keeps the summer's heat longer than the air. Of course, you can always shop in the city of Hamilton's upscale(质优价高的) small goods arts and crafts shops.
1.The Culinary Arts Festival lasts _____.
A. from October 5 to 7 B. from October 5 to 8
C. from October 21 to 24 D. from October 21 to 25
2.The best time to travel to Bermuda is ______
A. spring B. Summer C. Autumn D. winter
3.This text is most probably a(n) ______
A. advertisement B. introduction
C. report D. instruction
4.According to the text which of the following statements is true?
A. In winter travelers can't swim in the sea.
B. Bermuda is an island controlled by the UK.
C. The two festivals fall on the same period of October.
D. Bermuda's two major festivals in October are mainly for the British.

Oumuamua,an object through space that was discovered on October 19th, has already made history.The speed at which it is moving relative to the sun means that it cannot be native to the solar system. Its official name is thus II/2017 UI, with the “I” standing for “interstellar(星际)”—the first time this name has ever been used.
That is exciting.Some scientists, though, entertain an even more exciting possibility: what if Oumuamua is not an asteroid(小行星),as most think, but an alien(外星的)spacecraft? Asteroids come in ll sorts of shapes and sizes, but Oumuamua seems particularly different.As best as astronomers can tell, it is cigarlike,being roughly 180 meters long but only about 30 meters wide.That makes it longer than anything known of in the solar system.Such a shape would be a sensible choice for a spaceship,since it would minimize the scouring(冲刷)effect of interstellar dust.
With that in mind the Breakthrough Listen project, an organization aimed at hunting for alien life, plans to turn the world’s biggest radio telescope,the Green Bank instrument in Virginia,towards Oumuamua to see if it can hear anything interesting.Oumuamua is currently about twice as far from Earth as Earth is from the sun. At that range,the telescope should be sensitive enough to pick up a transmitter about as powerful as a mobile phone after just a few seconds—worthy of observations.
Will it find anything? Almost certainly not.Oumuamua has the same reddish color as many as asteroids,so probably has a similar composition.And, if it really is a spaceship, it is strange that signs of its artificial origin have not been seen already.It could, in theory, be a derelict(遗弃星球). But in that case the telescope is unlikely to hear anything. By far the most likely option is that it is exactly what it seems to be: a huge space rock, one that has come to the solar system from the vast space between the stars.
1.What makes some scientists think Oumuamua is possibly an alien spacecraft?
A. Its size. B. Its color.
C. Its shape. D. Its speed.
2.What does the underlined word“that”in the third paragraph probably mean?
A. The research into the solar system.
B. The purpose of hunting for alien life.
C. The effect of interstellar dust on Oumuamua.
D. The possibility of Oumuamua being a spaceship.
3.What is Oumuamua most likely to be according to the author?
A. An asteroid. B. A space rock.
C. Interstellar dust. D. An alien spacecraft.
4.It can be inferred from the last paragraph that__________.
A. Oumuamua will return to where it’s from soon
B. Oumuamua’s real identity remains to be found out
C. astronomers have not seen signs of Oumuamua’s artificial origin
D. the Green Bank telescope has already heard something from Oumuamua
