The Atlantic Ocean is one of the oceans that separate the Old World from the New. For centuries it kept the Americans from being discovered by the people of Europe.

It is more than 4,000 miles (6,400 km) wide where Columbus crossed it. Even at its narrowest it is about 2,000 miles (3,200 km) wide.   1.   .

Two things make the Atlantic Ocean rather unusual. For so large an ocean it has very few islands.   2.  .

One of the longest mountain ranges of the world rises from the floor of the Atlantic.   3.  . The tops of a few of the mountains reach up above the sea and make islands. The Azores are the tops of peaks in the mid-Atlantic mountain range.

Ocean currents are sometimes called “rivers in the sea”. One of these “rivers” in the Atlantic is called the Gulf Stream. It is a current（流） of warm water. Another is the Labrador Current --- cold water coming down from the Arctic.  4.  .

Today the Atlantic is a great highway. It is not, however, always a smooth and safe one. Storms sweep across it and pile up great waves. Icebergs float down from the far north across the paths of ships.

   5. . Columbus sailed for more than two months to cross it. A fast modern steamship can make the trip in less than four days. Airplanes fly from New York to London in only eight hours and from South America to Africa in four!

A We now have such fast ways of traveling that this big ocean seems to have grown smaller

B This narrowest place is between the bulge（鼓起） of South America and the bulge of Africa

C Also, it is the world’s saltiest ocean

D This big Atlantic Ocean is not easy and sometimes dangerous to cross

E This mountain range runs north and south down the middle of the ocean

F Ocean currents affect the climates of the land near which they flow

G The Atlantic furnishes much food for the people on its shores

Searching for the truth

Collecting mid writing news is like researching in history: the best information comes from those who were there at the time. So if' we want to study tile history of China in the sixth century AD, we look at the writings of the people who lived then. They are called the primary sources because they tell us what it was like to live then. People at a much later date who write about the same events are called the secondary sources.  For example, when we read the original writings of Jia Sixie on agriculture, we are reading a primary source; when we read about Jia Sixie in our textbook we are reading secondary source because the passage was written about him and his ideas many years after he died.

When we make news we use primary and secondary sources. We can see this most clearly in TV programmes. As we watch the news on TV, the person presenting the programme in the studio is the secondary source( because he tells us about the news) and the reporter in. Iraq or Washington is the primary source (because he is telling us about what is actually happening there). Without these reporters acting as primary sources, you would never find out what really happened in a war, earthquake, sports meeting, concert or festival. These reporters explain what is happening so we have a clearer idea of what is going on there. They often take photographers with them who act as primary source by giving pictures of events.

In a newspaper the position is different because these two roles are often combined. This means a reporter who investigates a story may be the same person who writes it. If this happens, the reporter is both the primary and the secondary source. But the photographer who works with him/her is still a primary, source.

One of the reasons that it is important to separate primary and secondary sources is that they help us to decide what is a fact and what is an opinion. A fact is something that everybody agrees has happened. An opinion is somebody's idea of what happened. So facts and opinions are often mixed in any report, whether in a newspaper or on TV.

What have you learnt from the above passage?

Primary Source	Primary sources are the writing of' the people who lived at (1)___________ time and offer an inside view of a particular event

The common cold is the world's most widespread illness, which is a serious infection that man receives.
The most widespread mistake of all is that colds are caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold by touching directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in separate Arctic (北极的)areas, explorers have reported being free from colds until touching again with infected people from the outside world by way of packages and mail dropped from airplanes.
During the First World War, soldiers who spent long periods in the trenches, cold and wet, seldom caught colds.
In the Second World War, prisoners at Auschwitz concentration camp, bare and starved, were astonished to find that they seldom had colds.
At the Common Cold Research Unit in England, volunteers took part in experiments in which they gave themselves to the discomforts of being cold and wet for a long time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in a room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.
If then, cold and wet have nothing to do with catching colds, why are they more frequent in winter? Despite the most hard research, no one has yet found out the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and that makes it easier for cold viruses to be passed on.
No one has yet found a cure for the cold. There are drugs and pain-killers such as aspirin, but all that they do is to reduce the symptoms.
【小题1】The writer thinks the cause of catching cold is due to_______.

A．touching anyone directly

B．touching anyone indirectly

C．cold weather

D．getting viruses from person to person

【小题2】Arctic explorers may catch colds when___.

【小题3】Volunteers taking part in the experiments in the Common Cold Research Unit___.

A．suffered a lot	B．never caught colds
C．often caught colds	D．became very strong

【小题4】The passage mainly discusses___.

A．the experiments on the common cold

Simply by analyzing a drop of blood, a doctor will be able to diagnose a birth defect or even cancer when it is in the early stage; using new technology, a material lighter but much stronger than steel can be produced.

These may sound like dreams at present. But the dreams may soon come true as research findings in laboratories are being turned into products more rapidly in the new century, according to experts participating in the fourth Asia-Pacific Economic Cooperation (APEC) Technomart, a technology exhibition and trade fair in Suzhou.　　

"Most people think nano-technology（纳米技术）is too far-fetched to be real. But in fact nano-technology has been applied in a wide range of fields, such as medicine. It is coming into our daily life," said Cheng Jiachong from a Hong Kong-based nano-technology firm.

Nano-technology based on the nanometer, the unit of which is a billionth of a meter, enables scientists to have new concepts of disease diagnosis and treatment on a molecular（分子）and atomic scale, Cheng said.　　

By using nanometer particles, a doctor can separate the fetus cells（胚胎细胞）from the blood of a pregnant woman to see if the development of the fetus is normal. This method is also being used in the early diagnosis of cancer and heart disease, he said.　　

One of the most significant impacts of nano-technology is at the bio-inorganic materials interface, according to Greg Tegart, executive advisor of the APEC Center for Technology Foresight.　　

"By combining enzymes（酶）and silicon chips we can produce biosensors. These could be implanted in humans or animals to monitor health and to deliver corrective doses（剂量）of drugs," he told the participants a technology forum during the exhibition.　　

"Nano-technology could affect the production of nearly every man-made object, from automobiles, tires and computer circuits（电路）, to advanced medicines and tissue replacement, and lead to the invention of objects yet to be imagined," said David Minns, a special advisor to the National Research Council of Canada.　　

It has been shown that carbon nano-tubes are ten times as strong as steel, with one sixth of the weight, and nano-scale systems have the potential to make supersonic transport cost- effective and to increase computer efficiency by millions of times, he said.

The experts agreed that the APEC technology exhibition and trade fair provided many chances for exchanges of innovative ideas and products.
