As the world’s least-known place, Antarctica is of great interest to scientists around the world. In 1983, China joined the Antarctic Treaty (《南极条约》). The treaty made Antarctica a peaceful place for member countries to do scientific research. During 30 years, China has sent many scientists to Antarctica. They mostly look at the resources under the icy land and do research about climate change and marine (海洋的) biology.
Antarctica is a place with fantastic views. However, life there is very hard. Food is one of the biggest problems. Frozen (速冻) food which can be heated easily is people’s daily food. Fresh vegetables are hard to grow in the cold weather. Therefore, scientists often eat dried or canned vegetables.
Sleep is also troublesome. In Antarctica, summer lasts from November to March. During this period, Antarctica points to the sun and receives sunlight 24 hours a day. In order to get some sleep, scientists cover the windows with black plastic cloth to create “night”.
Working in Antarctica is dangerous, especially when meeting gale-force (七级以上的) winds. Sometimes the wind is even stronger than a typhoon. It can easily blow people away. So there are ropes that connect buildings of some research stations. People can hold these ropes to keep their balance in forceful winds.
What’s more, communicating with others is difficult. Without cables and Internet in some research stations, two-way radios are the only tools to communicate. If people want to say hello to friends and relatives, they can use satellite phones.
Although it is challenging to work in Antarctica, scientists’ passion to learn about this mysterious land will never end. It is hopeful that one day they will step every corner of this icy land.

To use your dictionary correctly, you need to understand how the dictionary works. At the front of the book, you will find some exercises to help you make the most use of your dictionary.
If you look up the word “colour”, you will find two spellings for this word. “Colour” is used in British English, while “color” is used in American English. When such a thing happens, the dictionary shows it with the word “BrE” for British English and “AmE” for American English.
The dictionary also helps you pronounce words correctly. It uses a special alphabet (特殊字母表) to show pronunciation. If you turn to the inside back face, you will see all the phonetic letters (音标) with some words to show you how they are pronounced. Just have a look at this page when you’re not sure how to say a word.
The most important reason for using a dictionary is to find out the meaning of a word—its DEFINITION.
In this dictionary, the definitions have been written using only 2000 words. This means that the definitions of even the most difficult words are simply explained and easy to understand.
小题1:According to the passage, “neighbor” is used in ______ English.
A.Australian | B.Canadian | C.American | D.British |
A.词性 | B.词条 | C.词库 | D.词义 |
A.some of the difficult words | B.all the words in a simple way |
C.all the easy words | D.the words of two meanings |
Fathers who value (重视) education have children who do better in school than those children whose fathers don’t value education. What’s more, fathers who spend quality time with their children may give their children happy memories which may last a lifetime.
While each father is a unique person who educates children in his own style, good fathers have something in common.
Good fathers attend their children’s school activities. They also involve the children in their lives and the adult world by taking them to see the workplace, or by taking them when the car needs to be repaired, etc.
Good fathers expect a great deal from their children, but also accept and support the unique individuals (个体) that their children are becoming.
Good fathers prefer explanations and reasoning to force.
Good fathers know their time with children is really an investment (投资) in them.
Being an involved father is good for children and good for fathers. Both children and fathers have the chance for growth and development. Today’s lifestyles are changing. More and more fathers are keeping a balance between their personal life, work, and family time.
小题1:According to the passage, we can find that .
A.fathers have an important influence on their children from babyhood through adulthood |
B.fathers’ involvement (介入) is the most important in children’s development |
C.all fathers have the same way of educating their children |
D.fathers are more important than mothers in the family |
A.has the same ideas as others |
B.is the only one of his type |
C.does everything without considering others’ ideas |
D.tries to do everything well |

C.Good fathers try to make it clear to their children that staying with their fathers is an investment. |
D.Good fathers improve themselves when they spend time with their children. |
A.how to be a qualified father |
B.the growth and development of both fathers and children |
C.the father’s role in the growth and development of children |
D.the change of the father’s role in modern society |
Recently, two scientists, Jose Millan and Michele Tavella from the Federal Polytehnic School in Lausanne, Switzerland, show a small robotic wheelchair directed by a person’s thoughts.
In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.
“Our brain has billions of body cells(细胞). These send signals through the spinal cord(脊髓) to the body part to give us the ability to move. But spinal cord injuries(脊柱受伤) or other conditions can prevent these weak electrical signals from reaching the body part.” Tavella says. “Our system allows disabled people to communicate with outer world and also to control machines.”
The scientists designed a special cap for the user. This head cover picks up the signals from the scalp(头皮) and sends them to a computer. The computer finds meanings of the signals and commands the wheelchair with an engine. The wheelchair also has two cameras that tell objects in its path. They help the computer react to commands from the brain.
Prof. Millan , the team leader, says scientists keep improving the computer software that finds meanings of brain signals and turns them into simple commands.” The practical possibilities that BCI technology offers to disabled people can be grouped in two kinds: communication, and controlling objects. One example is this wheelchair.”
He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can get advantages from. And the other is sure that they can use the technology for long.
小题1:BCI is a technology that can________.
A.help to make computer systems more modern |
B.connect the human brain with computers |
C.help the disabled to be healthier |
D.control a person’s thoughts |
A.scalp→computer→cap→wheelchair |
B.computer→cap→scalp→wheelchair |
C.scalp→cap→computer→wheelchair |
D.cap→computer→scalp→wheelchair |
A.make money from them |
B.prove the technology useful to them |
C.make them live longer |
D.learn about their physical condition |
A.Switzerland, the BCI research Center |
B.New Findings About How the Human Brain Works |
C.BCI Could Mean More Freedom for the Disabled |
D.Robotic Vehicles Could Help to Cure Brain Sickness |
"When we say some people "sweet", we mean they are kind and friendly to us. Perhaps this word can help us learn more about people"s feelings and acts." said Brian Meier, a scientist from the study team. "Taste is something we experience every day. What we have done is to find whether we can know someone"s character and behavior depending on their taste."
In one of their experiments, college students were asked questions about their character- whether, for example, they were soft-hearted or not. Then they were asked to make a list of their favorite food. According to their answers, the scientists found that the students who liked sweet food were nicer.
In their another experiment, the scientists found that people who preferred sweet food such as cookies and chocolate were more willing to help other people in need, and those who ate non-sweet food such as chips weren"t. For example, people with a sweet tooth were more likely to volunteer to clean up their city, visit sick children in the hospital and so on.
The result of the experiments is that people"s helpfulness or being nice has something to do with their taste for sweet food. So eating sweet food is a useful way to make people nice and helpful. Next time, try some ice-cream.
小题1:The underlined word "it" in the sentence "Many experts use it to tell people it"s important to have a good eating habit." refers to______.
A.the sweet food | B.the English saying |
C.the American team | D.the eating habit |
A.overweight | B.excited | C.relaxed | D.friendly |
A.chips | B.chocolate | C.ice-cream | D.cookies |
A.scientists asked college students questions about their future |
B.scientists told college students not to eat sweet food |
C.people with a sweet tooth are more willing to help others |
D.people"s character has nothing to do with their taste |
