A new argument has been put forward as to whether penguins are disturbed by the presence of tourists in Antarctica.
Previous research by scientists from Keil University in Germany monitored Adelie penguins and noted that the birds’ heart rates increased dramatically at the sight of a human as far as 30 meters away. But new research using an artificial egg, which is equipped to measure heart rates, disputes this. Scientists from the Scott Polar Research Institute at Cambridge say that a slow moving human who does not approach the nest too closely, is not viewed as a threat by penguins.
The earlier findings have been used to partly explain the 20 per cent drop in populations of certain types of penguins near tourist sites. However, tour operators have continued to insist that their activities do not adversely affect wildlife in Antarctica, saying they encourage non-disruptive behavior in tourists, and that the decline in penguin numbers is caused by other factors.
Amanda Nimon of the Scott Polar Research Institute spent three southern hemisphere summers at Cuverville Island in Antarctica studying penguin behavior towards humans. “A nesting penguin will react very differently to a person rapidly and closely approaching the nest,” says Nimon. “First they exhibit large and prolonged heart rate changes and then they often flee the nest leaving it open for predators (掠夺者) to fly in and remove eggs or chicks.” The artificial egg, specially for the project, monitored both the parent who had been ‘disturbed’ when the egg was placed in the nest and the other parent as they both took it in turns to guard the nest.
However, Boris Culik, who monitored the Adelie penguins, believes that Nimon’s findings do not invalidate his own research. He points out that species behave differently – and Nimon’s work was with Gentoo penguins. Nimon and her colleagues believe that Culik’s research was methodologically flawed because the monitoring of penguins’ responses needed capturing and restraining the birds and fitting them with beart-rate transmitters. Therefore, argues Nimon, it would not be surprising if they became stressed on seeing a human subsequently.
小题1:According to the passage, what overall message is presented?
A.No firm conclusions are drawn. |
B.Neither Culik’s nor Nimon’s findings are of much value. |
C.Penguin reduction is closed related to tourist behavior. |
D.Tourists are not responsible for the fall in penguin numbers. |
A.Penguins are harder to research when they have young. |
B.Tour operators should encourage tourists to avoid Antarctica. |
C.Not all penguins behave in the same way. |
D.Penguins need better protection from tourists. |
A.They are groundless. |
B.They are factual. |
C.They are descriptive. |
D.They are conflicting. |
A.later on |
B.carmly |
C.separately |
D.in the same place |
答案
小题1:A
小题2:C
小题3:D
小题4:A
解析
小题1:推理判断题,文章并没有给予明确结论。
小题2:推理判断题,根据第四段A nesting penguin will react very differently to a person rapidly and closely approaching the nest可知,不同的企鹅反应不一样。
小题3:根据最后一段的however可知,文章观点相互矛盾,冲突。
小题4:猜测词义题。根据内容可知,企鹅先被人类抓住,所以后来再看到人类就不感到惊讶了。

Many businesses today use conferences as a means of discussing new plans of the company. As people are paying more attention to the environment and green problems, more businesses are looking for ways to reduce their negative effect on the environment. Many businesses do this by using Web conferencing.
Web conferencing is a technology that allows people to communicate more effectively over the Internet. It’s an easy way of hosting and attending conferences without having to leave the office. Each of the people involved in a Web conference will be posted an invitation to the conference with the time and date of the Web conference on it. When the conference is ready to begin, all participants (参与者) must sit at their computers and they will be connected over the Internet.
With Web conferencing all participants attend conference from the comfort of their own desks. Obviously, in doing this no fuel is used in traveling to and from a conference, and less work is taken up in attending a conference.
Any material to be used during Web conference is simply e-mailed to all the participants before the conference. Participants can then either choose to print material or read it on screen. This not only saves paper but also greatly reduces mailing costs for the business.
As a conference hall or business center isn’t being used, it means that the only power that is used is the power that is used by the participants’ personal computers. Similarly, conference organizers don’t have to arrange for food or overnight accommodation. All this means that less energy is used.
Often in business some companies actively choose to do business with other companies that do many things to reduce their negative impact on the environment. And Web conferencing helps you show other businesses that you are willing to work hard for the green cause.

Every day, about one-quarter of American adults eat at fast-food restaurants. Cheap, tasty, and convenient, fast food is rich in fat and calories, and it’s low in fiber and nutrients. Thanks in large part to fast food, half of America’s adults and one-quarter of its children are fat, double the rate of a generation ago. In the past two decades, eating habits have changed as people pay more attention to their health. However, many Americans continue to eat red meat (beef in particular) as well as pork, chicken and other foods. Although beer and wine are popular in most areas, many Americans abstain from alcohol, because they think they will become healthier without drinking it. Various kinds of mineral water are commonly available.
Eating styles and habits vary between people of different backgrounds, but Americans generally eat with the fork in the hand with which they write. A knife is used for cutting and spreading; otherwise, it is laid on the plate or table. Fast foods, such as chips, fried chicken, hamburgers, and pizza, tend to be eaten with the fingers. There is an obvious difference between what people may do at home or in a fast-food restaurant, and how they act in a more formal restaurant. Because both parents often work outside the home, some Americans are less likely to sit down as a family to eat once the children are older and able to prepare their own food or serve themselves.
小题1:How many adults became fat after eating fast foods a generation ago?
A.12.5% of them | B.25% of them |
C.50% of them | D.75% of them |
A.they want to keep healthy |
B.economy develops faster |
C.they have different backgrounds |
D.they have to work outside |

People celebrate birthdays in almost every country on earth. And they celebrate them in many different ways.
In China and in Japan, for example, the arrival of New Year is more important than a person’s birthday. So everyone adds a year to celebrate their ages on New Year’s Day, instead of on their birthdays,
In Brazil, the special birthday food isn’t cake, but special candles. In China, it’s long noodles—for long life. In Iceland, people have pancakes with candies rolled inside them on birthdays.
In Britain, a birthday is an all-day celebration. At school, the birthday child is lifted up and “bumped” by his classmates. This means the child is lifted by the feet and arms and bumped to the ground, once for each year once for good growth. In Israel, the same custom is followed, except the birthday person is lifted and lowered while sitting in a chair.
In Holland, children not only get presents, but also give things out. They give cakes, cookies and candles to their classmates and teachers on their birthdays.
In Mexico, it’s good luck to give birthday greetings as early in the day as possible. So it’s usual for the birthday child to be woken up at midnight by fiends singing birthday songs.
In India, birthday celebrations also begin before dawn. Prayers and blessings must be said before morning comes.
In Thailand, two tall candles are lighted the night before the birthday. One is as tall as the birthday person. If it goes out early, it’s bad luck. Another customs of Thailand is that they buy live fish and birds for the birthday person and then the birthday person frees the animals, and it brings good luck.
In Nigeria, people in a certain age group celebrate their birthdays together, on a certain day.
In many countries birthday customs are changing. Old customs are giving way to western style of birthdays, with candle topped cakes. But one thing never changes—birthdays are special days for everyone!

Machu Picchu is considered to be a truly extraordinary archaeological(考古学的) discovery and is one of South America’s largest tourist sites. As many as one thousand visitors visit the ancient Incan(印加文化的) ruins daily. What draws vacationers and adventurers to this remote location high in the Andes Mountains of Peru(秘鲁)? A large part of the attraction is the mysteries that surround Machu Picchu. For example, Machu Picchu is considered “the lost city” of the Incas because it was never found by Spanish invaders and was known to only a few local peasants for almost four hundred years.
The “city in the clouds”, Machu Picchu’s lasting beauty comes from the careful blending of its striking architecture with its mountaintop environment. Its greatest skill shows are in the stone structures, which equals that of the ancient Egyptians. The stone blocks were so appropriately cut that they fit together without the need for mud. The largest stones at Machu Picchu weigh as much as fifteen tons! It has been difficult to explain how the huge blocks were transported. The buildings, including many that have survived lots of earthquakes, contain stones which interlock so perfectly that a knife cannot be forced between them. When compared to other ancient civilizations, it is difficult to understand how Machu Picchu could have been missed by the Spanish and lost from history for four hundred years.
For many of the mysteries of Machu Picchu being unsolved, it is clear why Machu Picchu remains “the most famous ruins in all of South America”.
小题1:Which of the followings is NOT a mystery of Machu Picchu?
A.Machu Picchu is called the “city in the clouds”. |
B.Machu Picchu remains “the most famous ruins of South America”. |
C.Machu Picchu is “the lost city” of the Incas. |

B.all of the mysteries of Machu Picchu have been solved |
C.the city has never been discovered by people outside |
D.Machu Picchu is the most valuable ruins in history. |
A.ask us to pay a visit to Machu Picchu |
B.show us the beauty of Machu Picchu |
C.introduce Machu Picchu’s mysteries |
