Fever has usually been regarded as a threat to health. However, no one has actually proved that fever is dangerous. This fact attracted the attention of Matthew J. Kluger. Imagining that fever might not be as harmful as it had been supposed, Kluger set up a series of experiments with lizards (蜥蜴).
What Kluger and his team did in their first experiment was simple. They put some lizards in a sand-box, one end of which was heated to 44°C, while the other was at a room temperature. It was found that the lizards moved from one part of the box to the other in order to keep a constant temperature of about 38°C. Having shown that normal lizards regulate (调节) their own temperature, Kluger, in a second experiment, then set out to show that lizards, like most other animals, develop fever when infected (感染). This was done by making lizards infected with bacteria (细菌) that were known to cause disease. As the team expected, the infected lizards remained longer in the heated part of the box, until they had raised their body temperatures to two or three degrees above normal. In other words, the sick lizards gave themselves fever.
In a third experiment, the team observed the effect of temperature on the survival of the lizards. One group of infected lizards was given a fever-suppressing (退烧) drug. The other group was given no drug and ran a fever, that is to say, they kept a higher temperature for four or five days before seeking a cooler environment. The results were impressive. Of those which raised their body temperature, all but one remained alive. Of those given the fever-suppressing drug, more than half died. Similar results have since been produced in other animals. For example, infected fish swim to warmer water, and will die if not allowed to do so.
An important conclusion can be drawn from these experiments. As Kluger points out, lizards have been on earth for hundreds of millions of years. It is reasonable to suppose that a response that is so old has been kept by nature for some purpose. It would appear, therefore, that fever does not make disease worse. Rather it is part of the mechanism (机能) by which infection is controlled.

The African grey parrot’s ability to talk and mimic sounds makes it a charming companion. African grey owners often report that their greys oftentimes talk in context and can understand their people’s emotions (情感). The African grey parrot is not just a top talker - this bird is also known for its extreme intelligence, which gives them the name “The Einsteins of the Bird World”.
The bird is medium-sized, dusty-looking and almost pigeon-like. It has a bright red tail, intelligent orange eyes, and a stunning scalloped (扇形的) pattern to its feathers. Their diet in the wild consists mostly of nuts, seeds, fruits, and leafy matter.
At home, African greys need plenty of toys that challenge their intelligence, such as food searching and puzzle toys. Nutri-Berries by Lafeber Company are a perfect choice, which, with a balance of grains, seeds and other nutrients in the shape of a berry, encourages African greys to hold, bite off, and even play with, just as they do in the wild.
African greys seem especially affected by stress and disturbing noise in their environment and can be put more at ease by placing one corner of the cage against a wall as opposed to in the middle of a room.
African grey parrots are more likely to suffer from lack of Vitamin-A/beta-carotene, and therefore benefit from eating vegetables high in beta-carotene, such as cooked sweet potato and fresh kale. Lack of Vitamin-D is another concern, especially for greys on a poor diet. Offering a balanced, pill-shaped diet, such as Nutri-Berries, helps prevent vitamin and mineral shortage.
1.Why are African grey parrots called “The Einsteins of the Bird World”?
A.Because of their brain size. B.On account of their intelligence.
C.Owing to their rich emotions. D.Due to their talking ability.
2.What can “Nutri-Berries” probably be?
A.A brand of bird food. B.Puzzle toys for birds.
C.A type of round fruit. D.Wild Intelligence games.
3.What is the characteristic of African grey parrots?
A.They may get ill due to lack of Vitamin
B.They prefer to stay in the middle of the room.
C.They are dusty looking with blue eyes.
D.They are smart and love to have fun.
4.Where can we most probably find the passage?
A.In a wildlife magazine. B.In science fiction.
C.In a travel guide. D.On a shopping website.
Suppose you are about to complete high school and are thinking about attending a college or university. After doing some research, you find a school you would like to attend, but have questions about the application process. So you go to the school’s website in the hope of finding a few answers.
Time goes by and you, a student, still do not have the answers. You almost feel like giving up. But today, as you can see, artificial intelligence is so advanced. You find a message appears on your computer or personal electronic device. It says something like: ''How can I help? '' Writing back to the website, you try to explain your problem. You possibly get a few questions to clarify what your concerns are. Then, almost immediately, the person with whom you are in contact provides the information you are seeking.
In fact, you are not actually communicating with a school official. You are not even dealing with a human being. You are in contact with a computer program, or chatbot. It is using artificial intelligence, AI for short, to understand and communicate with you. This might sound strange. But chances are that this would not be the first time you have communicated with a computer program without knowing it. In recent years, chatbots have become a common tool for banks and large companies around the world.
Having human beings available to answer people’s questions and complaints can be costly, requiring many workers. And in most cases, employees can only work for several hours in a day, increasing customers’ waiting time for a response, but the chatbot can work around the clock. So not only companies, but a growing number of universities have also begun using the chatbot technology.
Australia's University of Adelaide noted a major improvement in its service to student after employing a chathot to deal with application questions in 2018. It said that students received responses 13 times faster, and students’ approval of the quality of service increased by 60 percent. And just the speed of reacting to questions is the chatbot's major strength.
1.How does the author introduce the topic of the text?
A.By assumption. B.By comparison.

A.To tell time and tide wait for no man.
B.To advise students should clarify their questions.
C.To present the communication convenience brought by Al.
D.To show the phenomenon that students are addicted to computers.
3.What is the main advantage of the chatbot technology?
A.Its low cost. B.Its ease of use.
C.Its short working hours. D.Its quick response.
4.What is the main idea of the text?
A.Artificial intelligence is developing rapidly.
B.Robots are gradually replacing human services.
C.Employees chat with robots without knowing them.
D.More universities use chatbots to communicate online.

What will the home of the future look like? A team of architects in Hong Kong say that city homes will be tiny, as populations continue to grow and space becomes more expensive.
They have designed “space flats” with just 30 square meters in size as the houses in the following years. These flats have several small rooms: a living room, a bathroom and a bedroom, but everything is carefully planned to make good use of the limited space.
The living room is the main room of the flat. It can be used as an office, a kitchen or even a second bedroom. There is a sofa that can be changed into a bed. The dining table can be changed into a computer desk. And, if not needed, both the sofa-bed and the table can be folded and put away. There is a flat-screen TV, which can also serve as a computer monitor. In one corner of the room, a small cooker, a microwave oven and a mini-refrigerator are hidden out of sight. The other rooms are small but practical. The bathroom contains a toilet and a shower. The double bed in the bedroom can also be transformed into a sofa, if required.
“Space flats” are wonderful and they are now being tested in a building in Hong Kong. It is believed that “space flats” will be improved to be our future homes.
