【题目】There is an English saying that "Laughter is the best medicine. "Until recently, few people took the saying seriously. Now however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter can really improve people's health.

Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their hearts, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, makes the heart beat quicker and makes people breathe deeper; it also works on several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.

Other tests have shown that laughter appears to be able to reduce the effects of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated (, 忍耐) the pain for the longest time was the group which listened to a funny program. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain which diminishes both stress and pain.

As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they help to improve their patients' condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.

【题目】The current Ebola (埃博拉病毒)outbreak in western and central Africa has infected at least 3,069 people, including 1,552 dead, making it the largest outbreak in history. Ebola is a deadly virus-about 60 percent of people infected with it have died.

How is Ebola doing its harm?

When a person becomes infected with Ebola, the virus damages the body’s immune (免疫的)cells, which defend against infection, said a researcher at Lancaster University. But if a person’s immune system can stand up to this attack, then he is more likely to survive the disease.

The patients that survive it best are those who don’t get such a bad disadvantage in immune system. But if the body isn’t able to get rid of this attack, then the immune system becomes less able to regulate(调节) itself. This means the immune system is more likely to run out of control, leading to a drop in blood pressure, multi-organ failure and eventually death.

What are the common symptoms of the disease?

Fever. Headache. Joint and muscle aches. Weakness. Diarrhea. Vomiting. Stomach pain. Lack of appetite. Chills. Rash. Redness in the eyes. Hiccups. Cough. Sore throat. Chest pain. Difficult breathing or swallowing. Bleeding inside and outside of the body.

How to prevent the spread of Ebola?

Ebola can be spread primarily via direct contact with patients, specifically the blood and fluids of an infected patient.

We should avoid contact with infected patients and objects such as clothing, bedding, and needles used by them. Avoid areas where infections have been reported. For now, the disease has only been confirmed in central and West Africa, four cases in America and Europe. Avoid eating wild-caught bush meat. Researchers have suspected that the disease came to humans via animals, probably through the meat of primates(灵长类). If you’re in an area where the disease has been reported, avoid purchasing, eating, or handling wild game to stay on the safe side.

Wear protective medical clothing if you’re around infected patients. Extreme caution is necessary. Hospital workers must use masks, gloves, goggles, and gowns, which needed to be worn at all times if you’re around infected patients.

How Do People Survive Ebola?

Doctors don’t know for certain who will survive Ebola, and there is no specific treatment or cure for the disease. Although in the minority, some people do recover from infection.

Our suggestions include:

Maintain your electrolytes(电解质) and body liquid. Sports drinks can be used. Monitor your blood pressure and control it if necessary. Dropping blood pressure may be a serious sign of infection. Breathe in an oxygen-rich environment. Quickly address any symptoms of infection. Be honest about when and where you’re feeling pain.

Small endangered animals are often hard to find in their natural habitats, making it difficult for scientists to monitor them and develop conservation plans. But new technologies can help. Australian researchers have equipped flying drones with infrared cameras so they can spot koalas hiding high in trees.

Koalas spend most of their lives in eucalyptus trees, whose leaves are their favorite food. Since the leaves are low on calories and nutritional content, koalas are not very active - they sleep up to 20 hours a day. Curled-up in high branches, they are not easy to spot from the ground, and they have few natural predators. The greatest threat to this iconic symbol of Australia is logging.

“Every single tree in Australia right now, needs to be protected and unless that happens I can promise you the koala is going to go to extinction,” said Deborah Tabart, Australian Koala Foundation.

Scientists studying koalas say one of the keys for saving the animals is to know where they live and how many of them are left.

Using drones fitted with infrared cameras to conduct a census was an untested concept. Queensland Institute of Technology technician, Gavin Broadbent, said they were skeptical at first. “But when we saw the images come through, we saw the koalas were very distinct compared to the trees and the environment. So we thought, yes this is absolutely a proof of concept that could work,” he said.

The images beamed back to a computer clearly show the animal’s position, even from a distance far enough away not to disturb its sleep.

“We have tested at 20 meters and 80 meters. At 20 meters we get really good resolution,” stated Felipe Gonzalez, project leader.

The remotely controlled camera pivots and swivels, so scientists can scan the trees from all angles, picking out koalas even in the most dense areas, not visible to researchers on foot.

“So this will drastically reduce the manpower," said Amber Gillett, a veterinarian with the Australia Zoo. "Will greatly increase the area that can be covered to survey koalas and in areas where people may not be able to walk through because of dense undergrowth.”

Scientists say it is now clear that drones with infrared cameras can be used for spotting, and perhaps saving, other animals in the wild.

【1】What is an important factor in protecting the animals according to the passage?

A. To know how they live and how many of them are left.

B. To protect the place they live in.

C. To learn their positions and their number.

D.To stop killing them by educating people.

【2】What is the meaning of the underlined word “logging”?

A. cutting B. hunting C. killing D. destroying

【3】Which is not the advantage of drones with infrared cameras?

A.They can take photos of animals from a distance far away.

B.They can help reduce the manpower.

C. They can scan the trees from all angles.

D. They can send the images back to a computer.

【4】What is the main idea of the passage?

A. Koalas in Australia have been found by drones with infrared cameras.

B. New technologies can be used in drones to set up environment suitable for endangered animals.

C. Drones with infrared cameras can be used to save small endangered animals.

D. The functions of the remotely controlled camera are proved.
