Nowadays a vegetarian lifestyle is becoming more and more popular. Leading health experts agree that maintaining a vegetarian diet is one of the best things we can do for ourselves and our families.

1. . A well planned vegetarian diet provides us with all the nutrients we need and avoids fat, cholesterol(胆固醇) and the pollutants found in animal flesh, eggs, and dairy products. And it can provide protection against various kinds of diseases, including the three biggest killers: heart disease, cancer, and strokes. The American Dietetic Association states that vegetarians have lower rates of death from heart disease, lower blood cholesterol levels, lower blood pressure and lower rates of hypertension(高血压) . 2. .

Scientists have also found that vegetarians have stronger immune systems than their meat eating friends. 3. Vegetarians live, on average, 6 to 10 years longer than meat eaters.

4. . Animals raised for food consume the vast majority of their calories simply in order to live, just as we do. We feed more than 70 percent of the grains and cereals we grow to farm animals, and almost all of those calories go into simply keeping them alive, not making them grow. Only a small amount of the calories consumed by farm animals are actually turned into the meat that people eat .So it’s really a huge waste, isn’t it? Try your best to find tips for maximizing(最大化) the health benefits of a vegetarian diet. 5.

A. All of these diseases are more likely to happen to meat eaters

B. Living on plants also saves energy

C. Growing all the crops needed to feed animals requires massive amounts of water and land

D. This means that they are less likely to be affected by everyday illnesses like the flu.

E. Vegetarian diets are the only diets that work for long term weight loss

F. It’s never too late to turn over a new page.

G. Healthy vegetarian diets support a lifetime of good health.

The 115m Christmas Bird Count is officially underway. The count is an annual investigation of local and migratory(迁徙的)birds and it's organized by the National Audubon Society. From December 14 to January 5, volunteers will gather in more than 2,000 locations in North, Central and South America to count the birds in their area.

Each count takes place in a circle about 24 kilometers wide. The volunteers follow specific routes within the circle and record the number of individual birds and the different species they see there in a single day. The results are sent to the National Audubon Society and later published on Audubon's Christmas Bird Count website. The data collected during the bird count is a key source Of information for ornithologists, scientists who study birds.

This information is used to develop conservation programs to protect bird habitats and the environment /n general. Data from the bird count was also used to determine that three species-the Western screech owl, the rusty blackbird and the Newfoundland red crossbill - should be added to Canada's list of species at risk.

The annual bird count was created to protest another Christmas tradition at the very beginning .in the United States in the 19th century, people would often hold "side hunts" on Christmas Day.

Teams of hunters would compete to see who could kill the most birds or other animals that day. In December 1900, Frank Chapman, an American ornithologist, suggested that instead of hunting birds, people should count them.

Twenty-seven people in 25 locations joined in the first Christmas bird count Last year, more than 70,000 volunteers took part. This year, counts are scheduled to take place in 17 countries, ranging from the Arctic to the Antarctic, with most located in Canada and the United States .instead of taking place only on Christmas day, counts are now held on different days for different areas.

1. How long will the 115th Christmas Bird Count last?

A. About 3 weeks. B. A single day.

C. About a month. D. About 2 weeks.

2.What can we know about the Christmas Bird Count from the passage?

A. It was organized monthly by the National Audubon Society.

B. It was launched by Frank Chapman, a Canadian ornithologist.

C. Its results can be seen on Audubon's Christmas Bird Count website.

D. Only 25 people in 27 locations took part in the first Christmas Bird Count.

3.Why was the Christmas Bird Count established at first?

A. To help the scientists who study birds carry out their study.

B To protest the Christmas tradition "side hunts" on Christmas Day.

C. To determine whether the rusty blackbirds are endangered animals.

D To protect bird habitats and the environment from being destroyed

4.What is mainly talked about in Paragraph 5?

A. The brief introduction to the Christmas Bird Count

B. The origin of the Christmas Bird Count.

C. The purpose of the Christmas Bird Count.

One day,when 12-year-old Sean Redden went to a popular chat room on the Internet, he saw the name of someone he’d never seen there before, Susan Hicks. Her message was “ Would someone help me? I can’t breathe. Help me! I can’t feel my left side.”

At first, Sean thought it was a bad joke and he told his mother Sharon Redden. But she asked, “ It’s not just some game, is it?

The message was not a joke. “ Susan Hicks” was actually 20-year-old Taija Laitinen, a student working late at night at a college library near Helsinki, Finland---almost 7,000 miles away from Sean’s home in Texas. While searching the Internet, she began to feel terrible pain all through her body. The library was empty and the nearest phone was outside in the hallway. She couldn’t move that far because any movement caused the pain to get worse. Then as the pain became worse, she began typing her message for help in the chat room.

“I don’t think it’s a joke, mom,” Sean said. He typed, “ Where are you? The letters appeared, “Finland.” Sean and Sharon couldn’t believe it. Not knowing what else to do, Sharon called the local police and explained the situation to officer Amy Schmidt. Schmidt told Sharon to try to get the sick girl’s phone number and address.

Meanwhile, the Texas police called the international telephone operator and asked to be connected to the proper agency(机构) in Finland. The Texas police explained the situation and gave Susan’s address to the Finnish operator. When Sean heard that, he typed, “Help is on the way.”

In the few minutes, the library door opened. Doctors and three policemen ran in. Taija turned once more to the computer, “ They are here. Thanks. Bye-bye.”

3.What can we learn from the text?

A. The policeman Sean’s mother called was in Finland.

B. Susan Hicks was a friend of Taija Laitinen.

C. Sean and his mother offered help in time.

D. Sean had seen Taija Laitinen before.

4. 4.What does the underlined phrase “ on the way.” refer to?

A. There is a way B. to be arriving soon

The global population is living longer,and getting older,which presents new challenges. “The question becomes:who will take care of everyone? While people will always be the best caregivers for people,there just aren’t enough people. That’s where robotic technology can really make a difference,” says Professor Maja Mataric at the University of Southern California.

Her group is developing robots to work with stroke (中风) patients and elderly people. The research team has found that people react well to a robot gym instructor,and seem to get less frustrated with it than with instructions given on a computer screen. The robot can act as a perfect trainer,with infinite(极大的) patience.

“People say things like ‘I prefer this robot to my husband!Can I take it home?’” according to Professor Mataric. “In fact there’s a really important point here. As we create these care giving technologies,we’re helping not only the people that need the care,but also the people caring for them. We can give them a break,and help them avoid burnout.”

People are going to have to like,and importantly trust robots before they welcome them into their homes,and several groups around the world are working on making it easier to communicate with them.

Much of human communication takes place through body language. Gestures, eye contact , and concepts of personal space are all things that robots are being taught. In learning about how people interact(互动) with machines,researchers are also discovering new roles for robots in our lives. Robots can communicate with humans in ways that other technologies can not.

“If someone finds the robot to be more persuasive and more reliable,that’s going to affect how they interact with it,” says Dr Cynthia Breazeal, director of the Personal Robots Group at the Massachusetts Institute of Technology. “We can now start to think about fields where it’s the social interaction,which is the main means by which a robot helps someone.” Dr Breazeal says that means robots could be used in education,learning,and health care,where social support is important.
