Here is an astonishing and significant fact：Mental work alone can't make us tire. It sounds absurd. But a few years ago，scientists tried to find out how long the human brain could labor without reaching a stage of fatigue (疲劳). To the amazement of these scientists，they discovered that blood passing through the brain，when it is active，shows no fatigue at all!
If we took a drop of blood from a day laborer, we would find it full of fatigue toxins at and fatigue products. But if we took blood from the brain of an Albert Einstein, it would show no fatigue toxins at the end of the day.
So far as the brain is concerned，it can work as well and swiftly at the end of eight or even twelve hours of effort as at the beginning. The brain is totally tireless.So what makes us tired? Some scientists declare that most of our fatigue comes from our mental and emotional attitudes.One of England’s most outstanding scientists，J.A.Hadfield，says，"The greater part of the fatigue from which we suffer is of mental origin. In fact，fatigue of purely physical origin is rare."Dr.Brill，a famous American scientist, goes even further，He declares，"One hundred percent of the fatigue of sitting worker in good health is due to emotional problems."
What kinds of emotions make sitting workers tired? Joy? Satisfaction? No! A feeling of being bored，anger, anxiety，tenseness，worry，a feeling of not being appreciated—those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.

Does your pet have a slim figure? According to the Association of Pet Obesity Prevention (APOP), about half of all dogs and nearly 60% of all indoor cats are overweight. Larry Kornegay, president of the American Veterinary Medical Association, says he sees an overweight pet nearly every day, and unusually the owner is overweight. So talking about the topic can be touchy. “I talk about their pet’s health. Still, some clients take it personally.”
Here are some tips for pet weight loss:
See the vet(兽医). Have your vet put together a plan and treat any existing medical problems. Pain relief and diet changes may be required for arthritic(患关节炎的) pets, which will allow for exercise to at least begin.
Skip the crash diet (an attempt to lose weight quickly by strictly limiting the diet). A special weight-loss diet may be suggested. For example, look for the supplement which burns fat and builds muscle mass in foods. Never place any pet on a crash diet, especially cats, which can suffer a potentially fatal liver disease as a result. There’s a safe weight-loss drug for dogs you can ask your vet about.
Dine alone. “Cut out treats and resist temptation by keeping pets out of the room you’re dining in,” says Chicago vet Sheldon Rubin. You can buy low-calorie treats for dogs and cats. Rubin also recommends mini carrots, small apple slices or blueberries for dogs. What’s important is finding other ways, aside from food, to show your love. Play with your cat using an interactive toy, and take your dog for walks. Walks are great for bonding, and good for you. Studies show people are actually more willing to lose weight themselves if it also will help their pet.
Feed pets at special times. Pre-measure food carefully—don’t give them a larger meal than ever—and leave it in various places, so pets sniff it out and use the stairs. It’s fun, and it’s good exercise.. The underlined word “touchy” in Paragraph 1 probably means__________
| A．sensitive | B．exciting | C．moving | D．pleasant |
.

| A．Overweight people usually like overweight pets. |
| B．Pets’ weight is easier to lose than humans’. |

| D．Overweight people often ignore their pets’ weight. |
Which of the following methods is healthy for your pets?
| A．Providing them with mini carrots or blueberries. |
| B．Keeping them with you when you’re dining. |

If you plan on visiting to Fiji, you are probably looking for some fun things to do. Below are four unusual places.
The Poseidon Resort
The Poseidon resort is an underwater resort that gives visitors a beautiful view of sea life. This resort covers 255 acres. It’s covered and surrounded by a lagoon (咸水湖) that covers 5,000 acres and is about 90 feet under water, giving you a beautiful view of sea life righ
t before your eyes. This resort even has a hotel for those who would prefer to have the unusual experience of sleeping and waking up to the beautiful scenery all around them.
The Sabeto Mud Pool
If you’re looking for something unusual to do, you can’t pass up the mud pool at Sabeto. It is located in a mountain range with a huge group of Geothermal (地热的) pools full of nice, warm mud.

As we all know, any country has good reasons to want its citizens to be as healthy as possible. This led to the introduction of a health service in many countries. France has developed into a country in which all citizens can get most of the health treatment free. The money for this is partly from the people who are willing to offer.
But there are different opinions about the Health Service. The number of patients treated every year and the cost of treatment are much greater than expected. This means that the people who work for the Health Service --- doctors, nurses and other hospital workers, have much more work to do, and as a result they have little time for preventive treatment.
However, the tough problem is that as many people are able to receive treatment more expensive than they can pay, sometimes people go and visit their doctors when they don’t really need to. As there are many patients, doctors cannot spend time long enough with each patient. So some people prefer to pay for their own treatment so that their doctors can examine them more carefully. In fact, some rich people feel that they should pay more free money, which would be given to other citizens. France is described as an example to show that __________.
| A．people have to pay part of the medical care |
| B．everyone in France enjoys free medical care |
| C．it is a country with the Health Service |
| D．it is a very rich country in Europe |
What is the problem in the Health Service?
| A．Money is not enough to employ more medical workers. |
| B．There are not enough well-treated doctors. |
| C．People can get more preventive treatment. |
| D．Doctors and nurses are not working hard. |
Why do many people go and see the doctors even when they really don’t need to?
| A．To keep himself even more healthy. | B．To receive treatment free of charge. |
| C．To take back some expensive medicine. | D．To get necessary protective treatment. |
What can we infer from the last paragraph?
| A．The Health Service is quite successful so far. |
| B．People should not go to the doctors unless necessary. |
| C．There is much to improve the Health Service. |
| D．The rich should be allowed to pay for the treatment. |
In many countries today, laws protect wildlife. In India, the need for such protection was realized centuries ago.
About 300 B.C. an Indian writer described forest that were somewhat like national parks today. The killing of game beasts was carefully supervised(监视). Some animals were fully protected．Within the forest, nobody was allowed to cut timber(wood for building), burn wood for charcoal(炭), or catch animals for their furs. Animals that became dangerous to human visitors were caught or killed outside the park so that other animals would not become uneasy.
The need for wildlife protection is greater now than ever before. About a thousand species of animals are in danger of extinction, and the rate of extinction was about one species every fifty years from A.D. 1 to 1800, but now it is about one species every year. Everywhere, men are trying to solve the problem of protecting wildlife caring for the rapid growth of the world’s population. In forest of ancient India __________.

Dangerous animals were caught or killed outside the park so as to __________.
| A．keep human visitors safe | B．free the rest of the animals from worry or fear |
| C．both A and B | D．supply other animals with more food |
The underlined word “extinction” probably means __________.
| A．being hungry | B．dying out | C．growing slowly | D．being killed |

As prices and building costs keep rising, the “do-it-yourself”（DIY）trend in the US continues to grow.
“We needed furniture for our living room,” says John Ross, “and we just didn’t have enough money to buy it. So we decided to try making a few tables and chairs.” John got married six months ago, and like many young people these days, they are struggling to make a home at a time when the cost of living is very high. The Roses took a 2-week course for $280 at a night school. Now they build all their furniture and make repairs around the house.
Jim Hatfield has three boys and his wife died. He has a full-time job at home as well as in a shoe making factory. Last month, he received a car repair bill for $520. “I was deeply upset about it. Now I have finished a car repair course, I should be able to fix the car by myself.”
John and Jim are not unusual people. Most families in the country are doing everything they can to save money so they can fight the high cost of living.
