The food we eat seems to have profound effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat.
Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures.
That food is related to illness is not a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful.
The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this, penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue.
68. What is the best possible title of the passage?
A) Drug and Food
B) Cancer and Health
C) Food and Health
D) Health and Drug
69. Which of the following statements is NOT ture?
A) Drugs are always given to animals for medical reasons
B) Some of the additives in our food are added to the food itself and some are given to the living animals
C) Researchers have known about the potential dangers of food additives for over thirty-five years.
D) Food may cause forty percent of cancer in world.
D) The scientists have preserved the color of meats, but not of vegetables.
70. What are nitrates used for?
A) They preserve flavor in packaged foods.
B) They preserve the color of meats.
C) They are the objects of research.
D) They cause the animals to become fatter.
71. The underlined word “carcinogenic” most nearly means '_____'.
A) trouble-making
B) color-retaining
C) money-making
D) cancer-causing

As an English saying goes, “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 really can 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 heart, 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 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 effect 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.

A．Laughter can make people breathe deeper

【小題2】The underlined word “diminishes” in the third paragraph means “_________”.

A．Because they want to earn more money.
B．Because they think they will help the patients recover from illnesses.
C．Because they want to improve their patients’ health.
D．Because they want their patients to laugh more.
【小題4】According to the author, we should __________ in our life. 
A．laugh as much as possibleB．watch more funny films
C．smile all the timeD．spend time in the laughter clinics

A．Both laughter and physical exercise are good for health.

Given that many people's moods (情緒)are regulated by the chemical action of chocolate, it was probably only a matter of time before somebody made the chocolate shop similar to a drug store of Chinese medicine.

If the CRF seems to be a smart idea, that's because Lee is not merely a seasoned salesperson but also head of a marketing department that has business relations with big names such as Levi's and Sony. That idea surely results in the imagination at work when it comes to making different flavored(味道)chocolates.
The CRF's produce is "green". made within the country and divided into 10 lines, with the Alcohol Series being the most popular. The Exotic Series一with Sichuan pepper, red bean (豆).cheese and other flavors一also does well and is fun to taste. And for chocolate snobs，who think that they have a better knowledge of chocolate than others, the Connoisseur Series uses cocoa beans from Togo, Cuba, Venezuela , and Ghana, among others.

Kenya is the first country to protect elephants by text messages. Mobile phone SIM cards are inserted(插入) in the collars of elephants. The cards will send a text message when the elephants wander too close to farms, allowing wildlife protectors to drive them off rather than shoot them.
Hungry elephants cause big problems for farmers and villagers in some parts of Kenya when they are searching for food. Two years ago the Kenyan wildlife service had to unwillingly shoot five elephants who continued to destroy crops.
In order to prevent such bad activities, the Elephants charity put a mobile phone SIM card on a huge bull elephant called Kimani. The conservationists(自然保護者) then set up a virtual(虛擬的) fence. Each time Kimani came near the fence, a text message was sent to farmers. So far he’s been stopped from going into the danger area fifteen times.
The project seems to be working successfully as Kimani hasn’t come near a farm for four months. A similar system has now been put into operation in another part of the country.
One of the biggest benefits of the project is that elephants seem to learn from one another, which can help a whole group change their habits.
The elephants can also be tracked using Google Earth software. This is also helping the protectors know where to use their resources to protect the animals well.
【小題1】Elephants often cause problems in Kenya, because ______.

A．they are attackedB．they are angry
C．they are sadD．they are hungry
【小題2】What does the underlined word “he” in Paragraph 3 refer to?
A．The protector.B．The writer.
C．The elephant.D．The conservationist.
【小題3】From the passage, we know that ______.
A．the text messages are of little help to the wildlife protectors
B．the project has worked out to be a great success in Kenya
C．a(chǎn) mobile phone SIM card has been put in all the elephants
D．the project has been introduced to all parts of the country
