Carrot juice is one of the richest sources of vitamin A that can be used in the daily diet. Lack (缺乏) of vitamin A can cause dryness and damage to the skin, nails and hair. Drinking carrot juice to increase the vitamin A in the diet is said to be good for many parts of the body, including the bones and teeth.
Drinking carrot juice is thought to be extremely helpful to the liver (肝脏), because vitamin A helps to clean the liver and reduce fat in it. And it is suggested that drinking carrot juice should be done regularly, rather than just from time to time.
Drinking carrot juice is also thought to improve the eyesight because of the vitamin A in the juice. Lack of vitamin A can lead to night blindness, which can be very dangerous, especially when the person is driving a car. An easy way to find out if you are lacking in vitamin A is to walk from a bright room into a dark room. Your eyes may have some trouble in getting used to the change of light if you are lacking in vitamin A.
How can you make carrot juice? Wash some carrots well in cold water. Scrape (刮) them lightly, but do not peel them, as this will take away valuable vitamins and minerals that lie close to the skin.

举一反三
Now I don"t expect my children to eat healthy food because I like brown rice, beans, and fresh vegetables. I"m glad to cook traditional meals of meat and potatoes for them. I really can"t be too upset with the kids because most adults aren"t careful about what they eat. The other night, my wife and I went to a party where there was plenty to drink but very little for us to eat. They served hot dogs and hamburgers. I can"t eat hot dogs, with all those preservatives(防腐剂), and hamburgers are filled with chemicals so that they look better. Besides the meat, they had sugar-filled cookies and cake, and of course, chips. I don"t want the world to change because of me, but I think people should realize that there are alternatives(选择) to eating meat. They always tell me that I probably don"t get my essential(必要的) proteins. I feel better than ever and I"m sure that it"s because I"m a vegetarian(素食主义者). I would really like to see more television advertisements which show the benefits of good, healthy, natural food.
小题1:According to the passage, it seems that ______.
A.canned food is the only one that the kids enjoy most. |
B.the children like to have fried chicken only. |
C.the kids prefer to have cold drinks, not junk food |
D.the children like nothing better than junk food: cookies and chips |
A.Television influences children’s food choice |
B.The author is not single and he eats meats |

D.It is certain that beans and spinach are not junk food |
A.why he goes to the party | B.whether he gets enough proteins |
C.whether he allows his children to eat meat | D.whether he is healthy and strong |
Even people who spent just a few hours a week on the Internet experienced more depression(沮丧) and loneliness than those who used Internet less frequently, the two-year study showed. And it wasn’t that people who were already feeling bad spent more time on the Internet, but that using the Net actually appeared to cause the bad feeling.
Researchers are puzzled by the results, which were completely the opposite to their experiences. They expected that the Net would prove socially healthier than television, since the Net allows users to choose the information and to communicate with others.
The fact that Internet use reduces time available for family and friends may explain the drop in well-being, researchers supposed. Faceless, bodiless “virtual” communication may be less psychologically satisfying than actual conversation, and the relationships formed through it may be shallower. Another possibility is that knowing the wider world via the Net makes users less satisfied with their lives.
“But it’s important to remember this is not about the technology; it’s about how it is used,” says psychologist Christine Riley of Intel, one of the study founders. “It really points to the need for considering social factors in terms of how you design applications(应用) and services for technology.”

A.Internet May Cause Depression |

People have strange ideas about food. For example, the tomato is a kind of very delicious vegetable. It is one of useful plants that can be prepared in many ways. It has rich nutrition and vitamin in it. But in the 18th century, Americans never ate tomatoes. They grew them in their gardens because tomato plants are so pretty. But they thought the vegetable was poisonous (有毒的). They called tomatoes “poison apples.”
President Thomas Jefferson, however, knew that tomatoes were good to eat. He was a learned man. He had been to Paris, where he learned to love the taste of tomatoes. He grew many kinds of tomatoes in his garden. The President taught his cook a way for a cream of tomato soup. This beautiful pink soup was served at the President’s party. The guests thought the soup tasted really good. They never thought their president would serve his honored guests poison apples. Jefferson never spoke to his honored (忠实的) guests about the fact.
小题1:From the passage we know all the honored guests invited by Jefferson were .
A.people from other countries | B.from France |
C.people of his own country | D.men only |
A.Americans never ate tomatoes after they began to plant them. |

A.the President himself | B.a French cook |

Yet, these additives remain in our food, and it is difficult to know which things on the wrappings(包装)of foods are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to their animals, and because of this, penicillin has been found in the milk of cows. Sometimes similar tings are supplied to animals not for their health, but just to make a profit.
The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although some countries have tried to control such things, the practice continues.
小题1:Which of the following is not true?
A.Some wrappings of food are harmful. |
B.Farmers try to make more money on the market by fattening their animals. |
C.“The practice continues” means “things are still going on like that”. |
D.We needn’t take care of what we eat. |
A.perhaps most of human illness is caused by what we eat |
B.perhaps most kinds of cancer are related to what people eat |
C.cancer was discovered in 1945 |
D.science has made food unfit to eat |
A.harmful | B.useless | C.helpless | D.dangerous |
A.are bright and colourless |
B.are not bright and colourful |
C.have indirect effects on our health |
D.have direct effects on our health |
With so much nutritional knowledge easy to find, we cannot simply ignore our present obesity epidemic(流行病). We know that fruits and vegetables are rich in vitamin. Though we are overweight, many of us choose junk food over healthy food out of habits. One explanation for our strong desire for junk food is that we learn to connect junk food with positive feelings when we are young, and changing this attitude requires a huge amount of confidence and determination. Fortunately, new research published in May 2012 has shown a simple and accessible way to make healthier food choices- the one that doesn’t rely on great determination.
The research was based on two separate studies and it was carried out by T. Bettina Cornwell of the University of Oregon and Anna R. McAlister of Michigan State University. In the first study, 60 adults between the ages of 19 and 23 were questioned about the role of food and drinks. The survey tells us that adults prefer sweetened drinks with high-calorie, salty foods, to sweetened drinks with vegetables.
In the second study, 75 children between the ages of 3 and 5 were gathered for some experiments including drinks served with vegetables. The preschooler experiments were carried out under different situations and on different days. The researchers found that the children chose to take more green vegetables when they were served with water instead of a sweetened drink.
According to Cornwell, children learn to connect high calorie, sugary drinks such as cola, with high fat foods such as French fries, from a very early age. McAlister adds that early taste development appears to play an important role in food choices later in life. Meals served at home and meals offered at restaurants, set the stage for this idea and for the preference to choose junk food over healthy food, when beginning to take sweetened drinks.
“Our taste preferences are heavily influenced by regularly eating particular food and drinking particular drink,” states Cornwell. “If the drink on the table goes against both adults and children eating their vegetables, then perhaps it is time to change that drink… and to serve water with all meals. Restaurants could easily use water as free drink for children’s meals and charge extra money for other drinks.” Both McAlister and Cornwell are confident that serving water with meals could effectively reduce the nation’s obesity rates, diabetes rates and ever rising healthcare costs.
