Sugar—free beets(甜菜)that still taste sweet, tastier tomatoes and brighter-colored fruits and vegetables that stay ripe(熟的)longer are all foods that are being grown now. How can they
carry traits, such as being tastier, brighter, and riper? They are genetically engineered.
Genetic engineering(基因工程)is like making a change in a recipe. For example, when you make cakes, you mix together all of the usual ingredients. If you add an extra ingredient, like salt, the cakes will taste differently.
Genes are ingredients in the recipe for life. They carry the traits of living things. Your genes dictate what color hair and eyes you’ll have, how tall you’ll be, as well as many other traits. Genes carry traits for plants, too. By adding genes to a plant, you can sometimes create new traits. For example, adding a certain gene to a potato plant can make the potato plant distasteful to bugs(虫子). This makes some farmers happy because they don’t have to use chemicals to keep bugs away from their plants.
It sounds great, but some people are opposed to the idea of food that is genetically engineered. Ronnie Cummins, from the Campaign for Food Safety, is against it. He says that one of the major concerns is allergies(过敏). Supermarkets don’t always label foods that are genetically engineered. A customer could unknowingly buy food that has an added gene from another plant that he or she is allergic to. It could be dangerous.
Gary Burton from Monsanto, a seed(种子)company that engineers food, disagrees. He says his company tests for allergies. Burton believes that genetic engineering is a valuable tool for making better food. The technology can help farmers use less insecticide(***虫剂)and grow healthier crops. Burton thinks there are many advantages.
But Cummins says that we just don’t know what will happen in the future if we keep adding genes to foods. We could mistakenly create a monster.
People have different opinions about genetic engineering. One side supports it and thinks it will only help us. The other side is opposed to playing with nature and fears health risks. Which side do you think is right?
小题1:What could be a good thing about food that is genetically engineered?
A.It’s more expensive.
B.It could taste different.
C.It requires less insecticide.
D.It’s not labeled in the supermarket.
小题2:In general, who does not support the idea of genetic food?
A.People from seed companies.
B.Farmers who use engineered seeds.
C.People from the Campaign for Food Safety.
D.Scientists who create genetically engineered food.
小题3:It can be inferred that          .
A.growing genetic foods will make farmers richer
B.people will eat more genetic foods in the future
C.using fewer chemicals could make the food tastier
D.there could be unknown dangers about genetic foods
小题4:What is the best title of this passage?
A.Future Farming
B.Genetic Engineering
C.Foods with a Difference
D.Genetically Engineered Fruits

Chinese space trainer Wang Yuan has been chosen as one of the volunteers for the Mars-500 test project. He was very happy to be chosen and will accept the meaningful challenge(挑战) Another five volunteers are all space lovers., including three Russians, an Italy-Colombian and a Frenchman. They are about to feel what it’s like to travel to Mars, only without leaving the earth. They are locked up together for a year and a half under a similar condition to the red planet during the whole process. So the experiment is called Mars-500.
When reporters asked what they would miss most during the 520-day special life, French trainer Charles said:”For me, it will be mainly my family, the sun and fresh air.”
The Mars-500 test will be in a special building in Moscow, Russia. Although the people won’t leave the building, they will fell as if they are on a real trip to the Mars. The most difficult thing will be to be separated(分离) from the people that they used to live with. The trainer won’t see sunsets, sunrises, won’t feel rain for 18 months. That will be hard.
The main task is to study the “Man and environment”. It’ll care about the astronauts’ getting experience and physical effects. The 520-day-test is divided into three parts,the first 250days to Mars, the middle 30days of landing on Mars, the last 240 days to return to the earth. Everyone will stay there alone for a long time and will work lonely. They will have to make decisions themselves and only then report to the earth, and the earth will tell them whether they do the right thing or not.
Each astronaut is preparing for the great challenge. It is learned that they will be launched(发射)early in June. And the experiment will end in November 2011.
小题1: _______ members were chosen as volunteers.
A.FiveB.SixC.Three D.Four
小题2: The most difficult thing for the trainers is ______.

C.November D.Xichang
小题4: It will take trainers _______ days to land on Mars.
A.250 B.30 C.240D.520
