Plant scientists consider them as fruit. Most other people think of them as vegetables. Whatever you call tomatoes, there are many different kinds of this popular and healthy food.
There are two groups of the plants. Small tomato plants grow to about one meter. They can be planted rather close together. Some short kinds do not require special care and are often gotten crop by machines. Large tomato plants can grow over two meters tall. They also produce larger fruits.
People who grow only a few plants can place wire cages around each one. The cage can be made of wire fence material. The cage helps the plant grow taller and produce a better crop.
Tomatoes often need extra calcium (Ca), or the fruits may be ruined. Add lime to the soil can solve this problem. Dry lands may also ruin the fruits. Tomatoes need water regularly. The soil should never dry out completely. Dried grass or leaves placed around the plant can help hold water in the soil and stop the growth of unwanted plants.
Tomatoes are native to South America. The tomato is a member of the potato family. The leaves of the plant are poisonous, like the leaves of its relatives. Before the 18th century, people grew tomatoes only as pretty plants. They called the bright red fruit a “love apple”, but would not eat it.
【小题1】Which of the following is right about the small tomato plants?
A. They can grow to about 2 meters.
B. They can’t be planted close together.
C. Some of them don’t require special care.
【小题2】People place wire cages around the plant in order to ___________.
A. protect the plant from being taken by others.
B. help the plant grow taller and produce a better crop
C. keep the plant from being eaten by animals
【小题3】The underlined word “ruin” probably means “___________”.
A. grow B. destroy C. stop
【小题4】 People often give tomatoes extra calcium by ___________.
A. adding lime to the soil B. watering the plant regularly
C. putting dried grass around the plant
【小题5】What can we learn from the passage?
A. Tomatoes are native to North America.
B. The leaves of the plant can also be eaten.
C. Americans began to eat tomatoes from the 18th century.

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（杀虫剂）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. |
| 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. |
| 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 |
| A．Future Farming |
| B．Genetic Engineering |
| C．Foods with a Difference |
| D．Genetically Engineered Fruits |

B）根据短文内容及首字母提示，填写所缺单词。
A young college student thought that he chose the wrong major (专业) at a common college, so he drank every day and didn’t study at all. He b 1 more and more discouraged.
But he was never a 2 from Professor Yang’s biology (生物) class. He liked the course. Besides, Yang’s class was so i 3 that he always listened carefully, never caring about w 4 the other students were paying attention or not in class.
Once he put a note in the homework he handed in, saying: “Professor, it is said that today’s college students are c 5 than potatoes. Do you agree?”
That day Professor Yang sent for him after class. When he came, he f 6 the professor at a table with food on it. They drank happily over their meal.
When they became half drunk, the professor took out a small potato that was sprouting (发芽的). “Do you know how much this c 7 ?” he asked the young man. “It’s soft but poisonous. N 8 will take it even if it’s free. ” He then threw the potato away.
The professor then showed him another potato. It was half the s 9 of a football and perfectly round. “This potato is organic (有机的). It is not only large and fresh but also free of pollution. People are in need of such k 10 of potatoes and they’re quite expensive.”
The young man was impressed by what he’d heard. “Be such a potato,” said the professor.
