題目列表(包括答案和解析)

When we talk of plants, most of us will think of things that grow from the ground and have green leaves, but there are plants that do not look or act like other plants. Some of these belong to a special class of plants called fungi.
Fungi may appear almost everywhere. They commonly grow in wet places where they call get food and water easily. Because fungi do not have green leaves to make their own food, but fungi must take their food from animals, other plants or water. Some fungi live on dead or rotting(腐爛的)wood, while others grow on living trees or in dirt or moss(苔蘚). Mushrooms(蘑茹)are the best-known fungi.
There are many kinds of mushrooms appearing in all shapes and sizes. For example, cauliflower(菜花)mushrooms are found in forests from July to October.They can grow to be as heavy as fifty pounds! They grow at the foot of trees Squirrel’s(松鼠)bread is another kind of wild mushroom Its appearance and use Call explain its name. These fungi look like small golden cakes Squirrels can easily eat them or carry them off to their hole to eat later.
The mushrooms found in food stores are carefully grown by people who know they are safe to eat. People are warned never to touch of taste wild mushrooms because some of them are deadly. Even less dangerous ones cart still make a person very sick..
【小題1】Where does Fungi not grow?            .

A.On dry wood
B.In places full of water
C.On living trees
D.Behind houses
【小題2】Where can Fungi take food?            .
A.From their green leaves
B.From water
C.From rotting wood
D.From people
【小題3】Squirrel's bread is a kind of            .
A.treeB.a(chǎn)nimalC.food D.medicine

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(蟲子). 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(過敏). 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(種子)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(殺蟲劑)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?
【小題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.
【小題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.
【小題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
【小題4】What is the best title of this passage?
A.Future Farming
B.Genetic Engineering
C.Foods with a Difference
D.Genetically Engineered Fruits
