題目列表(包括答案和解析)

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?

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.

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.

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

4.What is the best title of this passage?

A.Future Farming

B.Genetic Engineering

C.Foods with a Difference

D.Genetically Engineered Fruits

Conor Grennan was unwilling to be a volunteer(志愿者). The 29-year-old American was not sure if he had the skills or a strong feeling for it.
However, he went to work at an orphanage(孤兒院) in Nepal. His first thought was to make people impressed.
"I thought that if I volunteered just once. I could retell the story over and over," Grennan said in a Huffington Post article.
However, his three-month stay it the orphanage turned into in unusual experience. It was 2004 and Grennan had given up his job to begin a year-long around-the-world trip, His first three months were spent in Nepal.
When he arrived in the village, he knew nothing about the children or the local culture. When he opened the gate of the Little Princes Children's Home, he was faced by the excited children.
The young American ended up caring for 18 children. He later discovered that they were trafficked(被拐賣的)children. So he walked through the mountains with great difficulty to find the kids' families, "I started walking with photos of the kids." he told the Reuters reporter. "I would show up in villages and show photographs around. I went with 24 photos, and I found 24 families."
At the same time, he put his heart into Nepalese culture.
Grennan said, “Volunteering is the single best way to see how the rest of the world lives.”
He also encouraged others to do what he had done. He believes that volunteering needs only making decisions to show up.
Grennan's fight against child-trafficking has changed him. His book, Little Prince, came out last week.
