Most people around the world are right-handed. This also seems to be true in history. In 1799, scientists studied works (作品) of art made at different times from 1,500 B. C. to the 1950s. Most of the people shown in these works are right-handed, so the scientists guessed that right-handedness has always been common through history. Today, only about 10% to 15% of the world’s population is left-handed.

    Why are there more right-handed people than left-handed ones? Scientists now know that a person’s two hands each have their own jobs. For most people, the left hand is used to find things or hold things. The right hand is used to work with things. This is because of the different work of the two sides of the brain (大脑). The right side of the brain, which makes a person’s hands and eyes work together, controls (控制) the left hand. The left-side of the brain, which controls the right hand, is the center for thinking and doing problems. These findings show that more artists should be left-handed, and studies have found that left-handed-ness is twice as common among artists as among people in other jobs.

    No one really knows what makes a person become right-handed instead of left-handed. Scientists have found that almost 40% of the people become left-handed because their main brain is damaged (损害) when they are born. However, this doesn’t happen to everyone so scientists guess there must be another reason (原因) why people become left-handed. One idea is that people usually get right-handed from their parents. If a person does not receive the gene (基因) for right-handedness, he/she may become either right-or left-handed according to the chance (偶然性) and the people they work or live with.

Though right-handedness is more common than left-handedness, people no longer think left-handed people are strange or unusual. A long time ago, left-handed children were made to use their right hands like other children, but today they don’t have to.

1. After studying works of art made at different times in history, the scientists found ________.

2. How many people in the world are left-handed now?

    A. Less than one sixth.　　　　　　　　　　    B. More than a half.

3. What is the left hand for most people used to do?

    A. It’s used to find or hold things.

    B. It’s used to work with things.

    C. It’s used to make a person’s eyes work together.

    D. It’s the center for thinking and doing problems.

4. According to (根据) the passage, which of the following is NOT true?

    A. No one really knows what makes a person become right-handed.

    B. Left-handedness is cleverer than right-handedness.

    C. Today children are not made to use their right hands only.

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.
【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
