The human brain is divided into two sides, or hemispheres, called the right brain and the left brain. The two hemispheres work together, but each one specializes in certain ways of thinking.

Each side has its own way of using information to help us think, understand, and process informa-tion.The left side of the brain controls language. It is more verbal and logical. It names things and puts them into groups. It uses rules and likes ideas to be clear, logical, and orderly. It is best at speech, reading, writing, and math. You use this side of the brain when you memorize spelling and grammar rules or when you do a math problem.

The right side of the brain is more visual and creative. It specializes in using information it receives from the senses of sight, sound, smell, touch, and taste. This side of the brain likes to dream and experiment. It controls your appreciation of music, color, and art. You use this side when you draw a picture or listen to music.Although we all use both sides of our brains, one side is usually stronger or dominant. Some people are more “left-brained,” and others are more “right-brained”. Our dominant side influ-ences the kinds of jobs and hobbies we have. Politicians, artists, architects, and musicians depend on their right brains. Accountants, engineers, doctors, and lawyers usually rely on their left brains.

1.What can we know from the passage?

A. When we speak, we use right side of the brain.

B. Right side of the brain is stronger than left side.

C. We use right side of the brain to do a math problem.

D. Each side of the human brains work in its own way.

2.What does the underlined word “dominant” mean?

For a long time, humans have used technology (科技) to study the world around us, and Mars is the latest place we’re using machines to explore. Besides the earth, the “red planet” is seen, as the one place in our solar system most likely to have life.

Early last month, the first American robot, Spirit, landed on Mars without any problem. Opportunity, the second robot, landed on the planet more than a week ago. Scientists are very excited about these machines’ safe landing on Mars. It means that now we have an excellent chance to look for water and other signs of life. So far, the robots have found some stones that could show Mars was once a wet and warm planet.

But the trips made by Spirit and Opportunity were dangerous. Mars is often called the “death planet”, because in the past its environment has been unfriendly to the robot explorers. Before Spirit and Opportunity, nearly forty spaceships had been sent to Mars since the 1960s. Two-thirds of them failed. The first spaceship, Korabl, sent in 1962 by Russia was among them. It broke apart (分裂) near the earth.

1.For a long time humans think ________.

A. they can surely find life on Mars

B. there may be life on Mars

C. it’s too late for them to explore Mars now

D. Mars is the only planet that has life on it

2.The two robots ________.

A. have found out that it is warm and wet on Mars

B. were sent to Mars to find some stones

C. were the first two American robots that landed on Mars

D. are the only machines that have landed on Mars so far

3.The third paragraph mainly tell us ________.

A. it’s a very hard and dangerous trip for spaceships to Mars

C. Spirit and Opportunity landed on Mars successfully

D. Mars is called the “death planet”

九年级英语单选题困难题查看答案及解析

Do you know how important it is to have breakfast? A study of 2,000 teenagers in the US showed that eating breakfast daily is helpful to young people.

According to the study, teenagers who eat breakfast weigh around 5 pounds less than teenagers who do not. Although they take in more calories (卡路里) in the morning, they are more active during the day because they have more energy. This means they burn more calories than non-breakfast eaters. The breakfast does not even have to be very healthy, as eating anything is better than nothing.

The study also showed that eating breakfast keeps teenagers feeling full for longer, so they will not eat too many snacks (零食) later in the day. This is good news as most popular snacks, like sweets and potato chips, are usually unhealthy and full of calories.

Another big advantage of eating breakfast is that it helps teenagers do better at school.This is because it gives them more energy to keep their attention in class.

What's more, a study in the UK showed that adults (成年人) who eat breakfast daily put on less weight and also perform better at work.

Whatever your age is, take time to have breakfast every day.

1.The underlined sentence in Paragraph 2 means that _________.
