Childhood is a time of fun and games. Many people still remember when they were young, they often played games like hide-and-seek and chess. Playing teaches children how to get along with others, and it also helps to exercise the mind and body. However, children today spent most of their playing time in front of the computer, playing video games.
A recent survey found that in the US children between 8 and 12 spent at least 13 hours a week playing video games or “gaming”. Boys of this age spend even more time, almost 16 hours a week. Although some people will say that gaming is helpful, it brings many problems as well.
One big problem is that kids who spend most of their time on games might have difficulty communicating with real people. They might have trouble sharing and resolving problems because they do not practice these shills when sitting alone at a computer.
Another problem is about health. Game players usually sit for hours without doing any exercise. And they might not eat healthily. As a result, they might be out of shape.
Next, game players might have trouble with their lessons. Many of them spend more time playing games than working on their homework. In the end, _______________.
Finally, it is always possible that the gamers become addicted(成瘾). Some people play four or five hours a day or even all day. This happened to a 28-year-old Korean man. He spent about 50 hours playing an online game without sleeping or eating well. He died while gaming!
This is one example of the dangers of video gaming. It tells us that video gaming, like everything else, should not be done too much. A few hours a week should not hurt, but several hours a day just might be dangerous to your health.

Space travel is nothing new. The first spacecraft with a human was sent up into space in 1961. Since then, people have not only traveled to space, but also many of them have lived there in space stations for some time.
The Soviet Union(前苏联) sent the first space station into space in 1971. This space station was called Salyut 1. Salyut 1 was designed as a place where people could live while they observed space and did experiments. The first group of astronauts lived there for 23 days. The Soviet Union went on to make seven more Salyut space stations. At about the same time, the United States built its own space station, called Skylab.
Astronauts visited and often lived in these space stations for a short time. However, it wasn’t until the late 1980s when The Soviet Union sent the Mir space station that people began to live in space for a longer time. Mir stayed in space from 1989 until 2001, when it was decided that the space station was too old and no longer safe to live in.
Living in space stations seems to be fun, but astronauts face many problems. One of them is food. All the meals on space station are put together on Earth and sent there by space shuttle. Because the food has to last a long time (sometimes up to three months), a lot of it has to be stored in cans. The space station does not have a fridge, but it has a cool room to keep fruit and vegetables fresh. Astronauts also eat many other foods such as dried meat that do not need special care.
Without the help of gravity, sitting down to eat can be tough. Astronauts sometimes have to fix themselves to the wall while eating. They also have to be very careful to that food does not float away.
Which of the following has the closest meaning to the underlined word “observed” in Paragraph 2?

A.Discovered B.Checked C.Watched D.Fixed

What can we infer(推断)from the passage?

A.Astronauts can never have a chance to eat fresh food when they live in space station.
B.The Soviet Union sent a total of 9 space stations into space in the 1970s and 1980s.
C.Astronauts could live in the Mir space station for no more than three weeks.
D.Space travel has quite a long history of more than 60 years.

What is the best title of this passage?

A.Exploring Space B.Space Travel C.Living in Space D.Space Stations

Martin had just finished high school. He would go to college at the far end of the city. He didn’t want to live there, and he didn’t want to take the bus either. So his father agreed to buy him a car.
His father spent all his summer teaching him how to drive, from the ABC to the XYZ. Thinking of the great feeling of driving a new car, Martin learned very quickly, and received his driver’s license just before his eighteenth birthday.

Martin climbed into the front seat. He said excitedly, “It’s my first day driving alone. Dad, Mom, and Poo! Enjoy it!”
His dad immediately took the back seat, right behind the new driver. Martin wondered why his father chose that seat, for his father always enjoyed looking in front.
So he said, smiling, “I’m sure you’re back there to have a change after all those weeks of sitting in the front seat teaching me how to drive.”
“No,” Dad replied, “Do you remember what you did to me all those years when I took you to and from school? I am sitting here to hit and kick the back of your seat all the way!”

Among them, Pride and Prejudice written in 1779 was the most popular. Victor Hugo, born in 1802 in France, was one of the best writers in the19th century. The talent in writing and hard work brought great success to Hugo at an early age. His most popular novel, the Hunchback of Notre-
Dame, was written in 1831. The book was so successful that it was quickly translated into many other languages across Europe. Ernest Hemingway, an outstanding American writer and reporter, was born in 1899. His life experience had a great influence on his writing style.

One terribly cold day, a snowstorm hit our area. Needing firewood, I quickly set out with my best friend, Bruce, to look for a tree to cut down. Cutting down a tree in a snowstorm can be dangerous. (1) So to have a friend who could warn me of dangerso was important.
When I chose a big 23-meter-tall tree and prepared to cut it down, Bruce suddenly warned me, “Don’t cut down that tree! It’s too close to the power line!” I wasn’t sure about it. So I decided to disregard his warning. I couldn’t wait to finish the job and go back home. I began cutting down the tree. (2) When the tree fell, there was no longer any doubt whether my friend was right.
The tree caught the power line, bringing it to the ground. I considered cutting the tree off the line. After all, electricity can’t travel through wood. As I reached out my finger to touch the tree, pain ran up my arm and through my head. I had been shocked!
After I returned home and told my mother what happened, she quickly called the power company. Workers from the power company soon arrived. One of them asked if I had touched the tree, and when I told him I had, his face turned pale. “You should have been killed,” he said. It was my boots that saved my life.
(3)Within two hours, the workers removed the tree. Soon the snowstorm calmed down——but not my mother. Even though she was glad that I wasn’t hurt, my mother was still serious with me. After all(毕竟), I shouldn’t have brushed off my friend’s warning.
