The Development of Electric Cars
Electric cars may seem like a recent invention, but they have been around for years. In the early 1900s, there were 1 electric cars on the road than gasoline (汽油) cars, because at that time, gasoline was expensive compared with other fuels (燃料) , electric cars were more popular.
When gasoline 2 dropped and new technologies on gasoline cars were developed, electric cars were out of date. Gasoline cars became more popular 3, because they could go farther without stopping.
During the 20th century, gasoline cars got bigger, heavier and faster. They needed more fuel, and it 4 more air pollution. For years, the car makers didn't worry about pollution. They didn't worry about how much gasoline cars used, either. But when people began to 5 that there was not enough oil on the earth, they asked car makers to produce more efficient (高效能的) and less polluting cars.
One 6 of solving the problem was a "hybrid" car (混合动力车) , one that ran partly on gasoline and partly on electricity. Hybrid cars became popular in the 2000s because gasoline prices went up while prices of hybrid cars went 7.
An all-electric car uses no gasoline. The problem, however, is that car batteries (电池) need to be recharged (再充电). That makes electric cars not so 8 for long journeys. Many people are not pleased with it. The government and car makers are working together to 9 safe, cheap and useful electric cars. When more and more people have these electric cars in the future, a gasoline station may 10.

Wang Hua is a twenty-year-old young man. Two years ago, he finished middle school and found a job in a shop. Usually he works until 9 o'clock at night. He is very tired when he gets home. After a quick supper, he always goes to bed quietly. His grandma who lives downstairs is happy with this.
One day, on his way home, he happened to meet Zhou Weilun. They were both happy because they hadn't seen each other since graduation. They talked about their school, teachers, classmates and their future. They couldn't stop and went to Wang Hua's house together with some fruit and drinks. They went on talking there.
"Have a look at your watch, Wang Hua. I left mine at home," Zhou Weilun said. "What time is it? Maybe I should go home."
"Sorry, but there is something wrong with my watch," said Wang Hua.
Wang Hua thought for a while and began to stamp (跺) his foot on the floor. "Bang! Bang! Bang!"
The sound woke up his grandma. The old woman shouted, "It's twelve o'clock at night, Wang Hua. Why are you still jumping upstairs?"
Sleep is a physical and mental (精神的) need. We all need to sleep, though the sleep hours are different from person to person. Doctors do not know why we need sleep, but they all agree that sleep is very important to us. Without enough sleep, the body may be weak.
One-third of adults have sleeplessness. There are over 80 kinds of sleep-related disorders (失调) . However, other adults are lucky and have no sleeping problems. They sleep as soon as their heads hit the pillows. Do you sleep well? If you have sleeplessness, here are a few suggestions.
⒈ Make a timetable, and stick to it.
We need to sleep at regular times. If your bedtime and wake-up time change from day to day or on weekends, your sleep rhythms (节奏) aren't predicted and the body doesn't know how to act. So it's important to have a regular wake-up time, even on weekends, vacations or after a night of poor sleep.
⒉ Don't lie in bed awake.
"The best sleep tip you can give somebody is to get up—don't lie in bed awake," sleep expert Grandner said. "Whether it's the beginning of the night or the middle of the night, if you've been awake for 20 or 30 minutes, get up and reset (重新调整) . Maybe you just need five minutes to get sleepy, or maybe an hour, but don't spend that time awake in bed."
⒊ Change your thinking about sleep.
"Many people regard sleeping as the final thing they have to do for daily activities. They would like to work or watch TV very late rather than sleep on time. That thinking needs to be changed." Grandner said.
"Don't see your sleep as the time you have left in your day," he advised. "See your sleep as the time you need in order to prepare yourself for an energetic (精力充沛的) tomorrow."
"It may sound like a small change in thinking, but it's an important one." Grandner added.
To Borrow Arrows with Thatched Boats
One day, Zhou Yu ordered Zhuge Liang to make 100,000 arrows (箭) in ten days. Zhou Yu thought it was impossible, but Zhuge Liang said, "Give me three days." Then he asked Lu Su to lend him 20 boats, and the soldiers put some scarecrows (稻草人) in line on the boats. He reminded Lu Su not to tell Zhou Yu what was happening.
When Lu Su came again to see Zhuge Liang, he found nothing unusual. Nothing happened on the second day, either. In the small hours (凌晨) of the third day, Zhuge Liang invited Lu Su for a boat ride. The 20 boats were tied together with strong ropes. Zhuge's fleet went towards the camp of Cao Cao. The surface of the river was covered with thick mist (雾) all over. People could hardly see each other on the river. When Zhuge's fleet got close to the Cao camp before dawn (黎明) , Zhuge Liang ordered his soldiers to shout and beat drums heavily to pretend an attack. But Zhuge and Lu Su only sat inside one boat drinking wine to enjoy themselves.
As soon as the Cao camp heard the shouting and drum beating, they mistook it for a surprise attack by the Zhou Yu camp. Since they could see nobody on the river, they had to order 3,000 soldiers to shoot arrows to stop the unexpected attack. The front of the scarecrows was quickly full of arrows. After a while, Zhuge Liang had his fleet turned around to get the other side of the scarecrows to face the Cao camp. When both sides were full of arrows, the day broke. Zhuge Liang ordered his soldiers to return. The soldiers shouted in excitement, "Thank you, Cao Cao, for your arrows." After they got back to their camp, they collected more than 100,000 arrows in total from the scarecrows.
Do you know how music influences the lives of people? Researchers did a survey about it. Over 36,000 volunteers joined in the survey and experienced many different kinds of music. Then the volunteers offered information about their personalities (性格) .
Pop Music. While pop music lovers are hard-working and have high self-esteem (自尊) , researchers suggest that they may be easy to get worried.
Rock or Heavy Metal Music. When it comes to this kind of music, sometimes aggressive image (好斗的印象) about rock and heavy metal music may show up in our mind. They can be creative, but are often shy.
Classical Music. Classical music lovers are shyer. Those who are quiet may prefer to enjoy classical music.
People usually believe that rap lovers are more aggressive, but researchers have found there is no such relationship between them. They say rap fans are usually outgoing.
In my opinion, this research helps you know yourself and others better.
A. They feel comfortable with themselves and the peaceful world around them.
B. Rap or Hip-Hop Music.
C. Different people have different opinions on music.
D. Here are the results about the survey.
E. However, researchers found that fans of this kind of music are usually very gentle.
F. Fans of pop music are possible to be outgoing and honest.
