1 . Everyone knows that Edison failed 10,000 times before he invented the light bulb (灯泡). It’s important to have new ideas and keep trying. Teenagers are known for being creative and full of new ideas. Let’s have a look at these teenage inventions that might change the world.
Banana leaves usually go bad in two or three days. Tenith Adithyaa, a teenager from India, used UV to make the leaves stay fresh for a year. Tenith thinks that one day the leaves will be used for making plates, cups and other things. | David Cohen, an American teenager, built an earthworm (蚯蚓) robot. It is able to go into the smallest places, where humans or dogs can’t go. It will be used for finding people in a fire or an earthquake. |
Remya Jose, a 14-year-old from India, found it tiring and boring to hand-wash clothes in the nearby river. She reused some bicycle parts and created a washing machine that saves time, energy and keeps people fit at the same time. | Kenneth Shinozuka, a 15-year-old from New York, noticed that his grandfather who got Alzheimer’s disease (阿尔茨海默症) would often leave home and get lost. So he invented the wearable sensors (感应器) to help people find their family members like his grandfather. |

2 . About one-third of a person’s life is spent in sleep. Studies have shown that a good night’s rest helps us stay healthy. Researchers say sleep is probably the best tool we have for memory and learning.
“Getting a good night’s sleep is important for the learning and memory. It’s important because it stores the training and learning exercises into our memory forever while we’re sleeping 7-8 hours in bed. And then the next morning when we wake up, our mind is better prepared to act on that information,” Twery, an expert on the science of sleep said.
But what about getting rest during the middle of the day? Past studies have shown that napping (打盹) can help babies and young children learn better. In fact, napping can help older adults with their brain to remember things better.
The researchers studied 3,000 people and found that those who took an hour-long nap did much better on mental (智力的) tests. The hour-long nappers also did better on the tests than those who napped for shorter and longer periods. But researchers note that these findings are for those over 65, but for the young and healthy adults, an hour-long nap may be too long.
“At present, we’re suggesting that we try to nap for about 30 minutes or less. Thirty minutes is enough to remove (消除) the pressure and will help us feel more awake. If we nap longer, we will get trapped into the deep sleep, which can be hard to get out of,” Twery said. This feeling is called sleep inertia (迟钝)—the period when you are awake from a very deep sleep. For a time, you are unable to think clearly.

3 . Do you want to do well in exams? Sometimes your knowledge is not enough; you also need good strategies. Here are some for you:
·Before you answer the questions, if you feel a little nervous, take a few deep breaths (呼吸) to help you relax.
·Always read the question carefully and make sure that you understand it. Read it a few times if possible.
·Find out how much each question is worth or how many points you need.
·If it asks to give one answer, only write one.
·If there is a difficult question, don’t worry. Go on to the next question and come back to it if you have time later.
·Try not to leave questions unanswered when you finish the test. Sometimes a guess may get you points.
·When you finish, go back and check your answers. You will need to check your writing for spelling mistakes.

4 . Confidence is very important in daily life. It is helpful to develop a healthy attitude (态度). A study shows that people who are more confident are much happier. They can have more chance to make themselves successful. But how to be more confident? Here are some suggestions:
Speak loudly! When you are not confident, you can’t do well what you want to do. You speak in a voice so low that other people can hardly (几乎不) hear you. Try to speak loud enough so that (以便) people can hear you clearly. The high voice can help you become more confident.
Play sports! A strong body is a strong mind. Physical exercise makes you tired but completely relaxed. A strong body helps you be full of confidence.
Encourage yourself! Write down a list of things you did during the day to see how many things you have done well. Did you finish your homework? Did you tell a joke that made everybody laugh? Give yourself praise (赞扬) for the good things you’ve done.
Pick up a hobby! If you like singing, sing as much as you can. In some ways, a hobby can make you excellent. And it will make you happy and confident.

5 . Do you know there are two kinds of football games? One is American football, the other is soccer.
In China, many young men like playing soccer. It is very popular. But the Chinese don’t call it soccer. We call it football. There are eleven players in a team. And the ball is round (圆的). Only the goalkeeper (守门员) plays he ball with his hands. The other players can’t play the ball with their hands.
In the USA, soccer is not very popular. They like playing American football more than playing soccer. There are also eleven players in a team. The ball is not round. It is oval-shaped (椭圆形的). All the players can play the ball with their hands and feet. And the goal (球门) is bigger than the goal of soccer games. American football is quite different from soccer.

| C．American football is pot round. | D．Players can use hands to play soccer. |
| A．bigger | B．smaller | C．higher | D．lower |
6 . Friends are not easy to find. True friends are harder to find. So we should do our best to make friends and keep our friendship alive (有活力的). When we are with friends, we should try to bring them closer to us. Smile is one of the easiest ways. People like to see happy faces greeting them.
When we talk to someone, ask questions to help him or her keep talking. Don’t ask questions that are too personal (私人的), or they may walk away. Another important part of communication (交流) is listening. Listen carefully to what people are saying, and respond in the right way. It doesn’t have to be with words. Body language can also show that you’re listening. It’s easier to make friends and keep friendship with people who have the same interests and hobbies as you. You can spend hours and days together, talking about your common interests. Friendship should be for life. We should try to keep friendship as long as we can.

7 . People are always trying to live a healthy life. You might have read so much on this topic (话题). The following ideas may sound strange, but they can really help you.
Exercise when you are tired.
After a long and tiring day of study, exercising may not sound like a good idea, but it should. In fact, physical activities can provide (提供) you with the missing energy. Study shows that exercising for just 30 minutes can make you feel good!
Write by hand to help the brain (大脑) be active (活跃).
Although writing something by using a computer is faster, it is much better to remember the whole thing by writing it down by hand. When you read a hand-written text, it’s easier for your brains to remember the information.
Drink hot drinks on a hot day.
What cools more on a hot summer morning, cold water or hot water? The study shows that the hot water does make people feel cooler. When you are drinking something hot, the body will feel the change in temperature and increase the perspiration (流汗), which helps you cool down!

8 . Have you ever had trouble sleeping in a new place?
Lots of people do. And now researchers (研究员) from Brown University in Rhode Island think they know why. They found that one-half of the brain “remains more awake” than the other half when people are trying to sleep in a new place.
The sleep findings were reported in Current Biology by Brown University. In their report, the researchers said many people report they have a harder time sleeping the first night at a hotel or other places outside their home. They call it “first-night influence”. “In Japan they say, ‘If you change your bed, you can’t sleep,’”said Yuka Sasaki, one of the report’s writers. “You don’t sleep very well in a new place. We all know about it.” The researchers measured (测量) brain waves for 35 volunteers for two nights in a lab. The two nights were a week apart (间隔). They found the left half of the brain was more active than the right half during the first night. This was during the first deep-sleep period, the researchers said.
Sasaki said a lot of questions remained. Researchers did not keep measuring brain waves all night long. So, they don’t know if the left half keeps “watch” all night, or whether it “works in shifts with the right half later in the night”. They also do not know why the brain activity, at least during the first period of deep sleep, is always on the left half.
1. How many times did the researchers measure brain waves for 35 volunteers?| A．Once. | B．Twice. | C．Three times. | D．Four times. |
| A．the brain waves remained the same |
| B．the brain activity helped with sleep |
| C．the right half of the brain kept“watch” |
| D．the left half of the brain was more active |
| A．Takes turns. | B．Pours out. | C．Breaks down. | D．Figures out. |
| A．What we will have to do to sleep well. |
| B．Who doesn’t sleep well in a new place. |
| C．Why it’s harder to sleep in a new place. |
| D．How researchers measure brain waves. |
9 . Happiness makes us feel good about ourselves and let everything around us look very positive (积极的). However, such feelings do not stay with us all the time. There are two important sides to be happy. One is to keep ourselves happy, and the other is to get over sadness in life.
Many people believe that money can make them happy. This is not true, because you can find many rich people who are not happy. It is true that simple things in life can make us happy. Too often, we spend too much time thinking about the future, for example, getting into college or getting a good job, so that we don’t enjoy the present. You should enjoy life’s simple pleasure, such as reading a good book, listening to your favorite music, or taking a walk in the park.
Share your life with close friends or family members. If we just focus on ourselves in life, it’s hard for us to stay happy. When we share our life with the people who are dear to us, then we grow as a human being. The support we get from friends or family members helps us stay in a health y mood.
Smile more often in life. Laughter has a magical effect on our mood. A smile can bring happiness, not only for us, but also for the people around us. A short cut to happiness in life is to smile and remain cheerful.
Being helpful makes us happy. When we help those who are not as lucky as us, we are thankful for what we have. We will see the positive side of our own life. It is believed that when we put joy into other people’s lives, the same joy will return to our life, as well.
Get over sadness. There is nothing wrong with being sad, if we know the right way to get over it. We should create a positive and calm environment around ourselves . For example, if there are people who are bothering us in our mind, we should stay away from them.
1. To be happy, ________.| A．we should keep ourselves happy | B．we should get over sadness in life | C．both A and B | D．we should get more money |
| A．One. | B．Two. | C．Four. | D．Three. |
| A．when we share our life with close friends | B．if we just focus on ourselves in life |
| C．when we help those who are not so lucky as us | D．if we smile more often in life |
| A．can help us stay in a healthy mood | B．can’t make us happy | C．has a magical effect on our mood | D．can bring happiness just for us |
| A．Being Helpful | B．Getting over Sadness | C．Smile | D．Being Happy |
10 . A fireball lit up the sky on the evening of December 15th, 2022 in Zhejiang. Instead of making wishes on this outer space object, some people were frightened, as the fireball was described as moving at a very fast speed and very bright.
The fireball was much brighter than the full moon. It was like a meteor (流星). The object was over 10 centimeters wide, and it may not burn out completely during its fall. It was time of Geminid meteor shower activity recently, so the object might come from it.
The remains of the fireball were later found in the countryside. Expert Zheng Yongchun examined the remains and said that the meteorite (陨石) has great value in studying Earth’s early history.
Scientists said that about 48. 5 tons of materials fall on Earth each day. Almost all the materials are vaporized (蒸发) in Earth’s atmosphere, leaving a bright trail called “shooting stars”. Several meteors per hour can usually be seen on any night, which are often called meteor showers.
How does a meteor land on Earth? Meteoroids (流星体), often seen as space rocks, enter Earth’s atmosphere at high speed and burn up, then meteors occur. Only 5 percent of meteorites can make it to Earth’s surface, and these can range from the size of a pebble (鹅卵石) to a fist (拳头). Even knowing the science behind this alien event, you may still worry about the chances of being hit by a meteorite. According to UK media Mirror, the chance is very small—about one in 840, 000, 000. There is only one record of a person being hit by a meteorite , which took place in 1954 in the US. The meteor crashed through the window and landed on the “lucky” lady Ann Hodges.
1. Why didn’t people make wishes when the fireball appeared? ________| A．Because it wasn’t like a meteorite. |
| B．Because it was too big. |
| C．Because it moved too fast and was too bright. |
| D．Because people didn’t like its shape. |
| A．Knock. | B．Disappear. | C．Die. | D．Appear. |
| A．It was about 2 meters long. |
| B．It was over 10 centimeters wide. |
| C．It might come from Geminid meteor shower activity. |
| D．It was much brighter than the full moon. |
| A．How the meteor comes into being. |
| B．The chances of being hit by a meteorite. |
| C．The speed of the meteor. |
| D．The events about aliens. |
| A．Where does the fireball come from? |
| B．How does a meteorite form? |
| C．Why does the meteor have a trail? |
| D．What can we see on the moon? |
