1 . Ten years ago, I set out to study luck. I wanted to know why some people are always in the right place at the right time, while others always experience ill luck.
Many people volunteered for my research. Over the years I interviewed them, watched their lives and had them take part in my experiments.
I carried out a simple experiment to discover why there were differences in their ability to spot (发现) opportunities. I gave both lucky and unlucky people a newspaper and asked them to look through it and tell me how many photos were inside.
I had secretly placed a large message halfway through the newspaper saying, “Tell the researcher you have seen this and win $50.” This message took up half of the page and was more than two inches high. It was staring everyone straight in the face, but unlucky people tended to (倾向) miss it and lucky people tended to spot it.
Unlucky people are just more nervous than lucky people. They are busy looking only for what they need and this stops them from noticing the unexpected. As a result, they miss out on opportunities.
Lucky people tend to be more relaxed and open. They can see everything that is in front of them, rather than just what they are looking for.
My research shows that lucky people live by several principles (原则). Here are some of these principles: Listen to your gut instincts (直觉)—they are often right. Be open to new experiences and break your normal thought patterns. Spend a few moments each day remembering things that went well. See yourself being lucky before an important meeting or phone call.

In many countries, people are encouraged to buy electric cars. It is said that driving an electric car is good for the environment. But is that true? The University of Minnesota recently studied emissions (排放物) from different cars. The scientists found that sometimes, electric cars are more harmful than petrol (汽油) cars.
Surprising? Well, please pay attention to the word “sometimes”. Electric cars are supposed to be clean. The problem lies in the power that is used to charge them. If the power comes from wind or solar energy, electric cars will cause little pollution. However, if the power is produced from coal, they will be very harmful. According to the study, emissions from these cars kill about 3,000 people a year. However, pollution caused by petrol cars only leads to 880 deaths a year.
In fact, sales people are not lying when they say electric cars are clean. However, they are right only when the power used to charge their cars is also clean.
So how clean electric cars are depends on what its electricity comes from. In France, more than half of the power comes from nuclear (核) stations. Electric cars there should be as clean as they are marketed to be. In many developing countries, however, electricity mainly comes from coal. India, for example, depends on coal for 61 percent of its power. Only two percent of electricity comes from nuclear energy. In countries like India electric cars are not clean at all.
1. Why are people in many countries encouraged to buy electric cars? Because they think electric cars2. How are electric cars whose power come from wind or solar energy?
If the power of electric cars comes from wind or solar energy, it will cause
3. How many people may be killed a year by the emissions from the cars whose power is produced by coal?
Emissions from the cars whose power is produced by coal can kill about
4. According to the passage, in which country the electric cars are cleaner than many developing countries?
Electric cars from
5. Where may power of electric cars come from? (至少写出文中提到的两种能源)
3 . Oil becomes more expensive and difficult to find. It’s becoming less and less, too. Scientists are looking for other energies, including solar (太阳能), wind and even nuclear (核能) power.
Solar boards (板) catch energy from the sun and turn it into electricity. One of the world’s largest solar power stations is in Germany. What’s more, solar energy produces no waste.
Wind, the fastest growing kind of energy, is another way of collecting energy from the sun. As we all know, Holland is famous for its wind electricity. And it’s also called Windmill Kingdom (风车之国).
Nuclear power produces electricity more cheaply with no carbon (碳) waste. And more countries join the nuclear group. China has built twenty-two nuclear power stations, too.
1. Which is NOT the reason for scientists to look for other energies?| A．Oil becomes more expensive. | B．There is less oil. |
| C．People don’t like using oil. | D．It’s difficult to find oil. |
| A．From the earth. | B．From the sun. | C．From the moon. | D．From the stars. |
| A．Germany | B．China | C．America | D．Holland |
| A．Solar. | B．Wind. | C．Ocean. | D．Nuclear. |
| A．Germany has one of the world’s largest solar power stations. |
| B．Nuclear power produces more carbon waste. |

4 . Each year, hundreds of people climb Mount Qomolangma. Most of them do it to achieve a personal dream. But for some, they push themselves up the mountain for other purposes.
On September 24, 2021, Guo Yongjie and the other seven members of a team set out at a height of 5,800 meters. They reached a height of around 6, 200 meters several hours later. This was the second time the Chinese team had climbed Mount Qomolangma in 2021, following their first trip in August.
“Desideria himalayensis,” Guo cried as soon as he saw a plant. He took pictures of the plant from all directions and recorded its height and location right away. It was the first plant they found at a height above 6,000 meters. What made Guo more excited was that some of the siliques (角果) of the plant had divided, which meant the team had a chance to collect its seeds (种子).
To do research, a complete seed sample (样本) needs at least 2,500 seeds. However, since seeds are scarce at high points of Mount Qomolangma, it is hard to collect 2,500 seeds. So the team could only try to collect as many as possible.
In July 2022, after being kept in very low temperatures for nearly a year, the seeds collected on Mount Qomolangina were taken out to test if they were alive. And soon all the seeds germinated (发芽). It means that China has successfully collected and kept those valuable seeds.
A seed carries the hope of life from the moment it comes into being. For China, those seeds have brought more hope to its plant protection.

5 . Blood transfusions（输血）have become a real life saver in modern medicine. But not so long ago, blood transfusions were dangerous and killed as many people as they saved. That is, until 1901, when an Austrian scientist discovered that humans do not all have the same blood type. His research showed that humans, in fact, have one of four blood types A, B, AB and O.
Before the discovery of the four blood types, it was believed that you could give the blood of any person to any other person. Giving a person the wrong type of blood often leads to death because the two different blood types fight each other. When giving a blood transfusion, doctors need to know the blood types of the donor（输血者）and the recipient（受血者）.
No matter where you live on this planet, your blood will fall into one of the four types. Some blood types are rarer than others. In European cultures, the most common blood type is O. Among Asian populations, the B blood type is common, while it is very rare in European populations.
People with type O blood are “universal（万能的）donors”. Their blood can be given safely to people from any of the other three groups. People with type AB blood are “universal recipients”. They can receive blood from any of the other three groups.
1. Why is blood transfusion dangerous before the discovery of the four blood types? ________| A．Because two different blood types fight each other. |
| B．Because there is no modern medicine. |
| C．Because there are fewer blood donors. |
| D．Because people are from different cultures. |
| A．the O blood type | B．our planet |
| C．B blood type | D．the most common blood type |
| A．Because the type O blood is the most common. |
| B．Because the type O blood is rare. |
| C．Because people with type O blood are kind and friendly. |
| D．Because the people of the other three groups can receive type O blood safely. |
| A．The blood transfusion is always safe. |
| B．In 1901, an Austrian scientist discovered the four blood types. |
| C．Doctors don’t need to know the blood type before a blood transfusion. |
| D．People could receive blood from any person. |
| A．Blood transfusions are dangerous. |

7 . “Early to bed and early to rise makes a man healthy, wealthy and wise!” This is an old English saying. It means that when we go to bed early, we can get up early the next morning. Then we will become healthy, rich and clever.
