Boyan Slat has been dreaming of cleaning up the world's oceans for a long time.
In 2010，he went on a diving （潜水）vacation in Greece and was shocked."I saw more plastic bags than fish in the water，" he said.
From then on，Slat began to pay more attention to ocean pollution.He decided to give up higher education and set up the Ocean Cleanup，a non﹣government organization.Its purpose is to clean up ocean rubbish.He has set up the world's first ocean cleanup system （ 系统）with his team.
Every year，over 8 million tons of plastic end up in our oceans，and it can take up to 500 years to break down.In 2018，the World Economic Forum predicted that the weight of ocean plastic would match that of all the fish in our oceans by 2050.Sea animals easily get caught in plastic.They can't move.They can even die if they eat it.Smaller plastic pieces can also enter the food chain （链）and end up in our bodies.
Slat's plan was to create an environmentally﹣friendly，large system to clear out plastic rubbish from the ocean.
After seven years of tests，on October 2nd，2019，a machine called System 001/B came out.It successfully caught and collected a large amount of plastic rubbish floating in the ocean.
Slat and his team are working to improve System 001/B.Their dream is to clear out 90 percent of all the ocean plastic by 2040.

There have been many great inventions or things that changed the way we live. The first great invention was the one that is still very important today——the wheel. This made it easier to carry heavy things and to travel long distance.
For hundreds of years after that there were few inventions that as much effect as the wheel . Then in the early 1800s the world started to change. There was little unknown land left in the world. People didn’t have to explore much any more. They began to work instead to make life better.
In the second half of the 19th century many great inventions were made. Among them were the camera, the light and the radio. These all play a big part in our daily life today.
The first part of the 20th century saw more great inventions. The helicopter in 1909, movies with sound in 1926, the computer in 1928, jet planes in 1930. This was also a time when a new material was first made. Nylon came out in 1935. It changed the kind of clothes people wore.
The middle part of the 20th century brought new ways to help people get over diseases. They worked very well. They made people healthier and allowed them to live longer. By the 1960s most people could expect to live to be at least 60.
By this time most people in developed countries had a very good life. Of course new inventions continued to be made. But man now had a desire(渴望) to explore again. The earth was known to man but the stars were not. Man began looking for ways to go into space. Russia made the first step. Then United States took a step. Since then other countries , including China and Japan, have made their own steps into space.
In 1969 man took his biggest step away from earth. Americans first walked on the moon. This is certainly just a beginning, though. New inventions will some day allow us to do things we have never yet dreamed of.This passage talks mainly about .
| A．why cars were very important |

Because earthquakes happen without warning, it’s important to take steps now to prepare. Because you don’t know where you will be when an earthquake happens, prepare some supplies for your home, workplace, and car.
1. Water.
A person needs at least 1/2 gallon of water daily just for drinking. Store at least 1 gallon of water per person per day and be prepared for a 72-hour period. It is suggested that you buy bottled water. Keep bottled water in its original container and do not open it until you need to use it. Also, do check the “use by” date.
2. Food.
It’s always a practical idea to keep a supply of non-perishable(不易腐烂的) food on hand. Have an enough supply of canned food, powdered milk, dried fruits, non-salted nuts and canned juices for at least 72 hours.
3. Flashlights(手电筒) and spare batteries.
Keep a flashlight beside your bed, at your place of work, and in your car. Do not use matches or candles after an earthquake until you are sure that no gas leaks.
Prepare a battery-powered radio and spare batteries. Most telephones will be out of order, so radios will be your best source of information.
4. Clothes.
If you live in a cold place, you must think about warmth. You might not have heat after an earthquake. Think about your clothing and bedding supplies.Why should people prepare themselves for an earthquake?
| A．Because earthquakes can be known before they happen. |
| B．Because earthquakes take place without warning. |
| C．Because earthquakes usually take place in the neighborhood. |
| D．Because it’s people’s daily work to prepare the earthquakes. |

Whenever the sun dropped and the blue sky came up, my father and I used to climb the mountain near my house. Walking together, my father and I used to have a lot of conversations through which I learned lessons from his experiences. He always told me, “You should have goals like climbing the mountain.” Without the mountain-climbing that we both enjoyed, we couldn’t have enough time to spend together because my father was very busy. I really got a lot from the mountain-climbing. It gave me time to talk with my father and to be in deep thought as well as develop my patience.
Once we climbed a very high mountain. It was so challenging for me because I was only ten years old. During the first few hours of climbing, I enjoyed the flowers and trees, and the birds’ singing. But as time passed, I got a pain in both of my legs. I wanted to quit climbing, but my father said to me, “You can always see a beautiful sky at the top of the mountain, but you can’t see it before you reach the top. Only there can you see all of the nice things, which is just like your life.”
At that time, I was too young to understand his words. But later after that, I got to know the meaning of hope in life. I found myself standing at the top of the mountain, and the sky was as clear as crystal.The passage tells us that mountain-climbing was ______ for the father and the son.

What might the future be like? Here are some predictions: things to come, things to go.
The Spring Festival, the most important Chinese holiday when everyone returns home, has caused headaches for millions of Chinese. More than 2 billion people travel at the same time, making getting travel tickets and the journey difficult. But in 28 years, Spring Festival travel may not be a problem at all. China plans to build more than 120,000 kilometers of railway and a fast transportation network that will serve 90% of the population by 2020. And because most of China will be cities, people will not have to go to other places to find a job, so it will no longer be a problem.
Newspaper will come to an end in 2043. In the future, digital(数字的) newspapers will be sent to personal web tools through Internet. Readers can discuss topics with journalists and editors. Information will move faster.
Oil is running out faster than expected. But scientists have found something else for oil as fuel(燃料). Coal, natural gas, solar power, nuclear power and even water can take the place of oil as sources of energy(能源).
Schools will go electronic(电子化). Computers will be important and popular among the students. Everything will be in the computer and students will not need to bring books to school. They will find information on the Internet. A computer will be the students’ library, schoolbag and connection to the outside world.
