短文改错
Last Saturday our class went hiking in a countryside. We meet at our school gate and set off at 8:00 am. On the way, we were singing and laughing happily while a girl suddenly fell into a deep hole.She felt so frightening and even burst into tears. One of my classmate found a long rope and we got him out. Fortunately, she didn’t suffer seriously injuries, but it seemed that her ankle slightly twisted. We managed to sending her to the nearest hospital. It is an experience we’ll never forget it, though we didn’t enjoy ourselves very much that day.
阅读下面材料，在空白处填入适当的内容（1个单词）或括号内单词的正确形式。
Steam trains were replaced by electric ones many years ago, so when the newspaper I worked for 1. (hear) that the Admiral steam engine had been restored (恢复), they decided to send me on 2. (it) first trip. I wanted to go even though I 3.(general) disliked travelling by train. In fact, I was looking forward to 4. (see) something I had never seen before.
When I arrived at the station, lots of people had already been there for a while, enjoying the 5. (celebrate) of the rebirth of the Admiral. At two o’clock, everyone was ready 6. (board) the train. I settled myself into a compartment (列车车厢) where I was soon joined by an old man 7. claimed to be one of the original workers on the Admiral. He told me how much he had hated being covered in coal dust all 8. time. His family had been too poor to buy more things 9. the basic necessities. It was a pleasure to listen to him. At every station, people were waiting to greet the train, and it was 10.(excite) to see their faces as the past seemed to come alive again.
She wasn’t aiming to make history. But in the late 1990s, when Sumita Mitra, a chemist at 3M, _____ to use nanotechnology(纳米技术) to improve dental (牙齿的) fillings, that’s exactly what happened. Now _____in dental offices--- and almost every mouth, her fillings are certainly one of the life-changing _____.
Any invention starts with a _____ and so did Mitra’s fillings. Before the mid-1990s, fillings came in two different _____. One wasn’t strong enough for stress-bearing _____ of the teeth like biting surfaces, and the other was strong but could become rough from _____ and chewing. Dentists often had to use two types of materials for every filling, which _____ problems.
In the 1990s, nanotechnology became a growing field for scientific advances. Mitra thought that _____ nanoparticles(纳米粒子) could be used to make a filling, the result would both look nice and be able to _____ wear and tear. Mitra didn’t have much _____ with nanotechnology, but scientists at 3M’s research labs were _____ with it for other uses. She joined them and _____ some very unique combinations of nanoparticles. Realizing that nanoparticles could _____ all the requirements was one significant moment, but the _____to combine nanoparticles was the big breakthrough. Nanoparticles are all the same size, and Mitra realized that she could _____them like a bunch of grapes. The work was groundbreaking and _____ the creation of a famous product--- the 3M Filtek Supreme Universal Restorative. The product was the first successful _____of nanotechnology in dental material and the first commercial application of nanotechnology at 3M.

Happiness doesn’t mean being joyful or laughing all day long. Although happiness should be defined by each of us for ourselves, a general understanding of it could be having more good moments and memories than bad ones and having an overall feelings of satisfaction and fulfillment. 1. Read on and you will know the answer.
*2.Many of us have the impression that we’re not allowed to be happy and that we don’t deserve it. Well, we all deserve to be happy, no matter what others say or even what we believe. So allow yourself to be happy.
*Smile even if you don’t feel like it. Yes, smile as often as you can. 3.If you’re alone, smile for at least 3 minutes and our brain will take it as a real smile and will start producing feel-good hormones(荷尔蒙) and other chemicals.
*Enjoy the now. 4.Worrying about the future will not make you any more ready for whatever it is that finally happens. Choose the now and make an effort to live it.
*Count your blessings. Take a piece of paper and something you like to drink and sit comfortably maybe with some nice music in the background. Then write a list of every blessing in your life. Start with the smallest ones: I’m alive... to the biggest ones you can feel. 5. Once you’re done, leave the list on the table. Read it every morning during breakfast for a week.

E.So, how can we have more happy moments?

Floating on the surface of the seas of the world are billions of tons of small plants and animals called plankton. Most of these plants and animals are too small for the human eye to see. They move about lazily with the currents, providing a basic food for many larger animals. Plankton has been described as the equivalent (相等的东西) of the grasses that grow on dry land, and the comparison is an appropriate one. In potential food value, however, plankton far outweighs that of land grasses. One scientist has estimated that while grasses of the world produce about 49 billion tons of valuable carbohydrates(碳水化合物) each year, the sea’s plankton produces more than twice as much.
Despite its enormous food potential, little effort was made until recently to farm plankton as we farm grasses on land. Now scientists have at last begun to study this possibility, especially as the sea’s resources appear even more important as a means of feeding an expanding world population.
No one yet has seriously suggested that “planktonburgers” may soon become popular around the world. As a possible farmed supplementary food source, however, plankton is gaining considerable interest among scientists.
One type of plankton that seems to have great harvest possibilities is a tiny creature called krill(磷虾). Growing to two or three inches long, krill are a major food source for the giant blue whale, the largest animal ever to live on the Earth. Realizing that this whale may grow 100 feet and weigh about 150 tons, it is not surprising that each one swallows more than one ton of krill daily.
Krill swim about just below the surface in huge schools sometimes wide, mainly in the cold Antarctic. Because of their pink color, they often appear as an entire reddish mass when viewed from a ship or from the air. Krill are very high in food value. If krill can feed such huge creatures as whales, many scientists reason, they must certainly be competitors among possible new food sources for humans.
1.Which of the following correctly describes plankton?
A. It has a higher food value than grasses. B. It is food for most small sea animals.
C. It can grow on dry land as well. D. It grows up in the deep water.
2.Why does the author mention”planktonburgers” in Paragraph 3?
A. To show scientists’ interest in plankton.
B. To describe the appearance of plankton.
C. To question the food potential of plankton.
D. To suggest plankton as a possible food source.
3.According to Paragraph 4, the blue whale___________.
A. feeds mainly on krill. B. can grow up to 150 feet.
C. suffers from lack of food. D. was born two or three inches long.
4.Which of the following is TURE about krill?
A. They mainly live in the Arcitc. B. They are of great value to humans.
C. They are the smallest sea animals. D. They come in many different colors.
