Bamboo is one of the nature’s most surprising plants. Many people call this plant a tree, but it is a kind of grass.
Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. A Japanese scientist recorded one bamboo plant that grew almost 1.5 meters in 24 hours! Bamboo grows almost everywhere in the world except Europe. There are more than 1,000 kinds of bamboo that grow around the world on both mountains and plains.
Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimeters wide while others may grow to more than 30 centimeters across. This plant also comes in different colors, from yellow to black to green.
Many Asian countries have been using bamboo for hundreds of years. They often use bamboo for building new buildings. As a matter of fact, the cables(绳索) that hold up the hanging bridge across the Min River in Sichuan are made of bamboo. The bridge has been in use for more than 1,000 years, and is still holding strong.
In Africa, engineers are teaching poor farmers how to find water using bamboo. These African countries need cheap ways to find water because they have no money, and their fields often die from no rain and no water. It seems that bamboo is one of the best things they can use. Bamboo pipes and drills(钻) can help to make the poor thirsty fields to be watered.How is bamboo like grass?
| A．It is thin and easy to cut. | B．It grows everywhere. |

In a world with limited land, water and other natural resources(资源), the harm from the traditional business model is on the rise. Actually, the past decade has seen more and more forests disappearing and the globe becoming increasingly warm. People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable(可持续的)ways. That means growth with low carbon or development of sustainable products. In other words, we should keep the healthy while using its supply of natural resources.
Today, sustainable development is a popular trend in many countries. According to a recent study, the global market for low-carbon energy will become three times bigger over the next decade. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy resolution. It is now trying hard to made full use of wind and solar energy, and is spending a huge amount of money making electric cars and high-speed trains. In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil(棕榈油), which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown more than 50%.
Governments can fully develop the potential of these new markets. First, they can set high targets for reducing carbon emissions(排放) and targets for saving and reusing energy. Besides, stronger arrangement of public resources like forests can also help to speed up the development. Finally, governments can avoid the huge public expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate the change from the traditional model to a sustainable one.
The major challenge of this century is to find ways to meet the needs of a growing population within the limits of this single planet. That is no small task, but it offers a large of new chances for sustainable product industries.The traditional business model is harmful because of all the following EXCEPT that____.
| A．it makes the world warmer |
| B．it consumes natural resources |
| C．it brings severe damage to future |
| D．it makes growth hard to continue |
What can we infer from Paragraph2?
| A．China lacks wind and solar energy |
| B．China is the leader of the low-carbon market |
| C．High-speed trains are a low-carbon development |
| D．Palm oil is made at the cost of valuable forests |
To fully develop the low-carbon markets, governments can______.
| A．cut public expenses | B．forbid carbon emission |
| C．develop public resources | D．encourage energy conservation |
We can learn from the last paragraph that business have many chances to _______.
| A．develop sustainable products | B．explore new natural resources |
| C．make full use of natural resources | D．deal with the major challenge |
What is the main purpose of the passage?
| A．To introduce a new business model | B．To compare two business models |
| C．To predict a change of the global markets | D．To advocate sustainable development |
Bad teeth can be painful — and worse. They can even be deadly. Infections (感染）of the gums (牙龈）and the teeth can cause bacteria (细菌）to go into the blood system. Those bacteria can increase the chance of a heart attack and worsen the effects of other diseases. And adults are not the only ones at risk. For example, in 2007, doctors in the Washington area said a boy died when a tooth infection spread to his brain. They said it might have been prevented had he received the dental care (牙齿 保健）he needed. He was twelve years old.
Experts at the National Institutes of Health say good dental care starts at birth. Breast milk, they say, is the best food for the healthy development of teeth. Breast milk can help slow the growth of bacteria and acid production in the mouth.
But dentists say a baby's gums and early teeth should be cleaned after each feeding. Use a cloth with a little warm water. Do the same if a baby is fed with a bottle. Experts say if you decide to put your baby to sleep with a bottle, only give the child water.
When baby teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently.
The use of fluoride (氟化物）to protect teeth is common in many parts of the world. For example, it is often added to drinking water supplies. The fluoride mixes with enamel (法琅质)， the hard surface on teeth, to help prevent holes from forming.

I’ve loved my mother’s desk since I was just tall enough to see above the top of it as mother sat doing letters. Standing by her chair, looking at the ink bottle, pens and white paper, I decided that the act of writing must be the most wonderful thing in the world.
Years later, during her final illness, mother kept different things for my sister and brother. “But the desk,” she said again, “is for Elizabeth.”
I never saw her angry, never saw her cry. I knew she loved me; she showed it in action. But as a young girl, I wanted heart-to-heart talks between mother and daughter.
They never happened. And a gulf opened between us. I was “too emotional (易动感情的)”. But she lived “on the surface”.
As years passed and I had my own family. I loved my mother and thanked her for our happy family. I wrote to her in careful words and asked her to let me know in any way she chose that she did forgive me.
I posted the letter and waited for her answer, none came.
My hope turned to disappointment, then little interest and, finally, peace it seemed that nothing happened. I couldn’t be sure that the letter had even got to Mother. I only knew that I had written it, and I could stop trying to make her into someone she was not.
Now the present of her desk told me, as she’d never been able to, that she was pleased that writing was my chosen work. I cleaned the desk carefully and found some papers inside — a photo of my father and a one-page letter, folded (折叠) and refolded many times.

Bicycles are a great way to get around. They’re fun to ride, especially down hills. And, as you speed along the road, you might also think of ways in which you could improve your bike— make it safer, more efficient, or more comfortable. In fact, the two-wheeled machines make for some cool science projects.
This year's Intel International Science and Engineering Fair (ISEF), held last May in Cleveland, featured（had）three bicycle projects from three countries. Like many of the other experiments presented at ISEF, the bike projects showed that some of the most interesting scientific research often begins by taking a closer look at things you care about.
Renato Angulo Chu had even grander ambitions. The 12th-grader from Lima, Peru, wanted to address some of his country's economic troubles.
"I see a problem in my country," Renato said. "If you go to the forests in Peru, in some places you cannot find electricity. If you go with my bicycle, you can turn on the lights."
Renato, 16, spent 3 years designing his special Multibike. The device looks like a fixed exercise bike. It has wires fixed along the frame and a blender strapped (fastened) to the back. Turning the pedals operates the blender. The same principle can be used to sharpen knives or sweep city streets.
The Multibike can work either as a fixed bike or as a bicycle able to travel city streets and country roads. It's made from inexpensive materials, and the user gets exercise while pedaling to operate a machine.
"You pedal the bike, and you can mix any drink you want," Renato said. More importantly, he added, the same concept could be used to bring light to houses in remote regions of the rainforest. What can we learn from the first paragraph?
| A．Bikes should be made more comfortable to ride. |
| B．You can improve your bicycle for science research. |
| C．Many inventions are connected with the bicycle. |
| D．Bicycles are the best way to go about |
Which of the following is true according to the passage?
| A．ISEF is an exhibiton displaying bicycle experiments designed by students. |
| B．Looking closely at things you are concerned about can lead to scientific research. |
| C．Renato’s improvement of the bicycle has solved the country’s great problem. |
| D．Renato’s special bicycle will soon be put into use in remote areas.’ |
The underlined word “address” in the third paragraph probably has the same meaning as _______.
| A．make address written | B．give up | C．work at | D．speak at |
Renato’s special Multibike has all the following EXCEPT ________.
| A．making knives sharp | B．mixing any kind of drinks |
| C．producing electricity | D．operating a machine with its own electricity |
It can be inferred that Renato’s special bicycle is mainly designed for ________.
| A．distant areas in the rainforest without electricity. |
| B．the use of his own family to make life easier. |
| C．the competition of ISEF to win money to support remote rainforests |
| D．enough exercise by pedaling it |
