In our life most people like green and green is an important color in nature. It is the color of most growing plants. Sometimes, the word green means young, fresh, and growing. 1..
For example, a greenhorn is someone who has no experience, who is new to a situation. In the 15th century, a greenhorn was a young cow or ox whose horns have not yet developed. 2.. By the 18th century, a greenhorn had the meaning it has today ---- a person who is new in a job.
About 100 years ago. Greenhorn was a popular expression in the American west.3.. The greenhorn lacked the skills he would need to live in the hard, rough country.
Someone who has the ability to grow plants well is said to have a green thumb. 4.
A person with green thumb seems to make the plants grow quickly and well. You might say that the woman next door had a green thumb if her garden continues to grow long after your plants have died.
Green is also used to describe the unpleasant emotion, jealousy. The green-eyed monster is not a frightening creature from outer space. It is an expression used about 400 years ago by William Shakespeare in his play “Othello”. 5. A young man may suffer from the green-eyed monster if his girlfriend begins going out with someone else. Or, that green-eyed monster may affect your friend if you get a pay raise and she does not.
A.The plants produced much larger crops.
B.The expression comes from the early 1900s.
C.Sometimes, it describes something that is not yet ripe or finished.
D.Later, it meant a soldier who had not yet had any experience in battle.
E.It was used to describe a man who had just arrived from one of the big cities.
F.It was the result of hard work by agricultural scientists who had green thumbs.
G.It describes the unpleasant feeling a person has when someone has something he wants.
Japanese researchers are genetically changing mosquitoes so that they become carriers of a vaccine (疫苗) that could vaccinate millions for free. The researchers have already genetically changed a mosquito species so that its saliva (唾液) contains a protein that acts as a vaccine against leishmaniasis(利什曼病）, a deadly disease that leads to terrible skin problems. The team confirmed that mice bitten by the genetically-engineered mosquito developed an antibody to the disease, meaning they had built up immunity (免疫力).
“You would be vaccinated without even noticing. You wouldn’t need any drug and you wouldn’t need to show up at a fixed place for mass vaccinations,” said Shigeto Yoshida, the associate professor who has led the research. “Repeated bites would only strengthen the immunity.”
Similarly the mosquitoes could be used to help treat malaria (疟疾), perhaps a decade from now, said the malaria expert.
Nearly one million people die each year from malaria ---- most of them are children ---- mainly in Africa and Asia, according to the World Health Organization. Now a problem is that no effective vaccine exists. “There is a treatment that works, but it is beyond the reach of people who need to worry about food for tomorrow,” Yoshida said.
However, Yoshida expects that the genetically-engineered mosquito will finally help wipe out the deadly disease in the developing world. “Technically speaking, I believe it’s a matter of 10 years or so, but it’s not clear whether society would accept it,” he said.
Another problem is that the genetically-engineered mosquito may still pick up and spread the infected blood of a person who has already caught malaria. Yoshida’s team is hoping it can solve this problem by developing a mosquito species that kills the malaria virus inside its own body.
1.How have scientists turned mosquitoes into carriers of a vaccine?
A. By changing their genes. B. By killing the virus in their bodies.
C. By letting them bite mice. D. By injecting vaccines into their bodies.
2.Which of the following is NOT an advantage of using mosquitoes as vaccine carriers?
A. It’s free of charge. B. It’s convenient.
C. It’s more effective. D. It’s unnoticeable.
3.What can we infer from the last two paragraphs?
A. People welcome the idea of using mosquitoes to treat malaria.
B. Mosquitoes carrying vaccines may still spread malaria.
C. It is not long before people will use mosquitoes to get rid of malaria.
D. A mosquito can kill the malaria virus inside its own body.
4.The main purpose of the passage is to .
A. introduce a possible solution to malaria
B. encourage people to use mosquitoes to fight against diseases
C. show that Japan has very advanced technology
D. call on people to help people suffering from malaria in Africa and Asia
In this world, in many cases, a lot of same things can be united together. Also, many opposite things cannot be united by many people. But there is always a chance to unite two different things in one work. The following passage will tell you more about the possibility of combining painting and poetry.
Perhaps, it is not a new idea that a great work can be created by combining paintings and poems. In this case, we can unite both things in two ways. The first way is to make the poem as the main inspiration for the painting. It is also possible to write a poem after looking at a painting.
What about the next idea to combine painting and poetry? Well, we can combine both of them on a canvas. You can paint an oil painting on it and then write down the poem on that canvas. I do not know whether this kind of idea has been used for years. But this is quite a great new idea for me. It will make more people love painting and poetry at the same time. You will not need to read the poem on plain white cloth anymore.
A poem is a good way to represent a story or a thought. It is usually not too long and not easy to be understood literally (照字面意义). It is a series of words arranged in stanza (诗节) and lines with rhyme, which are quite changeable. Therefore, combining it with another type of art (such as painting) would be very good. You can get the message of the poem through the colors on the canvas. All you need to do is to use your creativity to make a painting with the right color and with great words on it.
1.The underlined word “canvas” in Paragraph 3 probably means ____.
A. a wall of a building B. a piece of paper
C. cloth for painting D. the screen of a computer
2.What can be inferred from the passage about painting and poetry?
A. Painting and poetry are so alike that they can be united.
B. Poetry can inspire us to paint and the opposite is also true.
C. Painting and poetry have been recently combined together.
D. The author created the idea of combining painting and poetry.
3.According to the passage, a poem usually has all of the following features EXCEPT ________.
A. not being too long B. being representative
C. having deep meanings D. having fixed forms
We are busy talking about and using the Internet, but how many of us know the history of the Internet?
Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer network didn’t work well. If one computer in the network broke down, then the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way computer network system would keep on working on the time.
At first the Internet was only used by the government, but in the early 1970s, universities, hospitals and banks were allowed to use it too. However, computers were still very expensive and the Internet was difficult to use. By the start of the 1990s, computers became cheaper and easier to use. Scientists had also developed software that made “surfing” in the Internet more convenient.
Today it is easy to get on-line and it is said that millions of people use the Internet every day. Sending e-mail is more and more popular among students.
The Internet has now become one of the most important parts of people’s life.
1.A new network system was set up to _________.
A. make computers cheaper
B. make itself keep on working all the time
C. break down the whole network
D. make computers large and expensive
2.__________ made “surfing” the Internet more convenient.
A. Computers B. Hardware
C. Software D. Information
3.Which of the following is TRUE?
A. In the 1960s, computer network worked well.
B. In the early 1970s, the Internet was easy to use.
C. Today it’s still not easy to get on-line.
D. Sending e-mail is now more popular among students than before.

Smart phones had become part of our daily life. No matter who we are, we can see people busy play with their smart phones. Smart phones benefit them. They help us escape the pressure of life and get informations. However, if we spend too much time on them, we won’t have time to contact face to face our friends or family. And our life, study and work will hurt. In my view, we should limit to our using smart phones except for a purpose of learning. Meanwhile, it’s absolute necessary for us to take part in more outdoors activities.
