Special trees that grow faster, fight pollution, produce better wood, and even sense chemical attacks are being planted by scientists in the US.
When 40 per cent of Hawaii's US$14 million-a-year papaya (木瓜)industry was destroyed by a virus five years ago, work began on creating genetically engineered(转基因的) trees.
Researchers successfully introduced seeds that were designed to resist the virus. Since then, more and more people have been testing genetically engineered trees.
Some researchers put special bacteria into trees to help them grow faster and produce better wood. Others are trying to create trees that can clean polluted soil.
Meanwhile fruit farmers are looking for trees that are strong enough to resist worms, and paper companies want trees that produce more wood and therefore more paper.
The Pentagon (五角大楼) even gave the researchers US$500,000 this year after they developed a pine tree that changes its colours if it senses a chemical attack..
So far, the poplar, eucalyptus (杨树与桉树), apple and coffee trees are among those being engineered. All this can be done today because we have a better understanding of tree genomes(基因组).
However, some people fear that the genetically engineered trees will cause dangerous results. They are worried that the new trees will breed with natural species and change the balance of the forest environment.
"It could be destructive," said Jim Diamond, an environmentalist. "Trees are what is left of our natural environment and home to many endangered species."
But researchers insist that science could give nature a fighting chance against both natural and man-made dangers.
They hope to answer the critics by stopping the new trees from breeding, so their effect on the environment can be controlled.
What trees are NOT the ones that scientists are planting in the US?
A. Trees that worms can't hurt.
B. Trees that can protect themselves at a chemical attack.
C. Trees that can resist wind better.
D. Trees that can improve soil conditions.
What caused the American scientists to work on special trees?
A. They think science could give nature a fighting chance against both natural and man-made dangers.
B. Great numbers of trees have been lost due to attacks by viruses.
C. Researchers successfully introduced seeds designed to resist the virus.
D. Tree genomes are mapped out so scientists know how to improve trees.
Which of the following was probably the first kind of trees being engineered?
A. Papaya. B. Pine. C. Apple. D. Poplar.
The best title of the passage is .
A. The improvement of environment
B. The side-effects of special trees
C. The development of special trees
D. the program of genetically engineered trees

There is no doubt that Apple is well aware of the increased competition in the market and could be in a hurry to put another product out there, said Ramon Llamas, senior research analyst at IDC Mobile Devices Technology and Trends. Given its history with product launches and business policy, though, Apple probably isn’t going to rush an iPhone release simply to put it on shelves, he said.
“If you’re Tim Cook (CEO of Apple), you’re thinking if you want to pay more attention to how to keep growing that bottom line and keep investors(投资人) happy, or continue with the same approach from Apple, which is do what we can do and manage products and releases in the best way they can work for us. Apple usually does things in their own time, and I’m having a hard time buying this May or June timeline.” Llamas told Mac News World.
While it’s probable that Apple is surely in a testing stage for its next smartphone, consumers likely have a standard wait for the finished product, said Colin Gibbs, analyst at GigaOm Pro.
“It typically takes a year or longer to create a state-of-the-art smartphone, so no one should be surprised Apple is in the testing stages with the next iPhone. And while it’s possible that Apple could launch the next iPhone this spring or summer, I’m not expecting to see it until a little later in the year,” he told Mac News World.
When it does launch, though, it could be in a variety of colors, said Gibbs. “Apple has already tested the waters with releasing colored products when it revamped (更新,翻新)its iPod line last fall, so it is understood that it would want the new change with its smartphone, as well”.
“I wouldn’t be surprised if the new iPhone becomes available in some new colors,’’ he said. “That could be done pretty cheaply, and it would give Apple a new marketing angle.”
1.According to Ramon Llamas, Apple always ______.
A. tries to please its investors
B. rushes to put new products to market
C. ignores the fierce market competition
D. does things as planned
2.As for the next iPhone, Colin Gibbs didn’t mention ______.
A. the stage of its being tested
B. the rough time of its being released
C. the function to be improved
D. the wide variety of its color
3.What’s Colin Gibbs’ attitude towards the next iPhone?
A. Disapproving. B. Indifferent (漠不关心的). C. Doubtful. D. Objective.
4.This passage is presented in the form of ______.
A. stories B. comments C. advertisements D. debates

If the rose can be said to be a special flower, then the apple can be said to be a special fruit. It is very important in American culture. American stories speak of Johnny Appleseed, who went throughout America collecting apple seeds and planting apple trees. He had a great love for nature and went through fields and farms adding richness and beauty to the country.
One of the first sayings taught to school children is, "An apple a day keeps the doctor away." This short saying encourages children to eat fresh fruit to keep healthy. If someone always says good words to a person, people will call him an "apple polisher". This, however, is not a good name. If someone is very dear to us, we say that he or she is the "apple of our eye".
Most people believe that the fruit which Eve gave to Adam was an apple, even though the Bible(圣经) never says so. The apple, therefore, is a deep part of the language and stories of America.
An apple is also delicious. Apples can be cooked in many ways, used as a dessert (甜点) , and made into sweet juice.
In many parts of the country during the harvest season, a popular activity is to go into an apple garden to pick apples. Washington, D. C. and New York are both famous for their apples.
Finally, when it’s time to take a vacation to American cities, one can always visit New York, which is "the biggest apple" of all the American cities.
