Forest are amazing and so are the animals that live in them. We enjoy watching TV shows about bears, bats or monkeys. We know a lot about their lives: how they find food or what they do at different times of the year. But what about smaller animals that are more difficult to see or film?
Many small animals that live in forests are very important for the soil. A French scientist, Francois Xavier Joly, is studying one of them — the millipede(千足虫).
The importance of leaves
When the leaves begin to die in fall, they turn from green to yellow and fall from the trees. As they decompose on the ground, nutrients(营养物质) are returned to the soil and carbon dioxide to the air. Life in the forest needs these nutrients. Without them, plants could not grow and there would be no food for animals such as the millipede.
Food on the forest floor
Some living things, like mushrooms, break the leaves into smaller pieces and eat them. In a few months there is nothing left of them. But for mushrooms, not all trees are the same. Mushrooms prefer some types of leaves to others. This means that some leaves take much longer to be broken down than others. Sometimes it takes years. So what happens to these? This is where the millipede can help.
More on the menu
The millipede also likes leaves and it eats any type. But when it has finished, it produces waste. This waste then becomes the food of mushrooms. When mushrooms eat leaves they choose only certain types but when they eat waste, they will eat any kind. This is how the millipede turns dead leaves into food for others and helps life continue.
So next time you are walking through a forest, remember that something may be having a meal right under your feet.
1.According to the passage, what can we learn about the millipede?
A. It can often be seen on TV shows.
B. It mostly feeds on the nutrients in the soil.
C. It is too small to be noticed by people.
D. It lives under mushrooms in the forest.
2.What does the underlined word "decompose" in Paragraph 3 mean?
A. Break down.
B. Dry up.
C. Dig in.
D. Make out.
3.What does the author want to tell us by mentioning mushrooms?
A. The millipede eats mushrooms in the forest.
B. The millipede helps to provide food for mushrooms.
C. Mushrooms play an important part in helping millipedes out.
D. Mushrooms decide what types of leaves the millipede will eat.
4.According to the author, the millipede is ________.
A. poisonous
B. rare
C. unimportant
D. amazing

Some of the planet’s most precious animals and plants are disappearing, according to the World Conservation Union (IUCN). The group, based in Switzerland, works with governments and experts to protect threatened species. On September 12, the IUCN released its Red List, a list of species at greatest risk of extinction.
The list includes 41,415 animals and plants. The IUCN says that habitat destruction, hunting and other causes threaten one in four mammals, one in eight birds and one in three amphibians(两栖动物).
Who is to blame?
Scientists believe that 99 percent of threatened species are at risk because of human activity. “We are losing animals and plants at a high rate,” says Julia Marton-LefEevre, director general of the IUCN. “We need to change our behavior.” Warmer oceans and over-fishing are changing sea life. This year for the first time corals(珊瑚) made their appearance on the list. The gharial, a crocodile living in India and Nepal, has lost almost 60 percent of its population in the last 10 years. It is a victim（受害者）of habitat destruction.
Still, the news is not all bad. Thanks to efforts made to protect it, the Mauritius echo parakeet, a bird once endangered, has seen an increase in its population. “This shows that protection methods can work,” says Marton-LefEevre. “That’s the message we want to send to young people.”
In China the new reserve（保护区）itself is part of green efforts that have seen more than 2,400 nature reserves of various kinds being set up, covering more than 15 percent of the nation's land area, official figures showed.
"The country's natural resources(资源) have benefited from conservation," said Lei Guangchun, director of the nature reserve department of Beijing Forestry University. "It is a big increase nowadays compared with other countries." Lei said.
The total areas of China’s natural reserves have covered 1.38 million km2, which accounts for 15.4% of China’s area, higher than both the world average（平均水平） of 11% and the rate in most developed countries.
Li Zhong, an official in charge of the nature reserves office with the State Forestry Administration, thought it was important to increase investment（投资） in such reserves at all levels.
1.What do we know about the IUCN?
A. A union for listing animals and plants on the earth
B. A group of volunteers who are interested in wildlife
C. An organization concerning the protection of rare species' survival
D. A government made up officials, scientists and experts
2.What can be concluded from the passage?
A. All the protection methods can’t work.
B. The IUCN does most of the protection.
C. The efforts China makes has paid off.
D. Enough is done in wildlife protection.
3. Which of the following is not the cause of the disappearance of the animals?
A. Bad weather B. Over-hunting C. Warmer oceans D. Habitat destruction
4.Which of the sentence is NOT true?
A. China has been paying great attention to protecting the natural resources.
B. China has set up a lot of natural reserves.
C. The natural reserves in China cover more than 15 percent of the nation's land area.
D. The rate of China's natural reserves is lower than the average of the world.

"If popular culture has taught us anything, it is that someday mankind must face and destroy the growing harm caused by robots." Author Daniel Wilson's description of How to Survive a Robot Uprising seems like it is straight out of a robot disaster movie. "The problem with cleverly-designed robots is that we become dependent on them," says Wilson.
The classic movie Westworld describes an amusement park where, after a safety error, the robots spend a killing period of time. Yet in reality, statistics show that as technology improves there is a trend towards increased safety. Similarly, public transport systems using computers and machines are believed to be more reliable than those in human control, and a robot-assisted operation is more precise and results in fewer medical problems.
But where does the idea of robots being cruel and harmful come from? "Robots were pop culture figures before they existed," says Wilson. "They were frightening creatures in novels. When robots really started existing, they already had this image(形象) set up not based on reality. That's exactly what happened—a movie monster became real."
Recent reports talked of a robot "attack" on a worker in Sweden. Even if these references to an attack rather than an error are meant in joke, this only makes the problem worse. "We're so interested in the robot-attack storyline that it can influence the way real robot-safety problems are discussed," says one journalist. But with robots becoming increasingly advanced, is it going to come a time when an error could become an unkind and cruel attack?
"Robots are just a bunch of metal," says one engineer. "If you are scared, then you are scared of the people building them." So what do engineers think we should be afraid of? Nanotechnology is the science which involves developing and making extremely small but very powerful machines. Some engineers suggest that with these new developments come "severe dangers" if they are used inappropriately. Its theory goes that "the small size and rapid potential of nano-built weaponry（武器）will make it difficult to control and hard to keep out of the hands of terrorists. "And this is a view shared by some artificial intelligence experts. "With robots...if it makes an error, you can unplug it and shut it down. But if you have lots of nano-built weapons, which are extremely small, there is no way you can do the same thing."
1.In the first paragraph, Daniel Wilson ________.
A. confirms the existence of robots
B. introduces the development of robots
C. states that robots are potentially dangerous
D. suggests that we should be dependent on robots
2.People have come to think of robots as something bad because ________.
A. designers of the first robots spread this idea
B. reality shows they are the same as in the movies
C. movie audience continue to give this impression
D. they were originally described this way in novels
3.The author believes that the report of the robot attack in Sweden ________.
A. is intended as a joke
B. serves as a serious warning
C. presents the technical problem
D. expresses sympathy for the worker
4.What are experts afraid of when considering nanotechnology?
A. Robots could use it inappropriately.
B. It could make robots harder to control.
C. It could be more dangerous than robots.
D. There'll be more terrorist attacks because of it.
