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(千足蟲).

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(營(yíng)養(yǎng)物質(zhì)) 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

I'd like to talking about my most memorable experience. It was the trip to Australia I had three years before with my dance group to participate in international dance festival. It was the first time that I had travelled by plane in my life. My mum worried a lot, so everything went smoothly. I stayed there for two week and it was the happiest time in my life. Besides our performances there, we have much excitement. We spent on almost every morning sunbathing on the beautiful beach and swam in the blue sea. But warmly Australian nights were which I adored most of all. It was a time of joy, lights, music and summer parties.

My son ,Izzy, was a nine-year-old boy and had been begging me to please let him find his way home by subway, by himself. After all, we live in New York City, and getting around by public transportation is a basic part of life. It is also the first step toward feeling grown-up. So on that sunny Sunday，I gave him a subway map, a transportation card,$20 for emergencies, and a couple of coins so that he could call me if necessary. I didn’t give him a cell phone because nine-year-olds lose things. A few days later, I wrote about his adventure，or non-adventure for a newspaper. Little did I realize the idea that a kid could tour the city on his own, and that a mom would let him, was big news. It turned out that many TV shows called me and asked for an interview. Bloggers were going crazy, so I started a blog, too, and letters came pouring in. Finally I found out why this was such a big story: we have become fearful for our children. Fear is hardly a new thing for parents, of course. But the fear of letting our children out of sight for even a second-that’s new. How did this happen? How did it become too scary to let kids be kids? I asked the question when the reporter Trevor Butterworth interviewed me.

“News reports,” he answered. “News reports scare the pants off you. What is scarier than a kidnapped kid no matter how far away？Because there are so many such stories, it starts to feel as if kidnappings are happening all the time. That’s why the kid-on-the-subway story surprises the whole world.” Izzy probably did a good job. He simply proved that kids could leave home alone and return home safely! But he didn’t think it was a big deal. “It was fun,” he said. “But I missed some classes because of the interviews.” Sometimes it really pays to be brave.

1.Why did the author let her son take the subway alone?

A. Because she always let her son do whatever he wanted.

B. Because she believed that her son had memorized the subway map.

C. Because she thought it would be big news around the whole world.

D. Because she felt traveling by subway in New York was a basic life skill.

2.The author gave her son all the following when he traveled alone EXCEPT_______.

A. a map. B. a cell phone.

C. a transportation card D. some money.

3.The author didn’t expect that after she wrote her son’s story for a newspaper, _________.

A. a blog would be started in her name

B. her son would receive so many letters

C. many TV shows would want to interview her

D. many TV stations would want to film her son’s story
