More and more scientists are interested in learning about dinosaurs. They want to find out the reasons why dinosaurs died out.

We can know about the weather by listening to the weather report. We can also know the weather in some other ways. Let’s see what Tom and Wang Hong found on the Internet.
	When we see birds fly high out to the sea, we know it is a nice day because birds don’t like to fly out if it rains. When the weather is bad, the birds will come back to the beach. A big wind may come with a heavy rain. Birds do not like to fly in a big wind. They may sit in a tree when the rain is coming.
	It is a cloudy day. The rain is coming. Chickens are not quiet and they run here and there. Frogs (青蛙) make a big noise in the pool. If it is a nice day, the frogs will come out of the water.

5 . Do you often feel cold in winter? When you feel cold, what do you do to warm yourself up? Do you put on more clothes? When it’s cold, how do you sense that?

I like to take a bath. I like the way the warm water feels on my skin. I do not like to get out of the bathtub (浴缸). When I get out of the bathtub, I get really cold. Sometimes I am so cold that my teeth begin shaking, and I start to shiver (颤抖). Why do we shiver when we are cold?

Shivering is a reflex (反射). We don’t have to think about a reflex in order to make it happen. When the air around us suddenly becomes cooler, the nerves (神经) in our skin sense that we are cold. These nerves then send messages to our brain. The brain sends messages back that race through our bodies. These messages tell all of our muscles (肌肉) to start warming up.

Our muscles then start tightening (绷紧) and relaxing. They do this very quickly over and over again. These quick actions are the shivers. These shivers help to warm us up. So the next time you start to shiver, thank your nerves. They’re working to warm you up before you even have the chance to shout, “Mom, I’m c-c-c-old!”

6 . Parts of a Plant

There are more than 400,000 kinds of plants on Earth. Some plants are as big as tall buildings; others are as small as rice. Plants are key parts of the food circle. They play an important part in the nature because they give out oxygen—the gas that all animals need for breathing.

What is a plant?

Most people have no difficulty finding the differences between an animal and a plant. That is because animals can move around, but plants can’t. What makes a plant a plant? Like animals, plants are living things that are made up of lots of cells (细胞). Unlike animals, plants make their own food by photosynthesis (光合作用). Most plants have roots, stems, and leaves, and most plants reproduce by growing flowers and making seeds. All plants need energy to stay alive and grow, and they get it from sunlight instead of food.

How does a plant grow?

Most animals grow in a certain way, and genes control their growth. That is to say, even when they are small, it’s easy to know what they will look like after they grow up. Plants are different. Their growth is controlled by genes too, but their final shape also depends on where they live. For example, a tree can be big and round if it grows up in an open space, but much taller and thinner if it grows in the woods with other trees all around. Plants are unable to move from one environment to another, so it is important that they are able to get used to the environment.

1. Which of the following is NOT mentioned in Paragraph 1?

A．The number of plants.	B．Different sizes of plants.
C．The importance of plants.	D．Planting more trees.

2. What method does the author use to describe the plants in Paragraph 2?

A．By comparing.	B．By giving examples.
C．By giving numbers.	D．By telling stories.

3. What can we know about plants from the passage?

A．Flowers and seeds are the most important parts of a plant.

B．Plants and animals grow in the same way.

C．Only environment controls the plants’ growth.

D．It’s important for the plants to get used to the environment.

4. What is the best title for this passage?

A．Different Kinds of Plants	B．The Life of Plants
C．Plants and Animals	D．All About Plants

7 . When I was young, I lived in Scotland with my parents. I had a good time there. One morning, I ran to the garden, and said to the old gardener. “Today I am going up the mountain.”

“No, no, Missey, not today,” he said, “It will rain.”

“No, it will not rain.” I said. “The sun is up.”

“I don’t care for the sun. The pimpernel (海绿) says it will rain, so it will. Flowers always tell the truth. When they say rain, go and get your umbrella.” said the old man.

Sure enough, by noon the rain was pouring (倾倒) down. After that, I looked with great respect (崇敬) at the flower. But the pimpernel is not the only plant that is a “weather prophet”(预言者).

If you find the African marigolds (金盏花) shut (合上) after seven o’clock in the morning, you may be pretty sure that there will be a rainy day. Most “weather prophet” plants shut up for rain. Tulips (郁金香) are careful not to open their cups very wide in the morning if it is probably going to rain. The cause of the opening and closing may be the difference in light. Perhaps these plants shut their flowers because of the short of light.

But some plants open for rain. The verbenas (马鞭草) are one kind of them. They love the shade and become smaller in a strong light. The roses make no changes. The light seems to make no difference to them.

On the whole, if you go into your garden, and find tulips, marigolds shut, you’d better not go for picnics or long walks.

1. Why did the old gardener think it would rain?

A．The sun told him.	B．The cloud told him.
C．The weather report told him.	D．The pimpernel told him.

2. Which one is right about the “weather prophets” plants?

A．They love shade.	B．They tell about the weather.
C．They open for rain and light.	D．They become smaller in a strong light.

3. When can you probably go out for a picnic?

A．When the verbenas do not shut.	B．When the roses shut in the sunshine.
C．When the tulips open wide in the daytime.	D．When the African marigolds shut after 7:00 am.

8 . Do you often ask questions? Children are known for wanting answers to many questions, because curiosity (好奇心) is part of human nature. Books and TV shows often depend on curiosity. People keep reading or watching because they want to find out what happens.

As we know, curiosity provides many advantages. Many of history’s greatest discoveries were made by curious people. People wondered how things worked and how work could be done more quickly. Thanks to their curiosity, people now know far more about the world and have useful technology to help them. Even if you don’t plan to be an inventor or researcher, curiosity can still help you in the classroom. If you develop the curiosity of learning, classes will become more interesting. You will be good at them because you enjoy the process of learning. Even if you’re no longer a student, curiosity will make you an able worker.

What will you do if you’re not already curious? Luckily, curiosity is a skill that can be improved. Often, the more you learn about a topic, the more interesting it becomes. To improve your curiosity, get information from as many sources (来源) as possible when you learn about a topic. At the same time, read all kinds of books, watch or listen to speeches and ask questions. Don’t always get information in the same way. Instead, learn to understand the facts that different people know.

Don’t assume you already know everything. Instead, search for other possibilities and opinions. Remember, everyone knows something that you don’t know. Find out what it is, and ask about it. This lets you learn something and makes the other people happy by letting them show off their knowledge. Let’s try to become people who are full of curiosity.

1. Children like to ask questions because they ________.

A．they don’t know human nature	B．they are born with natural curiosity
C．they like reading and watching	D．they don’t want to find the answers

2. What can curiosity help you in the classroom?

A．It can make you cleverer than before.	B．It can make the classes easier for you.
C．It can help you feel relaxed.	D．It can help you enjoy the process of learning.

3. Which can be helpful to improve your curiosity?

A．Reading only one kind of book.	B．Getting information from many sources.
C．Showing others your knowledge.	D．Getting the information in the same way.

4. What’s the best title of the passage?

A．Try to Be Curious	B．Make Others Happy
C．Learn to Ask Questions	D．Discoveries Made by Curious People

10 . 阅读短文，并按要求完成1—5题。

Every morning my father buys a newspaper on his way to work. Every evening my mother looks through (浏览) magazines at home. And every night, I look at the posters (海报) with photos of Messi and LeBron James on my bedroom wall before I go to sleep. Can we imagine (想象) life without paper or printing?

About 2,000 years ago, paper was invented in China. Then people learned to write words on paper to make a book. Because in those days, they could write books by hand. So, books were expensive and rare (珍贵的) at that time. And because there weren’t many books, few people learned to read.

Then printing was invented in China and it developed greatly at the beginning of the 11th century.

The people could print books quickly and cheaply (便宜地). As a result, more people learned to read.

After that, knowledge and ideas spread quickly.

Today with the help of the Internet we can contact each other and share information quickly. We can also read newspapers and magazines online. But will the computer replace (替代) books one day? No, I don’t think the poster of LeBron James on my bedroom wall will ever be replaced by a computer of two meters high!
