People always have communication with each other. In the past when they couldn't write, they used simple symbols to send their messages. Some groups of North American Indians were good at __________messages. For example, a small stone on top of a large one meant "This is the way." If there was another small stone on the right, it meant "Turn right." Some grass with a knot meant "Danger!" and so on.

In forests of Africa, it was __________to travel between villages. But drum could be heard from many kilometers away. So, some groups of Africans made their drums "__________" like people.

The Incas of South America used to send messages by tying knots with ropes. Messages have been found, but __________can understand what they mean. And the Egyptians used pictures as a kind of __________, but only a few people were __________ to understand them.

Today, we also use a lot of symbols. When we are in a car and we see a red light, we stop the car. When a mother says to her child, "Eat your cake!" the child eats the cake. Sometimes the red light and the words of the mother are symbols. And the __________ of course, is that the __________ way of communication between people is sound.

There are more than 3,000 languages in the world today. And about 13 of them are spoken by large groups of people. Languages of the world are both similar and different. They are similar because we can talk and write about the same things. They are different because we talk and write about these things with different __________.

When we exercise hard, we burn fat. But have you ever wondered where exactly the fat goes?

Some doctors think that fat is changed into heat and released in the air. Others think the body burns it. Some even joke that the fat fairy comes and takes it. That is why you always weigh less in the morning.

Now a new study from the University of New South Wales in Australia reveals the mystery. “the correct answer is that most of the mass is breathed out as carbon dioxide(二氧化碳). It goes into thin air,” says the study’s lead author, Ruben Meerman, to Science Daily. Scientists followed the atoms(原子) in 10 kilograms of fat as they are lost. They found that 8.4 of those kilograms are breathed out as carbon dioxide through the lungs. The rest of the weight —1.6 kilograms— becomes water that leaves the body in the form of fluids(液體) such as urine(尿), sweat, breath and tears. “None of this is obvious to people because we can’t see the carbon dioxide gas we breathe out,” said Meerman.

Does that mean you can lose more weight by breathing more? It is not as easy as you think. Breathing more than the body’s metabolic rate(新陳代謝) can make you uncomfortable. You may feel dizzy and become unconscious(無(wú)意識(shí)的), according the study. So how to lose weight healthily? The key is to eat less and move more. You many have heard this many times.

During a day, a 70kg person breathes out about 200g of carbon dioxide. So if the same person wants to lose weight, he or she can do some light exercise, for example, jogging. This can help lose 240g of carbon dioxide.

1.According to the new study, where does our fat go when we exercise a lot?

A.It is changed into heat and given off in the air. B.The body burns it.

C.The fat fairy comes and takes it. D.Most of it is breathed out as carbon dioxide.

2.What will happen to people if they breathe more than the body’s metabolic rate?

A.They will put on more weight. B.They will feel comfortable.

C.They may become unconscious. D.They may not lose weight at all.

3.Which of the following is a better way to lose weight?

A.Sitting still and breathing more. B.Sleeping a lot and breathing a lot.

C.Eating less and exercising more. D.Eating more and doing some light exercise.

4.Which is true according to the study from University of New South Wales?

A.The fat is changed into heat and released in the air.

B.Most of the kilograms of fat as they are lost are breathed out as carbon dioxide.

C.People can see the carbon dioxide gas we breathe out.

D.If we breathe more than the body’s metabolic rate, we will feel good.

5.During a week , how much carbon dioxide does a 70kg person breathes out?

A.240g B.200g C.1400g D.1680g

There was once a very wide tree in South Africa. 60 people could stand in its hollow trunk(空心樹(shù)干). The tree reached over 18 meters into the sky and it was more than 1, 100 years old. But recently, that tree and others like it have died.1.

The tree was a baobab(猴面包樹(shù)). Baobab trees grow in Africa and are called"the Tree of Life”.

Baobab trees usually live a long time. One of the oldest stood for more than 2, 400 years.

2.They noticed that nine of the thirteen oldest baobab trees and five of the six largest died in the following 12 years.

Stephan Woodborne, one of the six scientists, says more research(研究)is needed to know why the trees died.3.That's because the trees clearly weren't sick. Besides, many were in national parks, so they were protected from human activities. They believe that increasing temperatures and changing rainy seasons have made it harder for baobabs to live.

"The big ones and the old ones caught the attention of people, Woodborne says. "But it's not just those. 4.People should be more environment-friendly. It is one way to help protect baobabs and other trees from the effects of climate change, according to Woodborne. 5.

“We need to think about the way we live our lives. "Woodborne says. "If we all change what we do a little bit, it will start to make a difference.”

A.That could mean using less energy(能源) and making less waste(廢料), when possible.

B.Smaller and younger baobabs are dying too.

C.However, they think climate change may be the main reason.

D.Scientists are wondering why.

E.In 2005, scientists began a research to find out the age of more than 60 baobabs.

One morning when I was 11, I explored the town’s abandoned (廢棄的) round grain barn. I found a chained sliding door that was wide enough for me to pass through.

Inside, there was a heavy smell of dead mice in the dark. After my eyes adjusted, I noticed a shaft (通風(fēng)管道) that rose all the way to the top of the barn. On one side was a one-man elevator with a long rope and roller.

I stepped onto the platform, gave the rope a drag and the elevator began sliding up the shaft, but stopped halfway. After a brief panic attack, I noticed there were some holes formed a ladder (階梯). For reasons known only to an 11-year-old, I decided it would be better to go up than down. So, with shaking hands, I began climbing up.

After what seemed like forever, I reached the top of the shaft. I stood up and found nothing of interest. It was just an empty room with a ladder leading up to the roof. I tried my best to climb all the way up but it was very difficult. There was too much heavy dust. When dust was blown, I even couldn’t breathe. I didn’t know how long it took but luckily I climbed up, popped the straw roof and saw a bright blue sky.

I suddenly realized the dust and powder pouring out of the top could draw attention. So when the dust had settled, I climbed down and slipped out of the chained door. I’m not sure if I was more excited about being alive or about not being caught, but I ran all the way back home.

1.Which picture can match the passage?

A. B.

C. D.

2.When the author got inside the barn, he________.

A.noticed a man on the elevator B.opened the chained sliding door

C.saw many dead mice in the dark D.found a shaft leading to the top

3.Which of the following is the right order of the author’s adventure?

a. The elevator stopped halfway. b. He entered the round grain barn.

c. He climbed to the top of the shaft. d. He slipped out of the chained door.

A.b-a-c-d B.a-c-b-d C.c-a-d-b D.b-c-a-d

4.From the passage, we can learn that the author was probably a boy full of ________.
