According to a new survey. Students’ safety has become a big problem. Nearly 50% of students say they are worried about robbery (抢劫) on the way to and from school. Now in some big cities in China, some schools have taught an unusual lesson: self-protection. Students like this lesson because there are no exams or boring classes. And they can learn how to save lives and know how to stop danger before it really happens.
Chen Haoyu, a teacher at Beijing No 25 Middle School gives young students advice on how to deal with danger:
If you are robbed
Keep calm. If you cannot cry for help or run away, give the robber your money. Try to remember what the robber looks like and tell the police later.
If you are in a traffic accident.
If a car hits you，you should remember the car number. If it is a bicycle, try to call your parents before you let the rider go. This is because you don't know how badly you are hurt.
If it is raining hard and there is lighting. (闪电)
Don’t stay in high places and stay away from trees.
When there is a fire.
Run away as fast as you can. Put wet things on your body and try to find an exit. Do not take the lift.
If someone is drowning(溺水)
If you can’t swim, don’t get into the water. Cry out for help.
Remember that danger is never as far away as you think. Take care of yourself at all times!

Look at the plant in the picture. It looks beautiful, right? Can you imagine (想象) it kills?

The Venus flytrap is a kindof meat-eating plant. It grows in very few places, like wetlands near the sea in North Carolina in America.
The Venus flytrap is not a large plant. It grows to be only about a foot tall. The plant has white flowers in the spring, but it is the plant’s leaves that make it so interesting. The ends of the leaves have folding parts with stiff, tiny hairs (带小硬刺的可折叠部分). These are the plant’s “traps (捕捉器)”.
What does the Venus flytrap eat? As you might guess, the Venus flytrap eats flies (苍蝇). It also eats spiders, ants and crickets (蟋蟀). The Venus flytrap makes most of its food with sun, air and water, just like other plants. Living things just give it extra nutrition (额外营养) to grow well in wetlands.
How does this plant trap and eat living things? The Venus flytrap uses a sweet liquid (液体) to attract its food. When a fly lands on one of the plant’s open traps, hairs on the surface make the trap close. And when the trap closes, the fly is dinner!
If you want to have your own Venus flytrap at home, you have to buy the plant from a special place. You can’t take a Venus flytrap from where it grows! There are laws about taking it out of the wild.
Where does the Venus flytrap grow?

A．In the wetlands.

B．In the desert.

C．In the rocks.

D．In the sea.

About the Venus flytrap, which of the following is true?

A．It is a large plant.

Which is the right order of the following events in Paragraph 5?
a. The trap of the Venus flytrap closes.
b. A fly lands on one of the plant’s open traps.
c. The fly is kept in the trap as the food of the plant.
d. The Venus flytrap uses a sweet liquid to attract its food.

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

How can people get a Venus flytrap?

A．They can get it from where it grows.

B．They can buy it from a special place.

C．They can grow it in their gardens.

D．They can buy it in a park.

Why does the Venus flytrap kill?

Fear may be felt in the heart as well as in the head, according to a study that has found a link between the cycles of a beating heart and the chance of someone feeling fear.
Tests on healthy volunteers found that they were more likely to feel a sense of fear at the moment when their hearts are contracting(收缩) and pumping（向---送出） blood around their bodies, compared with the point when the heartbeat is relaxed. Scientists say the results suggest that the heart is able to influence how the brain responds to a fearful event, depending on which point it is at in its regular cycle of contraction and relaxation.
Sarah Garfinkel at the Brighton and Sussex Medical School said: "Our study shows for the first time that the way in which we deal with fear is different depending on when we see fearful pictures in relation to our heart."
The study tested 20 healthy volunteers on their reactions to fear as they were shown pictures of fearful faces. Dr Garfinkel said, "The study showed that fearful faces are better noticed when the heart is pumping than when it is relaxed. So our hearts can also affect what we see and what we don't see - and guide whether we see fear."
To further understand this relationship, the scientists also used a brain scanner(扫描仪) to show how the brain influences the way the heart changes a person's feeling of fear. "We have found an important mechanism by which the heart and brain ‘speak’ to each other to change our feelings and reduce fear," Dr Garfinkel said.
"We hope that by increasing our understanding about how fear is dealt with and ways that it could be reduced, we may be able to develop more successful treatments for anxiety disorders, and also for those for those who may be suffering from serious stress disorder."
What is the finding of the study?

A．fear has something to do with one's health.

B．fear is a result of one's relaxed heartbeat.

C．One's heart affects how he feels fear.

D．One’s fast heartbeats are likely to cause fear.

When are people more likely to feel a sense of fear ?

A．When the heartbeat is relaxed.

B．When their hearts are contracting.

C．When people are tired.

D．When people are happy.

The study was carried out by analyzing （分析）_______.

A．the time volunteers saw fearful pictures and their health conditions

B．volunteers' heartbeats when they saw terrible pictures

C．volunteers' reactions to horrible pictures and data form their brain scans

D．different pictures shown to volunteers and their heart-brain communication

Which of the following is closest in meaning to "mechanism" in Paragraph 6?

A．Order.

B．Machine.

C．Treatment.

D．System.

This study may be useful to _______.

A．treating anxiety and stress better

B．explaining the cycle of fear and anxiety

China's first moon rover (月球车), Yutu, set off from the lander（登陆车） early on December 15, several hours after the Chang'e-3 probe (探测器) soft-landed on the moon surface.
The 140 kg six-wheeled rover touched the moon surface at 4:35 a.m., leaving deep lines on the loose moon land. This was recorded by the camera on the lander and the images were sent to the earth, according to the Beijing Aerospace Control Center. After that, the rover and lander will take photos of each other and start their own science explorations.
Earlier this morning, engineers made final checks of the environment of the landing area and the situation of the probe（探测仪）. Yutu, reached its solar panel (光板) and started to drive slowly to the moon at 3:10 a.m.. It took Yutu nearly a whole hour to complete the simple task.

Have successful people ever felt sad? Do they have any “secrets” to success? The answers to these questions can be found in US president Barack Obama’s “back to school” speech. Here is an excerpt(摘录) from his speech.
I know that sometimes, you get the sense that you can be rich and successful without any hard work—that your ticket to success is through pop music or basketball or being a TV star, when chances are, you’re not going to be any of those things.
But the truth is, being successful is hard. You won’t love every subject you study. Not all the homework will seem rather important to your life right this minute. And you may not succeed at everything the first time you try.
That’s OK. Some of the most successful people in the world are the ones who’ve had the most failures (the opposite of success). JK Rowling’s first Harry Potter book was turned down 12 times before it finally came out. Michael Jordan was cut from his high school basketball team, and he lost hundreds of games and missed thousands of shots (投篮) during his career. But he once said, “I have failed over and over again in my life. And that is why I succeed.”
These people succeeded because they understand that you can’t let your failures beat you—you have to let them teach you. You have to let them show you what to do differently next time.
No one’s born being good at things. You become good at things through hard work.
Don’t be afraid to ask questions. Don’t be afraid to ask for help when you need it. I do that every day. Asking for help isn’t a sign of weakness; it’s a sign of strength. It shows you have the courage to tell when you don’t know something, and to learn something new.
And even when you’re struggling(奋斗), even when you’re discouraged (泄气), and you feel other people have given up on you—don’t ever give up on yourself. Because when you give up on yourself, you give up on your country.
Why does Barack Obama mention (提到) JK Rowling and Michael Jordan in the third paragraph?

A．To compare these two famous persons.

B．To explain that the more failures he has, the more successful he is.

C．If you want to be successful, you should fail first.

D．To show that failure is the mother of success.

Which of the following statements is NOT true?

A．No one can be successful without working hard.

B．Failure can be good if you treat it in a right way.

C．Those who believe in themselves shouldn’t ask others for help.

D．One should try his best to make his dream come true.

Which of the following has the closest meaning to the underlined sentence?

A．One shouldn’t ask questions because it is a sign of strength.

B．One should believe in himself though he will face much difficulty.

C．One doesn’t have to work hard when he has failed several times.

D．One doesn’t have to ask for help because it is a sign of weakness.

Computers can help many workers. They can also help thieves.
There was one thief who worked in a bank of the United States. He paid for everything he needed by check (支票). Then he told the computer not to take any money from his account for the checks he wrote. The bank’s computer did what he said. And it did not take any money from his bank account. One day the computer broke down. People had to do the computer’s work. They soon found out what was happening.
Another thief, who worked for a bank saw people filling in deposit forms (存款单). Many of these people did not know their account numbers, so they wrote only their names on the forms. They left empty places for their account numbers. The thief wrote his own account number in this place. When the computer read these forms it looked only at the account numbers. It did not look at the customers’ names. It paid the money on these deposit forms into the thief’s account .                           
Then there was the bank worker who told the bank computer to take ten cents off every customer’s account each month and put it into his own account. For a long time the bank’s customers did not notice that they were losing ten cents every month. But then someone did notice and told the bank. That was the end of that little game!

B．A customer.

C．A bank worker.

A．He broke the computer down and stole money from it.

Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us.
If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering(不开花的) plants.
Flowering plants can make seeds(种子). The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit.
Most non-flowering plants do not grow from seeds. They grow from spores(孢子). Spores are very, very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores fall on wet and shady(阴凉的) places, they usually grow into new plants.
What fact does the passage lead you to believe?

A．Of all living things, animals are most important.

B．Spores are seeds.

C．All fruits of flowering plants have seeds.

D．Without plants, man will die out.

The paragraph following the passage will be about ________.

A．how plants can make food from air

B．how spores grow into new plants

C．why some plants have no seeds

D．why non-flowering plants are more important than flowering plants
