Danny has a hobby--playing games online. He is interested     1     solving puzzles. He particularly enjoys     2     (chat) to other gamers.

Now Danny is sitting quietly in front of his computer. His mother thinks he is doing his homework,     3     she is wrong. Danny is     4    (actual) surfing the Internet, solving puzzles and talking to other gamers around the world,     5     is pretty fun!

Why are games online so interesting? “    6     I can pretend to be a different person. There are also many different    7     (kind) of games for me    8    (play),” says Danny. “Other people love to play these games because they can play at any time. They do not need to organize a group. Someone in the world always wants to play.”

Starting a game online is not easy. Some gamers don’t welcome new gamers. They will become    9     (anger) when new gamers ask them questions. Other gamers are helpful. They want to make new friends. When Danny has     10     question, he always says, “Excuse me, are you busy? I am new at this game and I need some help.” Sometimes this works. At other times, however, the gamer at the other end makes you feel like a fool.

8 . Your brain controls everything you do. It makes it possible for you to think, learn, create and feel; to blink(眨眼) and breathe and for your heart to beat--this fantastic control center is your brain. It is so amazing that a famous scientists once called it “the most complex (复杂的) thing we have yet discovered in our universe”.

Can this small gray organ(器官), which weighs less than one and a half kilos, really do so much? Amazingly, your brain contains about 100 billion neurons(神经元)--it would take you over 3,000 years to count them all. Believe it or not, the activity in your brain never stops. Your neurons create and send more messages than all the phones in the world. And although one neuron creates only a little electricity, all your neurons together can produce enough electricity to power a light bulb(灯泡).

So exactly how fast does your brain work? Well, imagine this: a bee lands on your foot. Neurons in your skin send this information to your brain at a speed of more than 240 kilometers per hour. Your brain then uses other neurons to send the message back to your foot to shake the bee off quickly. These neurons can send this information at more than 320 kilometers per hour. No computer has your brain’s unbelievable ability to deal with the amount of information coming from your eyes, ears and other sensory organs.

But how does your brain allow you to learn things that you will use in the future? The structure(结构) of your brain changes every time you have a new thought, remember or learn something. For example, riding a bike seems impossible at first, but soon your are able to do it. How? As you practise, your brain sends “bike riding” message again and again. Soon, the actions are learned and you are able to ride a bike easily from then on.

A．your brain will power a light bulb	B．your heart beats fast
C．you remember something	D．the structure of your brain changes

4. The article is mainly about ______.

A．all the steps when your brain learns things

B．what an unbelievable organ the human brain is

C．how the brain makes people smarter than computers

D．the things you can do to make your brain work faster

9 . In the modern age, human society runs on energy. Most machines need electricity to operate. Humans can not live without electricity even a single day both in their daily life and work. They have many different ways to create electricity. But some ways are harmful to the environment.

For example, fossil fuels (化石燃料) are the most common kind of energy. They include coal, oil, and natural gas. First, people have to dig them from the ground. This can sometimes harm the environment. However, scientists are creating cleaner and better ways to do that these days. So the environment is not harmed as much as before. But when people burn these fossil fuels, they can give off a lot of harmful gases, which is considered to be one of the greatest causes of global warming. This might harm the environment.

Tidal (潮汐) energy is another way to make electricity. This uses the ocean tides to make electricity. But some kinds of tidal energy can kill many fish and other sea animals. Also dams (大坝) can create lots of clean energy. But dams create lakes and change the way that rivers run. So they can do great harm to the balance of nature around the lakes and along the rivers.

Nuclear (核) energy is a very powerful form of energy. It is cheap. It is also very clean. But many people are afraid of it because it uses radioactive materials. Also, there have been some every serious accidents in the past which caused great harm both to humans and nature. But the technology is much better these days. So many countries are starting to use nuclear energy more.

10 . Have you ever heard of a rattlesnake? It is a poisonous (有毒的) American snake. When it is angry or afraid, it makes a noise like a rattle with its tail. It’s very scary. But Heather Ramirez and her husband, from California, the United States, make a living in an unusual way. They are self-employed (自雇的) snake catchers! They catch snakes, especially rattlesnakes which have gone indoors, and return them to the wild.

Heather describes her work as “protecting people from rattlesnakes--and protecting rattlesnakes from people!” In the area where they live, rattlesnakes often come face to face with people. They are found in stores, offices, houses and gardens. Heather explains that it’s not the snakes that are moving into places where people live, but it’s the other way round. The snakes lived in these places first and then the people built houses.

Most people who see a rattlesnake are feared. If you keep your distance, however, the snake won’t bite (咬) you. In twelve years as a snake catcher, Heather has never touched a snake. She doesn’t take the risk. She picks up the snake with a special tool. This doesn’t hurt them, but it keeps them at a safe distance so that they can’t bite her.

Heather and her husband are very busy because they are never off duty. Catching snakes is a full-time job and they don’t often have a day off. People can get to them at any time of the day or night. Not everyone can do this job, but Heather doesn’t want to do anything else. “I just love my job,” she says.
