Imagine looking at something and being able to move it just by using your brain!That is exactly what the new technology called BrainGate can do —with the help of a robotic arm,anyway.

BrainGate is the idea of Professor John Donoghue and his team of researchers at the Brown Institute for Brain Science,USA. BrainGate is attached directly to the brain. First of all,gold wires are put into the part of the brain that controls movement. These are then connected to a small computer chip(芯片) . When the person thinks about different movements,this creates electrical signals,which are picked up by the chip. After this,the signals that are created by the brain are sent back to a computer,which changes the signals into movements. Finally,the computer uses the robotic arm to carry out these movements. BrainGate can already be used to write an e-mail or play computer games,just by brain power.

The technology has already cost millions of dollars to develop and when it is available for use,it will probably cost thousands of dollars per person. There are still many challenges ahead for Donoghue and his team. They are currently planning a mini wireless version,which will allow people to be connected to the computer at all times. Donoghue also dreams of using this technology to help disabled people who can't move their arms or legs. He plans to connect BrainGate directly to their own paralysed limbs(癱瘓的胳膊或腿) .This will mean that the person can control their own body again,without relying on a robotic arm.

This research is attracting the military's (軍方的) attention as well. However,it is easy to understand why scientists might be concerned about how thought-controlled machines could be used by the military.

1.What does the underlined word “These” refer to?

A. Movements. B. Thoughts.

C. Brains D. Wires.

2.What is one of BrainGate's disadvantages?

A. It needs improvement. B. It produces few movements.

C. It is too expensive. D. It is difficult to control.

3.How will Donoghue help disabled people?

A. By developing a wireless version.

B. By replacing their limbs with robotic ones.

C. By making BrainGate smaller.

D. By attaching BrainGate to their bad limbs.

4.What does the military think of thought-controlled machines?

A. They could lead to disasters. B. They would face fierce competition.

C. They could be useful. D. They would be in mass production.

【題目】During my free time one day, I wandered down a lonely path into the woods and sat against a tree. Then I saw one of the camp counselors approaching me. "Oh great," I thought, since counselors were always trying to cheer you up or make you laugh.

"Hey," he said, "mind if I have a seat?" I shrugged(聳肩). I wasn't going to encourage him, but I couldn't exactly stop him, either. He sat down alongside me and extended a hand. "I'm Gary," he said, "and you're Erica, right?" I nodded. "You don't exactly look like you're having a good time," he began.

I crossed my arms and gritted my teeth. "Look," I said, "I didn't want to come to camp, I don't like it, I'm not having fun, and it basically stinks." I glared at Gary.

"So there's nothing here at all for you, huh?" he asked.

"Nothing," I answered.

"Let me show you something," said Gary. He got up, and I followed him along the path until I heard a sound like a roaring freight train.

"What's that?" I asked.

"Wait and see," he replied, with a small smile.

When we rounded the corner, I couldn't believe what I saw. There was the biggest waterfall I could ever imagine, right in front of me. "Cool!" I said, and I could feel my eyes getting bigger and a smile tugging at my mouth.

"Still think there's nothing here for you?" asked Gary. "Because there's a whole lot more of this kind of 'nothing' around here."

I had to admit, the waterfall was impressive.

"Look," said Gary, "camp is what you make it. You can be sullen(陰郁的) and closed-minded and have a rotten four weeks, or you can take a look around you and see some of the incredible sights and appreciate the opportunity. It would be useless for me to try to make you have fun. You can only do that for yourself. But if you loosen up a little, you might actually have a good time." With that, he turned and walked away, leaving me on the path.

That night, by the campfire, I found myself singing along with everyone else. By the time the four weeks were up, I didn't want to leave. I'd seen some amazing things and made some great friends.

Beauty is where you find it. Life is what you make it. I think it's going to be a good year this year. I mean, I'm going to work to make it one. Maybe if I'm lucky, I'll get to go back to camp next year!

【1】When Gary walked to Erica, you could predict that ________ .

A. She has many close friends at home.

B. She is looking forward to the future.

C. She's a good student who gets mostly A's.

D. She often gets into trouble at school.

【4】What does the underlined word “counselor” most probably mean in Para 1?

A. A person who teaches you how to make fun of others.

B. A person who gives you help and advice.

【題目】The Great Fire of London started in the very early hours of 2 September 1666. In four days it destroyed more than three-quarters of the old city, where most of the houses were wooden and close together. One hundred thousand people became homeless, but only a few lost their lives.

The fire started on Sunday morning in the house of the King's baker in Pudding Lane. The baker, with his wife and family, was able to get out through a window in the roof. A strong wind blew the fire from the bakery into a small hotel next door. Then it spread quickly into Thames Street. That was the beginning.

By eight o'clock three hundred houses were on fire. On Monday nearly a kilometer of the city was burning along the River Thames. Tuesday was the worst day. The fire destroyed many well-known buildings, old St Paul's and the Guildhall among them.

Samuel Pepys, the famous writer, wrote about the fire. People threw their things into the river. Many poor people stayed in their houses until the last moment. Birds fell out of the air because of the heat.

The fire stopped only when the King finally ordered people to destroy hundreds of buildings in the path of the fire. With nothing left to burn, the fire became weak and finally died out.

After the fire, Christopher Wren, the architect, wanted a city with wider streets and fine new houses of stone. In fact, the streets are still narrow; but he did build more than fifty churches, among them was new St Paul's.

The fire caused great pain and loss, but after it London was a better place: a city for the future and not just of the past.

A. many famous buildings were destroyed

B. the birds in the sky were killed by the fire

C. some people lost their lives

D. the King's bakery was burned down

【2】Why did the writer cite (引用)Samuel Pepys’ words?

A. Because Pepys was among those putting out the fire.

B. Because Pepys also wrote about the fire.

C. To give the reader a clearer picture of the fire.

D. To show that poor people suffered most.

【3】How was the fire put out according to the text?

A. Houses standing in the direction of the fire were pulled down.

B. All the wooden houses in the city were destroyed.

C. People managed to get enough water from the river.

D. The king and his soldiers came to help.

【4】Which of the following were reasons for the rapid spread (擴(kuò)散)of the big fire?

(a) There was a strong wind.

(b) The streets were very narrow.

(c) Many houses were made of wood.
