题目内容

A device that stops drivers from falling asleep at the wheel is about to go through testing at

Department of Transport laboratories and could go on sale within 12 months

The system, called Driver Alert, aims to reduce deadly road accidents by 20% - 40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to tiredness

Driver Alert is based on a computerized wristband （手表带） The device, worn by drivers or pilots, gives out a sound about every four minutes during a car journey. After each sound the driver must respond by squeezing（挤压）the steering wheel （方向盘）. A sensor in the wristband detects this pressing action and measures the time between the sound and the driver’s response.

Tiredness is directly related to a driver’s response time. Usually, a watchful driver would take about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy

In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver’s response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible

The device has been delivered to the department’s laboratories for testing. If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year

1．According to the text, Driver Alert ______

A．aims to reduce tiredness-related accidents

B．has gone through testing at laboratories

C．aims to prevent drivers from sleeping

D．has been on sale for 12 months

2．How should a driver respond to the sounds from Driver Alert?

A．By sounding a warning

B．By touching the wristband.

C．By checking the driving time

D．By pressing the steering wheel

3．When the driver gets sleepy while driving, Driver Alert ______

A．moves more regularly

B．stops working properly

C．opens the window for the driver

D．sounds more frequently and loudly

Plants can’t communicate by moving or making sounds, as most animals do. Instead, plants Produce volatile compounds, chemicals that easily change from a liquid to a gas. A flower’s sweet smell, for example, comes from volatile compounds that the plant produces to attract insects such as Bugs and bees.

Plants can also detect volatile compounds produced by other plants. A tree under attack by Hungry insets, for instance, may give off volatile compounds that let other trees know about the Attack. In response, the other trees may send off chemicals to keep the bugs away ——or even Chemicals that attract the bugs’ natural enemies.

Now scientists have created a quick way to understand what plants are saying: a chemical Sensor（传感器）called an electronic nose. The “e-nose” can tell compounds that crop plants make When they’re attacked Scientists say the e-nose could help quickly detect whether plants are being Eaten by insects. But today the only way to detect such insects is to visually inspect individual Plants. This is a challenging task for managers of greenhouses, enclosed gardens than can house Thousands of plants.

The research team worked with an e-nose than recognizes volatile compounds. Inside the device, 13 sensors chemically react with volatile compounds Based on these interactions, the e-nose gives off electronic signals that the scientists analyze using computer software.

To test the nose, the team presented it with healthy leaves from cucumber, pepper and tomato plants, all common greenhouse crops. Then scientists collected samples of air around damaged leaves from each type of crop, These plants had been damaged by insects, or by scientists who made holes in the leaves with a hole punch（打孔器）. The e-nose, it turns out, could identify healthy cucumber, pepper and tomato plants based on The volatile compounds they produce, It could also identify tomato leaves that had been damaged. But even more impressive, the device could tell which type of damage ---- by insects or with a hole Punch ---- had been done to the tomato leaves.

With some fine-tuning, a device like the e-nose could one day be used in greenhouses to quickly spot harmful bugs, the researchers say. A device like this could also be used to identify fruits that are perfectly ripe and ready to pick and eat, says Natalia Dudareva, a biochemist at Purdue University in West Lafayette, Ind. who studies smells of flowers and plants. Hopefully, scientists believe, the device could bring large benefits to greenhouse managers in the near future.

We learn from the text that plants communicate with each other by____.

A. making some sounds B. waving their leaves

C. producing some chemicals D. sending out electronic signals

What did the scientists do to find out if the e-nose worked?

A. They presented it with all common crops.

B. They fixed 13 sensors inside the device.

C. They collected different damaged leaves.

D. They made tests on damaged and healthy leaves.

According to the writer, the most amazing thing about the e-nose is that it can___.

A. pick out ripe fruits

B. spot the insects quickly

C. distinguish different damages to the leaves

D. recognize unhealthy tomato leaves

We can infer from the last paragraph that the e-nose_____.

A. is unable to tell the smell of flowers

B. is not yet used in greenhouses

C. is designed by scientists at Purdue

D. is helpful in killing harmful insects

Have you listened to music on an iPod? Used a computer at home? Those are just two of the ways your life was touched by the work of Steve Jobs.

Jobs, one founder of Apple Computers, died on Wednesday, October 5, 2011 at the age of 56. He had been fighting with cancer since 2004.

Steven Jobs was born in Los Altos, California. He and his childhood friend, Steve Wozniak, designed and built the first Apple computer in his parents’ garage in the 1970s. The Apple II, built when Jobs was just 21 years old, was the first personal computer to be widely sold to the public.

Steven Jobs didn’t stop there. He went on to invent more devices (设备) that allowed people to bring their own creativity to computing: the Macintosh, the iPod, the iPhone, the iPad. People found his products beautiful and easy to use.

Jobs also changed the music and film industries. He started Pixar, a film production company in 1986. Toy Story was the world’s first computer-animated feature film (电脑动画电影).

“Steve was among the greatest of American innovators — brave enough to think differently, confident enough to believe he could change the world, and clever enough to do it,” said President Barack Obama. “By making computers personal and putting the Internet in our pockets, he made the information revolution not only easy to reach, but fun ... And there may be no greater praise to Steve’s success than the fact that much of the world learned of his death on a device he invented.”

All around the world, people are talking about the effects that Jobs’ creations have had. By creating products that surprised people, he changed the way people worked and lived their everyday lives.

Nowadays, a cellphone service is available to everyone, everywhere. Probably thousands of people have already been using it, but I just discovered it, so I'm going to claim it and also name it: Fake Foning.

The technology has been working well for me at the office, but there are infinite(无限的） applications. Virtually in any public space.

Say you work at a big university with lots of talky faculty members buzzing about. Now, say you need to use the restroom. The trip down the hall will take approximately one hour, because a person can't walk into those talky people without getting pulled aside for a question, a bit of gossip, a new read on a certain line of Paradise Lost.

So, a cellphone. Any cellphone. Just pick it up. Don't dial. Just hold that phone to your face and start talking. Walk confidently down the hall engaged in fake conversation, making sure to tailor both the topic and content to the person standing before you whom you are trying to avoid.

For standard colleague avoidance, I suggest fake chatting about fake business:

"Yes, I'm glad you called, because we really need to hammer out the details. What's that? Yes, I read Page 12, but if you look at the bottom of 4, I think you can see the problem begins right there."

Be engaged in your fake fone conversation. Make eye contact with the people passing, nod to them, gesture keen interest in talking to them at a later time, point to your phone, shrug and move on.

Shoppers should consider fake foning anytime they spot a talky neighbor in the produce department pinching (用手捏) unripe peaches. Without your phone at your face, you'd be in for a 20-minute speech on how terrible the world is.

One important caution about fake foning. The other day I was fake foning my way past a colleague, and he was actually following me to get my attention. I knew he wanted to ask about a project I had not yet finished. I was trying to buy myself some time, so I continued fake foning with my doctor. "So I don't need the operation? Oh, doctor, that is the best news."

And then: Brrrrrrng! Brrrrrmg! Brrrrrmg! My phone started ringing, right there while it was planted on my face. My colleague looked at me, and I at him, and naturally I gasped. "What is the matter with this thing?" I said, pulling the phone away to look at it, and then putting it back to my ear.

"Hello? Are you still there?" Oops.

1.According to the passage Fake Foning is _______________________.

A．a strategy to avoid people B．a device newly produced

C．a service provided everywhere D．a skill of communication

2.In the author's opinion, in order to make fake foning look real one has to__________________.

A．talk about interesting matters B．behave politely to people passing by

C．hold the phone while walking D．appear absorbed in conversation

3.What does the last example show?

A．One effective way is to fake fone one's doctor.

B．One has to be careful while fake foning.

C．Fake foning may not cheat people.

D．Fake foning is always quite successful.

4.After his phone suddenly began ringing, the author___________________.

A．immediately started talking to the caller

B．immediately started talking to his colleague

C．put the phone away and stopped talking

D．continued with his fake conversation

5.What is the tone of the passage?

A．Critical. B．Humorous. C．Serious. D．Unclear.
