The dangers of drowsy（昏昏欲睡） driving have been widely known. Now several companies have developed face-tracking technology that can tell when drivers become dangerously sleepy.
Here is how it might work. A camera in your car monitors your facial expression, compares it to a database of expressions and determines if you are likely sleepy or distracted. The car then alerts you to pay attention or pull over.
Affectiva has developed emotion recognition technology that aims to detect when people are just starting to get tired. The idea is to catch the warning signs before drowsiness really strikes. “Actually, when someone is drowsy, that is too late.” Gabi, vice president of Affectiva said. “What if you can see trends in someone’s face about five minutes before they become sleepy?” Affectiva’s program can recognize seven different emotions and 15 facial expressions. Its standards were developed by sifting （筛选） through a database of 4 million faces from 75 countries, said Zijderveld. She suggested that carmakers could coordinate （协调）the program’s facial recognition data with oral reminders, such as sound warnings, or （nonverbal）alerts, like a change of temperature and vibrations （continuous slight shaking movements）.
Eyeris is another company working in facial analytics. Modar Alaoui, the company’s CEO, said that its software detects “eye openness” in addition to other facial indicators. The software can also read head position, which may indicate when someone begins to nod off.
These technologies aren’t the first attempt to fight drowsiness behind the wheel. Inventors came up with the similar device “sleeper beeper” to prevent sleep in cars back in 1983. The sleeper beeper was attached to a driver’s ear and would issue a noisy warning when the driver’s head nodded past a certain point. But the latest software would intervene （干涉） earlier and more effectively.
1.The camera in the car can determine if a driver is ________.
A. cold-blooded B. near-sighted
C. bad-tempered D. absent-minded
2.When will drivers be reminded to pay attention or pull over by the face-tracking technology?
A. When they are just beginning to get tired.
B. Five minutes after they become sleepy.
C. When they are really tired.
D. When they are drowsy.
3.It is most likely that the “sleeper beeper” would send out a warning by ________.
A. shaking slightly B. making noise
C. flashing brilliantly D. changing temperature
4.What is the main idea of the text?
A. The dangers of drowsy driving have been widely known.
B. Inventors have tried out the similar device “sleeper beeper”.
C. Several companies have found some ways to fight drowisness behind the wheel.
D. Face-tracking technology for drowsy driving has been developed by several companies.

“Selfie” may have been named Oxford Dictionary’s word of 2013. In effect，so widely known has the selfie become that in the past 12 months，its frequency in the English language has increased by 17000 percent，said Oxford dictionaries. However，its popularity has just earned it another honour-being voted the most annoying and overused term of the past 12 months. But I’d like to offer that maybe it isn’t so bad.
According to the Oxford online dictionary, selfie is a photo that one takes of oneself， often from a smart phone，and send them to a social media website. Women and men alike decorate their Facebook and Twitter accounts with these pictures，sometimes with exaggerated facial expressions，such as large smiles or puckered lips(噘嘴).
Let’s think about it. Someone takes about 10 selfies each time they do，and they only end up posting one or two of those. They pick the one that they feel makes them look the best. Isn’t that beautiful? In that one picture，somebody has given himself or herself confidence. Self-image is vital. In today’s society，we are so crazy about being perfect. But perhaps，with that one selfie，we feel as if we fit that need. We feel handsome，beautiful，confident，smart，happy，and content. For that moment，everything bad or terrible that has ever happened to us seemed to have been erased，for that smile or that pucker is what gives us the determination to love ourselves.
A spoken-word poem I saw lately set me thinking：If I ask you what you love，the answers will most likely roll of your tongue. You love to read. You love to write. You love birds，music…your mom，your brother，your sister，your daughter，your best friend，your dog. How long do you think you could go on and on before you said，“I love myself.”?
The poem hit me like a ton of bricks. I’ve struggled with confidence all of my life. And I still do. And in no way am I saying that taking a selfie is a gateway to that confidence. However，the selfie does deserve some credit for allowing individuals to express themselves. Just as Pamela Rutledge put it，“There are many more photographs available now of real people than models.”
1.According to the writer, we live in a society where ________.
A. selfie leads to success
B. a good image decides one’s status
C. one’s poor performance can be erased
D. being perfect is highly valued
2.The spoken-word poem mentioned in the 4th paragraph implies ________.
A. our pleasure to enjoy beauty
B. our need to love people around us
C. our tendency to ignore ourselves
D. our real love to share with others
3.What does the underlined word “credit” in the last paragraph mean?
A. praise B. grade C. trust D. fame
4.In the writer’s opinion, selfie ________.
A. brings about people’s sense of confidence
B. is merely popular among teenagers
C. tells the true meaning of life
D. is an annoying phenomenon on the Internet

Scientists around the world have been studying the warming of waters in the Pacific Ocean known as El Nino. The appearance of El Nino is known to affect the weather around the world. Scientists still do not completely understand it. Yet they now find they can use it to tell about the future in different areas of the world.
One example is the work of two scientists at Columbia University in New York, Mark Cane and Gordon Eshel. A scientist of Zimbabwe（津巴布韦）, Roger Buckland worked with them. They have found that when El Nino appears, Zimbabwe has little or no rain. This means corn crops in Zimbabwe are poor. The last El Nino was in 1991 to 1993. That was when southeastern Africa suffered a serious lack of rain.
The scientists wrote about their recent work in the publication Nature. Their computer program can tell when an El Nino will develop up to a year before it does. They suggest that this could provide an effective early warning system for southern Africa, and could prevent many people from starving.
1.El Nino is known as ________.
A. the changing of the weather in southern Africa
B. the weather which brings drought (旱灾) to Africa
C. the warming of waters in the Pacific Ocean
D. the weather phenomenon that brings heavy rains to Africa
2.Scientists study El Nino in order that ________.
A. they can put all this information into their computers
B. they can tell why Zimbabwe has little or no rain
C. they can do some research work in this field
D. they can provide a kind of early warning to the place that will suffer from drought
3.Which of the following is TRUE according to the passage?
A. Scientists come to understand how El Nino appears.
B. Three scientists from the USA work on this subject.
C. El Nino has something to do with Zimbabwe’s poor crops.
D. Southern Africa suffered a serious drought and many people died from hunger.
