Though for many of us the year ahead may look pretty depressing, 2016
promises one great breakthrough —a major step toward ending Africa’s particular and backward form of the great Digital Divide.
Poor connectivity has bedeviled much of the c ontinent’s internet access but now
a hug improvement is coming. It’s a new sub-sea cable, to be laid off Africa’s eastern coastline, enabling a reliable and affordable international connectivity service to both
coastal and landlocked countries in Eastern, Central and Southern Africa.
The project is being developed by Liquid Sea, an offshore branch of Liquid Telecom, which already runs a pan-African network based on land cable supported by
satellite links for rural and remote areas. Altogether, with offices from South Africa
and Botswana in the south to Kenya in the East, taking in Democratic Republic of Congo in the center, it makes up the continent’s largest single connecting network crossing multiple national borders.
Africa has benefited in many ways from the digital revolution, but internet coverage still differs from place to place.
And the unpleasant truth is that, despite some great advance in African
development over the last decade and more, its effects are unequal and taken as a whole, less than 16 percent of Africans have access to the Internet, which compares that with 63 percent of Europeans and 79 percent of North Americans.
It’s obvious what a disadvantage is placed upon Africans by such digital inequality. The economics of the entire process is skewed（歪的）by poor network performance in Africa, with the total bandwidth available to shuttle data back and forth between African countries and the rest of the world amounting to less than 1 terabit per second. That’s about one-seventieth of Europe’s int ernational bandwidth capacity.
Now Liquid Sea’s underwater cable stretching from eastern South Africa to the Middle East, with onward connections to Europe, aims to contribute much more in building Africa’s better connected digital future.
28. What does “bedeviled” most probably mean in Paragraph 2?
A. attracted
B. troubled
C. worsened
D. contributed
29. What would the Internet be like in Africa in the future?
A. Dependable and inexpensive .
B. Accessible and comfortable.
C. Central and controllable.
D. Possible and comparable.
30. What is implied in the passage?
A. International bandwidth capacity makes no difference.
B. Internet connections improve the equality in Africa.
C. Poor internet access limits the economy of Africa.
D. Africa is now far beyond developed countries.
31. Which of the following is the best title for the passage?
A. Unsafe Internet access in Africa
B. Digital-gap narrowing in Africa
C. Bandwidth available in Africa
D. Great Digital Divide in Africa
B
NEW cars that can control and brake themselves risk quieting people in the
driver's seat into a false sense of security 一and even to sleep.
That was one surprising finding when researchers put Stanford University
students in a simulated(模拟的）self-driving car to study how they reacted when their
robot-chauffer needed help. The experiment was one in a growing number that assesses how cars can safely hand control back to a person when their self-driving software is at a loss.
With some models already able to stay in their lane or keep a safe distance from
other traffic, and automakers pushing for more automation, the car-to-driver handoff is a big open question. The elimination(消除）of distracted driving is a major selling point for the technology. But in the Stanford experiment, reading or watching a movie helped keep participants awake. The Stanford research suggests engaging people with media could help, while some automakers are marketing vehicles with limited self-driving features that will slow the car if they detect a person has stopped paving attention to the road. Though research is ongoing, it appears that people need at least 5 seconds to take over.
Meanwhile, traditional automakers are advancing with the technology. Mercedes and Toyota sell cars that can hit the brakes and stay in their lane. By adding new features each year, they might produce a truly self-driving car in about a decade. One potential risk of this gradualist approach became clear this fall, when Tesla Motors had to explain that its "auto pilot" feature did not mean drivers could stop paying attention. Starting late next year, the Cadillac CTS will get a Super Cruise system, which will allow semi-autonomous highway driving. If the driver's eyes are off the road, and they don't respond to repeated urging, the car slows.
"We are in no way selling this as a technology where the driver can check out," General Motors spokesman Dan Flores said, "You can relax, glance away, but you still have to be aware because you know the technology's not safe."
One riddle automakers must solve: How to get owners to trust the technology so they'll use it ― but not trust it so much that they'll fall into a false sense of security. Trust was on the mind of researchers who in August published an extensive report on self-driving cars. "Although this trust is essential for widespread adoption, participants were also observed prioritizing non-driving activities over the operation of the vehicle," the authors wrote. Another wide-open question: How to alert the person in the driver's seat of the need to take over. It appears that the car should appeal to several senses. Visual warnings alone may not be enough.
32.In the experiment, one disadvantage of the self-driving car is that in the drivers' seats people ______________
A. have a sense of security because of new technology
B. can't react immediately when they need help
C .are often distracted while driving the car
D. like to read and watch a movie to keep awake
33.What does the underlined word "handoff" in Paragraph 3 probably mean?
A. change
B. control
C. pull
D. push
34.From the passage, we can conclude that____________
A. the automakers are proud of the new cars for their technology
B .there are problems to solve in getting owners to trust the technology
C .automakers have already marketed cars with limited self-driving technology
D. traditional automakers rather than present ones are advancing with the technology
35.The author's purpose of writing the passage is to____________
A. remind the readers of risks in the self-driving car
B. advertise and market the new self-driving car
C. get more participants to experiment in the self-driving car
D. introduce the advanced technology in the self-driving car
根据短文内容,从选项中选出能填入空白处的最佳选项。有两项为多余选项。
Researchers have shown that your talent for happiness is, to a large degree, determined by your genes . 36 We can do this by overcoming negative emotions and developing positive emotions.
Strategy1: 37
The first step is to make a choice to be happy. In Seeking Happiness, Bertrand Russell said, “Happiness must be an achievement rather than a gift of the gods, and in this achievement, effort must play a great part.”
Once you’ve decided to be happier, you can choose strategies for achieving happiness.
Strategy 2: Develop gratitude.
In Authentic Happiness, psychologist Martin Seligman encourages readers to perform a daily “gratitude exercise”. 38
Strategy 3: Remember, money can’t buy happiness.
Research shows: 39 Yes, “we alway s think that some things are wrong because they cannot bring us happiness,” writes Daniel Gilbert in Stumbling on Happiness.
Strategy 4: Take part in meaningful activities.
“People are seldom happier,” says Jackson, “than when they’re doing meaningful acti vities”. Yet, he has found that the most common leisure activity — watching TV — produces some of the lowest levels of happiness. 40 Active leisure that helps a person grow does not come easily, he writes in Finding Flow.
A. Achieve happiness.
B. Choose to be happy.
C. Yet, psychologists believe we can pursue happiness.
D. To get more out of life, we need to put more into it.
E. Happiness is decided by a good many aspects.
F. This shifts people away from bitterness, and promotes happiness.
G. More money doesn’t necessarily bring extra happiness.

Kaighn said he had been 47 to have the dog in his home, but agreed because Atticus was well-mannered and patient with children— 48 suddenly he wasn't.
When Gracie came rolling into the emergency room, her attending doctor said, "She was just so 49 Her parents were really upset and she was 50 them and telling them it would be OK... 51 amazingly, the wounds to her face 52 missed her eye and her ear."
Her teacher Kristine Lowder has been visiting her to tutor her. Lowder said the news of the dog attack left her 53 for days. "She is so lively, a happy-go-lucky kind of girl who was the 54 of grace in our class."
Gracie has 55 many people in a similar way. And Grade's mom said her girl has never missed a beat since she came home. She will return to gymnastics soon.
Gracie was never a bit worried about 56 to the basement where she had been so bitterly 57 —and she was upset when she learned Atticus would be 58 as a result.
"I don't want him to die, I just don't want to see him again," she told her family.

阅读下面材料，在空白处填入适当的内容（1个单词）或括号内单词的正确形式。
Two things I did may have caused people (think) that something is wrong with me. The first was when my wife asked me to have the sitting-room clock 2(repair), I drove into the marketplace of our little town and, clock under arm, entered a shop. Only it was the meat ship, my thoughts far away, I stood staring into the shop--keeper's eyes. I (be) his customer for a long time and the good man smiled at me.
This went on for several very long seconds before I realized where I was. There is no doubt that I should have calmly bought a pound of meat, I merely nodded briefly and left.
The other man in my town who probably thinks I am mad is Mr. Smith. Some years ago he was manager of Mead's Shop, and he and I knew each other quite well. One day he (stand) in the doorway of his shop when I passed. My brain was on some distant problem and my eyes stared into space.
“Hello, Mr. Herriot.” I heard his voice. I turned a blank gaze on him — I just had no idea he was though his face was familiar. Then I saw __ word “MEAD” in foot-high letters above the shop window.
“Good morning, Mead,” I cried heartily and continued my way. I had gone only a few steps before I realized that my greeting had been __(polite). I turned back and said to him again, “Good morning, Mister Mead.”
It was only when I has turned the corner of the street that I realized, too late , __ his name was Tony and the time was late afternoon.
