【2】C
【3】D
【解析】
【1】人口增长属于传统型的特征是高出生率、低死亡率、低高自然增长率，表中符合该特征的是乙国。
【2】丙国的人口增长特征是高出生率、低死亡率、高自然增长率，属于传统型，此时人口大量迁入，人口增长快，但无从知道人口总数和资然状况，也就不知道人均资源占有量。
【3】发达国家人口增长模式是现代型，其人口增长特征为低出生率、低死亡率、低自然增长率，表中符合该特征的是丁国。

Someone asks me what on earth happiness means? I can’t give you the exact definition of it, but I’m sure if you love and help others, you’ll get it.
I’ll never forget an old lady 1 lives in a small house alone. It’s said that her husband and her son 2 (die) in a traffic accident. How bitter her life is! But the old lady often helps others 3 a smile. Whenever it snows, she is always the first 4 (clean )the paths. She looks after several children living nearby. I am one of them. I often remember the stories she told us and her kind smile. Perhaps she is unlucky, 5 I think she is a happy person.
Her life is full of laughter and love.
But I’m sad to see some people getting their happiness in bad way. They speak loudly in cinemas and meeting rooms; they destroy trees to enjoy 6 (they) and they laugh at others’ 7 (shortcoming). Perhaps they feel happy at that time, but they will never get happiness 8 (true) because they have lost their personalities. Now I know 9 happiness is. It means kindness, love and unselfishness. Above all, only 10 (bring) happiness to others can make you get it.

说明文 | 可以发出地震警报的应用程序 | 228 | 10分钟 | ★★★☆☆ |
A new phone app uses vibrations from smartphones to alert people about earthquakes. 1 phone app recognizes sudden shaking of the earth’s surface through sensors in smartphones.
The new app is called MyShake. It is the work of four 2 (research) at the University of California, Berkeley. They said they created a worldwide warning system 3 would inform people and give them time to prepare. Other earthquake apps include QuakeFeed, Quakes and Earthquake. They show 4 earthquakes have happened, at what strength, and the aftershocks. Those use data from the U.S. Geological Survey.
Smartphones 5 (equip) with accelerometers(加速计). These instruments measure movement, like that of a car or airplane. 6 (probable), they can also measure the shaking of a machine, a building or other structures. Accelerometers are used in activity trackers and apps that count steps or other exercise. They also are used in global positioning system apps, also 7 (call) GPS.
MyShake uses phone accelerometers to measure seismic(地震的) activity. It has been designed 8 (know) the difference between normal activity and earthquake movement. The software developers say their app is right 93 percent of the time.
A smartphone sends seismic 9 (inform) to the app developers. If the developers receive several warnings from one area, it recognizes that an earthquake may be taking place 10 will take place soon.
