Kang Heng, 16, hasn’t been sleeping well in a tent the past couple of nights. Closing his eyes only brings repeated terror from all that happened and, worse still, all that could have happened at around 2:30 pm last Monday.
The student in Dongcheng High School in Mianyang, Sichuan Province was on his way to class after an afternoon nap(小睡) when the big earthquake hit the area.
“It’s a complete shock! As soon as I heard someone screaming Earthquake! I saw our classroom building being torn apart just in front of my eyes. The next second I saw a student jumping out of the window from the second floor,” Tang recalled.
As the electricity was cut off, his teachers shouted as loud as they could to gather all the students in the school onto the playground. Although some were wounded by falling objects or injured while running out, they at least escaped death.
Thousands of people, young and old, were buried in ruins, mostly in the small cities and counties, such as Wenchuan, Beichuan, Dujiangyan, Anxian and Qingchuan, which are surrounded(包围) by hills and mountains.
By last Friday, around 19,000 people died because of the earthquake, which is the worst in China in 30 years. And the number is still rising.
More than 100,000 troops have continued to arrive at destroyed areas since the day after the quake hit. And more neighboring people were doing all they can to offer help.
Kang and his parents were among them. They drove in rain to Anxian County, an hour drive away from Mianyang, with water, instant noodles and plastic for building tents. Kang’s family finally found his terrified grandparents in Anxian on Wednesday morning.
“We first thought the worst had happened to my grandparents. But they had a narrow escape and were rescued by kind people, who were completely unknown to us. We are thankful to them and hope to do whatever we could to help others,” said Kang.

The past 70 years have been good for corn production in the Midwestern United States, with yields increasing fivefold since the 1940s. Much of this improvement has been credited to advances in farming technology but researchers at Harvard University are asking if changes in climate and local temperature may be playing a bigger role than previously thought.
In a newspaper, researchers find that a prolonged(延长的) growing season due to increased temperatures, combined with the natural cooling effects of large fields of plants, have had a major contribution to improved corn production in the U.S. “Our research shows that improvements in crop yields depend, in part, on improvements in climate,” said Peter Huybers, professor of Earth and Planetary Sciences. “In this case, changing temperatures have had a beneficial impact on agricultural production, but there is no guarantee that benefit will last as the climate continues to change.
Understanding the detailed relationships between climate and crop yields is important as we move towards feeding a growing population on a changing planet. ” The researchers modeled the relationship between temperature and crop yields from 1981 to 2017 across the so-called Corn Belt. They found that as temperatures increased due to global climate change, planting days got earlier and earlier, shifting by about three days per decade. Early planting means the corn has more time to mature before the end of the growing season.
There is also a second, more surprising trend that has benefited corn yields. Whereas the vast majority of temperatures have warmed over the last century, the hottest days during the Midwestern growing season have actually cooled.
The researchers estimate that more than one quarter of the increase in crop yields since 1981 can be attributed to the twin effects of a longer growing season and less exposure to high temperatures, suggesting that the crop yield is more vulnerable to climate change than previously thought.
The researchers also show that the planting and harvest dates farmers currently use is significantly better adapted to the present climate than it would be to climates in earlier decades.
1.What is previously thought to be the reason for the increase of corn production?
A.Local temperature change. B.Advanced farming technology.
C.Climate change. D.Production efficiency.
2.Why is it important to understand the relationships between climate and crop yield?
A.The climate has a beneficial impact on agriculture.
B.We can change the climate to improve crop yield.
C.We depend on the climate to get food.
D.Crop yield relies less on the climate.
3.How many factors that benefit corn yields are mentioned in the text?
A.4. B.3.
C.2. D.1.
4.What is the main purpose of the text?
A.To explain a mystery. B.To question a common sense.
C.To show a new trend. D.To introduce a research result.
