1、高考概要写作 Summary Writing,阅读下面短文,根据其内容写一篇60词左右的内容概要。 Feeding the worlds population is a big challenge, and it is about to get bigger. Right now, a little more than 7.3 billion people share the planet. By 2050, some scientists estimate, the worlds population may reach 9 billion. However, the changing cl
2、imate will probably make feeding this far greater number a very frightening task. That is the conclusion reached by some scientists. Just three cropswheat, rice and cornprovide more than two-thirds of the calories that people consume. Such crops, and a small number of other important crops, come fro
3、m farming regions sometimes referred to as “breadbaskets”. However, these areas often occupy a relatively small portion(部分) of the globe. Worse still, the breadbaskets are easily affected by bad weather. Events such as widespread flooding or extended heat wave can kill crops. Thats especially true i
4、f the bad weather occurs when a crop is young, fruiting or approaching harvest. Unfortunately, big crop failures in two or more breadbaskets could lead to what researchers call a “food shock”. That means an overall shortage of food would occur. Extreme food shocks used to happen every century. Or to
5、 put it another way, thats only about once in very four generations of humans. However, according to studies, as the climate warms, high and low temperatures become more extreme, and by 2050, food shocks could occur about once every 30 years. In other words, a person born in the middle of the curren
6、t century might live through two or three extreme food shocks during their lifetime. So what can people do to help avoid food shocks? Making agriculture efficient is one choice. But one of the most effective ways to fight against food shocks might be to cut down on food waste. “If we could cut food
