(2017·莆田质量检测)Economists across the world are expressing concern about rising food prices. The United Nations Food and Agriculture Organization recently released its Food Price Index.
The list showed that a number of foods cost more than during the world food crisis of 2008. The index is at its highest level since it began in 1990.
The FAO predicts that world market prices for rice，wheat, barley(大麦), sugar and meat will stay high or continue rising. One reason for this is the threat of shortages caused by bad weather.
Current and recent weather disasters have harmed agriculture and affected prices in several parts of the world. For example, the current flooding in Australia has done great damage to crops in the usually fertile Queensland area.Chickpea, wheat, sorghum (高粱) and corn are among the crops affected. Floods have also harmed other vegetables and fruits. The effects on prices from floods last year in Pakistan and China are still being felt.
Last week, Russia extended an earlier ban on wheat exports. Russia acted after heat, drought and wildfires destroyed about a third of its wheat crop last summer.
The ban was placed to make sure Russians have enough wheat. The first ban caused worldwide wheat prices climb to last year by almost 50 percent.
In Algeria, the government has reduced taxes after food riots (暴乱) late last year and earlier this month.Among the causes of the riots were price increases for cooking oil and sugar.Several people died in the riots, and hundreds of others were injured. Food prices are also part of economic problems to blame for the deadly riots in Tunisia. Shenggen Fan heads the International Food Policy Research Institute from its Washington DC office. Mr. Fan says countries must invest in making their farmers more productive. He says the world will need to feed more hungry people with less available land, water and other resources.

(2017·福州五校模拟)You're lost in the world of dreams and sleep. You roll
over, smiling as you come across a swimming pool filled with chocolate. And then, your wonderful dream becomes a nightmare (噩梦) when someone is screaming, “Get up！” It's just what every teenager goes through each morning!
Now, there seems to be one school that finally understands that requiring teens to show up at 9 am is not just cruel but also harmful to both the kids and the school.
Monkseaton High School in North Tyneside, Britain, recently decided to experiment to see if there is any difference in student behavior if they just pushed back the start of their day by one hour, from 9 am to 10 am. And the results are surprising.
Since carrying out the later start, Monkseaton has seen a 28% drop in truancy,_even hardly any lateness, and best of all, higher test scores. One of the reasons is that the teenagers are much happier to have the extra hour of sleep, but there is also a scientific reason behind why they need the extra sleep.
The school's decision to push back the time was based on the research done by Oxford Professor Russell Foster, who pointed out that teenagers and adults have different sleep cycles，explaining why teenagers go to bed late and wake up late.
While adults are wide awake and ready at 8 am, teenagers are not fully awake until 10 am, sometimes even noon. Teachers may argue that their students perform better in the morning, but in fact, it is because they are in the zone while their students are still sleepy, making the students easier to control.Memory tests prove that the more difficult classes should be in the afternoon when teenagers are most wide awake.
The Monkseaton school officials are encouraged by the results and plan on voting to make it a permanent change.
语篇解读：本文介绍英国一所学校大胆推迟早上学生的到校时间，结果学生迟到、旷课现象减少，成绩明显提高。学校准备投票决定是否永久将这项举措保持下去。
5．What's the meaning of the underlined word “truancy”？
A．grades
B．classes
C．absence
D．practice
解析：词义猜测题。根据文章可知，自实行了这项措施后，在truancy方面下降了28%，甚至几乎没有人迟到。这里讲的是实行这项措施的好处，结合四个选项，可知选C。
答案：C
6．What can we learn from the passage?
A．Teenagers and adults have the same sleep cycle.
B．Teenagers are fully awake at 10 am as a whole.
C．Teenagers are much happier to sleep than study.
D．Teenagers need the extra sleep also for a scientific reason.
解析：推理判断题。依据第五段可知学校推迟学生到校时间是有科学依据的，学生在早上需要更多的睡眠时间。
答案：D
7．Which of the following statements is NOT true according to the passage?
A．Monkseaton High School is satisfied with the result of the experiment.
B．It is very cruel for the teenagers to show up in class at 9 am every day.

D．In fact, teenagers perform better in the morning than in the afternoon.
解析：正误判断题。依据第六段最后一句推断学生下午状态更佳。学生在上午更易管理(貌似专心听讲)，是因为他们在此时还没有完全清醒。
答案：D
8．What's the best title for this passage?
