Poverty,disease and conflict have historically threatened food security. Now,rising food prices and issues like climate change add to these threats.

    A new study warns of future losses in world food production because of crop damage from changes in the weather. William Cline wrote the study from the Centre for Global Development in Washington. He says countries closest to the equator will be hardest hit. For example,he predicts that if nothing is done,global warming could cut India5 s food production by up to forty percent by the year 2080. Africa and Latin America could lose twenty percent or more.

   Governments concerned about global warming and dependence on oil are investing in biofuels from com and other plants. But Lester Brown at the Earth Policy Institute in Washington says demand for fuel crops is pushing up food prices. He says the worlds eight hundred sixty million automobile owners are now in direct competition with the two billion poorest people.

   This comes as grain supplies are at their lowest level in years. Experts see a number of reasons. These include no enough investment in agricultural technology,a loss of farmland to development,droughts and floods made worse by climate change and growing competition for water.

   Population growth also means a greater demand on food supplies. The United Nations predicts a population of more than eight billion by the year 2030.

   A. poverty and disease

   B. disease and conflict

科目：高中英語 來源： 題型：

  The Pacific island nation of Nauru used to be a beautiful place. Now it is an ecological disaster area. Nauru5 s heartbreaking story could have one good consequence—other countries might learn from its mistakes.

    For thousands of years,Polynesian people lived on the remote island of Nauru,far from western civilization. The first European to arrive was John Feam in 1798. He was the British captain of the Hunter,a whaling ship. He called the island Pleasant Island.

   However,because it was very remote,Nauru had little communication with Europeans at first. Then whaling ships and other traders began to visit,bringing guns and alcohol. These elements destroyed the social balance of the twelve family groups on the island. A ten-year civil war started,which reduced the population from 1,400 to 900.

   Naum's real troubles began in 1899 when a British mining company discovered phosphate (憐酸鹽) on the island. In fact,it found that the island of Nauru was nearly all phosphate,which is a very important fertilizer for farming. The company began mining the phosphate.

    A phosphate mine is not a hole in the ground;it is a strip mine. When a company strip-mines,it removes the top layer of soil. Then it takes away the material it wants. Strip-mining totally destroys the land. Gradually,the lovely island of Nauru started to look like the moon.

In 1968,Nauru became one of the richest countries in the world. Every year the government received millions and millions of dollars for its phosphate.

   Unfortunately,the leaders invested the money unwisely and lost millions of dollars. In addition,they used millions more dollars for personal expenses. Some people realised that they had a terrible problem—their phosphate was running out. Ninety percent of their island was destroyed and they had nothing. By 2000,Nauru was almost financially mined. Experts say that it would take approximately $ 433,600,000 and more than 20 years to repair the island. This will probably never happen.

36. What might be the author's purpose in writing the text?

   A. To seek help for Naum's problems.

   B. To give a warning to other countries.

   C. To show the importance of money.

   D. To tell a heartbreaking story of a war.

37. What was Nauru like before the Europeans came?

   A. Rich and powerful.

   B. Modem and open.

   C. Peaceful and attractive.

   D. Greedy and aggressive.

38. The ecological disaster in Nauru resulted from

   A. soil pollution   B. phosphate overmining

   C. farming activity   D. whale hunting

39. Which of the following was a cause of Nauru^ financial problem?

   A. Its leaders misused the money.

   B. It spent too much repairing the island.

   C. Its phosphate mining cost much money.

   D. It lost millions of dollars in the civil war.

40. What can we learn about Nauru from the last paragraph?

   A. The ecological damage is difficult to repair.

   B. The leaders will take the experts’ words seriously.

   C. The island was abandoned by the Nauruans.

   D. The phosphate mines were destroyed.


    A special lecture began Thursday morning,given by a teacher aboard a space module about 340 km above her students on Earth,the first such attempt by Chinese.

   Female astronaut Wang Yaping,one of the three crew members of Shenzhou X spacecraft,greeted about 330 primary and middle school students at a Beijing high school,through a live video feed system. uHello,everyone. I am Wang Yaping. I will host the lecture today”> she said,smiling towards the camera,on board of the space module Tiangong I.

   The students on her class included children from migrant workers’ families,of ethnic minorities (少數(shù) 民族) and from Hong Kong,Macao and Taiwan. They were gathering at the High School Affiliated to Renmin University in Beijing. More than 60 million students and teachers at about 80 ,000 middle schools across the country were also watching the live broadcast on TV.

   The first section of the class was all about weight. Nie Haisheng,commander of the crew,made a bit show of crossing his legs into a meditation (沉思、) sitting posture in the air,which only a martial art (武術(shù)) master could do in the movies but was impossible for real people on Earth. Thanks to the weightless condition,we are all masters,M Wang joked.

   Then,Wang Yaping introduced the special scale on board of the orbiter,which was designed on basis of the Newton's second law of motion,or measuring the mass of an object through the net force and the acceleration.

    The lesson was aimed at making space more popular,as well as inspiring enthusiasm for the universe and science,according to Zhou Jianping,designer-in-chief of China manned space program,who added that the lesson would also accumulate experience for similar larger activities.

41. What's the best title for the passage?

   A. Chinese Astronaut Gives the First Space Lecture

   B. Students Watch Shenzhou X Spacecraft

   B. astronauts are experiencing weightless conditions when in space

   C. astronauts are showing to the students how they study and live in space

   These days,it can be difficult to find time for even the smallest of tasks. People are constantly on the go,and that stressful lifestyle can lead to all sorts of problems. Instead of living each day in chaos,follow these steps to manage your time and feel your best.

   Make the most of it.

   Try to kill two birds with one stone as often as possible. For example,if you have to take a day off from work to receive a delivery at home,schedule the appointment with the refrigerator repairman that youVe been putting off. The more you can check off your to-do list at once, .

   Just say no.

    Don’t try to please everyone by accepting every invitation for dinner or drinks. Politdy decline requests for your time if they interfere with precious family time or a work project you must finish. It will feel even better to reward yourself after you’ve completed several tasks.

Eat early or late.

   Instead of taking lunch at the usual noon hour,grab

a bite an hour earlier or an hour later. Then,youUl be able to get work done when the office is least crowded. Review your calendar.

   At the end of every month,take a look at the calendar. Note when you fell behind schedule and what days went smoothly. Then decide how many activities,meetings,and appointments you are realistically able to manage.

   Have self-awareness.

    Determine when you are at your best and brightest each day. Schedule your most difficult tasks for those times,to ensure you will be alert and awake for your toughest challenges.

55. What's the passage mainly about? (no more than 10 words)
