【文章內(nèi)容簡介】 ses like malaria and HIV, are illequipped to deal with obesityrelated illness like heart disease and diabetes. Pacific islands have the highest obesity rates in the world, due to the spread of western fast food. Diets which a generation ago largely consisted of fish and coconuts are now mainly made up of processed meat. Nauru is top on the list, 61% of the population is overfat, making this tiny paradise island the world’s fattest nation. Cook Islands take second place, with an obesity rate of 56% and Marshall Islands e in third, with 53%. The Middle East is also facing an obesity crisis. In Saudi Arabia, Qatar and Kuwait, more than a third of the population is overweight. Obesity is already a global epidemic and is rapidly spreading from the rich world to the poor. 28. What do we know about BMI according to Paragraph 2? A. Diabetes and heart disease are caused by BMI. B. Anyone with BMI over 30 is considered overfat. C. BMI is the greatest risk faced by the developing countries. D. People with BMI over 30 will develop weightrelated diseases. 29. According to the passage, obesity in Africa is caused by ________. A. its terrible shortage of food B. its suffering from the famine C. the challenges of diseases like Malaria and HIV D. its shift from traditional food to highcalorie fast food 30. It can be inferred that people on the Pacific Islands ________. A. try to avoid the processed meat B. used to have healthier diets C. suffer from undernourishment D. prefer fast foods to fish and coconut 31. What is the best title of the passage? A. Obesity: Not Just a RichWorld Problem B. BMI: Index of Your Body Mass C. Fast Foods: Main Cause of Obesity D. Diabetes: ObesityRelated Illness D A new study says a widelyused insecticide（殺蟲劑） is damaging wild bee populations. Wild bees are important, because they pollinate（給??授粉） crops and wild plants. Environmentalists in the United States and Europe say chemicals called neonicotinoids（新煙堿） are causing a drop in the number of bees. Farmers often use seeds treated with these chemicals. The chemicals target insects that eat crops, and they do not spread beyond the field. But they do get into pollen（花粉） , which is where the bees e into contact with them. Maj Rudlof is a researcher at Lund University in Sweden who led the neonicotinoids study. She and other researchers studied bees in fields. Half of the fields were grown with seeds treated with neonicotinoids. The other half was grown with seeds that were not treated. “The most impres sive result we found was that bumblebee settlement almost didn’t grow at all at the treated sites in parison with the controlled sites.” She says there were about half as many wild bees per square meter in treated fields as in untreated ones. Dennis vanEngelsdorp, a scientist who studies insects, works at the University of Maryland. He was not involved with the research on neonicotinoids. But he says banning the chemicals may not be the answer. He says they are not as bad as other insecticides. “In many cases, neonicotinoids are actually the safest alternative. So by banning it, what you’re doing is forcing farmers to use products that may either be just as bad or worse.” He says farmers often use the chemicals too much, and that may be hurting bees. Mr. vanEngelsdorp thinks farmers might not need to stop using neonicotinoids pletely. He suggested that the chemicals should be used only when necessary. A United States Department of Agriculture report included information about the effects of neonicotinoids. It says the chemicals make the bees more likely to bee sick. The bees cannot fight the viruses that monly affect them. 32. The wild bees get poisoned with the chemicals because ________. A. they feed on the insects that eat the crops B. they eat the seeds treated with these chemicals C. they land on the pollen containing such chemicals D. they cannot tell where the chemicals have been spread 33. What happened in the fields where seeds were treated with neonicotinoids? A. Almost no crops grew in the fields. B. The bumblebees almost didn’t grow. C. There was an increase in the number of the bumblebee. D. There were about 50% less wild bees than in untreated sites. 34. Dennis vanEnglesdorp believes that neonicotinoids ________. A. do not hurt the bees B. have safer alternatives C. must be banned pletely D. should be used only when needed 35. The underlined word “them” in Paragraph 5 refers to ________. A. the chemicals B. the neonicotinoids C. the bees D. the viruses 第二節(jié) （共 5小題 ；每小題 2分，滿分 10 分） 根據(jù)短文內(nèi)容，從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項為多
