(原创)Suffering from malnutrition(营养不良), Regelyn often felt tired and sometimes didn’t want to attend school. Some classmates even laughed at her because of her extremely thin frame.With a limited income selling boiled corn, Regelyn’s parents had difficulty providing food for her and her four sisters and brothers. Thanks to the healthy meals she received through the nutrition program, Regelyn returned to a normal weight.When she was 10 years old, she graduated from the Children International nutrition improvement program. “I feel very happy because now I am strong ...”reports a now­healthy teenaged Regelyn.Regelyn’s mother, Arlenda, received nutrition education on planning a balanced diet and cooking simple but nutritious meals. While the family may still struggle to afford decent(相当好的)food, Arlenda hopes she can better use the family’s income to provide enough healthy food. “We are not asking for delicious meals every day, but just nutritious food enough to feed all seven of us three times a day，” Arlenda explained.Regelyn and her family are not alone. Around the world, countless families continue to feel the pain of hunger. Regular financial contributions to Children International help offer money to important programs that give children like Regelyn chances to have the basic essentials of life — essentials they might never have if there are no such programs.1.

Unit 4 Global warmingⅠ.阅读理解A体裁：说明文话题：天气词数：303 时间：6′Droughts(干旱) caused by global climate change have led to a drop in wheat production，a worldwide shortage and high food prices around the world.The global wheat supply is at its lowest point in 50 years，with only an estimated 10 weeks of supply left.This has been one factor pushing the prices of bread，beer and other wheat－containing foods steadily higher.According to Hilton Dinner，a bakery owner from Edmonton，Canada，the price of flour has more than doubled over the past eight months.In 19 years of business，Dinner said，he has never seen prices rise like this.“Prices creep up seasonably，” he said.“They might go up 10 percent，then down 5 percent.They never go back to where they started，but they creep.This is not creeping，this is drastic.”Also to blame for the global wheat shortage is the rising population，coupled with increasing meat consumption worldwide.This has led to the increasing diversion of grain to animal feed.Analysts anticipate that the shortage may be resolved within 12 months，as farmers pull fallow land into wheat production.But even when the shortage resolves，food prices are only expected to keep climbing due to other factors，such as high energy and shipping costs.“It's not something that's going to go away，” Dinner said.“Food in general is going to go up.As wheat goes up，so does the price of eggs and chicken because they eat grain－based feed.It affects people who can't afford to pay more for their food.”Public health experts have expressed concern about the effect that rising food prices have on the poor.The United Nations recently reported that in 2007，the cost of food imports in the world's neediest countries increased 24 percent，to a total of $107 billion.【语篇解读】气候变化引起干旱，干旱又引起小麦产量的下降，产量下降又引起小麦价格的上涨。

【关键字】英语Unit 4 Global warmingⅠ.阅读理解A(2016·上海)Is there link between humans and climate change or not? This question was first studied in the early 1900s.Since then, many scientists have thought that our actions do make a difference.In 1997, the Kyoto Protocol explained our role in the Earth's changing atmosphere and set international limits for gas emissions(排放) from 2008 to 2012.Some countries have decided to continue these reductions until 2020.More recently, the Paris Agreement, stuck by nearly 200 countries, also aims to limit global warming.But just now how much warmer it will get depends on how deeply countries cut carbon emissions.——This is how much temperatures would rise by 2100 even if nations live up to the initial Paris promises to reduce carbon emissions; this rise could still put coastal cities under water and drive over half of all species to extinction.——To meet this minimum goal, the Agreement requires countries to tighten emissions targets every five years.Even this increase could sink some islands, worse drought(干旱) and drive a decline of up to a third in the number of species.——This is the most ambitious goal for temperature rise set by the Paris Agreement, after a push by low-lying island nations like Kiribati, which say limiting temperature rise to could save them from sinking.——This is how much temperatures have risen since the industrial age began, putting us 40% of the way to the point.——The baseline here is average global temperature before the start of the industrial age.文章大意：本文介绍了人们一直努力减少温室气体的排放，并设立了到2100年我们应该达成的目标以及达成目标要符合的条件。

课时提升作业二十九选修6Unit 4Global warming(限时35分钟)Ⅰ. 阅读理解AThe researchers’ findings will hardly come as a surprise to those who study air pollution. Previous research has shown that outdoor air pollution causes more than 3 million deaths annually and suggested that the figure could double by 2050.Another study suggested that air pollution causes 1. 6million premature(早产儿)deaths annually in China alone.Policy makers across the globe have responded to airpollution with a number of new regulations, many ofwhich focus on limiting pollution from coal. China stopped approval of new coal mines for three years at the end of 2019 and has issued strict requirements along the lines of those in the U. S. for new coal-fired power plants. Cities in China have also developed warning systems to get cars off the streets and limit industrial pollution during periods of intense smog. But even these policies may still be met by increases in mortality (死亡率)as aging populations are increasingly suffering from the problems associated with pollution.“China might move in the right direction in terms of air pollution,but it’s going to have to continue revising policies just like the U. S. and Europe, ” said Dan Greenbaum, president of Health Effects Institute, which supported the research.And, while premature deaths due to pollution in the U. S. and Europe have declined in recent decades, cities in the West have still taken steps to reduce pollution. Air pollution kills more than 200, 000 in Europe and nearly 80, 000 in the U. S. each year, according to the research. The benefits of addressing air pollution extend beyond the people who experience the health effects of poor air directly.“One of the unique things about air pollution is that you can’t run, you can’t hide from it, ” said study researcher Michael Brauer, a professor at the University of British Columbia, in a video accompanying the presentation. “But we know that if you improve air quality, everybody benefits from it. ”【文章大意】本文是一篇新闻报道。
