课时作业20Ⅰ.阅读理解Wheat is a main source of food for people across the planet, accounting for a fifth of the calories consumed globally.But as a result of climate change, scientists believe most parts of the world where the crop is grown will be hit by water shortages by the end of the century.And the US could be among the countries worst affected, the authors of the research published in the journal Science Advances told Newsweek.If climate change isn't dealt with, by the year 2100,60 percent of areas that grow wheat will be hit by water scarcity—up from the current level of 15 percent, according to the international team of scientists.Coauthors Miroslav Trnka and Song Feng told Newsweek that in their previous research, they had shown climate change may cause soil to become less moist(湿润的) across most mainland US states, including those where wheat is grown.As a result, the US could be “one of the top most affected wheat producers” in terms of the increase in areas affected by severe droughts，they said in a joint statement.Worryingly, existing research has predicted a 4.0 to 6.5 percent drop in global wheat production per 1 degree Celsius of warming if climate change isn't eased.And it's unlikely that wheat can be replaced if water becomes scarce, as it's not as thirsty as other crops and can do without water for a relatively long period of time.“If multiple regions are affected by drought at the same time，it might be difficult to meet the demand even if the trade routes stay open and are not restricted by governmental measures，” warned Feng and Trnka.However，he said，“Studies show that if we continuously improve the sustainability and technologies in the coming decades and allow for international trade, we may overcome the negative impacts of climate change.”文章大意：科学家认为由于气候变化，到本世纪末，世界上大部分种植小麦的地区将受到缺水的影响，如果气候变化不得到缓解，全球小麦的产量将会减少。

AVenice, a small waterside city in northeast Italy, boils with happiness and excitement once every year. Between February 21 and March 4, carnival (狂欢节) hits the streets.For most people carnival means large parties and feasting. But in Venice, it also means traditional masks and costumes.These costumes were originally meant to hide personal identities. Then, different social classes could mix in a sea of happiness. Along the waterway, people greeted each other with “Good morning, Mrs. Mask！”Today, people in Venice still dress up in the strangest ways —as armed soldiers, butchers and fishermen, for example.Bars and cafes are filled with partygoers who e to show off their fancy costumes. Their designs and creations are made by special studios. Readymade costumes are not acceptable.“In the months before the carnival we work overtime to meet the demand，”said a maskmaker. “Many kilometers of silk and lace are made into costumes. For shopkeepers, carnival is the best time of year.”The Venice carnival dates back to the Middle Ages. At that time, the city was one of the wealthiest in Europe.The tradition of celebrating with masks and costumes is thought to have been started by the “Stocking panies”. These were groups of young men who organized parties and festivals and wore colorful stockings to distinguish_themselves.By the 18th century，the carnival had reached its peak. It all came to an endwhen Napoleon conquered (征服) Venice in 1797.But in 1979, local people brought the old tradition back to life.Now the Venice carnival attracts huge crowds from all over the world. This year, about 700,000 people are taking part in. Hotels were fully booked months in advance, bars and restaurants overflow every day.The city certainly benefits —a whole industry has been built up around the carnival's masks and costumes. “The Venice carnival is a magical time! It's such a great experience，”said one French tourist.1．During the carnival ________.A．students of all ages also join in the activitiesB．people want to be dressed in the most beautiful clothesC．people in the costumes and masks want to make others think they are rich D．people dressed in the strangest ways don't want to be recognized2．That people at the carnival were greeted “Mrs. Mask！”shows that ________.A．all the people at the carnival were women at one timeB．all the people at the carnival wore masksC．people weren't able to tell men from women at the carnivalD．people at the carnival don't know each other3．What does the underlined expression “distinguish themselves”most possibly mean?A．To make themselves up.B．To make themselves different.C．To warm themselves up.D．To recognize themselves.【语篇解读】本文介绍了威尼斯狂欢节的特点。
