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 News week.
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.
Co authors 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.”
1.How will climate change hurt wheat production
A.By lowering the temperature.
B.By reducing the water supply.
C.By polluting the soil.
D.By flooding the field.
2.What can we learn from Paragraph 3
A.Wheat production caused droughts in most mainland US states.
B.The United States is the biggest wheat producer in the world.
C.The United States will suffer a lot from climate change.
D.Climate change is closely watched by American scientists.
3.Why is wheat unlikely to be replaced by other crops in a drought
A.It is the primary food for most countries.
B.It is not influenced by global warming.
C.It is widely grown in most countries.
D.It needs less water than other crops.
4.In which section of a newspaper may this text appear
A.Health.
B.Science.
C.Education.
D.Entertainment.

Fisherman Salvador was just trying to make a living on the sea with fellow fisherman Cordoba.Two days into the journey,disaster struck,and the two men would begin the greatest challenge of their lives.
The boat was loaded with tons of provisions,including 70 gallons of gasoline,16 gallons of water,50 lbs of sardines for bait(鱼饵).They also had a mobile phone,kept safe in a plastic bag,a GPS,and a two?way radio.The two had never spoken before or worked together,but they liked fishing and both of them seemed to know what they were doing.
Two days later,the weather was getting worse and worse.Salvador was trying to remain calm,but Cordoba was not prepared.He held on to the rail(围栏) for dear life as the waves crashed around them,vomiting and crying.When the storm finally passed,Salvador could finally see in front of him; he noticed that they had drifted far away from land.To make matters worse,the motor had stopped working.Salvador called his boss on the radio,but there was no response.Even worse was the fact that the GPS they had brought with them had stopped working.
The two men had been at sea for two months.While Salvador had become accustomed to catching and eating the animals available to them,Cordoba's mental health and physical health had begun to decline.Once he got sick from eating raw seabirds,he refused to eat at all.His own depression,fear and malnutrition finally killed him,leaving Salvador alone on the boat.
One day,after a terrible storm,Salvador found the sky was suddenly filled with shorebirds.He knew that he was heading for land at last.He must have been close.There,in the distance was a green Pacific atoll(环礁).It looked small and wild,but it was a dry land and would likely have food and shelter.
Paragraph 1:
The skinny fisherman struggled until he reached what appeared to be a beach house.
Paragraph 2:
Salvador was rescued.
