2
this is the Agriculture Report.
3
Irrigation systems can make a big difference in agricultural production.
4
Irrigation can also improve the lives of farm families.
5
However, a new study says bringing water to dry areas can also spread malaria.
6
The study describes how irrigation water can lead to an increase in malaria cases,
7
an increase that can last for years.
8
Malaria is spread by mosquitoes.
9
The insects reproduce in standing water.
10
So when a dry area is irrigated,
11
the disease can appear and spread.
12
Mercedes Pasquale is a scientist at the University of Michigan.
13
She and her team studied areas in northern India where irrigation systems were built over a number of years.
14
They compared how malaria progressed with the spread of irrigation.
15
She and the other scientists found that after farmers began irrigating their crops,
16
the risk of malaria rose sharply.
17
At first, the team thought the number of cases rose because there was little effort to control mosquitoes.
18
But the study found that was not the case.
19
The researchers found that high rates of malaria continued for 10 years or longer,
20
even after mosquito control efforts were in place.
21
Mercedes-Pasquale suggests that irrigation projects need to limit places where mosquitoes might reproduce.
22
She also says health officials may need to try other methods of malaria prevention that would work for long periods of time.
23
The researchers agree that irrigation helps farming in areas with low rainfall.
24
But Mercedes-Pasquale and her team discovered that irrigation also can bring years of high rates of malaria.
25
The only way to avoid the problem is through better planning and control measures.

什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
