Q16 本题和上题属相同类型，解题点在”The first and the largest source is grants from the government.”，同样出现了典型论据的提示词the first。
        
        Q17 本文讲述了Heifer International组织从如何创立到其如何帮助发展中国家的农民；本题的解题点在”An American farmer, Dan West, developed the idea for Heifer International in the 1930s.”，考查Heifer International组织的创立人，heifer意思是小母牛。
        
        Q18 本题考查的是Heifer International的宗旨，在原文中间处：”They must also make a plan which will allow them to become self-supporting.”
        
        Q19 本题在做预读时可以得到的信息是they指代families，而且是得到帮助的家庭，故我们听力的重点是以families作主语的句子，本题考查言外之意，从原文中”Heifer International also believes that families must pass on some of their success to others in need.…Every family that receives a Heifer animal must agree to give that animal’s first female baby to other people in need . Families must also agree to pass on the skills and training they receive from Heifer International.”可以看到pass on sth. to sb.是这些话的关键点，意思是传递，必须将你获得的帮助也传递给其他需要帮助的人，故最后选择了”They should help other families the way they have been helped.”
        
        Q20 本题考查Heifer International取得的成就，在文章最后一句”This concept helps communities become self-supporting.”，跟本文开头的”One of the biggest problems in developing countries is hunger.”联系起来，不难看出，应该选择”It has helped relieve hunger in some developing countries.”。
