【正确答案】 D

【答案解析】[听力原文]
Our eating habits are very important for good health and a strong body. There are times when most of us would rather eat sweets and ice cream than meat and rice. Sweets and ice cream are not bad for the stomach if we eat them at the end of a meal. If we eat them before a meal, they may take away our appetite. It is important for us to eat our meal at the same time each day. When we feel hungry, it is a sign that our bodies need food. When we feel angry or excited, we may not want to eat. When we are worried, we may not want to eat, either.
A long time ago, in England, some judges used to decide whether a man was telling the truth by giving him some dry bread. If the man could not swallow the bread, it was a sign that he wasn"t telling the truth. He was telling a lie. Although this seems very strange and rather foolish, it is indeed an excellent way of finding out the truth. A man who is worrying about something has difficulty in swallowing anything dry. Because when he is worrying, he loses his appetite and does not want to eat.

Which of the following may take away our appetite before we have our meal?

[解析] 四个选项均是食物，在听音的过程中若听到了选项中的词，则要在选项旁稍做记录。文章主要讲的是饮食习惯与健康的问题。文中提到，饭前吃sweets and ice cream会影响胃口，D将其中的sweets换成了同义词candy。故选D。A在文中提到了，但与本题的提问无关，故排除；B中的butter和C在文中均未提及。本题也可从另一种角度来解答：根据生活常识，A、B、C都有可能是正餐的内容；只有D属于零食范畴，若在饭前食用容易影响胃口。故可判断D正确。

【正确答案】 B

When had we better have our meals?

[解析] 四个选项描述的都是时间。文中提到，每天在同一时间吃饭很重要。选项B中的at regular intervals就是文中at me same time的同义表达，所以B正确。A、C在文中均未提及；D在文中虽有提及，但不是吃饭时间的建议，只是表明我们的身体需要食物。此外，本题也可依据生活常识轻松地选出正确答案B。

【正确答案】 D

How could the judges in old England tell that a man had told a lie?

[解析] 预读选项时要注意辨别各选项间的异同。文章的后半部分讲了很久以前英格兰法官判断嫌疑人是否说谎的方法：给他吃干面包。吃不下就是说谎了，因为人在不安的时候难以咽下任何干的食物。故选D。英语的习惯是先说结果，再说原因。文中也是先说法官的做法，然后解释为什么他们会这样做。A、B表达的均是肯定含义，与文中的否定含义(如could not，has difficulty等)相违背，故可同时排除；C在文中未提及。
