Lesson 28: The Study of Living Things
I. Learning aims:
Master the new words:
Chip Taylor, biology, butterfly, migrate, fantastic, completely,
grandchild, female, milkweed, chemical, puzzling
II. Learning important and difficult points:
1) Fantastic fac ts about the butterfly have been drawing Dr. Taylor’s attention.
2) Here, as many as 230 million butterflies spend the winter.
3) But in Mexico, people cut down the trees that the butterflies need
to rest on because they want more land for farming.
4) This is both puzzling and interesting for many scientists.
Language Points:
1. fantastic
【用法】作形容词，意为“奇异的、极好的、了不起的”，在句中
作定语或表语。
【举例】①I think this is a fantastic invention. 我想这是一个了不
起的发明。
②These flowers are so fantastic. They have many different
colours. 这种花太奇异了。
它们有很多不同的颜色。
2. chemical
【用法】作可数名词，意为“化学物质、化学制品”，复数形式是
chemicals。
【举例】There are no chemicals in this kind of food. 这种食品中没有化学物质。
【用法】作形容词，意为“化学的、化学作用的”，在句中作表语或定语。
【举例】We can find chemical additives in many foods. 我们在很多食品中发现了化学添加剂。
3. Fantastic facts about the butterfly have been drawing Dr.
attention. 这些有关蝴蝶的奇异的事实引起了泰勒先生的注Taylor’s
意。
【用法】句中的have been drawing 是现在完成进行时，它由“助动词have (has) + been + 现在分词”构成，当主语是第三人称单数时
用助动词has，其他情况用助动词have。
现在完成进行时主要表示从
过去开始一直持续到现在的动作，这个动作是否延续下去，要根据上下文而定。
它往往与表示一段时间的时间状语连用，如：all the time, this month, all day, these few days, for a year, since a week ago等。
【举例】①She has been playing basketball after school this week. 这个星期她放学后一直打篮球。
②Tony has been drawing in his bedroom all the afternoon. 托尼在卧室画了一下午。
4. This is both puzzling and interesting for many scientists. 对很多科学家来说这既令人费解又很有趣。
【用法】连词both…and…的意思是“……和……都，既……
也……”，它可以连接句中句子成分相同的词语，如果用它连接主语时，谓语动词要用复数形式。
【举例】①She likes both sports and music. 她既喜欢运动，又喜欢音乐。
②Both Li Ping and her mother take exercise every morning. 李萍和她妈妈每天早晨都进行锻炼。
