Give an example. B How do we get the word “secondary” from “second”? Secondary means “happen as a result of something else”. So, “secondary disasters” means “disasters happen as a result of other disasters”. For example, a big earthquake can cause a tsunami. We add “-ary” to the end of “second”. Read the passage quickly. Divide the passage into parts and summarise the main idea of each part. 2 Disasters are terrible. Sometimes, secondary disasters are even more dangerous because they create more damages. Secondary disasters include landslides, fires, floods, and so on. Here is a serious example. On March 11, 2011, the largest earthquake ever recorded in Japan caused great destruction. Tsunami waves hit the coastal area less than half an hour later. These waves damaged the Fukushima Daiichi nuclear power plant. In the following days, explosions occurred the plant. More than 150,000 people had to leave the area. Lots of radioactivity got into the ocean and came down from the atmosphere. The earthquake highlighted an important problem— disasters often cause a chain reaction, leading to more problems. If people do not deal with them properly, it will lead to greater disasters. It is everyone’s responsibility to take action to reduce disasters or secondary disasters. Part 1 Paragraph 1 The type and danger of secondary disasters. Part 2 Paragraphs 2-3 The earthquake in Japan leads to more problems. Part 3 Paragraph 4 Everyone should take actions to reduce disasters. Read the passage carefully and answer the questions. 3 1. How many secondary disasters are mentioned in this passage? What are they? 2. What disaster happened in Japan in 2011? 3. What happened to the Fukushima Daiichi nuclear power plant? 4. What should people do to reduce disasters? Five. They are landslides, fires, floods, tsunami and explosions (at the nuclear power plant). A big earthquake happened in Japan on March 11, 2011. It was damaged by tsunami waves, and explosions occurred there. Lots of radioactivity was released. People should take action to reduce disasters or secondary disasters. A Radioactivity got into the ocean and atmosphere. B Explosions occurred at the plant. C The largest earthquake in Japan caused serious destruction. D Tsunami waves hit the coastal area. C D B A Read the passage again and put the sentences in order. 4 Read the sentences and pay attention to the parts in yellow. 5 · Secondary disasters include landslides, fires, floods, and so on. · The earthquake highlighted an important problem. Compound words are formed when two or more words are combined. For example, land + slide = landslide, earth + quake = earthquake. Derivatives are created by adding affixes (prefixes or suffixes) to existing words. For example, second + -ary = secondary, harm + ful = harmful. 构词法(Word formation)： 合成和派生(Composition and derivation) 了解英语单词的构成规律，对我们记忆、使用单词都有帮助。合成法和派生法（加前缀、后缀)是很重要的两个英语构词方法。 一、合成词 合成词由两个或两个以上的词合并而成，又称为复合词。常见的合成方式如下表： 合成方式 类别 构成方法 例词 复合名词 名词 +名词 形容词+名词 副词 + 名词 名词+动词 coastline basketball highlight blackboard outdoor outside landslide earthquake 复合代词 代词宾格或物主代词+self(selves) some (any, no)+ one (body, thing) myself yourself himself herself ourselves themselves something somebody someone anything anybody anyone nothing nobody 二、派生词 派生词是指在一个单词的前面或后面加一个词缀而形成的新词。常见的前缀、后缀如下表： 前缀 前缀 构成方法 例词 un- 加在某些形容词前，构成其反义词 happy adj.—unhappy adj. important adj.—unimportant adj. dis- 加在某些动词、形容词或名词前，构成其反义词 appear v.—disappear v. honest adj.—dishonest adj. order n.—disorder n. en- 加在某些名词或形容词前构成及物动词 courage n.—encourage v. large adj.—enlarge v. rich adj.—enrich v. 后缀 后缀 构成方法 例词 -ment -ing -er -or -ion -tion 加在某些动词后，构成名词 develop v.—development n. meet v.—meeting n. teach v. —teacher n. act v.—actor n. discuss v.—discussion n. explain v.—explanation n. -al -ful -y -ly 加在某些名词后，构成形容词 coast n.—coastal adj. harm n.—harmful adj. wind n.—windy adj. friend n.—friendly adj. 后缀 后缀 构成方法 例词 -less 加在某些名词后，构成词义相反的形容词 care n.—careless adj. home n.—homeless adj. -ness 加在某些形容词后，构成名词 dark adj.—darkness n. happy adj.—happiness n. -ly 加在某些形容词后，构成副词 busy adj.—busily adv. clear adj.—clearly adv. Then circle more compound words in the passage. Disasters are terrible. Sometimes, secondary disasters are even more dangerous because they create more damages. Secondary disasters include landslides, fires, floods, and so on. Here is a serious example. On March 11, 2011, the largest earthquake ever recorded in Japan caused great destruction. Tsunami waves hit the coastal area less than half an hour later. These waves damaged the Fukushima Daiichi nuclear power plant. In the following days, explosions occurred the plant. More than 150,000 people had to leave the area. Lots of radioactivity got into the ocean and came down from the atmosphere. The earthquake highlighted an important problem— disasters often cause a chain reaction, leading to more problems. If people do not deal with them properly, it will lead to greater disasters. It is everyone’s responsibility to take action to reduce disasters or secondary disasters. Read the sentences and fill in the blanks. 6 A The second book in the series served as a secondary source of information for my research project.

Sometimes, secondary disasters are even more dangerous because they create more damages.有时，次生灾害甚至更危险，因为它们造成的损害更大。 Language points secondary adj. 次生的 second adv. 第二 常用搭配：secondary effects 次生影响 secondary disasters 次生灾害（如地震后的洪水、火灾） 例句：Earthquakes can cause secondary disasters like landslides. 地震可能引发滑坡之类的次生灾害。 例句：The fire started as a secondary effect of the gas explosion. 这场火灾是煤气爆炸的次生影响。 2. Tsunami waves hit the coastal area less than half an hour later.不到半小时后，海啸袭击了沿海地区。 less than 意为“少于”，后接具体数字、时间、数量等，强调“未达到某一数量”，其反义短语为more than, 意思是“超过”，相当于over。 例句：The project will take less than a week to finish. 完成这个项目只需不到一周的时间。 例句：There are less than 20 students in the classroom. 教室里的学生少于 20 人。 half an/a +名词，意为“半个……”。 half an hour 半个小时 half a day 半天 half an apple 半个苹果 3. If people do not deal with them properly, it will lead to greater disasters.如果人们不妥善处理它们，就会导致更大的灾难。 deal with“处理；处置”，deal with + 名词（问题、困难、人等），常与疑问副词how 连用。do with 意为“处理；处置”，常与疑问代词what 连用。 例句：The teacher helped me deal with the difficult math problem. 老师帮我解决了这道数学难题。 例句：How should I deal with these vegetables? =What should I do with these vegetables? 我 应该怎么处理这些蔬菜？ lead to 导致；通往 例句：All roads lead to Rome. 条条大路通罗马。 例句：Poor communication leads to misunderstandings. 沟通不畅会导致误解。 4. It is everyone’s responsibility to take action to reduce disasters or secondary disasters.每个人都有责任采取行动减少灾害或次生灾害。 这是一个主系表结构的简单句。It是形式主语；is是系动词；everyone’s responsibility是表语。to take action to reduce disasters or secondary disasters动词不定式短语是真正的主语，to reduce disasters or secondary disasters 是另一个动词不定式短语，作目的状语。 take action 采取行动；采取措施 take action to do sth. 采取行动做某事 例句：We should ‌take action to protect‌ endangered species. 我们应该采取行动保护濒危物种。 Practice 根据句意及提示完成下列句子 1.
