Some feel that they haven't eaten a meal unless they have had steak or other red meat. Some prefer chicken or fish and eat one or the other at every meal. Others prefer vegetables and fruits or grains and would enjoy a meal of spaghetti, eggplant, and fresh fruit. Others could live on what were called fast--foods: a hamburger or hot dog, French fries and a soft drink. ‎ ‎（1）主题句在段首：一个主题句常常是一个段落的开头，其后的句子则是论证性细节。在论说文，科技文献和新闻报道中多采用这种格式。 ‎ Sample 2‎ Some students prefer a strict teacher who tells them exactly what to do. Others prefer to be left to work on their own. Still others like a democratic discussion type of class. No one teaching method can be devised to satisfy all students at the same time. ‎ ‎（2）主题句也会出现在段尾。作者先摆出事实依据, 层层推理论证, 最后自然得出结论, 即段落的主题。本段的中心思想在结尾句得到体现,它是此段内容的结论。 ‎ Sample 3‎ Nothing is as useful as a flashlight on a dark night if a tire goes flat. Few inventions are so helpful to a child who is afraid of the dark. In fact, the modern flashlight brings light to many dark situations. Finding something in the back of a closet is easy with a flashlight in hand . A camper also needs one after the light of the campfire has been out.‎ ‎（3）主题句在短文中间：当主题句被安排在段中间时, 通常前面只提出问题，文中的主题由随之陈述的细节或合乎逻辑的引申在文中导出, 而后又作进一步的解释, 支撑或发展.‎ ‎（三）推理题 ‎1. 推理题的出题方式常常包括以下类型：‎ ‎1) It can be inferred from the text that ______. ‎2) From the text we know that ______. ‎3) The story implies that ______. ‎4) The paragraph following the passage will most probably be ___.‎ ‎5) The writer’s attitude toward...is ______. ‎6)The author implied（suggested）that．．． ‎ ‎7)It may be concluded from the passage that．．． ‎ ‎8)Which of the following statements does the passage support？ ‎ ‎9)With which of the following does the author agree？ ‎ ‎2. 解推断题应注意： ‎(1)不能以自己的观点代替作者的观点； ‎(2)推理的根据来自于上下文。 ‎ ‎3. 解推断题的方法：根据词义关系推断具体细节。‎ Sample1：‎ ‎“You mean there is no baby who is dying?” said De Vincenzo.‎ ‎“That’s right,” said the official.‎ ‎“That’s the best good news I’ve heard all week.”said De Vincenzo.‎ Q: I t can be inferred that what worried De Vincenzo most was______________.‎ A. the poor woman B.the official’s advice C.the winning check D.the baby’s life Sample2:‎ ‎ One day a man walked into a pet shop and said to the shop assistant, “I need two small mice and about five dozen roaches (蟑螂) and two spiders.” ‎ “What do you need these things for?” the shop assistant was very surprised.‎ ‎ “Well,”replied the man，“I’m moving out of my apartment and the landlord insists that I should leave the house in exactly the same condition as I found it.”‎ Q： The passage suggests that when the writer moved into the house, it was ______.‎ ‎　　A. very clean B. just cleaned by the landlord ‎　　C. tidy and comfortable  D. dirty and full of insects ‎（四）观点态度题 ‎1. 考查作者观点态度的提问方式有：‎ ‎1)The author seems to think that ______. 2)The writer is trying to present a point of view in ______. 3)The author wants to appeal to _______ . 4)The author’s style is ______ . 5)The author’s tone would be best described as _______ . 6)What is the author’s opinion of ______?‎ ‎7)The writer believes that________?‎ ‎8) In the author's opinion_________? ‎ ‎2. 确定作者态度，可以有两种思路：‎ ‎1）问全文主体事物的(包括主题)，可以根据阐述主题或有关主体事物的相关句中的形容词、副词或动词确定作者的态度；‎ ‎2）如果问的是对某一具体事物的态度，则可以定位到具体相关句，然后确定答案。 ‎ Sample 1 ‎ ‎ Some people are never right. They never have good luck. They usually do the wrong thing and say the wrong thing. And even if what they say or do is OK，they as a rule say it or do it at the wrong time. So these people always have problems. They often break dishes. They sometimes miss buses and airplanes.‎ ‎ Mr. Neff is different. He is always right. He is never wrong. He usually has good luck. He seldom has problems. He never breaks dishes. He never misses buses or airplanes. Even if he does miss them，it is always the fault of the buses or air planes. Mr. Neff knows almost everything.

He finds Mr. Neff hard to understand. B. He thinks Mr. Neff wonderful. ‎ C. He feels pity for Mr. Neff. D.

The relationship develops until the two partners cannot manage without each other. This is so in corals(珊瑚) of the sea. In their skins, corals have tiny plants which act as "dustmen", taking some of the waste products from the coral and giving in return oxygen which the animal needs very much to breathe.‎ ‎3．语法分析法是准确理解细节的有效方法 当堂导练二：‎ ‎1. 主旨大意题：‎ ‎ Federal regulators Wednesday approved a plan to create a nationwide emergency alert （警报） system using text messages delivered to cell phones.‎ ‎　　Text messages have been popular in recent years, particularly among young people. The wireless industry's trade association, CTIA, estimates（估计） more than 48 billion text messages are sent each month.‎ ‎　　The plan comes from the Warning Alert and Response Network Act, a 2006 federal law that requires improvements to the nation's emergency alert system. The act tasked the Federal Communications Commission （FCC） with coming up with new ways to alert the public about emergencies.‎ ‎　　“The ability to deliver accurate and timely warnings and alerts through cell phones and other mobile services is an important next step in our efforts to help ensure that the American public has the information they need to take action to protect themselves and their families before, and during, disasters and other emergencies,” FCC Chairman Kevin Martin said, following approval of the plan.‎ ‎　　Participation in the alert system by carriers -telecommunications companies is voluntary, but it has received support from the wireless industry.‎ ‎　　The program would be optional for cell phone users. They also may not be charged for receiving alerts.‎ ‎　　There would be three different types of messages, according to the rules.‎ ‎　　The first would be a national alert from the president, likely involving a natural disaster. The second would involve “approaching threats”, which could include natural disasters like hurricanes or storms or even university shootings. The third would be for child abduction （绑架） emergencies, or so-called Amber Alerts.‎ ‎　　The service could be in place by 2010.（ 2008年高考英语山东卷B篇）‎ ‎　　66. Which of the following would be the best title for the text？‎ ‎　　A. Cell Phone Alerts Protecting Students ‎　　B. Cell Phone Alerts by Wireless Industry ‎　　C. Cell Phone Alerts of National Disasters D. Cell Phone Alerts Coming Soon 答案：D ‎2. 猜测词义题 Weeks later, standing before this unfriendly mass, I was totally lost. Oh well, I lowered the paper and sat down at my desk， burning to find out what I had done wrong. As a classmate began his report, it all became clear, “My report is on George Washington, the man who started the American Revolution.” The whole world became quite! How could I know that she meant that George Washington?‎ 62. The underlined word “burning” in Para. 3 probably means _______.（2012年北京，B篇，62，答案D）‎ A. annoyed B. ashamed C. ready D. eager 解析：从burning这个词来说，意为“发热的，强烈的，燃烧的”，后面紧跟动词词组“find out”说明在寻找时刻的心情是很紧张和急迫的，最后是一个宾语从句，是我曾经做错过什么，那么这个题目显然就是选择和“渴望的，热切的”词义，显然为D选项。‎ 3. 细节理解题 Life on Land ‎ Life on land probably began about 430 million years ago, though it has existed in the water for perhaps as long as 3000 million years. When we think of the first life on land, we probably think of strange animals coming out of the oceans, but, in fact ,no animals could have been living if plants had not been on land first. Plants had to be on land before animals arrived. They supplied the first land animals with the surrounding and food necessary, since they--the plants are the only form of life that is able to get and store energy.‎ ‎ The first plants to exist out of the water were probably certain kinds of algae (海藻) which were followed by other plants that grew close to the ground and needed water in which to reproduce.‎ Which of the following is TRUE?‎ A. Algae have existed for more than 430 million years.‎ B. It is impossible that algae might be the earliest plant on land.‎ C. Plants get food from animals in the oceans.‎ D. Evolution began after animals appeared on land.‎ After class:‎ Step5: 自辅落实 Try to finish two reading passages using the reading skills you have learnt.‎
