　　主要考查對文章進(jìn)行概括或總結(jié)的能力，要求在閱讀短文時，能夠提煉文章的中心思想，體會作者的主要寫作意圖，充分運(yùn)用邏輯概括能力，透過字里行間獲取文章最具代表性的觀點、論點及作者的情感傾向。

　　(一)出題形式：主旨大意題命題形式主要有三大類：一類是概括中心思想(main idea)型;一類是確定文章標(biāo)題或主題(topic / title / headline)型;還有一類是詢問文章的寫作目的(purpose)。

　　1) What would be the best title for the text?

　　2) What is the topic of the text?

　　3) Which of the following best expresses the main idea?

　　4) The best title / headline for this passage might be ______.

　　5) The author s main purpose in writing the passage is ______.

　　6) Which of the following statements is best supported by the text?

　　7) Which of the following best summarizes the passage?

　　8) The main idea / The general idea / The main theme of this passage is ______.

　　9) The title that best expresses the main idea of the passage is ______.

　　(二)答案位置：大部分文章都有主題句(topic sentence)，主題句表達(dá)了文章的中心思想(main idea)，找到了主題句，也就抓住了文章的主旨大意。因此， 主題句定位法 是解答主旨大意題的一種行之有效的方法。主題句呈現(xiàn)形式通常有以下幾種：

　　1)在開頭出現(xiàn);

　　2)在結(jié)尾出現(xiàn);

　　3)在開頭和結(jié)尾同時出現(xiàn)，首尾呼應(yīng);

　　4)有些文章的中心思想貫穿全文，并沒有用一句話明確表達(dá)出來，這就要求學(xué)生學(xué)會歸納概括。

　　(三)實戰(zhàn)演練

　　26 All of us eat every day, but most of us don t understand nutrition. How much do you know about good nutrition? Are the following statements true or false?

　　1. People who don t eat meat can stay healthy.

　　True. As long as people eat enough milk, eggs and meat alternated, they can get enough protein.

　　2. Fresh vegetables cooked at home are always more nutritious than canned vegetables.

　　3 Food eaten between meals can be just as good for health as food eaten at regular meals.

　　True. Nutritional value depends on what type of food you eat, not when you eat them. Eating an egg or an orange between meals can contribute to a good diet.

　　4. Taking extra vitamins beyond the recommended daily allowances won t give you more energy.

　　True. It s widely believed that extra vitamins provide more energy. But taking more than the body needs doesn t make it function better, not more than overfilling your gas tank makes your car run better.

　　5. Natural vitamins are better supplements for the diet than synthetic vitamins.

　　False. There is no difference. A vitamin has the same properties and specific chemical structure whether made in a laboratory or taken from plant or animal parts.

　　6 Older people need the same amount of vitamins as younger people.

　　True. Older people need the same amount of vitamins as younger people although they need fewer calories . Certain illnesses raise the requirements for some vitamins, but that is true for the young as well as the old.

　　7 Food grow in poor soil is lower in vitamins than food grown in rich soil.

　　False. The vitamins in our food are made by the plants themselves. They don t come from the soil. However, the minerals in a plant depend on the minerals in the soil.

　　If you have answered these questions correctly, You can say you know much about food and nutrition by today s standards. But remember that nutrition is growing science and that it may be changed as new information is obtained.

　　The main purpose of the passage is _____.

　　A to list today s standards of food and nutrition
