(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;一類是確定文章標題或主題(topic / title / headline)型;還有一類是詢問文章的寫作目的(purpose)。

　　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。主題句呈現形式通常有以下幾種：

　　1)在開頭出現;

　　2)在結尾出現;

　　3)在開頭和結尾同時出現，首尾呼應;

　　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出來，這就要求學生學會歸納概括。

　　(三)實戰演練

　　However, today, more and more consumers are choosing “green” and demanding that the products they buy should be safe for the environment. Before they buy a product, they ask questions like these, “Will this shampoo damage the environment?” “Can this metal container be reused or can it only be used once?”

　　A recent study showed that two out of five adults now consider the environmental safety of a product before they buy it, this means that companies must now changed the way they make and sell their products to make sure that they are “green”, that is, friendly to the environment.

　　Only a few years ago, it was impossible to find green products in supermarkets, but now there are hundreds. Some supermarket products carry labels (標簽) to show that the product is green. Some companies have made the manufacturing (生產) of clean and safe products their main selling point and emphasize it in their advertising.

　　The concern for a safer and cleaner environment is making companies rethink how they do business. No longer will the pubic accept the old attitude of “buy it, use it , throw it away, and forget it.” The public pressure is on , and gradually business is cleaning up its act.
