這種題目有一定難度，往往不能直接從文中找到答案，而必須根據(jù)上下文及其相互間的關(guān)系或?qū)φ�篇文章進(jìn)行深層理解后，才能找到答案。有時(shí)甚至還得聯(lián)系作者的意圖、態(tài)度等弦外之音、文外之意加以推理，才能獲得正確答案。應(yīng)從情節(jié)所提供的基本事實(shí)出發(fā)，尋找一定規(guī)律，如：時(shí)間關(guān)系、條件關(guān)系、因果關(guān)系、比較關(guān)系、轉(zhuǎn)折關(guān)系等作為推理根據(jù)。

　　下面我們一起來看一篇文章，希望你先做完然后再看分析。 Passage 1

　　Are you carrying too much on your back at school? You’re not alone. Back experts in the United States are worried that young students are having back and neck problems as a result of carrying too much in their backpacks (schoolbags).

　　“It hurts my back when I run,” said Oberlin Reyes, a student in Virginia. “It’s hard to get up the stairs with my backpack, because it’s too heavy.”

　　Oberlin is among students whose backpacks were weighed for a week in a recent study.

　　They had regular backpacks with two straps (帶子) to carry them, but a number of students with heavy loads had switched to rolling backpacks (which have wheels and can roll on the ground).

　　Shirley Park, whose backpack weighed 10 kilograms, said she changed to a rolling backpack because she was starting to have back pain.

　　How much is too much? Experts say students should carry no more than 10 to 15 percent of their own body weight.

　　A few students had one suggestion to lighten the load: less homework.

　　P.S. (附) Doctor’s suggestion:

　�、� Lighten the load. Clean out binders (活頁材料) and take home only the books you need that night.

　�、� Wide straps are better. They send out the weight over your shoulders more evenly (均勻). And be sure to wear both straps rather than hanging the pack over one shoulder.

　　③ Pack smart. The heavier things should be packed closed to the back.

　�、� Bend both knees when you pick up the pack, and don’t just bend over at the waist (腰).
