11、分析】根據(jù)全文內(nèi)容可知，作者提到了競走這項運動的好處，同時也指出它的一些危害，態(tài)度是客觀的，故B項正確。二次精讀【詞匯積累】Para. 1:fitness九健康Para.3demanding/.（工作）耍求高的，費力的;（人）苛求的，難滿足的 calculation n.計算;估計 approximately adv.大約 Para.5considerable adj.相當大的;相當多的cautious adj.謹慎的，小心的【難句分析 1 According to most calculations, race walkers moving at a pace of six miles pe

12、r hour wouldburn about 800 calories（卡路里）per hour, which is approximately twice as many as they would burnwalking, although fewer than running, which would probably burn about 1,000 or more calories perhour.（Para.3）分析:本句是一個主從復合句，含有兩個which引導的非限制性定語從句,第一個which引導的定語從句修飾800 calories,第二個which對running進行補充說

24、ere考查定語從句。先行詞是spot,后跟定語從句，關系詞在從句中作地點狀語,故用關系副詞 where erest 考查名詞。句中含有“be+of+名詞”結構,be of particular interest=be particularly interesting, 故填名詞interest o【知識拓展】英語中的“be+of+名詞”結構相當于“be+形容詞”，描述主語的特征或性質(zhì)。常用于這個 結構的名詞有 benefit, importance, interest, help, use, significance, value 等。.than考查連詞。本句中含有more,空格后為

26、詞。此處表示“它的計劃”，故用形容詞性物主代詞its。第四局部寫作第一節(jié)短文改錯Today I tried cooking a simply dish myself. I like eating frying tomatoes with eggs, and Ifriedfriedsimplethought it mustbe easy to cook.

Then I onuntil/tillput the tomatoes and the beaten eggs into A pan together. nNot that way, my mom tried to stop theus but failed. S

28、he was right. It didnt turn out as I had wished, me第一處:simply改為simpleo形容詞和副詞混用。此處修飾名詞dish,故用形容詞simpleo【易錯點撥】英語中的形容詞通常用在名詞之前、系動詞之后和賓語之后，分別作定語、表語和賓語補足語，而用副詞作狀語，修飾形容詞、副詞或整個句子。第二處:frying改為fried。非謂語動詞誤用。過去分詞作定語，表示動作的完成或被動,此處表示被炒過的西紅柿雞蛋，故用過去分詞作定語?，F(xiàn)在分詞作定語表示進行或主動。第三處:刪除to。不定式符號多用。情態(tài)動詞后接動詞原形。第四處:preparing改為p

29、repare。非謂語動詞誤用。不定式符號后跟動詞原形。第五處:but改為and。連詞誤用。此處表示動作的先后，是順承關系，不是轉(zhuǎn)折關系。故將but改為ando第六處:chopstick改為chopsticks。名詞單復數(shù)誤用。chopstick意為“筷子”，常以復數(shù)形式出現(xiàn)。第七處:off改為on。固定搭配誤用。turn off表示“關掉，此處意思為“翻開廚灶，故用turn on。第八處:unless改為until或till。連詞誤用。此處表示“我耐心地等到油熱”。此處引導時間狀語從句,表示直到為止”。第九處:pan前加the。冠詞漏用。此處特指上文提到的平底鍋。第十處:us改為me。人稱代詞

30、誤用。根據(jù)上文提到的T”my mom”可知，此處表示“我媽媽嘗試阻止我,但失敗了”。第二節(jié)書面表達【寫作思路】根據(jù)試題要求，考生需要寫一篇記敘文，記述身邊一位值得尊敬和愛戴的人。首先考生 需要介紹自己最尊敬和愛戴的人是誰，簡單地介紹一下他（她）。然后,陳述為什么他（她）值得尊敬和愛 戴。最后，可以對前文進行一個總結，使文章結構嚴謹。本文的寫作重點在尊敬和愛戴的原因，考生 可圍繞這個要點適當拓展,從性格特點、處事風格等方面展開寫作?！痉段馁p讀】The most beloved and respected person around me is my teacher, Ms Li.

51、th running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But

52、the sports rules require that a race walker9s knees stay straight through most of the leg swing and one foot remain in contact（接觸）with the ground at all times. It9s this strange form that makes race walking such an attractiveactivity, however, says Jaclyn Norberg, an assistant professor of exercise

53、science at Salem State University in Salem, Mass.Like running, race walking is physically demanding, she says. According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories（卡路里）per hour, which is approximately twice as many as they would burn walki

54、ng, although fewer than running, which would probably burn about 1,000 or more calories per hour.However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while rac

55、e walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.As a result, she says, some of the injuries associated with running, such as runners knee, are uncommon among race walkers. But the sporfs strange form does place considerable stress on the ankles an

56、d hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.Why are race walkers conditioned athle
