A．two thirds，isB．second three，are
C．two thirds，areD．two third，are

分析 我認(rèn)為考試前面的三分之二的聽(tīng)力材料很簡(jiǎn)單．

解答 答案：C
結(jié)合句意：我認(rèn)為考試前面三分之二的聽(tīng)力材料很簡(jiǎn)單．本題第一空考查的是分?jǐn)?shù)，在英語(yǔ)中，基數(shù)詞表示分子，序數(shù)詞表示分母，當(dāng)分子大于一時(shí)，分母要加s，所以三分之二應(yīng)該是two-thirds；第二空因?yàn)榍懊娴膍aterials材料是復(fù)數(shù)，三分之二的聽(tīng)力材料也是復(fù)數(shù)，應(yīng)該用are，故選C．

點(diǎn)評(píng) 本題考查的是分?jǐn)?shù)和be動(dòng)詞的用法，理解句意并掌握分?jǐn)?shù)的構(gòu)成的解答本題的關(guān)鍵．

Hi Grace，
    How's it going？Sorry I haven't emailed fora while，but I had so much to do!I had told you about my decision to take up a sport．I knew I wasn't fit and I wanted to get some exercise．But that wasn't the only reason that I decided to do a sport．Students who play sports do better at school．（86）FExercise also helps learning and memory （記憶）． （87）BFirst，I tried soccer．I had played a bit of soccer before and I thought it wouldn't be too bad．I knew I couldn't nm for very long without feeling tired．On the first day，I was able to nm for the first ten minutes，but then I was so tired that I couldn'teven kick the ball!
    Then，I tried volleyball．（88）D I was able to nm for the first twenty minutes and Iwasn't the slowest runner in the team!After a few weeks．I could run faster and longer．Iwas doing better and feeling better．（89）E Maybe I'm not a teamsport person after all!
    Finally，I tried kung fu．It's a great sport that exercises the body and the mind．You learn to follow instructions carefully and do what you are asked to do．This is the fight sport for me!（90）G I feel so confident that leven showed some moves to the class last week!Can you believe it？
     I hope you're OK!Write and let me know what you've been doing!
      Bye for now!
                                                        Kristie．
