20．Carl hopes to win the tennis game one day．That is    he has been practicing hard．（　�。�
A．whyB．howC．becauseD．where

分析 Carl 希望有一天贏得這場(chǎng)網(wǎng)球比賽．這是他一直都在刻苦訓(xùn)練的原因．

解答 答案：A
分析句子結(jié)構(gòu)可知，由于此處用在了系動(dòng)詞is之后，故本句為表語從句；在表語從句中，連接副詞 why作原因狀語；后面跟的表示結(jié)果"（為什么）…的原因"；how 作方式狀語；because作原因狀語，后面跟的表示原因："那是因?yàn)椤?；where作地點(diǎn)狀語；根據(jù)句意可知；此處表示：他一直都在刻苦訓(xùn)練的原因；故選A

點(diǎn)評(píng) 本題考查了表語從句的用法．在做本題時(shí)，首先通過分析句子結(jié)構(gòu)，判斷該句為表語從句；其次應(yīng)根據(jù)句意并結(jié)合各連接詞的用法，選出正確答案；另外，還應(yīng)記住That is why （后面跟的表示結(jié)果"（為什么）…的原因"）與 That is because（后面跟的表示原因："那是因?yàn)椤?）的用法區(qū)別．

A "Dutch defense" means surrender（投降），although the Dutch never surrendered an inch of their homeland without a heroic fight.

In these phrases the English imply that the Dutch are cheap and not brave enough. 3. When most people think of Holland, they imagine huge fields of tulips（郁金香），tall windmills（風(fēng)車）and children wearing wooden shoes一pleasant and positive things.
