3.Some parents worry that their children will spend too much time and money on phone calls.

     此句的worry后面接宾语从句。Worry后面还可以接about 构成词组,表示“对…担心”,强调动作;另外,词组be worried about 也表示“对…担心”,强调状态。

      再如:      Where have you been? We’ve been worried about you.

     你去哪儿了?我们一直都在为你担心。

   Parents always worry about their children.

     父母总是为自己的孩子担心。

[考点透视 考例精析]

   [考点]  考查谓语动词被动语态的用法。

   [考例1]  --Have you moved into the new house?

     --Not, yet, the rooms _______________.

      A.are being painted                    B.are painting 

      C.are painted                           D.are being painting

   [解析]  A 本句的意思是“因为新房子正在粉刷,所以我还没有搬进去”。用现在进行时的被动语态。

   [拓展]  除了现在进行时的被动语态,过去进行时的被动语态也是值得注意的一点。

      例如:

      The lost children were last seen playing by the side of the river.

      最后有人看见那些失踪的孩子在河边玩。

   [考点]  介词短语的语义辨析。

   [考例2]  I don’t think I’ll need any money but I’ll bring some ___________.

      A.at last          B.in case         C.once again      D.in time

   [解析]  B 本句前面的分句已经说明“主语认为自己不需要钱”,所以but后的分句说明“带上点钱以防万一”。

   [拓展]  in case与in case of的用法要注意。再如:

   Take an umbrella with you in case it rains.

   随手带把伞以防天下雨。

   In case of danger he was always standing in front of me.

   在危机时刻他总是站在我前面。

   In case of fire, you should always stay calm.

   在发生火灾的时候,你应该总是保持镇定。

   [考点]  考查turn构成的词组的用法。

   [考例3]  The children are always _________ practicing playing football when they have PE lessons.

      A.taking turns     B.by turns        C.in turns         D.at turns

   [解析]  A 本句的空白处缺少谓语。因而用take turns doing something结构,意思是“轮流做某事”;by turns和in turn都可以表示“轮流做某事”,但都是介词短语,只能作状语。

   [考点]  考察动词的时态。

   [考例4]  Mr. Smith searched the Internet for nearly two hours before he _________.

      A.was decided well                     B.had made a good decision

      C.made a good decision                  D.has made up his mind

   [解析]  C 本句的主句用了一般过去时态,因此也决定了从句的时态。排除了B、D项;make up one’s mind意思是“做出决定”,但是时态不对。
