be prepared to search for the lion at any time when needed． At about 1：30 in the afternoon，we were told to go out immediately，for it was reported that the lion had appeared in the bushes in a lady’s garden．We drove our truck as fast as we could．When we got there，we found the garden had already been surrounded by the police．And the lion could be seen in the bushes，eating something．We walked quietly towards the bushes．As we got near，I pointed my pipe at the lion and fired．The lion made a sudden an-gry noise and struggled to its feet．After a moment，it fell over and lay still．In this way we caught the lion and took it back to the zoo． 4．教师要求学生从两篇课文中找出以下相关内容： 1）Expressions used to describe the young lion．2）Words and sentences used to describe how frightened Mrs．Cousins was．3）Sentences

make the tank look much pretti-er．一则它们（指水下植物）可以使水保持清洁，再者它们可以使水箱看 起来更加漂亮。 for one thing意为：首先，常用来举出理由，用在 For one thing…；for another或 For one thing…also…的结构中，意为：首先……；其次……。例如： For one thing there isn’t time；for another we haven’t enough money．首先， 没有时间；再者，我们也没有足够的钱。 I can’t go—for one thing I have no money，and for another，I have too much work．我不能去。首先是我没有钱，其次我的工作太多。 2．She was just about to open the window and shout at the dog to frighten it，when she stopped and stood quite still．她正准备打开窗户，大声吓唬一下那 条狗，这时她突然停住了，站着一动也不动。 be about to do sth．意为：正要做某事。例如： Don’t go away．We’re about to start．不要走开，我们马上就开始了。 He met her in the doorway just as she was about to leave．正当她要离开房间 时，他在门口碰见了她。 be about to do sth．这一结构常和 when连用，表示：正在……时，发生了 ……事。例如： The headmaster was about to leave the office when suddenly a boy rushed in． 校长正要离开办公室，这时一个男孩冲了进来。 I was about to go to bed when there was a knock at the door．我正要去睡觉， 忽然听到敲门声。 3．Mrs．Cousins held her breath，and her body went cold．卡曾斯太太屏住 气，全身发冷。 hold one’s breath意为：屏住气；不出声。例如： He held his breath as the runners rushed towards the finishing line．当赛跑运动 员向终点冲刺时，他紧张地屏住了气息。 She held her breath and dived．她屏住气开始下潜。 在 her whole body went cold中，went为连系动词，意为：变得。例如： The milk has gone bad．牛奶变质了。 His black hair was going grey．他的头发变得花白了。 4．After a moment，it fell over and lay still．不一会儿，它（指狮子）就摔 倒在地，一动不动了。 句中 lay still可以看作是系表结构，lie（过去式为 lay）可以理解为 remain。lay still相当于 remained unmoving。除 lie以外，stand，sit等动词也可接 形容词作表语。例如： He stood still without saying anything．他一句话不说，一动不动地站在那里。 She sat motionless，waiting for the decision．她坐着不动，等着做出决定。
