    § Lesson 1 A puma at large 逃遁的美洲獅 listen to the tape then answer the question below. 聽錄音, 然后回答以下問題.
    Where must the puma have come from?
    Pumas are large, cat-like animals which are found in America. When reports came into London Zoo that a wild puma had been spotted forty-five miles south of London, they were not taken seriously. However, as the evidence began to accumulate, experts from the Zoo felt obliged to investigate, for the descriptions given by people who claimed to have seen the puma were extraordinarily similar.
    The hunt for the puma began in a small village where a woman picking blackberries saw 'a large cat' only five yards away from her. It immediately ran away when she saw it, and experts confirmed that a puma will not attack a human being unless it is cornered. The search proved difficult, for the puma was often observed at one place in the morning and at another place twenty miles away in the evening. Wherever it went, it left behind it a trail of dead deer and small animals like rabbits. Paw prints were seen in a number of places and puma fur was found clinging to bushes. Several people complained of 'cat-like noises' at night and a businessman on a fishing trip saw the puma up a tree. The experts were now fully convinced that the animal was a puma, but where had it come from? As no pumas had been reported missing from any zoo in the country, this one must have been in the possession of a private collector and somehow managed to escape. The hunt went on for several weeks, but the puma was not caught. It is disturbing to think that a dangerous wild animal is still at large in the quiet countryside.

    一般來講定語從句和同位語從句緊隨在被修飾名詞后面,但為了保持句子平衡,也可以把謂語動詞放到從句之前
    定語從句只是對于被修飾詞的補充說明、修飾。 同位語從句則是講述被修飾名詞的內(nèi)容 定語從句的引導(dǎo)詞:
    指人:主語 who; 賓語 who/whom; 定語 whose
    表達事物:that(也可指人)/ which
    時間狀語:when; 地點狀語:where; 原因狀語: why
    同位語從句:名詞做主語、賓語時,關(guān)系詞用that 而不是which
    時間 when; 地點 where
    eg: An idea came to her that she might do the experiment in another way.
    I have no idea what has happened to him. 定語從句中沒有what 這個關(guān)系詞,但它可以引導(dǎo)同位語從句
    (An idea)„come to sb.某人突然想到了„„
    take sth. seriously==deal with sth. seriously 認(rèn)真(嚴(yán)肅)對待某事
    take sth. lightly: 草率對待某事
    as 隨著
    過去分詞做定語
    聲稱曾經(jīng)作過某事: claim to have done sth
    I still remember the school where I studied English.
    L01-03 end 13‟09”
    L01-04 begin 11‟49” confirm: be sure, be certain search=hunt
    把某物留在后面:leave behind
    Wherever he went, the wound soldier left behind him a trail of blood.傷員所到之處,都留下道道血跡。
