選修8 unit 3 課堂輔導
grammar
1. the first thing i tried to do was to see if there were products that might help me, but there only seemed to be powders designed to kill snakes. 首先我查看是否有產品能幫助我,但看來只有一種毒殺蛇的藥粉。(p.20)
「點撥1」本句中there seemed to be是there be句型的特殊形式,表示“似乎有”。注意其時態的變化,如:seem to do / seem to be doing / seem to have done 等。
「點撥2」 designed過去分詞作后置定語,修飾前面的名詞powders,表被動。
「考例」
“things ______ never come again!” i couldn‘t help talking to myself.
a. lost b. losing c. to lose d. have lost「解析」答案a. 句意為:“失去的事物不會再回來!”我忍不住自言自語。本題考查非謂語動詞。因為things和lose之間是被動關系,須用過去分詞作定語。單個的過去分詞作定語時一般位于名詞之前,但有時為了強調,也可放在名詞之后作后置定語。
2. for the second attempt i froze the bowl and ice-cubes again but placed them over the snakes habitat in the evening as the temperature was staring to cool. 第二次試驗時,我把碗和冰塊再次凍好,但在傍晚氣溫開始下降的時候把它們放在蛇穴的上方。(p.20)
「點撥」 本句中but連接兩個并列的動作froze和placed; as引導時間狀語從句,表示“當……時候”。注意 as在英語中起的作用很多,它可以引導時間狀語從句、讓步狀語從句、原因狀語從句、定語從句等。
「考例」
______, his idea was accepted by all the people at the meeting.
a. strange as might it sound b. as it might sound strange c. as strange it might sound d. strange as it might sound「解析」 答案d.句意為:盡管他的想法聽起來有些奇怪,但與會的所有人都接受了。本題考查倒裝語序。 as引導讓步狀語從句時,作表語的形容詞要前置。
3. pressed by my friends and relations, i decided to send my invention to the patent office to get recognition for my successful idea. 在親戚朋友的督促下,我決定把我的發明送到專利局去,使我的成功創意獲得認證。(p.21)
「點撥」 本句中pressed by是過去分詞短語作原因狀語,表被動; to get 是不定式作目的狀語。
「考例」
______ by a greater demand of vegetables, farmers have built more green houses.
