第30课:① The ball struck him so hard that he nearly fell into the water.
第35课:② The one with the money got such a fright that he dropped the bag.
第44课:③ Mrs. Sterling got so angry that she ran after them. / ④ The men got such a fright that they dropped the bag and ran away.
显然这三课书是讲so/such … that …句型,第44课做总结和复习。亚历山大在写书时的选词用词也是字斟句酌,绝不是偶发奇想:两次get a fright,两次drop the bag,一次so后接形容词、一次接副词,fall与drop的对比,这四点并非巧合。因此我们又能得到第二条甚至更多的“暗线”。这些都是帮助学生在潜移默化地复习、渗透和提高。
