译句：Shanghai has gone through many changes and now it has become a world-famous economic center.

　　例6：我为这些话所深深感动，后来我就把它们写在圣诞贺卡上。（impress）

　　分析：在注意到impress使用的基础上，尽管从原句中无法读出如此…以至于…的意思，但要想到句中缺少一定的连接词，这时就可以运用到so…that…结构。

　　译句：I was so impressed by these words that I used them later for a Christmas card.
