italicizes

1. As you read, you'll notice that Salinger frequently italicizes words. This is part of his attempt to accurately duplicate speech patterns- an italicized word is one that is emphasized or stressed when spoken.
    在你阅读时，你会注意到塞林格频繁地给词语画下划线，这部分是因为他想要加倍地强调这种语言风格——画下划线的词在被说出时要强调或加重音。

2. And when he prints it, in England, France, Germany, and Italy, he italicizes it, puts some whooping exclamation-points after it, and sometimes explains it in a parenthesis.
    而要是印刷出来，在英国、法国、德国和意大利，他会把笑点用斜体标识出来，其后再加上一些表示喊叫的感叹号，而且，有时还加以解释放在括号里。
