语言点（点击阅读英文解释）
• Mr. Wilson, I’d like you … （威尔逊先生，我想要让你见见……）。请注意“Mr. Wilson,”用的是声调，意在招呼对方。请仔细听“I’d like”中的“d” 的发音。“I’d like”的意思是“I would like”（我想要），它与“I like”（我喜欢）的意思差别很大。（“I’d like”、“I would like” 与“I want”是同一个意思。）
• Dr. Smith is an economist（史密斯博士是位经济学家）。请注意economist（经济学家）这个词是新出现的内容，发音时需要用重音来强调。“economist”这个词有四个音节，重音在第二个音节 (e-CON-o-mist)。
• He just finished writing … “（他刚写完……）中的“just”是指刚刚过去的某个时刻。“just”经常用于动词的“一般过去时态”，但也可以用在“现在完成时态”中，如He’s （= He has）just finished writing …(他刚写完……）。
• Development program（开发项目），这两个词合在一起组成复合词组，主要重音应放在“development”一词上。
• By any chance? 意为“或许有可能”。请注意这里示用升调，这种说法被用在一般疑问句（以是/不是、对/不对作为回答的问句）中，意在确定某事是不是实情。

Language notes
• Mr. Wilson, I’d like you … Notice the rising intonation on “Mr. Wilson,” which is used to address someone. Listen for the “d” in “I’d like.” This means “I would like,” which is very different from “I like.” (“I’d like” means the same as “I would like” or “I want.”)
• Dr. Smith is an economist. Notice the stress on “economist.” This content word has new information, so it is emphasized. There are four syllables in “economist,” with the stress on the second syllable (e-CON-o-mist).
• He just finished writing … “Just” means the very recent past. “Just” is usually used with a simple past verb because the action is complete. However, it can also be used with the present perfect (He’s just finished writing …).
• Development program. Since these two words make a compound noun, the main stress falls on “development.”
• By any chance? means the same as “possibly.” Notice the rising intonation, which is used in yes/no questions to confirm that something is true.
