单选题 Most visitors to the United States will need a visa(签证) as well as a passport and a health record. There are various kinds of visas depending on the estimated length of stay, even more important, on the purpose of your visit. For example, among the types of visas available are: B1-- Normal short visits for business, B2-- Normal short visits for pleasure, Fl-- Student, and F2-- Family of student.
A small white form, 1-94, will be attached to your passport showing your classification (类别), arrival date, purpose of visit, and departure date. If you want to stay longer than the date on this form, you must apply to the United States Immigration Service (移民局) for an "Extension of Stay" at least one month before the date indicated. Be sure not to stay beyond the date on which you should leave without an approved extension.

【答案解析】[解析] 词义推测题。
[解析] 推测departure date的意义。从上下文分析，前面出现了一个arrival date(到达日期)，那么与之相对肯定就是“离开日期”，所以只有选项D符合题意。词义推测的技巧常用的有：1)有些句子里对词义有解释，通常会有破折号或冒号这样的标志性标点符号；或者以定语从句等从句形式出现；2)有些句子里可以找到生词的并列对等成分，或生词的反义词；3)在句子中可以找到例子来说明生词，通过例子可以推测词义：4)有些构词法知识可以帮助我们。
