英语选择 I_____ my pen at home ,so I have no pen to write with. A threw B dropped C forgot D left 答案：D.把某物忘在某地“leave sth.+地点” Have you finished writing the letter _____?Not ______ A just;already B already;just C ever;just D yet;yet 答案：D。现在完成时态，否定句和一般疑问句中表示“还；仍然”之意，要用yet。
A和C在意思上就不对，先排除，然后看B和D。 B和D容易混淆。 forget"的英文解释是：neglect or fail (to do sth) ，它的词性是及物动词，在后面加上动词不定式to do时，表示"忘记去做某事"。 "Leave"的英文解释是：neglect or forget to bring，take or do sth。它的词性也是及物动词，它的后面要加名词或代词，表示"忘记携带，留下，遗落"。 重点：forget是忘记一件事，不与具体地点连用；而leave可与具体地点连用，侧重把某物遗忘在某地。
