Then how did you get here

1. Life is full of the unexpected.
unexpected adj. 出乎意料的；始料不及的
e.g. It will not be unexpected if Tom comes late again, because he is always like this.
如果汤姆又迟到了，一点也不意 外，因为他一向如此。
the unexpected 为名词化的形容词，意为
“出乎意料的事”。 英语中，有些形容词与定冠词the连用，表示一类人或事物，在句子中起名词的作用。
例：the homeless (无家可归者)
the disabled(残疾人)
the unwanted( 无人认领物品)
当名词化的形容词用作主语时，谓语动词的单复数形式取决于它们所表示的概念的单复数情况。 多数情况下，表示一类人或物品时，谓语动词用复数；少数情况下，当指抽象概念或不可数的物品及事件时，谓语动词用单数。
例：The sick are always taken good care of in that hospital. 在那家医院里病人们总是受到很好的照顾。(the sick=the sick people)
(2) 这种结构中的形容词虽已名词化，但其语言
行为仍具有极强的形容词特征，受到副词修饰
或具有比较的特征。
例：The severely disabled need full-time care.重
度残疾人需要全天候拌护。
He is spoiled, and always asks for the most
expensive.
他被惯坏了，总是嚷着要最贵的东西。
(3) 名词化的形容词前面一般用定冠词the. 但
若由and链接(两形容词往往为反义词），
成对的使用时，又通常被省略。
例： He is popular with both young and old.
老老少少都喜欢他。
It is said that the man was widely
respected by both rich and poor.
据说那个人颇收人尊敬，无论是穷人还
是富人。
2. By the time I got up, my brother ______
already ______ in the shower. 我起床时，我弟弟已经进入浴室了。
“by the time”表示“当/到……时”，引导时间状语从句。如果从句中用了一般过去时，主语中常用过去完成时；如果主句中用了将来时，从句中常用一般现在时表将来。
例：By the time I got up, he had already left.
当我起床时，他已经离开了。
He will be a teacher by the time he is
twenty.
到他二十岁时，他会成为一名教师。

，
通常与现在完成时
连用。

3.When I got to school, I realized I ______
______ my backpack at home. 当我到学校时我意识到我把书包忘在家里了。
表示“把某物忘在某处”要用词组leave sth. +地点。
forget意为“遗忘某物”，指忘记一件具体的东西，但不能有具体的地点。
例：I my______ book on the desk.
我把书忘在了桌 子上。
I______ my umbrella yesterday .
我昨天忘了带伞。
left
forgot
【辨析】leave 与forget的用法: (1) leave “ 遗留，落下，忘记带”，侧重指把某物或某人留在某个地方，后常跟地点状语； （2）forget “ 忘记”，侧重指忘记某件事情，后常跟to do (忘了要去做)或doing (忘了做过)。 【拓展】 leave → left → left v 离开 (1)leave sth +地点 把某物遗忘在某地
(2)leave for +地点 离开去某地 (3) leave a message 留言
ask for leave 请假
