课堂探究 Class Exploration
语言点学习 Language Points
语言点一：be born
【规则讲解】 be born 意为“出生”，固定用一般过去时 was/were born。
常见搭配：be born in + 年份/月份/地点；be born on + 具体日期；be born with + 天赋（生来具有……）。
例句1：Zhong Yang was born in 1964.
例句2：Lei Feng was born on December 18, 1940.
例句3：The baby was born with a smile.
练习1：选择题
Lei Feng was born ___ December 18, 1940.
A. in
B. on
C. at
D. of
答案：______
练习2：选择题
My father was born ___ Shanghai.
A. in
B. on
C. at
D. to
答案：______
【易错提示】be born 的时态与介词
be born 一律用一般过去时 was/were born，不能用 is/am/are born。介词选择：年份、月份、季节、地点用 in；具体的某一天（带日期/星期）用 on；天赋用 with。判断关键：看时间词是“段”还是“点”。
语言点二：when/while doing sth
【规则讲解】 when/while doing sth. 是时间状语从句的省略结构。
当从句主语与主句主语一致，且从句谓语含有 be 动词时，可同时省略“主语 + be”，只保留 doing（现在分词）。
例句1：Zhong Yang knew it was better to include more people when doing important work.
例句2：While walking along the street, I met an old friend. (= While I was walking ...)
练习1：选择题
______ along the street, I met an old friend.
A. While walked
B. While walking
C. While I walking
D. While to walk
答案：______
练习2：用所给词的适当形式填空
While __________ (play) basketball, he hurt his leg.
答案：__________
【理解要点】when/while doing sth. 的省略条件
省略必须同时满足两个条件：①从句主语与主句主语相同；②从句谓语是 be + doing（或 be + 形容词/介词短语）。省略后保留 doing。若主语不一致则不可省略，否则造成悬垂分词错误。
语言点三：leave behind
【规则讲解】 leave behind 意为“留下；遗留；忘记携带”，
属于“动词 + 副词”型短语。宾语为名词时可放中间或后面；宾语为代词（it/them）时必须放在中间（leave it behind）。
例句1：Zhong Yang left behind more than just a huge collection of seeds.
例句2：Don't leave your umbrella behind. / Don't leave it behind.
练习1：选择题
Please don't ______ your books behind.
A. leave
B. left
C. leaving
D. to leave
答案：______
练习2：用 leave behind 的适当形式填空
He always _______ ______ his homework at home. (用 leave behind 的适当形式)
答案：______________
【易错提示】“动副”短语与代词宾语的位置
“动词 + 副词”型短语（如 leave behind, pick up, put on, turn on）：宾语为名词时位置灵活（leave the books behind / leave behind the books）；宾语为代词时必须放中间（leave them behind ，leave behind them ）。
