13.in secret秘密地 & in the secret知道内情
用法：in secret相当于secretly（秘密地），在句中作状语修饰动词，表示动作的私密性。而in the secret一般用在be动词后面，在句中作表语，表示知道某个秘密。
例句1：The greedy woman hid the parcel insecret.
那个贪心的女人偷偷地把包裹藏起来了。
结构分析：The greedy woman是主语（定冠词the和形容词greedy都是前置定语，修饰woman）， hid是谓语动词（hide的过去式），the parcel是宾语， in secret是状语。
例句2：Needless to say, the general manager mustbe in the secret.
不用说，总经理一定知道内情。
结构分析：Needless to say是状语（形容词Needless+不定式to say，构成形容词词组）, the general manager是主语（the general是两个前置定语，修饰manager）， must be是系动词词组， in the secret是表语。
14.in the air在空中，悬而未决 & on the air在广播，在播送中
用法：in the air字面意思表示“在空气中”，引申义为“在空中，不设防，悬而未决，在流传”，相当于in the sky；而on the air则表示“在广播中”。
例句1：The famous dancer can kick his legs high in the air.
那位着名的舞蹈家可以在空中做高踢腿动作。
例句2：The film in which she played the lead role will be on the air tomorrow.
她主演的电影明天播出。
作业动词短语：join in参加 & take part in参加用法：join in和take part in都可以表示“参加”。join in多指参加球赛、游戏等小规模的活动，常用在口语中，而take part in多指参加大规模的活动。
例句1：The new classmate was too shy to join in the game.
例句2：Mark felt that it was time for him to takepart in his community, so he went to the neighborhood meeting after work. (6月六级)
