Key words and expressions

1. find & lose

find和lose都可作及物动词，后面可直接接宾语。find的意思是“发现；找到”，lose的意思是“失去；丢失”。它们是一对反义词。如：

I find an eraser on my desk. 

我在我的课桌上发现一块橡皮。

People often lose things when they're travelling or when they're in a hurry. 

人们在旅行中或是勿匆忙忙时经常丢东西。

[Practice]

根据括号中所给汉语填空。

1. She can’t _____ (找到) her gloves. She often ____ (丢失) things. 

2. I ______ (丢失) my wallet yesterday; I can’t ______ (找到) it everywhere.

... ... ...

2. look for 

look for是一个动词短语，意思是 “寻找”。由于for是介词，所以后面要接名词或代词作宾语，look for sth.意为“寻找某物”，使用时注意，look for不能分开使用。如：

I can help you look for the wallet. 

我可以帮你找钱包。

They are looking for their phones, cameras, watches, computers and many other things. 

他们正在寻找他们的电话、照相机、手表、电脑和其他许多东西。(由于本句中的时态是现在进行时态，所以要将动词look变为现在分词形式，即looking。)

[辨析] find和look for的用法

find和look for 都有“找”的意思，但含义不同。find 强调“找”的结果，而look for 强调“找”的过程。如：

He is looking for his bike.

他在找他的自行车。

I’m looking for my watch, but can’t find it.

我在找我的手表，但是找不到。

I hope you will soon find your lost ring.

希望你尽快找到丢失的戒指。
