謝妹妹!

檢討一下:

 

- 用混了 biennial (兩年一次) and biannual (一年兩次).

 - make g profits - typo, should be "make profits"

- several tens of - 好像有這種用法

Corrected version: 

 

 

As the biennial Frankfort Auto Show opens its door to the public on Tuesday, its focus of attention will be on the strong ability of German auto industry to make profits and announcement of tens of new brand cars.
