✔ 最佳答案
First of all, 壓力 is pressure not pleasure. Pleasure means 歡欣/ 榮幸.
Secondly, you should not have used 'many' in this case as 'pressure' is an uncountable noun; therefore, 'much' should be used.
Thridly, 'gonna' is the short form of 'going to', so 'are' should be used instead of 'will'.
(What are you gonna do if you'er under so much pressure?)
How can you cope with a high level of work pressure? is one of the ways in carrying the same meaning. This is more formal.
