这段英文需要修改哪些地方?
Now,it is comes to the analysis of learning
curve in PR company.In fact,the performance of PR company is in the periods
of no return show up on the curve as a fairly straight horizontal line.
Although the training is implementation ,but the performance is still plateau.
What is the cause of this phenomenon?In my opinion,several reasons can be listed
as follow.First and foremost,whether attend the training class or not is
voluntary,all employees who interested can comes to class.The training is not
a target training.Second,the time arranged in a wrong way.Time be arranged
in the evening of Friday,so many people go home early just listened half of
course,some who still in the class are absence of mind.Moreover,the
motivation is not enough for PR company,even though the manager said that
employees attended the training class actively will be record in the personal
document and involves with the salary and promotion in the future.It is
obvious that lack of motivation for employees to attend the training because
most employees needed to training is at basic level.What attracts them is the
immediate interests instead of promotion and so on.

Now,it comes (let us turn) to the analysis of learning
curve in PR company.In fact,the performance of PR company shows no return during this period as indicated by a fairly straight horizontal line.
Although the training is implemented/improving,but the performance shows no improvement/remains the same/is still the same with no improvement.
What is the cause of this phenomenon?In my opinion,there are several reasons.First and foremost,whether attending the training class or not is
voluntary.Only employees who are interested come to the class.The training is not
a targeted training implemented by the company.Second,the class is arranged on every Friday evening,which is a big mistake.Many people want to go home early,so they just attended the first half of the class.Even for those who stay in the class,they tend to be absent-minded.Moreover,although the manager said that
employees who actively attended the training class will be recorded in their personal
documents and linked to salary increase and promotion in the future,there is still not enough motivation for most employees need training at the basic level.What attracts them is the training which can meet their
immediate interests instead of promotion and so on,something too far away for them to reach.
