Leaning Experience of ESP Course of Civil Engineering

I’m looking forward to this subject for a long time.It comes at juniors finally.But I was

disappointed by the teaching materials.It’s totally difference of my imagination.All of the contents of this teaching materials are articals!

Senseless subject!This is my first impression after I got the material.But then I felt confused.The content isn’t connect too much of the material except the words.Most contents are usages of grammar and sentence patterns.I felt headache.

After a period of study,I got some key points of this subject.The meaning of words are different of its common meaning.We must pay attention to it.Some sentence patterns are very important and their usages are different also.

Learing this subjet must be rigorous.Notnoly this but also others too.Succed only based on rigorous learning.This is what I got in this subject.
