hi...Loveruby!
I support your idea stated that the TOEFL is terribly difficult.
Well, I really admire the students who can get more than 550 scores for the exam, they are very clever anyways!
However, in order to measure each student's knowledge, all the exam must consist of both difficult part and easy part. One exam can't be very difficult from the begining to the end.
Like Paul said:"Remember you dont have to know everything, you just have to know enough to pass, because it is an exam."
In addition, I am also a TOEFL preparation student at the moment, and I find it very difficult to understand about the slang and idiom which appear in the Speaking section the same way as you do. But sometimes I enable to guess some of them, because they are everyday slang or idiom!
In my view, reading or learning about the slang or idiom from a collection books can be useful, but not very effective for every students.
From my own experience, It is a better idea that student should try to listen to the English programmes more , or watching American movies, listen to English radio.... etc.
why?
Well, for example, I learned the new idiom like "be over the moon,hit the roof,bury your head in the sand"something like that from the book in the morning,then I watch the American Movie at night, when I hear the word being spoken again, I not only remember it in my head, but also I can understand its meaning clearer and know in which condition or circumstance that we use it!
Secondly for the vocabularies, one of the members whose name called"asheap" said:
" 1. The Heinemann TOEFL Preparation Course / Heinemann, M.Kathleen Mahnke & Carolyn B. Duffy
It contains all part of TOEFL test including vocabulary. I like its vocabulrary part which explains how to remember words."
I have not read through the book yet, but I will try soon!
Oh......I also would like to say thank to Asheap for your comment, and especially Paul: Both of you have been providing both practical and good ideas to me!
Finallly, I hope that I will hear from you( loveruby) again that TOEFL isn't terribly difficult, but it is just a piece of cake next time!
Bye....
