) Ask: Is there a way to tell that the teacher is happy with your work?
Answer:
a) No, not that I know of
b) No, she isn't pleased with it
c) No, I haven't told her
The answer is a. but not b. Why? The question isn't asking how the teacher feels about your work. It is asking you if there is any way you can tell how the teacher feels - is there a method you can use to work out how the teacher feels.
( I'm not so sure about the question, I cannot make out the word after tell, if you can , please download the file here, question 28 http://www.lsa.umich.edu/eli/eli1/ecpe/audio/0304/Track%2004.mp3 ) If haven't listened but the word 'if' would seem more natural.
2) If a person cuts class and leaves home to become a gang member or a hobo or a drug addict. How do you say that verb? Which verb
3) Can I use the term : The US government in a formal writing when no abrreviation allowed. How can I replace the word US? United States - but the whole thing is really United States of America.
