1. sometimes courteous overlaps in meaning with considerate and thoughtful, however, courteous is emphasizing more on being 'well mannered'. eg (holding a door open for a stranger, saying thank you/sorry/please/bless you, ) The difference is, it is possible to be well mannered and courteous but inconsiderate and thoughtless. 2. 'keep up' and 'keep on' both carries the meaning of continuing to do something but are used in different contexts. eg you have to keep on making money if you want to keep up with your girlfriend's spending needs. 3.equivalent and tantamount are synonyms 4. they are synonyms 5. taste and flavour as a noun are synonyms. The verb form of them have different meanings. eg Can you taste the coconut in the pudding? eg1 can you flavour the pudding with some coconut essence? 6. eg my brother and i went fishing. (if you remove 'my brother' from the sentence, it will still make sense. eg1 my brother and me went fishing. (if you remove 'my brother' from the sentence it will become 'me went fishing' which is wrong. i hope i helped :)

I would say they are used pretty much interchangeably, except that you wouldn't start a sentence with 'because of' because it doesn't sound too good. However, starting a sentence with 'due to' is perfectly fine. eg because of his meddling, i was unable to get laid (sounds fine spoken but doesn't look as good written) -> i was unable to get laid because of his meddling (works either way) eg1. due to his interference, i missed my chance/i missed my chance due to his interference. (works either way in any form)

Can my materials be evaluated first? When I receive my admission I will send you the Proof of Accreditation for my university. I think it is easier if you just split up the sentence.

2. is correct 3. and 4. is both wrong. >the books was given to me by the teacher. 5. and 6. are both grammatically correct. p.s. for 5. I personally prefer to structure it like this> In the past those people were discriminated against by others.

hi sexy ;P

'I had to put a name forward' = I had to nominate/select/choose someone(for something) It is easiest to understand with the following scenario: You sit at a desk and in front of you are 3 name cards laid in a straight line across the desk. Someone asks you to choose a person to be fired. You then proceed to push one of the name cards forward. What you have just done is 'put a name forward'. You have 'chosen/nominated/selected' a person.

Personally I would just say the first sentence is grammatically wrong. The second sentence is correct.
