Homonyms - 2 words that sound alike but have different meanings. For example, "read", as in "I read the article, yesterday", and "red", as in the color red. "Hair", as in what grows out of your head, and "heir", as in the someone who will inherit (The eldest prince is heir to the throne). It may be helpful to remember that "homo", from the original Greek, means "same". So homonyms have the same sounds. Synonyms - Words that mean the same thing or almost the same thing. Often, they can be used interchangeably. For example, "coat" and "jacket", "soda" and "pop", and "auto" and "car". Antonyms - Words that are the exact opposite in meaning. "Hot" versus "cold", "fast" vs "slow", and "clean" vs "dirty". ("vs" is the abbreviation for versus.). As far as the other words, I can't help you.

1) Last week I spent a most enjoyable few days in Stratford-upon-Avon with three my friends (maybe "friends of mine" souds better?) Last week, I enjoyed a few days in Stratford-upon-Avon with my three friends. (Direct sentences are often easier to understand.) 2) We decided to go several weeks ago and I have booked rooms for the four of us at a hotel in the town. We decided to go, several weeks ago, so I booked rooms for us at a local hotel. (Inserting commas around time makes it easier to read. The words following "so" give the reason why you booked the rooms. You could also substitute "therefore". The sentence would then read "We decided to go, several weeks ago, therefore I booked rooms for us at at a local hotel." 3)The hotel was really impressive on the outside but the bedrooms were rather small. We arrived quite late on the first evening as we had been working during the whole day and all we wanted to do then was to have a good meal and go to our beds The hotel was really impressive outside but the bedrooms were rather small. We arrived quite late since we worked all day so all we wanted to do was to have a good meal and go to bed. (Again, try to be short and sweet. Your meaning will often be clearer.) 4)The following morning we got up quite late and had a large breakfast in the hotel. Great as is! 5)We spent the rest of the day driving around the countryside, stopping every now and again to take short walks. (or i should say "taking short walks"?) We spent the rest of the day driving around the countryside, stopping every now and then to take short walks. (In American English, the phrase is "now and then").

"I can do nothing except watch TV." Sometimes substituting another verb can clarify which form you should use. For example, "I can do nothing except play." "I can do nothing except read." "I can do nothing except work." "I can do nothing except clean." Using "-ing" in any of these sentences sounds awkward.

You travel from somewhere else TO Spain (i.e. from England to Spain). But, if while in Spain, you decide to go visiting, say, Castile, you can say, "While in Spain, I took a trip to Castile."

Rachel54 is correct. The "while" in this sentence implies that both statements are simultaneously true. It's true that the museum is more about the past and it's also true that the travel is always about the present.

They mean almost the same thing and can be used interchangeably. You can say "What kind/type/sort of music do you like?" (Rock? Pop? R&B?) "What kind/type/sort of person is she?" (Nice? Smart? Fun? Hard working?)

If your goal is to make your sentences sound more natural, use simple words and short, direct sentences. "To avoid meeting his former friends, he stayed inside." "The top countries for police corruption are..." "This type of yoga energies people and improves the ability to focus." "Real men respect women as humans, not sexual toys." "Women and men can be friends." Irregardless of gender, sexual harassment should be strictly enforced."
