It means it could have been prevented (avoided).

They are the same. Have a bath (chiefly British English) Take a bath (American English) You can also say: I usually bath (UK) / bathe (US) right before I go to bed.

They are often used interchangeably but there are minor differences: Situated: (formal) = where something is / where you can find something (like building or places in nature) Located: A) To put something in a particular place: The school located its gate near the street. B) If something or someone is located in a certain place they are at or in that place: The convenience store is conveniently located. The bathroom is located on the 3rd floor. So, situated is more formal. Located is more casual. Even though there are some minor differences it's usually okay to use them interchangeably. Lastly, some people might also argue that situated means that something is put somewhere deliberately (like an office on the 3rd floor) whereas located means that something has always been there or been there for a very long time (like a mountain). Good question, I think many people are going to have many different answers to this question.

1) Last out (chiefly British English) means to 'survive' or 'cope' during difficult times. Ex: The company almost went bankrupt last year, we'll have to wait and see if the company will last out this year. 2) When you use 'tide over' it's often good to include: SOMETHING THAT HELPED YOU / it to survive or cope in a difficult situation. Ex: My dad lent me some money to tide me over for a while. Please also note that 'tide over' is often used to refer to difficulties that last for short periods of time. 'last out' = You don't have to mention what saved you or helped your survive or cope 'tide over' = It's often better to mention what helped you cope / survive during (often short term) difficult times. Hope this helps Nanako

Hello. I'm Yuu. I live in Japan and I'm Japanese. I love to traveling. Recently I went to Los Angeles. It was my first time to visit to America!! It was a very great experience. There were many nice people, many beautiful places, many delicious food... and Disney land xD I was so touched when I was there.

I knew in America every things are bigger but it was really! bigger ! :o Everything in America was much bigger than I imagined.
Especially food. I do like eating but I couldn't eat all some times TT Especially the food, I do like eating but I couldn't always finish everything. 
I really wanted to eat all because they were delicious TT but too big to me ... haha I really wanted to finish all my meals because they were so delicious but the portions were just too big.

America was huge ... I want to see many places in America more ! America is huge, there are so many other places in America that I would love to see.
And try to speak English more too. I couldn't say English that much in this time ... ahh I should have used English more:p And I should try to speak English more frequently. I couldn't say much in English this time. I should have tried harder to speak English.

Thanks for taking your time to read this.
Thank you :)

This is VERY formal and polite and NOT commonly used. If you have a huge favor to ask someone in a very formal environment then this phrase could be used. I personally have never used this phrase in real life. I would rather say: Would you please help me?

What exactly do you mean?
