Learn English – which preposition should go with attractive

In Standard English we use at with study when stating the University name:

I studied psychology at Cambridge University

I want to study at Imperial College University, London.

Use of in is not Standard English, even to the point where the ngram of studied at MIT versus studied in MIT does not even show in because it is so non-standard.

My guess is that whoever wrote that quote was not a native speaker of English.

In the following extract, the first & last items are from American sources, and the middle one is from a British source.

The first two items support the fact that to give somebody a hand is used to mean "to help someone". The third item confirms that (especially in US usage), that may also be expressed as "to lend somebody a hand"; although less common, that usage is certainly not unknown — and would certainly be understood — in the UK.

Conversely, if one were asking for help, one might say "Would you please give me a hand with this?". The expression would certainly be "give me a hand", but the "me" might be partially 'swallowed' and not heard clearly.

If offering help, I might say "Do you want a hand with that?". It's easy to see that a non-native speaker may get confused between "give me a hand" and "Do you want a hand?".

(As an aside, the usage of give a big hand to someone (note the word "big" in the middle) to mean "give a round of applause" is also common in the UK.)

Finally, although the expression "I will help you" may be slightly non-idiomatic, I cannot think that by itself it should be so strange as to make people laugh; but it's possible that it might sound funny in the context of something said previously.
