It might help to realise that "fend off" has, as its core meaning, "push away" or perhaps "use force to repel". For example, when you are in a small boat approaching a dock, you might want to avoid hitting it, so you would push away with your hands. You might yell "fend off" to tell people in the boat to do that. "Fend off" is also used figuratively. For example, to "fend off awkward questions" would be (in some way) to deter or push away questions you did not want answering. In a situation of attack, "fending off" focuses on the pushing away of the attackers, by some means, whereas fighting back could include many actions some of them more active - as George says, it is a more active thing to do.

My friendship

I find it hard to make friends,so I have a small circle of friends.
I always get nervous when I meet new people, but when I do become friends with someone,I really open up.
So my friends tells me you are different from the person we met at for the first time, because they think I am quiet person.They are surprised that I tell my friends about my opinion.
I don't often go out with friends, but sometimes I gather at my friends' and go out for girl's night.
I really enjoy spending time with my friends.

Diary in English ♡ On the 26th of March My Weekend

Time flies, especially if it is weekend. My days off are Sunday and Monday.
On Saturday, I realized that I got a text from my ex housemate after I finished working. She texted me that she was in London that day and she was going to leave at 8 pm. I replied to her immediately and we met at a cafe near the Victoria coach station. We had a nice time and talked over coffee to catch up. I was happy to chat with her because I've felt a bit lonely since I moved to London. I haven't had close friends here, so I really missed my friends in Bristol.
As she is going to finish her course in a few weeks, we are thinking about a small trip. If I can get holidays, we will travel together.

On Sunday, I just relaxed at home. I watched You Tube and Netflix a lot. I was a couch potato!

On Monday, I did a lot! First, I sent a letter to claim a refund as I had paid a lot of money to receive a parcel from my mother in Japan. I asked her to send some clothes and food, and she did that for me, but the UK government asked me to pay the duty and VAT even though they were items for personal use! I am sure I hadn't had to pay for it. I paid in order to receive the parcel, but I hope the claim will be accepted. Second, I went to the library and got my library card. I registered my account online in advance, so it was easy to get the card. Third, I went to a clinic to register it as my GP. I filled in a form and show my ID and two proofs of address. I didn't need to see a doctor to register, so it was easier than I expected.

And then I went shopping to some supermarkets and came back home. I had some coffee and scones, studied English and chatted with my landlady. It was nice weekend.

"Key to attracting" would be much better in British English. British English has a tendency to use participles (like "attracting") where other languages use infinitives. Many users of English use infinities (like "to attract") which always sound wrong to my ear.

Initiation
As usual some sweat dropped over his wide forehead, when he entered the wide door in the wide lecture hall. He didn't look at anyone, until he stopped behind the small desk. He put some papers and books on the desk quickly. The paper fell on the floor. Some people laughed at him secretly. He looked at the paper which was full on the floor for long seconds. Then he completely ignored the paper. He raised his eyes towards the students for the first time since he had entered the hall. He said after a long period of silence "we can take this lecture in two ways: Scientific style، Scientific terms, some rules and we will enter Deep psychology; or simple explanation, which doesn't relate to science, a simple style in explanation, like you are talking with your friend, and we will care about emotions and feelings. What do you think?!" They looked at each other In confusion, They always got confused when presented with choices. They had never had a teacher who made them chose.

Hoang Kha's advice is excellent. The best advice is to do it, a lot. Here is good because (hopefully) nice people will correct you. I will certainly try to if you ask me. But see if you can find other places where people will comment on your writing. Another thing to do is to make sure you read as widely as you can. If you can find English literature that you find interesting that will help your writing style. Some English is written in an odd style: for example newspapers and of course many blogs, comments and web pages. It is better to try to read well-written English if you can. If you can bear to do so - and this can be too much for people - study some formal English grammar so that you understand the structure of sentences and the roles that each word plays in the sentence. I find the more I understand the better I write English. I am trying to apply the same approach to Egyptian Arabic but it is quite hard.

As others have said, this is an example of a distinction in British English between a verb (practise) and a noun (practice). There are a few other examples in British English, such as device v devise and licence v license. There is a useful page at https://www.spellzone.com/blog/Commonly_Confused_Words-cc_-ice_Nouns_vs._-ise_Verbs.htm which gives examples of four of them. Americans do not make this distinction. Many British English people get this wrong. You will really impress if you get it right. As a lawyer I deal with software licences a lot and I have to be very careful when I write contracts.
