My hobby : Riding a bicycle

I love riding a bicycle. I can remember riding my bike for the first time. It was about a year ago. It suddenly occurred to me that I wanted to ride a bicycle. I might be was inspired when I saw people riding a bike bicycle riders in on a the train. But I was in the a dormitory and didn't have a bike. So, I started to search the Internet to find a good used bicycle. Finally, I found a bicycle that was sold at a big discount of 50 percent off. I decided to buy it because I didn't care if it was used one. I made a direct deal purchase around Seonbawi station and I rode the bike home from there on the bike path. I can't I'll never forget about the memories, memory: the smell, the sights, the people and so on. There were beautiful birds on the river. So, I dismounted my bike and took a picture of the scene. I felt happy at in that moment. At one time, I always rode the bike in on the weekend along the Han river. I don't often ride a bike these days because I felt am usually too tired. But if I have time, I will go and ride my bike in a few days.

A couple thoughts about the examples you provided: 1. You said: "There's an exception like 'I have no husband.' because I can't have more than one husband." <-- True, but more generally, I would say this applies to any situation where people typically only have one of that thing. Most people only have one husband, of course. But "car" would be another good example, or "house." Most people talk about their car or their house in the singular. Most of the time you wouldn't say "I don't have any cars" or "I don't have any houses." -- you would simply say "I don't have a car." "I don't have a house." Hence, "I have no car." "I have no house." 2. In many of the situations that appear to contradict the countable/uncountable rule, "no" is being used to emphasis "not any" or "not one." This is true for the politician example. "No politician tells the truth." is expressing, "There is NOT ANY politician out there who tells the truth." "NOT ONE politician in the government tells the truth". Of all the politicians out there, not a single one tells the truth. That's why it takes a singular form here. So it might be helpful, in cases where it appears to contradict the countable/uncountable rule, to try substituting "not any" or "not one" for the word "no" in your mind, and see if this solves the problem. Just my two cents. Not sure if this helps.

1. For purposes of business collaboration, -or- For the purpose of business collaboration, 2. ...company A invites The President Mr. X of the subsidiary B Co.,Ltd. of C *and* The Vice-president Mrs.of subsidiary D Co.,Ltd. of C to visit *the* UK... (You need an "and" in the middle to separate the two people, and you need "the" before "UK".) 3. ...for *a* business trip. (You need to include "a" before "business trip")

1. With almost all English verbs, you do not need to use the word "to" before the object. A couple common verbs you must use "to" with are "to give" (I gave it TO him...) and "to say" (I said TO him...) ". But otherwise, you don't. "To ask" is not one of those verbs. This is just something you'll have to memorize, but the good news is that there are only a few verbs where it applies. 2. "People" is already the plural of "person." It is just one of those irregular plurals that does not end with an "-s", just like "women," the plural of woman, and "men", the plural of "man." One person --> two or more people One woman --> two or more women One man --> two or more men In some formal writing, you might hear "peoples" to refer to people GROUPS, like "the peoples of the earth". But this is very uncommon (the only place I can think of where I've seen this is in religious writings).

1- Correct 2- Correct 3- Correct 4- "Plus points" isn't a phrase we use, but you could instead say "One of her strong points," "One of her positive traits," or "One of her positive characteristics." 5- Eighteen hundred, for the same reason that I stated in my comment above: the same rule applies to "hundred", "thousand", "million", "billion", and so on: when it is just a standalone word to express a vague number, as in "Hundreds of dollars", "Hundreds of thousands of people", "Millions of people", "Hundreds of millions of dollars", you use the plural form. But when you attach a specific number to it, it becomes singular. "A hundred." "A thousand." "One hundred." "Three hundred." "Four thousand five hundred." "Eighteen million." "Four billion." 6- Correct, assuming that you mean to be speaking in the present tense. This would be used when listing events one after another, and probably only when predicting events in the future: "The stock market crash sets off a recession. The recession sets off a huge march. Before we know it, the country is in chaos." Most of the time, however, you'll probably hear it in the past tense (when someone is talking about something that really happened, in the news, etc.) "The recession set off huge marches around the country."
