The 40th anniversary congress of reform and opening up has been held recently and I think it’s important.

Comment: when verbs follow "will", they are not conjugated.

* John will play (not "plays")

* He will win (not "wins")

Comment: When referring to a nationality that ends in -ese (Chinese, Sudanese,  Japanese, etc.), the word "the" is placed before it.

* ...it will remind Canadians / it will remind Australians / it will remind Salvadorans

* ...it will remind the Sudanese / it will remind the Chinese / it will remind the Japanese

After 40 years, China has achieved much progress but we shouldn’t deny the fact that we are now actually in a state very much like sailing to the midstream of a river or climbing halfway up a mountain, as the goings get tough, we must press ahead and there’s no turning back.
Moreover, from the congress we know the targets we should fulfill in the next stage. For example, now China tends to improve its infrastructural level from “made in China” to “created in China”and to “intelligent manufacturing in China”. As a result, China now master the leading technology of small unmanned aerial vehicle, high-speed rail.

If you say, "China now is mastering the leading technology...", it means that they are in progress of doing so.

If you say, "China now masters the leading technology...", it means they are currently masters of it. 

Travelling

I have traveled many times, however , the trip which left the deepest impression on me was when I traveled to Nanjing by myself in my sophomore year.

so I share two things about the trip to with you.

Comment: It might be just a dialectal thing, but "share with" sounds idiosyncratic when you're talking about sharing experiences or physical items, and "share to" is used when you share something on social media

the first one It is a delightful thing. I was sitting on a train to Nanjing, meeting a grandmother who was over 80 years old, I helped her taking  luggages take luggage,then,she gave me a box of sugar to thank me.she told me a lot of things about her experience when she was young. I can feel her health 、kindhearted and lifeful, she is my role model in life.

Comment: "luggage" is an uncountable noun, so it doesn't have a plural form.

Comment: to help + (someone) + verb (in its base form). 

* I helped my friend exercise.

* She helped me understand the theory better.

* We'll help you design your bedroom.

the second one is an irritating thing. when I was visiting " The Memorial Hall of the Victims in Nanjing Massacre by Japanese Invaders" a visitor hugged a statue with a smiling expression to take a picture. My God. could you imagine , the statue that of a mother who was is killed by Japanese Invaders ,but she hugs a baby who he is still alive ,crying in the arms of his mother, when they seen such a sad scene. why are they laughing. I can't understand.

"The zoo has no useful purposes"

"One of the most dramatic cases that I watched on "YouTube " was about a child who inadvertently fell out of his mother's hand into the gorilla cage of gorilla. At the first moment, the gorilla held him softly and was trying to settle him down,"

Notes:

- hold (present tense) = held (past tense)

- to settle down = to calm down

"So, she started to play with him as she is used to do normally does with her babies by holding one of his feet and dragging him around."

Note: the plural form of a noun is used when preceded by "number + of", even if the number is "one".

- two of my fingers

- one of my ideas

- eight of her teeth

- one of her songs

"Anyway, it was a final choice made by her. For protecting the kid, the keeper had to shoot her. So it's not so funny to put the life of animals at risk of due to irresponsible, reckless and curious people."

"Some argue that the zoo gives the best way for education because it provides vivid information about the behavior of animals. However, the zoo doesn't isn't like jungles and forests. Then Thus,, this unnatural environment may lead to artificial responses. Moreover, technology provides us with another creative ways which are better than the zoo like 3D documentary movies."

Note: "another" is used with singular nouns. "other" is used with plural nouns.

- another idea / other ideas

- another dog / other dogs

- another game / other games

There is something really motivational to learning a language: Seeing your own progress after a long period of studying. 

Comment: When a verb without a subject comes after a preposition, the -ing form is used. To negate a verb in this context, just add "not" before it.

- I stretch before running.

- He won the game by playing hard.

- He won the game by not quitting.

- She cooks without using salt.

- She is going to write about not being able to sleep.

As you guys could imagine, it didn't work. My college classes are back and I won't be able to accomplish my appointments...
It was very frustrating for me. Although I wanted so much to learn a new language so much, I put it in my mind that this would be difficult ...

Comment: You need to put "to" between "want" and the following verb.

Comment: In English you cannot put an adverb ("so much") between the verb ("learn") and its object ("a new language"). 

I finished watching the series “YOU” recently. The leading man is Penn Badgley who had started starred in “Gossip Girl”. 

He falls in love with the leading woman in the first gaze then begins to tracking and overseeing her.

------

Comment: You can say "begin to + verb" or "begin + verb+ing" but not "begin to + verb-ing"

- She began to cry. (correct)

- She began crying. (correct)

- She began to crying (incorrect)

------

He did a lot of crazy things because he wanted to protect her but it was did not made make sense! He thought she will would appreciate him for everything.

------

Comment: The past tense version of "will" is "would" (one of the various usages of "would") when "will" occurs in a subordinate clause (this is when a verb phrase acts like an object: "he knows English / he knows I speak English)

- I know that he will come to the party! / I knew that he would come to the party!

- She is guessing that the LA Lakers will win the championship / She guessed that the LA Lakers would win the championship

------

He thought that he did everything for Love.

But she never requested anything.

He killed her in the end because he realized that she’ll would never love himself again after understanding everything he had done.

I thought this series is was weird,creepy but attractive.

But I am not interested in the next season.

"These days, traffic in our cities is growing and pollution as well. Nevertheless, some people use cars in a careless way. Furthermore, there are countries where it is very difficult breathing to breathe, such as China, and also the numbers of death for cancer is increasing because of air pollution."

Comment: You could say: "there are countries where breathing is very difficult" or "there are countries where it is very difficult to breath"

- If you put the be-adjective phrase (be difficult) before the verb (breathe), then you will use the "to" verb form (to breathe): "where" + "it" + "be" adjective + "to" verb 

- If you put the verb before the be-adjective phrase, then you will use the "ing" verb form (breathing): "where" - verb-ing + "be" adjective 

- "There are times when winning is not fun." / "There are times when it is not fun to win."
