Is this looks professional and correct? If it is not, could you correct the mistakes?

Thirdly, will this added bicycle lane result any accident that actually cause more traffic delays than the current set up. The opponents assume that using bicycle beside highway is not dangerous and will not cause any accident. However, this might not be effective solution to reduce the traffic jam in highways. Since, cars might be too fast, and compare to the cars, bicycle could be relatively slow, that’s why speed differences between cars and bikes, and small carelessness of a person might result with severe accidents. The solution advocated by opponents might put people’s lives in danger, if so, it cannot be used to effectively back the author’s argument.

**I'm having a little trouble following your meaning.  It seems like this paragraph is taken out of a longer article?  But I'm going to make my best guess.

Will an added bicycle lane improve traffic delays or actually cause more because of increased accidents?  Proponents say that bicycles next to a highway is not dangerous and will not cause any accidents.  However cars are much faster than bikes and it seems reasonable to argue that small mistakes or moments of carelessness could cause serious accidents.  These accidents would almost certainly cause increased traffic jams.  So not only would this put peoples' lives in danger, but it wouldn't help the traffic problem.

Fabric softener

I have some smells that I don't like. For example, perfumes, cigarette smoke, and fabric softener and so on. I always use odorless fabric softener. Since that is not sold in my city I always order it online.

Climate change is the biggest threat to life on our planet

Question:
Climate change is the biggest threat to life on our planet. How accurate is this statement? Are there any other bigger threats to mankind?

Answer:
Global warming is an existential threat to many living organisms on Earth. This essay will argue that this statement is false because Climate change is a hoax invented by the Chinese, and the biggest threat to life as we know it is an all-out nuclear war with Russia.

Climate change is not real since it was made up by the Chinese government to put economic pressure on American manufacturing. Even though lower labor costs allow China to produce cheaper products compared to the US, they cannot always outcompete their rival due to the lower efficiency of their production lines and inferior quality. To support their economy, the Communist Party created a lie that greenhouse gases are warming up the planet at an alarming rate because they knew that Americans are naive and will not only believe it but will also try to curb the output of their industries to avert the catastrophe. Donald Trump, who is a proven source of reliable information, tweeted the same idea in 2012. [**OMG!  Your English is excellent, but where do you get your information?  Please don't rely on Donald Trump for scientific facts!  For the record, your use of grammar and spelling here is better than his in general.]

A real existential threat to life is a full-scale nuclear war between major powers, which can bring an end to the world as we know it. Among all nations having nukes, Russia stands out because it has the biggest stockpile of warheads, even greater than America. While the relations between the two countries have never been overly friendly, they are at all time low at present. I believe that provocation or a mistake might cause a great disaster. To underline the devastating effects of this kind of weapons on humans, dropping just a few small nuclear bombs on Hiroshima and Nagasaki by the US wiped out several hundred thousand people.

In conclusion, climate change is not a threat because it is not real, and the biggest danger to life is a nuclear conflict with Russia.

**Again, your English is excellent.  I really don't have anything to correct.

smoking

sometimes I can feel the urge to smoke, but after I calmed down I hate it so much.My wish for quitting smoking is getting stronger but meanwhile the eager of smoking is also growing.

Sometimes I can feel the urge to smoke, but in my rational moments I hate it.  My desire to quit is growing stronger, but so is my craving for a cigarette.

**Good luck quitting!

The author is deliberately trying to sound cynical. They believe that all schools produce 'conmen,' but fancier schools just produce fancier conmen. Conmen -> thieves and liars who earn your trust before betraying you Loins - > the part of the body on both sides of the spine between the lowest (false) ribs and the hipbones. Often used to imply the region of the sexual organs, especially when regarded as the source of erotic or procreative power. So you could say a child is a product of his father's loins. So the author is crudely saying the student is a product of the school.

First, it's important that you've actually read all the books that you will be tested on. And beyond that, you want to have spent time thinking about and analyzing the books so you are prepared to answer questions on the exam.

A text about nothing particular

Right now, I am in the library. I have been studying a subject for my master degree for three - four hours and I can't concentrate anymore, so I have decided to write an English text just to practice. I don't know what to write about so I am going to write whatever comes to my mind while I am writing.

Christmas is coming and I swore to myself two years ago that I was not going to spend the whole holiday studying again. However, this winter I feel more overwhelmed than ever, in terms of work, in and my whole life. I hope all this effort pays off in the future. It is difficult to work eight hours each day and study for a master degree and prepare yourself for the TOEFL test while you live 90 minutes far from your job... At least I have assumed that getting a C1 (100 points) this year is going to be impossible so this goal will take longer... I hope to achieve it in around 6-10 months.

I am eating some sweets and the library is emptying out while I am here with my computer. My girlfriend's mother is preparing me a paella for dinner, I hope that it is tasty because I am really hungry although when I go there, I always say that I am not hungry because if I say that I am hungry they give to me too much food. It's like I'm a pig that they have to fatten up to be ready for Christmas dinner.

mmmm Random ideas.

Bye bye.

**Merry Christmas!  I hope you get to enjoy some of the holiday and take a break from studying :-)
