There are some reasons: 1. To communicate with someone, you use some parts of your body to get your points across. In real life situation you use your hands, face, eyes, head, shoulders etc. in order to be as clear as possible. For example, you wave your hand to attract a person, keep a straight face to show that you are serious, wink an eye at your friend to convey some shared secrets, nod your head to show your understanding, and shrug your shoulders when you don't care about something. 2. You use your eyes to lip-read when your ears fail to get the words clearly. 3. Naturally when you hear someone talking, unconsciously, you search for the person. It is as if there was something missing that annoys you. 4. With video chat becomes more enjoyable. 5. Some people are perverts; they are not looking for language partners.

Unrequited love is love that you feel for someone but that they do not feel for you.

Paleontology

Hello everybody! Could you please correct the following TOEFL essay?

The passage states that woolly mammoths became extinct due to the climate change and overhunting by predators and provides three reasons. However, the professor refutes each of these reasons.

First, the passage says that warming the earth global warming caused problems for mammoths as they had been insulated with thick wool to be protected them against frigid weather. The professor denies this, explaining that there is no evidence suggesting that warming the earth global warming has caused their extinction. The mammoths could have moved to the poles as their skeletons have been found at areas close to the poles.

Second, the passage mentions that mammoths were had been hunted by animals. Again the professor counters this, saying that there were not any predators animals for mammoths. She says that sober-toothed tigers were at the same size of the today’s lions, but their teeth were one third as strong as one third those of the lions. So, they couldn’t frequently have frequently hunted mammoths.

Finally, the passage states that mammoths were had been overhunted by human tribes. However, the professor refutes this, saying that we cannot judge mammoths were had been hunted by human the tribes just because knowing we know that wandering human tribes were good at hunting. They could have hunted Buffalos buffalo and Beers bear that were easier to hunt.

Although the passage states that mammoths became extinct by the combination of climate change and over hunting overhunting, the professor believes that this hypothesis has a lot of problems and it is hard to believe it.

I tried to be as correct as possible, but I think I am subject to some mistakes.

First notebook entry: Introducing myself

I'm learning English 'cause it's very necessary.

Actually in English we don't have a one-to-one equivalent for "چندمین ". But when we use it, it should be contextualized. That is, considering what we are trying to say we should utilize different words, phrases, and contexts. Where did he stand in the succession of managers of the institute? او چندمین مدیر موسسه بود؟ Where is your city listed in order of economical importance? شهر شما از نظراهمیت اقتصادی چندمین است؟ ''In order of" or "in ... order" , in phrases such as "in order of priority", "in order of  importance", and "in order of size", and "in alphabetical order", "in chronological order ", and in numerical order" respectively, are good phrases to be used with ''چندمین '' as their translation when used in questions. I hope this helps!
