Are they real English?

[Joe]

I came across these sentences, but I am not sure if they are idiomatic English which are written by native speakers. Could you please give some comments on them? Thank you very much!

1) From what has been discussed above, we may safely draw a conclusion that part-time job can produce a far-reaching impact on students and they should be encouraged to take part-time job, which will benefit students and their family, even the society as a whole.

2) At the same time, along with the benefits of such machines, employees must study knowledge involved in such machines so that they are able to control them.

3) It is hard to imagine a student focusing their energy on textbook while other children are playing.

4) It must be noted that improvement in agriculture seems to not be able to catch up with the increase in population of rural areas and there are millions of peasants who still live a miserable life and have to face the dangers of exposure and starvation.

5) As a popular saying goes, "everything has two sides." Now the public are benefiting more and more from scientific and technological inventions. On the other hand, the progress of science and technology is bringing us a lot of trouble. People in many countries are suffering from public hazards.

I'mon my way out to work, but I'll do the first now and try todo the others later.

This does not sound like a native speaker, but sounds like an advanced non-native. I'd say 'a part-time job', or make it plural. I'd rewrite is as follows:

1) From what has been discussed above, we may safely conclude that part-time jobs can have a far-reaching impact on students and they should be encouraged to take part-time jobs, which will benefit them and their families, and even society as a whole.

Does that sound better?

2) At the same time, along with the benefits of such machines, employees must study knowledge involved in such machines so that they are able to control them.

Again, this reads like an NNES's writing. There is a problem here with 'along with' as it doesn't seem appropriate. I'd say the following:

At the same time, employees must acquire the knowledge to control such machines in order to maximise the benefit from them.

(Or something like that)
