Please help me write a paragraph on my own invetion

We live in time when new technologies and inventions appear almost every day. Our grandparents and even parents could not imagine that these changes would happen in reality, but not in fantastic novels. We cannot realize our world without many of them (just think about living without Internet). Today we can dream of such unreal things as flights to other planets, human and animal cloning, growing organs of our bodies, telepathy, teleportation, etc. and it is not fantasy, as everything we need is time and improving existing technologies.

If I had a chance, I would invent a time machine. The trilogy “Back to the future” was the beginning of this idea. But my time machine should have a shape of a big balloon or a sphere, inside which you could stand and travel to the past or to the future. Being inside it you could see, watch, hear everything and everybody, because the sides of the machine are crystal and clear for you, but at the same time the sphere with you inside must be invisible for the environment and you can influence on nothing.

sentences vary by structure as well as by function. there are compound, complex, and compound-complex sentences.

simple sentence

i like to read.

a simple sentence has one independent clause.

compound sentence

i like to read, and i also like to write.

a compound sentence includes more than one independent clause, connected by a coordinating conjunction (and, but, for, nor, or, so, or yet).

complex sentence

i prefer to read books that are bestsellers.

a complex sentence includes one independent clause and one or more dependent clauses. (a dependent clause is one that cannot stand alone.) types of dependent clauses include relative clauses (i kicked the boy who pinched me), adverb clauses (i am going home now because i have a curfew), and noun clauses (i don't know what to do next).

compound-complex sentence

although i prefer to read current bestsellers, i do like to read old agatha christie mysteries, and i also like some 20th-century science fiction.

compound-complex sentences take a bunch of clauses (multiple independent clauses, and one or more dependent clauses) and toss them together like a salad. although these sentences take practice to write in a grammatically correct fashion, they can hold a tremendous amount of meaning, and are common in academic writing.
