Read the passage. (1) i think that schools should switch from using paper textbooks to using computer tablets. (2) textbooks were effective in the pre-digital age, but now we live in a technology-based society, so schools need to get with the program and adopt a modern approach to learning. (3) in fact, the chair of the federal communications commission said that "it’s time for the next stage” of learning with tablets and pointed out how textbooks are often out of date. (4) opponents argue that tablets aren’t a good choice because initially they’re very expensive. (5) the secretary of education pointed out that tablets can be updated regularly, which saves money in the long run. (6) not to mention the pluses of having the latest and greatest info! (7) many experts agree that switching to tablets is important for the future of education. to improve the logical flow of the paragraph, the best place to move sentence 7 is before sentence 1. sentence 3. sentence 5. sentence 6.

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.

for me this my answer o fortunately, they did not notice, and i could pretend not to care.​   i hope this you
