Sentence check

[Silverobama]

Dear teachers.

Here are some sentences from my notebook. I wrote them down many years ago. They are mainly from my old dictionaries. Some of them do make sense and good and some are not. I want to keep the good ones. Please feel free to take a look at them. You might simply put a cross next to the wrong ones but it would be better if it/they can be corrected.

1) He borrowed a mechanical book from me.
2) The two ends of the pipeline are connected with the radiator.
3) The car has a fan-cooled radiator.
4) A centipede snaked swiftly away.
5) A train snaked into sight.
6) We must make use of our untapped reservoirs of talent.
7) The lightning made a zigzag in the sky.
8) The road zigzagged up the hill. (I think "zigzag" is common as a verb but not as a noun.)
9) He played the cornet in the school band.
10) It was thought that the fire alarm had been set off as a prank.
11) The tongue is a vocal organ.
12) Today the young are much more vocal.
13) She could be wayward, petulant, and disagreeable.
14) He meditated for two days before giving his answer. ("meditate" is weird here to me.)
15) They picketed the restaurant.
16) The price of sugar has suddenly skyrocketed up.

Dear teachers. Hello.

Here are some sentences from my notebook. I wrote them down many years ago. They are mainly from my old dictionaries. Some of them do make sense and are good, and some don't and are not. I want to keep the good ones. Please feel free to take a look at them. You might simply put a cross next to the wrong ones but it would be better if it/they can be corrected.

1) He borrowed a mechanical book from me. What on earth is a "mechanical book"?
2) The two ends of the pipeline are connected with to the radiator.

See above.

How many sentences can I ask per time or how many word counts do I have per time?

Maybe it's still a good idea to ask in "Ask a teacher"?

Thank you so much, ems, I wrote down all your suggestions in my new notebooks.

Edited:

What on earth is a "mechanical book"?

I don't know but according to its Chinese meaning, it means "a book about mechanics". I already deleted the sentence.

I wonder if today we could move on to sentence 3 and 4. Or I have to start a new thread with two sentences each.

ask each time, not ask per time.
A mechanical book conjures up images of a book operated by machine.

[emsr2d2]

Please start a new thread for sentences 3 and 4 (but number them 1 and 2 in the new thread). I recommend you stick to two sentences per thread, otherwise the responses can get very muddled. Put them in "Ask A Teacher".

Two things, Silver. One, how can both ends of a pipe be attached to the radiator? Two, do you translate everything into Chinese?

No, that's not my translation but someone else's.

As for the radiator thing, I think it makes sense.

I've seen many impossible things in Western countries possible in China.

Yeah, right! You're bluffing.
Prove me wrong by posting a reliable source that supports your statement.

[Tarheel]

I've seen many things that are impossible in Western countries but possible in China.

Like a pipe that starts and ends at a radiator?

[Tarheel]

What is different in China? Are the laws of physics (for example) different there?
