讲解：
1.A This is a hard one to explain because we need to understand several different things about English grammar insgroupsto be able to choose the right answer. In a nutshell, we need a preposition here between the with the head noun and the sentence the surface of metal is first covered with an acid and then inscribed with some sharp instrument.
In other words, the sentence that comes from the adjective clause would look like this:
The surface of metal is first covered with an acid and then inscribed with some sharp instrument in [this] process.
2.Correction: years
Generally speaking, we have two choices here:
for many years
or
many years ago
In other words, we cannot use for and ago together.
Want to know why? Sure you do! It's simple!!
When we have a preposition and a noun together, we have a prepositional phrase. A prepositional phrase is actually one kind of adverb phrase. Are you still with me? We're almost there! So, when we use for and many years together, we have an adverb phrase, right? Right!! Now, ago is an adverb, right?? Right! Therefore, it is redundant (unnecessary) to use ago with the prepositional phrase. Easy, right??? Right!!
3. D Question focus: Correct usage of whose and adjective clauses with quantifiers.
In this question, we want to talk about many of Ayn Rand's novels in the adjective clause. So we have several things happening at once in this question. First, we are are talking about Ayn Rand's, not Ayn Rand. When we need to use the possessive form in an adjective clause, we have to use whose. Next, we need to use a quantifier to talk about a certain portion of the novels. The proper way to use quantifiers is to use the quantifier with of.
4 Correction: occurs in
This one is easy to explain: occurs is an intransitive verb, so it cannot be followed by a noun. When we see this kind of problem on the TOEFL, we can often add a preposition.
5. Correction: it is possible
This one is easy to explain: We are missing the main verb in this sentence. We can add is and everything is fine!!
6. C.Question focus: Subordinate clauses and adverb clauses.
If we look at everything in this sentence, we will notice that we have a verb, loses, that does not have a subject. This is the only answer c |
