For conjunctions like never, if they appear at the beginning of a sentence, you can bring the main sentence after the comma to the front when you understand the sentence, so that you can read it clearly.
Unless we deal with our own problems, we will easily become unhappy.
Unless we solve these problems, it is easy for us to be unhappy.
It is that unless we can solve these problems smoothly, we will be unhappy easily.
Such sentence translation is more logical.
Unless, sb can be translated as unless. . . . . . Otherwise, someone will. . . . . . .
If it's C, it can improve the expression of personal feelings.
Although we have solved the problem, we are not happy. /We still feel unhappy.
Generally speaking, we often see such sentences. . . . . . But ... . . . . The front and rear parts form a turning point.
Unless we solve our own problems, we will easily become unhappy.
Unless we can, we will still be unhappy. . . . . . This is a general statement.
If you want to use though, I personally think this question should be more biased towards specific scenario settings.
For example, through the problems we have solved, we are unhappy. /We still feel unhappy.
Although we have solved these problems, we still feel unhappy.
Although we can't solve these problems, we still feel happy.
Although we "failed" to solve these problems, we are still happy.
Many times, when there are several options that seem to have no problems in grammar or even translation, we should choose the best one and the one that is most logical and suitable for the situation, so we choose A.
2. It means a turning point. Later, he said that his writing was very good. Then, in front, he usually says, although he is. . . . Not as good as others
Speak is a verb and needs to be modified with adverbs, so option B is excluded.
A. Speaking is not as good as ... like elder sister, but the writing is good, forming a turning point, and the logic is correct, and then using adverbs to modify verbs, such as ... as for means and. . . . The same. . . . . Grammatically speaking, it is also correct, so choose option a.
C option better is the comparative of good, which directly shows that boys don't speak as well as their sisters, but they write good homework. That's right, and you can't use more to decorate better as a comparison level.
1. When expressing quantity, more can be the comparative form of many or much.
More can be added in front of some polysyllabic words when they become comparative degrees. For example, the comparative degree of beautiful is more beautiful.
3. If the comparative form of a word has appeared, such as better here, then its front can be decorated with some words to express the degree, such as many, far, even, many, a little, a little and so on.
For example, much better, much easier, and much happier means much happier.
For another example, almost is bad, and faster is faster.
Therefore, the C option here should be that this boy is not better than his sister, but his homework is very good.
The d option should be that the boy speaks worse than his sister, but writes good homework.
