May I ask you a question, please help me understand this problem

Single choice and correction can't be so low, these two are the easiest questions to get points, you must strive for a good one, or only 1-2 mistakes.

In this way, I think the reason why your two parts are more problematic should be a basic problem. There is also a matter of judgment, don't rely on feeling to answer the question, to find the law, I suggest you find 100-200 single-choice questions that you have missed before, classify them, see where you are wrong, pay attention to be classified:

For example: consistency (7 wrong).

Past completion is confused with present completion (10 wrong).

Subjunctive mood (5 wrong).

Infinitive, participle, gerund confusion (15 wrong).

Clause antecedents, etc. (10 errors).

To divide the categories in this way, and then start from the part that you have made the most mistakes, find a grammar book to learn it, ask if you don't understand, anyway, to understand it completely, and then classify it, such as: the most wrong is the subjunctive mood, and the most wrong in the subjunctive mood is (the one that is the opposite of the past facts) and then find a question to do, and practice in a targeted manner.

Start with your own mistakes and improve, and you will make great progress.

The single-choice test mainly tests collocations and grammatical knowledge.

The phrases in the test are basically in the textbook, pay attention to accumulation.

As for grammar, I don't know if you are in high school or junior high school, but if you are in junior high school, you should pay special attention to prepositions and conjunctions, adverbs.

Attention should also be paid to the conjunctions of the clauses. (Clauses are particularly important, study hard) and know your good luck! （^

The single choice mainly focuses on grammar and vocabulary, and you should memorize and understand more, after all, diligence can make up for the shortcomings.

These 2 points you are afraid of will be very common in college in the future! So you have to lay the foundation now! I had this problem when I was in high school too! I'm constantly practicing, and I've improved. You better stop speculating and practice more. Yourself is the most reliable.

1. Yes.

2. For more purchased travel content, it is recommended to read the instructions for purchasing goods carefully, or you can call the corresponding ** or contact customer service to understand what else needs to be paid and prepared for additional services.

3. Be sure to carefully read the detailed description of the purchased service, for example, this Hainan double tour is "to Haikou with a group", that is, the cost of travel between your home and the meeting place in Haikou is borne by yourself. What you buy is just a multi-day travel service in Hainan after entering the group in Haikou.

4. Finally, be sure to read the description carefully many times, such as the content included, or according to the usual travel experience, compare what other necessary services or content do not include self-pay.

Hope the above helps.
