1.调整好状态,控制好自我。
1. adjust the state and control yourself.
(1)保持清醒。数学的考试时间在下午,建议同学们中午最好休息半个小时或一个小时,其间尽量放松自己,从心理上暗示自己:只有静心休息才能确保考试时清醒。
(1) keep awake. The math test time is in the afternoon, it is recommended that students have to rest half an hour or an hour at noon. During this time, try to relax themselves and suggest themselves mentally: only resting in quiet can ensure that the exam is sober.
(2)按时到位。今年的答题卡不再单独发放,要求答在答题卷上,但发卷时间应在开考前5-10分钟内。建议同学们提前15-20分钟到达考场。
(2) to be in place on time. This year's answer card will no longer be issued separately, and the answer will be answered on the answer sheet, but the time should be 5-10 minutes before the examination. It is suggested that the students arrive in the examination room 15-20 minutes earlier.
2.通览试卷,树立自信。
2. look at the test papers and build up your confidence.
刚拿到试卷,一般心情比较紧张,此时不易匆忙作答,应从头到尾、通览全卷,哪些是一定会做的题要心中有数,先易后难,稳定情绪。答题时,见到简单题,要细心,莫忘乎所以。面对偏难的题,要耐心,不能急。
Just get the test paper, general mood is more tense, this time is not easy to answer, should be from beginning to end, read all volumes, which are certain questions to be done, the first difficult, stable mood. When you answer a question, you should be careful when you see a simple question. In the face of difficult problems, be patient and not urgent.

数学选择题是知识灵活运用,解题要求是只要结果、不要过程。因此,逆代法、估算法、特例法、排除法、数形结合法……尽显威力。12个选择题,若能把握得好,容易的一分钟一题,难题也不超过五分钟。由于选择题的特殊性,由此提出解选择题要求“快、准、巧”,忌讳“小题大做”。填空题也是只要结果、不要过程,因此要力求“完整、严密”。
Mathematics multiple-choice questions are flexible use of knowledge, and the only way to solve problems is to get results and not process. Therefore, the inverse generation method, estimation method, special case method, exclusion method and combination method of numbers and shapes... Great power. 12 multiple-choice questions, if you can grasp well, easy one minute, one problem, no more than five minutes. Because of the particularity of multiple-choice questions, it is suggested that the multiple-choice questions should be "fast, accurate and skillful" and taboo "making a mountain out of a molehill". Fill in the blank question is as long as the result, do not process, so strive to be "complete and rigorous".
4.审题要慢,做题要快,下手要准。
The 4. question should be slow, the question should be fast, and the next hand is accurate.
题目本身就是破解这道题的信息源,所以审题一定要逐字逐句看清楚,只有细致地审题才能从题目本身获得尽可能多的信息。
The topic itself is the source of information to solve the problem, so the question must be read word by word. Only by careful examination can we obtain as much information as possible from the subject itself.
找到解题方法后,书写要简明扼要,快速规范,不拖泥带水,牢记高考评分标准是按步给分,关键步骤不能丢,但允许合理省略非关键步骤。答题时,尽量使用数学语言、符号,这比文字叙述要节省而严谨。
After finding the method of solving the problem, the writing should be concise, fast and standard, not muddy, and keep in mind that the grading standard of the college entrance examination is divided into steps, the key steps can not be lost, but the non critical steps are allowed to be omitted reasonably. When answering questions, use mathematical language and symbols as much as possible, which is more economical and rigorous than written narration.
5.保质保量拿下中下等题目。
5. guarantee the quality and quantity to take the middle and lower subjects.
中下题目通常占全卷的80%以上,是试题的主要部分,是考生得分的主要来源。谁能保质保量地拿下这些题目,就已算是打了个胜仗,有了胜利在握的心理,对攻克高难题会更放得开。
The middle and lower subjects usually account for more than 80% of the total volume, which is the main part of the test questions and the main source of the candidates' scores. Anyone who can take these questions in quality and quantity can be regarded as winning a battle and winning the mentality of victory.
6.要牢记分段得分的原则,规范答题。
6. should keep in mind the principle of subsection score, and standardize the answer.
会做的题目要特别注意表达的准确、考虑的周密、书写的规范、语言的科学,防止被“分段扣点分”。
We should pay special attention to the accuracy of expression, careful consideration, the standard of writing, and the science of language, so as to avoid being divided into points.
