必修四第二章平面向量测试题班别 姓名 学号 分数 一．选择题：（

Do the following three main points: 1find out the weak. Review process is to sum up the knowledge on the one hand, make the knowledge more coherent system and regularity, but also let the students themselves, looks up the deficiencies. So, we teachers to understand the students 'knowledge of the situation prior to the review, students not only found widespread deficiencies, but also some shortcomings, for these well designed programs, reasonable arrangement of time, this review is more targeted and more effective. For example, you can design aform for investigation, understanding students 'weaknesses in each knowledge, put it as areview of key, combined with the problem of textbooks to review, both to avoid casting anet tihaizhanshu, and improve the efficiency of review. 2, good collation. Through six years of study, students in the basics, reading method, exercises, and so already have acertain degree of accumulation, the review stage, teachers should know how to guide the students to label the accumulation, process, form asystem of knowledge networks. Exercises for students to be representative, "fine", "complete", to "live", and earnestly do aproblem learning amethod, class of pass was to get "time efficient" review results. 3, pay attention to use. The accumulation of knowledge is ultimately to use, therefore, review the situation and life situation to be created in avariety of languages, guide students on the basis of the previous accumulation of knowledge to use to the maximum, and really apply what they have learned. Second, review the content and strategy of the first part: the basics (a) 1, review the main points of Hanyu Pinyin is able to recite and write down the alphabet of Hanyu Pinyin; accurate spelling pronunciation (after reading cacuminal, nasal sound, light, and retroflex sounds), the correct write consonants, vowels and syllables. 2,. main types according to the order of the alphabet of Hanyu Pinyin alphabetical order; fill in the appropriate uppercase and lowercase letters; see phonetic writing words; pinyin to write sentences with dot to select the correct pronunciation of the word; to bring some initial consonants or vowels, word selection. Second, the main types of words (1) Ruby written words; (2) to bring Word to select the correct pronunciation; (3) use asequencer and radical character lookup method 必修四第二章平面向量测试题 班别姓名学号分数 5=50 一．选择题：（分分） ×10 1. 下列说法中错误的是（） AB ．零向量没有方向．零向量与任何向量平行 CD ．零向量的长度为零．零向量的方向是任意的 2.下列命题正确的是 （） A. 若、都是单位向量，则 ＝ BABCD .=, 、、、 若则四点构成平行四边形 C. 、、 若两向量相等，则它们是始点终点都相同的向量 D.  与是两平行向量 3. 下列命题正确的是（） A、 若，且，则 ∥∥∥ B、 两个有共同起点且相等的向量，其终点可能不同 C、 向量的长度与向量的长度相等 D、A、B、C、D 若非零向量与是共线向量，则四点共线 4.=2 已知向量，若，，则（ ） A1 B.
