5、（1）17世纪之前，人类局限于初等数学，即几何，三角学和代数，那时只考虑常数。Before 17th century, man confined himself to the elementary mathematics, i.e., geometry, trigonometry and algebra, in which only the constants were consider

6、ed.（2） 两个整数的和、差或积是一个整数，但是两个整数的商未必是一个整数。 The sum, difference, or product of two integers is an integer, but the quotient of two integers need not be aninteger.（3） 设X是线性空间V中k个元素组成的一个线性无关集合，L(X)是由X张

7、成的子空间。那么，L(X)的每一个元素都可以表示成X的元素的线性组合。Let X be an independent set consisting of k elements in a linear space V and let L(X）be the subspace spanned by X, then each element of L(X) can be expressed as a linear combination of element of X.（4）若P(A)>P(B)，则称事件A比事件B有更大的可能性；如果P(A)P(B),则称事件A至少和事件B的可能性一样大。The

8、 event A is called more likely than B if P(A)>P(B), and at least as likely as B if P(A) P(B).（5）微分方程的研究直接受到力学、天文学和数学物理的推动。The study of differential equations has been directly inspired by mechanics, astronomy, and mathematical physics.（6）由定义导数的过程所提供的几何解释以一种自然的方式导出了关于曲线的切线的思想。The procedure used to

9、 define the derivative has a geometric interpretation which leads in a natural way to the idea of a tangent line to a curve.（7）一个复值序列收敛当且仅当它的实部和虚部分别收敛。A complex-valued sequence converges if and only if both the real part and the imaginary part converge separately.（8） 几何主要不是研究数，而是形，例如三角形，平行四边形和圆，虽然它也

10、与数有关。Geometry mainly studies not numbers but figures such as triangles, parallelograms and circles, though it is related with numbers.四、英译汉1、 Two events are said to be mutually exclusive when both cannot happen at the same time.If E denotes an event,then the event that E does not happen is called th

11、e complementary event of E,and is denoted by .Obviously,E and are mutually exclusive.Since an event either happens or does not happen,the sum of their probabilities is 1. 两个事件若它们不能在同一时间都发生时我们称这两个事件是互斥的。如果 E 表示一个事件，然后 E 不会发生的事件称为 E的补充性事件，并由表示。很明显，E 和是互斥的。因为对于事件发生或不发生，其概率的总和是 1。2、 Thus pq is true if b

12、oth p and q are true or if both p and q are false.The following are English-language equivalents to pq : “ p if and only if q”,”p is a necessary and sufficient condition for q.”and “p precisely if q.”It is worth emphasizing that the compound proposition pq and its converse qp are quire different;the

13、y have different truth tables.因此 pq 是真的，在 p 和 q 同时为真或 同时为假时成立。以下是英语语言描述，等同于pq : "p当且仅当 q"，"p 是 q 的必要和充分条件"和"p 准确如果 q."值得强调的是复合命题 pq 和它的逆命题 qp 是不同的，他们有不同的真值表。 3、 We now introduce a natural generalization of partial derivatives.In the definition of ,the numerator of the d

14、ifference quotient used involves the value of at two points and .As approaches zero,the first point approaches the latter along the line y=.For a point approaches along the line x=.We now replace these two special lines by an arbitrary line through .我们现在介绍的偏导数的自然推广。由中的定义，所使用的差商的分子涉及在和两个点的值。当接近零，第一点沿

15、直线y =接近后者。对于点沿直线x =趋向。现在我们通过一个任意经过点的线来更换这两个特殊的线。4、 The whole numbers have many important subsets.A whole number is said to be even if it is divisible by 2;2,6 and 18 are example of even numbers.A whole number is said to be odd if it is not divisible by 2;1,7and 13 are examples of odd numbers.The nat

16、ural numbers greater than 1 and called prime or composite.A number is prime if it is divisible only by 1 and itself.A number is composite if it is divisible by a natural number other than 1 and itself.整数集有很多重要子集。当一个整数可以被2 整除时,我们通常称它为偶数，例如 2，6 和 18 是偶数。当一个整数不能被2 整除时,我们通常称它为奇数，例如 1，7和 13是奇数。对于那些大于1的自然

17、数 ，可以相应称为素数和合数。数A是质数，如果它是只能被 1 和自身整除。数A是合数，如果它能够能被 1 和本身以外的自然数整除。5、 Some-where in the process of solving a firstorder differential equation ,an intrgration is required to remove the derivative and in this step an arbitrary constant C appears.在解一阶微分方程的过程中，为了消去导数，需要在某一步进行积分，这时候就出现了一个任何常数。6、 A matrix with the same number of rows and columns is called a sqare matrix.And an n th-order square matrix,which is denoted by ,consists of numbers with n rows and n c
