有几句英语, 不知语法是否有问题, 想请沈先生指教。
1. Then let's study：how the light transfer (transforms) from K' into K as well as how the light velocity, wavelengh and frequency transforms from c', λ' and v’ into c, λ and v ?

动词transfer加s就变成名词了, 一般时能用原形动词吗?

2.

We optional fetch a spherical wavefront has regarded the first wavefront. Points A and A' are two intersection points of the first wavefront and x axis. The point A in the east of S and A' in the west of S (as Figure 1). With no loss due to generalization, we will orient the K and K' systems with the x and x' axises pointing along the direction of motion of K' at a velocity of v (v=0, in figure 1；v≠0, in figure 2 ). We will orient these systems so that these axeses x and x' coincide with those of K and K'. The point A, after passing through point B and entering K eastwardly moves ward at a velocity of c, after the time of one second, the number of these lightwaves that these waves passing through a point B entering the K is the promulgating frequency of v', also is the frequency between A and B. Therefore the symbol v' exchanging ought to v_AB .

这一段有什么问题, 英国人能看懂吗? 应如何改正?谢谢
