这篇文章用英语翻译下,谢谢了

球的训练和比赛中可以有很多不同的投篮方式,但不管哪种投篮方式,有两点是必须做到的:
第一: 从脚底发力,也就是说虽然是用手投篮,但力量是从脚前掌发起,然后通过脚踝、膝盖、胯部、上体、手臂、手腕,最后力量传递至手指尖将篮球投出。力量的整个传递应该是一个连贯协调的过程。
第二:手臂姿势,应该是上臂与前臂呈90度,而手腕后伸也与前臂呈近90度,并与上臂平行。手指持球的后、下部。投篮时,向上、向前伸臂(当然是指向篮框),向上、向前用力屈手腕,最后用手指将球推出,这样投篮会使篮球产生下旋,碰到篮板或篮框不会产生很大的反弹。还应该让手与篮球接触的时间尽量长(即随球动作时间长),这样有利于控制球的运动方向,增加投篮的命中率在开始时不要过多考虑球是否投进了篮框。把注意力集中到身体的姿势、动作以及整个投篮动作的节奏。每次投篮要重复同样的动作要领,正确的投篮动作变得很顺畅的时候,命中率自然会因此而提高。还应该在离篮框不同的位置、角度练习投篮。
四、投篮基本姿势`
单手原地投篮,特别是对青少年来说,是一种基本投篮方式。我们以右手投篮为例:
双手持球置于与眼睛同高的位置,稍便向右侧,右脚比左脚稍靠前,双膝微屈,将球上举,右手手腕后伸,使球体大部分重量落在右手,左手从左侧轻轻扶住球体,脚前掌发力,提起脚跟,伸直双膝,伸右臂将球投出(参考关于投篮) 投篮从手腕向后弯曲开始,进而向上、向前,指尖是最后离开球体的部位。
如何跳投
跳投的好处是不象原地投篮那样容易被对手封盖。青少年选手可能会因为腿、手臂、肩部及背部肌肉力量不足而做不好跳投,那完全可以暂时放弃,否则因力量不足而造成的错误动作会影响自信心,使以后力量达到要求后也难以获得理想的跳投技术。
跳投的技术要领如下:
双手持球,非投篮手置于球前方或侧方(按你舒服的位置放)。投篮手置于球的后部,双膝微屈,双手持球从胸部上移到眼睛上方,然后双脚向上弹跳。跳起时,屈肘(前臂向后),手腕也向后翻。跳至最高点时,前臂前伸,手腕向前、向下将球投出,随球动作(参考关于投篮)要充分,眼睛要始终耵住篮框。

The ball in training and competition can be a lot of different shots, but no matter what kind of shot the way, there are two points must be done: 
First: the soles of the feet from the force, that is, is shooting hand, but the force from the foot before the charge was launched, and then through the ankle, knee, hip, upper body, arms, wrists, and force the final pass from hand to fingertip Basketball cast. The transfer of the entire force should be a coherent co-ordination process. 
Second: The arm gesture, upper arm and forearm should be was 90 degrees, and wrist extension with forearm was nearly 90 degrees, and with the upper arm parallel. Fingers of the ball, the lower part. Shooting, up, forward Shenbi (of course, point to the basket), up, forward wrist flexion strength, the last finger to launch the ball, so that basketball would have a shot backspin, rebounds or face the basket will not be A lot of backlash. It also should be allowed to come into contact with basketball in hand with a long time as far as possible (that is, with the long ball movement), which will help control the direction of movement of the ball, shoot the increase in the percentage of hits in the beginning not too much to consider whether or not the ball dropped into the basket. Focusing on the physical gestures, movements and the movements of the whole shooting rhythm. Each shot to repeat the same action essentials, the correct action shooting is very smooth, the hit rate will be boosted. It should also be in a different location away from the basket, the point of shooting practice. 
Fourth, the basic shooting position ` 
One-handed set shot, especially for young people, is a basic way of shooting. We have the right to shoot as an example: 
Holding hands and eyes at the same high position, then slightly to the right, left foot over right foot slightly forward, knees peg-leg, move the ball on the right hand wrist extension, so that the ball most of the weight falls on the right hand , Caught his left hand from the left side of the ball softly, feet before the hand-fat, filed heel, straight knees, his right arm stretched the ball out to vote (for information on the shooting) wrist shot from the beginning of bending backward, upward and then forward , The fingertip is the last to leave the site of the ball. 
How to jump 
The advantage is that jump shot is not as easy as opponents were sealed. Young people who may be the legs, arms, shoulder and back muscle strength and do not jump enough, it can give up for the time being, or lack of strength as a result of an error caused by the actions will affect the self-confidence, so that power can be controlled after the request has Access to technology ideal jumper. 
Jumper technical essentials are as follows: 
Holding hands, non-shooting hand put the ball in front of or lateral (by you comfortable position release). Shot the ball at the back of the hands, knees peg-leg, holding his hands from his eyes moved to the top of the chest, legs and then bouncing up. Jump up, elbow flexion (forearm back), also back up the wrist. Jump to the highest point, reach the forearm, wrist forward, down the ball out to vote, with the ball movement (for information on the shooting) to the full, his eyes always have to live Ding basket.
