請把以下中文翻譯成英文。
評定運動員的起跳技術主要看以下幾點:
1.助跑和起跳的結合是否緊密,協調,能否最大限度地利用助跑中獲得的水平速度.
2.起跳的速度和幅度,及上板的准確度.
3.應有適宜的騰起角度和踏板的制動力較小.
評定運動員的騰空技術主要看以下幾點:
1.無論是何種騰空技術動作,都必須能夠保持身體在空中的平衡.在落地前能夠做到高抬大腿腿,前伸小腿.
2.騰空階段必須保持抬頭挻胸姿態.正確完成空中技術動作.
3.挻身式必須必挻胸展髖,使髖部前移,不能挻腹.走步式交換步的動作要在身體重心下方,兩大腿進行剪絞交換,整個動作協調,自然,有效.
場地器材
用于跳遠助跑的跑道,寬度為1.22~1.25米.長度不得短于40米.助跑道左右傾斜度不得超過1:100,跑進方向的總斜度不超過1:1000.
用于跳遠起跳的白色標誌板為跳板.起跳板應為長方形,長為1.21~1.22米,寬度為20厘米,厚度為10厘米.一般是木料制作.
跳皮靠近沙池落地區一端的邊緣為跳限制線.一般用紅線和沙台標出.比賽時,如果運動員腳部在起跳中踩過起跳線即為犯規,成績無效.
落地區是跳遠起跳騰空後的落地區域,一般為填滿鬆軟沙子的坑.沙坑的最小寬度為3米,沙坑的遠端與起跳板的距離不得短于10米.
始 ：用力蹬地，兩臂大幅度擺動。
開始方式 1. 半蹲式和站立式 ( 穩定性高 )。
2. 進行間起跑 ( 輕鬆自然，步長不穩定 )。
中段助跑 ：上身正直或稍前傾，用力蹬地，擺動腿向前上方擺動，用腳前掌落地。
最後幾步 ：積極加速，節奏輕快。
倒數第二步 ：步長要長，減少腳落地制動。
最後一步 ：步長要短，速度快。

✔ 最佳答案
Assessment of the athletes off technology mainly depends on the following points:1 . whether the combination of approach and takeoff closer co-ordination , can maximize the use of run-up to get the horizontal velocity .
2 . off the speed and magnitude , and accuracy on the board .
3 . should have the appropriate flight angle and the pedal braking force smaller .
Assessment of the athletes vacated technology mainly depends on the following points:
1 . No matter what kind of vacant technical movements , the body must be able to maintain a balance in the air . opposeth and exalteth can do in the thigh before landing leg , protrusion leg .
2 . the flight phase, the rise of Shan chest posture must be maintained . the right technology to complete air movement .
3 . Yan Yan chest body type to develop will be hip , so hip forward , not Yan belly . walk step -type switching center of gravity moves to the bottom of the body , two legs for scissors exchange , the motor coordination , natural and effective.
