语法填空

    How do learning habits influence learning results?It's useful and necessary to discuss learning habits.There is a famous saying "Good habits lead to good endings",{#blank#}1{#/blank#} shows the importance of habits.

    "An apple a day keeps the doctor away." also{#blank#}2{#/blank#} (show) a healthy habit everyday helps to build up our body. Thus,good learning habits can help us gain great learning results,high scores and abundant knowledge{#blank#}3{#/blank#} (include).At first,learning habits form our ways of thinking and{#blank#}4{#/blank#} (attitude) to the content of our learning. {#blank#}5{#/blank#} (obvious),a good habit can help us to speed up to reach our destinations.As we can see,developing a good habit is so important that In would like to introduce one kind of good learning habits—keeping{#blank#}6{#/blank#} learning diary every day. We can start the habit by{#blank#}7{#/blank#} (write) a learning summary and remember to record something impressive and meaningful. Keep it in mind{#blank#}8{#/blank#} gradually we can gain this good learning habit and benefit from it.

    What's{#blank#}9{#/blank#} (much),I find out that I still have some bad learning habits{#blank#}10{#/blank#} well. I can only concentrate on reading for a short time,and I will conquer this problem by spending more efforts on concentration practice.

    I believe that through my efforts,I can gain good learning results by having good habits.

3.解答题(共1题)

5.
如图所示,在竖直平面内建立xOy直角坐标系,Oy表示竖直向上的方向。已知该平面内存在沿x轴负方向的区域足够大的匀强电场,现有一个带电量为2.5×10-4C,质量为0.05kg的小球从坐标原点O沿y轴正方向竖直向上抛出,它到达的最高点位置为图中的Q点,不计空气阻力,g取10m/s2.

(1)指出小球带何种电荷; 
(2)求匀强电场的电场强度大小;
(3)求小球从O点抛出到落回x轴的过程中电势能的改变量.
