如图所示，竖直放置的两块很大的平行金属板a、b，相距为d，ab间的电场强度为E，今有一带正电的微粒从a板下缘以初速度v0竖直向上射入电场，当它飞到b板时，速度大小不变，而方向变为水平方向，且刚好从高度也为d的狭缝穿过b板而进入bc区域，bc区域的宽度也为d，所加电场大小为E，方向竖直向上，磁感强度方向垂直纸面向里，磁场磁感应强度大小等于E/v0，重力加速度为g，则下列关于粒子运动的有关说法不正确的是
A．粒子在ab区域的运动时间为
B．粒子在bc区域中做匀速圆周运动，圆周半径r=2d
C．粒子在bc区域中做匀速圆周运动，运动时间为
D．粒子在ab、bc区域中运动的总时间为

| Recently I paid a visit to Harvard University, where there are top class scientists and professors and the best academic system in the world. I was very 1 when I first stepped onto the campus (校园). Well, it's not even really a campus. It's 2 like an area in a small town. Harvard's main buildings are from the 18th century. They look very old and 3 . You might 4 say they're a little shabby (破旧). They don't fit the modern 5 of university at all. The buildings are surrounded by 6 and trees, so I felt as if I had walked into a castle of the Mid-Ages. But when I looked across the street, the 7 shops and in-fashion (时尚的) students made me feel like I was in the 21st century 8 . It creates a strong contrast (对比) and brings a special 9 to the school. Our tour 10 Gary took us around and told us."You see this grass field in the center of the school? Here is where they hold their 11 ceremony. They just set up tents and benches and have a very simple ceremony." It's 12 ! Who would think the most talented students just graduate on the grass? I 13 some students put a blanket on the grass and lie down to read a book. When I listened to the soft sound of 14 turning, along with the singing of the birds, I felt very 15 . There was no competitive feeling at all. Harvard has the world's first computer in its science centre 16 there are hundreds of high-end computers, too. Its religion(宗教) and the literature departments are also 17 the best. It is the perfect mix of tradition an d 18 technology. It makes Harvard a very attractive place to 19 in. I hope one day I'll 20 my dream school-Harvard. | ||||
