哈九中2020-2021学年度下学期4月考 高—英语试卷 2021. 4. 第I卷（选择题，共80分） 第一部分：阅读理解（共两节，满分50分） 第一节（共20小题；每题2分，满分40分） 阅读下列短文，从每题所给的四个选项（A,B,C和D）中，选出最佳选项。 A The best drones （无人机）you can buy right now DJI Mavic Air 2 （$800） DJI Mavic Air 2 offers clear improvements over previous products. It can shoot 4K videos at 60 fps, along with still photos of up to 48 megapicels （白万像素），while the drone's flight time has been increased to 34 minutes （up from 21）. The drone itself starts at $800, but adding the Fly More Combo pack on to your shopping list gives you three batteries and some additional items for another $200. Mavic Mini （$400） Mavic Mini's advantages are its size and weight, the latter of which comes in at just under the 250-gram mark. The biggest drawback is that it doesn't shoot 4K like DJI's higher-end drones, but you'11 still get some impressive 2.7K videos and 12-megapixel still images. Ryze Tello （$110） There may be a handful of clear favorites when it comes to higher-end drones, but things get quite a bit more confusing if you' re just looking for a cheap flyer to try your hand with. While there's no mistaking this for a pro-level piece of equipment, Ryze Tello benefits from a partnership with DJI that gives it some reliable capabilities for the price. DJI Inspire 2 （$3,300） What can professional movie makers get in DJI Inspire 2? A lightweight body, a flight time of 27 minutes, and an amazing 5.2K video quality. Besides, it has retractable （可收回的） landing equipment, and you can turn the camera 360 degrees without anything blocking the view. To fully use DJI Inspire 2, one pilot is needed to pilot the drone and the other to control its camera. 1. What has DJI Mavic Air 2 been improved? A. Its weight and flying range. B.
