from how fast you are going to how accurate your shot angles are.With a Bluetooth chip inside，the basketball can connect to your smartphone and tell you in the voice of a coach to “snap your wrist”or “go faster”，depending on the data.The hovercraftThanks to the Californiabased companys product Hendo，flying past your friends on a floating board could soon become a reality.The hovercraft has 4 small engines.These create a special magnetic field which produces enough force to lift the board off the ground.At the moment，the hoverboard(悬浮滑板)can only float an inch off the ground for 15 minutes and must fly over a metal material.Its expensive too，at $10,000，but the company hopes that one day the technology could be used.Wireless electricityMost of us could not bear to live without wireless Internet.We use it every day for everything from our phones to our cars.But one company wants to go a step further by combining wireless technology with electricity.Thats right，no more

grow._4_The forest greatly helps in the reduction of the air pollution.Trees are responsible for the production of oxygen and absorption of carbon dioxide._5_ It is there for a reason just like everyone else on this planet.There cannot be a better way to restore the balance of nature than to increase the forest area.We must remember that the forest is a natural habitat of wide variety of animals and plants.In this manner, there is no substitute for reforestation.AAnd global warming will speed up the destruction of forests.BKeep in mind that you cant just plant the seedlings anywhere.CRecreations wont work until all these details have been considered.DSo a good plan is needed to make the reforestation a successful one.EThe forest also protects us from typhoons and other

planted.(一些额外的树，而不是土生土长在该地区的也还需要种植。)”，再根据下文“The importance of having multiple species of trees is considered to make sure that the needs of other species that will live and grow in the area are met.(拥有多个种类的树木的重要性被认为是确保满足将生活和成长在该地区的其他物种的需要。)”这些都反应出其他树在该地区的成长很重要。3Dthe plan是承接之前提出的，对此做以解释，故可知上文提到plan，故选D。4B上文“This is to ensure that they wont cover each other while they grow.”意为“这是为了确保当他们长大时，他们不会相互遮掩住。”这句话是对之前的计划目的的说明，故可推知接下来，作者再次强调注意间距问题，故选B。5E结合上文“The forest greatly helps in the reduction of the air pollution.Trees are responsible for the production of oxygen and absorption of carbon dioxide.”可知，森林大大有助于减少空气污染，树木是负责氧气的生产和二氧化碳的吸收。由此可知这是指森林的好处之一，故选E。.短文改错假定英语课上老师要求同桌之间交换修改作文，请你修改你同桌写的以下作文。文中共有10处语言错误，每句中最多有两处。每处错误仅涉及一个单词的增加、删除或修改。增加：在缺词处加一个漏字符号()，并在其下面写出该加的词。删除：把多余的词用斜线()划掉。修改：在错的词下划一横线，并在该词下面写出修改后的词。注意：1.每处错误及其修改均仅限一词；2只允许修改10处，多者(从第11处起)不计分。Dear
