　　(2016·郑州第二次质量预测)The year 2017 saw smart people always busy inventing useful things，which have helped to make the world better，smarter and a little more fun.Now，let's take a look at some of the inventions.

　　Super banana

　　Australian biogeneticist(生物遗传学家)James Dale visited Uganda, a poor African country，in the early

　　2000s，where he found that 15%­30% of children under 5 were at the risk of going blind because they didn't get enough vitamin A．Dale also learned that people there love bananas.They eat 3 to 11 bananas a day.So he came up with an idea to plant bananas containing added nutrition in order to improve Ugandans' health.With the help of Bill Gates' foundation，Dale developed the “super banana”．He added a gene to the fruit，making it rich in vitamin A.

　　Coaching basketball

　　Basketball is popular worldwide，partly because you only need a hoop (篮框)and a ball to play the game.But this simple game experienced a technology makeover with the development of a smart sensor basketball.

　　The ball，called the 94Fifty Basketball，has 9 sensors inside.They can tell you anything 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 hovercraft

　　Thanks to the California­based company's 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.It's expensive too，at $10,000，but the company hopes that one day the technology could be used.

　　Wireless electricity

　　Most 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.

　　That's right，no more tangled(缠结的)wires and no more having to sit and hold your cellphone near a power socket(插座)in the corner of the room.WiTricity，a US company，has invented technology that can power objects up to 2.4 meters away.It uses a special plug­in coil(线圈)that creates a magnetic field!

　　(2016·双鸭山模拟)

　　Reforestation

　　Around the world there is an increase in the demand for reforestation.This is because the consumption of the forests has affected not only the animals living in the area but also the people.And reforestation is about the rebuilding of the forests that have been severely destroyed.It can offer a lot of benefits when the recreation is successful.

　　__1__ This includes collecting seedlings(幼苗) that are native in the area to make sure that there is a natural reconstruction of the area.Some additional trees which are not native in the area also need to be planted.__2__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.

　　Destroying a forest is easy but rebuilding it is really hard.__3__ The plan must include accurate spacing on plants and trees.This is to ensure that they won't cover each other while they 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.

　　A．And global warming will speed up the destruction of forests.

　　B．Keep in mind that you can't just plant the seedlings anywhere.

　　C．Recreations won't work until all these details have been considered.

　　F．There are many things to be done when it comes to this type of effort.

　　G．It is important to make sure that they are suited to the climate and the type of soil.

　　【答案】　1－5　FGDBE

　　【语篇解读】　本文围绕重新造林来提醒我们要保护好森林，森林带给我们人类很多益处。

　　1．F　文章第一段提出重新造林这一概念，再结合include一词可推断出要做许多事情。

　　2．G　根据上文“Some additional trees which are not native in the area also need to be 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。

　　3．D　the 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。

　　4．B　上文“This is to ensure that they won't 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。

　　5．E　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。
