It used t be mstly the military(军队) that used small, unpilted aircraft, called “drnes”．The little planes were very cstly.But as they have drpped in price mre peple have begun t use them.Rescue wrkers and farmers are amng the new users.Mviemakers are using drnes t film frm the sky.Histrians use them when they explre ancient buildings.Rescue wrkers use them t lk fr peple.And nw farmers are using them t watch ver their crps.
Rmain Farux is a French businessman wh starts cmpanies.His father was a farmer.He believed drnes culd help farmers.He helped create a cmpany that develped a small drne that culd be cntrlled by peple n the grund.They called it “Agridrne”．It uses a special “ptical sensr” t examine crps.He says the technlgy used is similar t that used by smartphnes — except it has wings.
A cmputer prgram directs the drne t fly ver the crps.The sensr n the drne recrds fur different­clred “bands” f sunlight that are reflected ff the crps.
Jean­Baptiste Bruggeman is a farmer.He says the drne flies ver his crps at different times f the seasn.And this prvides a lt f infrmatin abut his crps.The drne pictures shw him the exact amunt f fertilizer the crps need.It als shws exactly where the fertilizer is needed.Sme areas f a field may need mre than thers.
As a result, Mr Bruggeman says there is reduced nitrgen frm the fertilizer after the harvest.This helps nature.Rmain Farux says farmers use infrmatin gathered by the Agridrne t place fertilizer nly in areas where it is needed.Befre they used the drnes, farmers wuld put the same amunt f fertilizer everywhere.
Drnes als save time because farmers can examine up t three hectares in abut a minute.

Ⅱ.阅读七选五
Many diseases are caused by things ut f ur cntrl.Dctrs urge us t eat healthy fds, get exercise, stp smking and limit ur alchl intake. 1 And it is free and easy — smiling!
When we smile, the brain wiring gets altered.The chemicals that are released are mre psitive.Smiling is a first step in fighting stress and its harmful effects n human health.
The main cause f heart attacks and strkes is the blckages in bld vessels (血管). 2 The mst cmmn reasn fr these blckages is a build­up f fatty depsits n the inner walls f the arteries (动脉).When we feel stressed r under pressure, ur bdy releases many natural hrmnes including adrenaline and crtisl.When we are stressed fr a lng perid, these stress hrmnes are ever­present in ur bdies.And that, medical researchers warn, may lead t health prblems.
3 Hwever, they claim that when peple are stressed fr lng perids f time, they may nt make the best decisins abut what t eat.They may vereat, smke r drink t much alchl.They may nt get enugh exercise r sleep.And all f these can lead t health prblems.
Dr.Chckalingam says a smile may be ne way t help.He tells his patients t smile 20 times an hur.T sme, that might seem like a lt f smiling.Or sme might even feel flish — smiling fr seemingly n reasn. 4 It is nt invasive (开刀的) like a surgical peratin.It is free and it has n side effects.
Once we smile, we are relaxed.This relaxatin directly lwers bld pressure, imprves sugar levels in the bld. 5 And it just may prvide a little extra prtectin fr everyne's heart health.
A．But a smile des nt invlve drugs.
B．But there is smething else we can d.
C．Experts say we can cntrl and even prevent them.
D．These blckages prevent bld frm flwing t the heart r the brain.
E．And they are the number ne cause f death arund the wrld.
F．If we are smiling, we are breaking that link between stress and health prblems.
G．Researchers say the link between stress and the heart disease is still unclear.
语篇解读：本文是一篇说明文。许多疾病是由我们身体里的某些东西失去控制而引起的，我们可以通过微笑来避免这些疾病的产生；当我们微笑时，大脑会释放有益的化学物质；微笑是对抗压力给人们的健康带来的有害影响的第一步。
1．选B 空前表述许多疾病都是由身体里的某些东西失去控制而引起的，医生敦促我们吃健康的食物、锻炼、戒烟以及限制酒精摄入量，并结合空后一句可知，B项“但是我们可以做其他事情”符合语境，衔接上下文，故选B项。
2．选D 空前表述血管中的堵塞物是心脏病和中风的主要原因，空处应是说明堵塞物的害处，故D项“这些堵塞物阻止血液流向心脏或大脑”符合语境，空前的“the blckages”与D项中的“These blckages”相呼应，故选D项。
3．选G 根据空后一句“Hwever，they t eat.”可知，G项“研究人员说压力和心脏病之间的联系尚不清楚”符合语境，故选G项。
4．选A 空前讲到一个医生告诉他的病人一个小时笑20次，有人可能觉得那好像太多，也有人可能甚至觉得荒唐；空后讲到微笑不像外科手术一样需要开刀，它是免费的，而且没有副作用。由此可知，此空应填一个表示转折的句子，故选A项。
5．选F 根据语境可知，F项与前后句内容相衔接，应是讲微笑的好处，故选F项。

参考范文：
As far as I'm cncerned, rganic farming is preferable t chemical farming.Here are sme reasns.
Firstly, in rganic farming, farmers are frbidden t spray chemical pesticides n the plants, s there are n pesticide residues left n them and the fds are healthier and safer.Secndly, farmers use natural waste frm animals, which will be gd fr imprving the cnditin f the sil and reduce envirnment pllutin.
All in all, I'm in favur f rganic farming.
