1. It is working in  teams instead of on my own that       

and made my work more efficient.   (free)

是團(tuán)隊(duì)運(yùn)作而非我單打獨(dú)斗使我免入困境并工作得效率更高。

 has freed me of trouble考查時(shí)態(tài)的運(yùn)用和free的用法。free sb. of sth.，將某人從某事中解脫出來。若強(qiáng)調(diào)句主句中用一般現(xiàn)在時(shí)，則從句用與現(xiàn)在相關(guān)的時(shí)態(tài)；因其后有并列連詞and同made 連接，故用現(xiàn)在完成時(shí)。

科目：高中英語(yǔ) 來源： 題型：

Today just as technology changed the face of industry, farms have experienced an "agricultural revolution". On the farm of today, machines provide almost all the power.

One of the most important benefits will be the farm computer. A few forward-looking farmers are already using computers to help them run their farms more efficiently. The computers help them keep more accurate records so they can make better decisions on what crops to plant,how much livestock(家畜) to buy,when to sell their products, and how much profit they can expect. Many computer companies have been developing special computer programs just for farmers. Programs are being written for pig producers，grain farmers，potato farmers，and dairy fanners. In the future， farmers will be able to purchase computer programs made to their needs. Because of the growing importance of computers on the farm，students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses. There can be no doubt that farmers will rely

on computers even more in the future. While the old-time farm depended on horse power,and mod?ern farms depend on machine power, farms of the future will depend on computer power.

Another technological advance which is still in the experimental stage is the robot,a real "mechanized hired hand" that will be able to move and,in some ways,think like a human being. Agricultural engineers believe that computer-aided robots will make shocking changes in farming before the end of the century. Unlike farmers of the present，farmers of the future will find that many day-to-day tasks will be done for them. Scientists are now developing robots that will be able to shear (修剪) sheep，drive tractors，and harvest fruit. Even complex jobs will be done by robots. For example， in order to milk their cows,farmers must first drive them into the barn,then connect them to the milking machines，watch the machines，and disconnect them when they are finished. In the future， this will all be done by robots. In addition，when the milking is completed，the robots will automatically check to make sure that the milk is pure. The complete change of the farm is far in the future,but engineers expect that some robots will be used before long.
