Ladies and gentlemen,
Thank you for attending our company’s news
conference. As you know, with the development of
economy, people have to face various pressure. They
don’t have enough time to attend to the old in their
family, which has become a prominent social
problem. To solve this problem, our company put out
the household robot, which is designed to take care
of old people. It can cook meals at a fixed time which
can be adjusted according to individual needs. It can also accompany old people in having a chat, playing chess and doing exercise. Moreover, it can deal with emergencies. For example, if an old man falls ill suddenly, the robot will call doctors for help.
It would be a great help for you if you own such a robot.
Thank you.

Many freeways have been built across China in the past few years.
过去几年已建起了横跨中国的很多条高速公路。
2. 现在完成时的被动语态的注意点。
(1)带有双宾语的动词, 如give, send, make, show, bring, teach, write, take, sell, buy, tell, lend, pass, promise等, 变为被动语态时, 可将其中一个宾语变为主语, 另一个保留不动。

如遇双宾语, 最好变间宾; 如若变直宾, be done后加to。
(2)带有复合宾语的动词变为被动语态时, 只能将宾语变为主语, 原来的宾语补足语改为主语补足语, 原来省略to的作宾语补足语的不定式, 被动语态中要加to。
