三、阅读理解
There is no doubt that technology has had a big influence on our lives.People from around the world can now talk to each other almost at once on mobile phones and the Internet.People can easily solve their problems with the help of computers and the World Wide Web.With this technology, it seems that the world is more connected now than ever before.Even so, there have been worries about technology making people feel lonely and disconnected from others around them.
So does this mean that technology makes us lonely
In my opinion, it is hard to say “Yes” or “No”.
It's true that humans need communication with each other.If we depend on technology too much to communicate, this can badly impact our mental health.For me, technology is a tool.And just like any other kind of tool — like scissors, a pencil or a ruler, for example, it depends on how we use it: in a right way or in a right place.Take social media (社交媒体)as an example.If you only use it to compare yourself with others, you might feel sad and lonely.But if you use it as a tool to connect with friends and family or to start a new community to talk about your hobbies and interests, the loneliness will turn into love and friendship.
When you feel lonely after staring at your computer screen all day, maybe you can use that technology to reach out to a reliable (可靠的)friend and invite him or her out for lunch or a coffee.
( )1.According to the writer, what is technology
A.A tool.
B.An influence.
C.A pair of scissors.
D.A way of communication.
( )2.What's the meaning of the underlined word “mental ” in Paragraph 4.
A.Value. B.Future.
C.Mind. D.Brain.
( )3.How may people be, if people use technology too much
A.Sleep less.
B.Live longer.
C.Feel lonely.
D.Get more jobs.
( )4.When we use technology to others, we can find love and friendship.
A.argue with
B.compete with
C.connect with
D.compare with2
