Nowadays，people everywhere seem to find less and less time available to them, and more and more things to achieve. It’s quite common to find people running around like headless chickens meeting deadlines that they create. One doesn’t have to live this way, in stress and struggle. 1.

We can do some gratitude list making right on the spot to get out of our heads and away from all that we wished we had but don’t, and to be thankful for all that we do have. I swear learning how to do this will relax you in a way that will change your life for the better.

科目：高中英語(yǔ) 來(lái)源：2016屆山東德州高三上學(xué)期期末統(tǒng)考英語(yǔ)試卷（解析版） 題型：閱讀理解

I saw a dear friend a few days ago and stopped by to ask her how she was doing．She looked up，voice lowered，just complaining：“I'm so busy…h(huán)ave so much going on”

Almost immediately after，I ran into another friend and asked him how he was．Again，the same tone，the same response：“I'm just so busy…got so much to do．”

Their responses knocked me down．How did we create a world in which we have more and more to do with less time for leisure，less time for reflection，less time for community? When did we forget that we are human beings，not human doings? What happened to a world in which we can sit with the people we love so much and have slow conversations with meaningful pauses and silences that we are in no rush to fill?

This disease of being “busy” is spiritually destructive to our health and well-being．It weakens our ability to be fully present with those we love the most in our families, and keeps us from forming the kind of community that we all so desperately tong for．

I don’t have any magical solutions．All I know is that we are losing the ability to live a truly human life．I am always a prisoner of hope, but I wonder if we are willing to make a change to our so-called busyness of life．Somehow we need a different model of organizing our lives，our societies，and our families．

I want us to have a kind of existence where we can pause，look each other in the eye，touch one another，and ask ourselves：Here is how my heart is doing，I am taking the time to reflect on my own existence，and I know how to express the state of my heart．

1.What’s the result of the busy lifestyle?

A．People will become forgetful in their everyday life．

B．People are beginning to find some time for leisure．

C．People may lose the ability of enjoying their life．

D．People will further understand the importance of community．

2.How can we live a relaxed and balanced life according to the author?

A．By seeking help from local families．

B．By improving our working ability．

C．By reconstructing the model of our lives．

D．By creating a smarter open community．

3.Calling himself a prisoner of hope，the author means that .

A．he thinks people won’t change

B．he actually has magical solutions

C．it is harmful to have many hopes

D．he is always optimistic about life

4.What is the purpose of the author writing the article?

A．To express concerns about people’s complaints．

B．To criticize and reflect on the people’s present lifestyle．

C．To voice his opinions on how to live a simple life．

D．To question whether it is possible to live a slow life．

Liverpool city council want to clear the city of fat pigeons. They say that people are feeding the birds, which makes them fat. The pigeons get bigger because their normal diet would consist of seeds and insects, not high-fat junk food they are eating in the city centre.

The council want people to know that everyone who feeds the pigeons is responsible for the streets being so crowded with these birds. They hope to encourage the birds to move away from the city centre and into parks and open spaces.

Ten robotic birds have been brought into the city centre to scare the pigeons away and visitors are asked not to give the pigeons any food. The mechanical birds - known as “robops” - will sit on the roofs of buildings. They can be moved around to different locations. They look like a peregrine falcon, which is a bird that kills pigeons. They even make noises and flap their wings to scare the pigeons. They hope that the pigeons will go away before the city becomes the European Capital of Culture in two years.
