Imagine the following scenario(情景): A woman buys her lunch every day from a fast food outlet near her job. After some years, she finds herself 30 pounds overweight, and feeling unhealthy. So what does she do? She chooses to bring a lawsuit against the fast food outlet, claiming that the food served there was the cause of her being overweight and in poor health.

Sounds ridiculous, doesn’t? The only thing more absurd than the story itself is the fact that is not fiction. There are people who have sued(控告)fast food chains for causing their weight problems.

This is an example of one of the ways in which many of us spend enormous amounts of energy trying to deny the undeniable and universal fact that we are all ultimately responsible for our own choices and our own lives.

How much easier would we make it for ourselves if we could accept this fact rather than resist it? But how can we embrace the truth, that we are living the lives we choose to live, that we are enjoying or suffering the consequences(结果) of our own choices, and that blaming others for our problems and shortcomings is nothing more than a comfortable fantasy?

We must acknowledge the truth of our lives, however unpleasant this may be. If we are overweight, in a bad relationship, in a dead end, we need to accept that this is where we are, at this moment in time.

Imagine that woman decided that she was unhappy with the extra pounds she’d gained after many years of eating fast food on a regular basis. Imagine that this woman took the time to really understand and accept that she and no one else was responsible for her eating choices. Having acknowledged this fact, she then decides to make the changes in her lifestyle to become the healthier, slimmer person she wants to be.

小题1:What would be the best title for the passage?

A.Be responsible for Our Own Choices.

B.Overcome the Challenges in Our Life.

C.Acknowledge the Truth Rather than Deny It.

A.To show the right way of dealing with weight problems.

B.To describe a familiar scenario in life.

C.To give support to the author’s viewpoint.

D.To compare the consequences of different choices.小题3: What can we learn from the first paragraph?

A.Fast food chains contribute little to people’s overweight problems actually.

B.Fast food outlets are responsible for many people to become overweight.

C.Many people tend to blame others for their own problems.

D.The author himself is a supporter of fast food chains.小题4: What should a person do if he is in a bad relationship with his roommates, according to the author?

A.Acknowledge the truth of his life and let it be.

B.Think about what’s wrong with himself and then put it right.

C.Accept that this is where we are and wait for things to improve.
