It’s always great to hear news about wildlife returning to where they once lived. For the first time in 8 years the small blue --- British’s smallest butterfly--- has been seen back at a nature reserve in Hertfordshire.

  This nature reserve has had a lot of work done recently in order to help butterflies. Management of the land has included bringing in sheep to keep the grass under control in a more natural way and planting wild flowers for butterfly species. The nature reserve is home to a number of butterfly species. In fact the way that this reserve has been managed means that it is probably the best reserve in Hertfordshire to see butterflies with at least 25 species now living in the area.

There are a number of threats to British butterflies and the greatest threat is the loss of their habitat. Changing farming practice has affected British native butterfly species greatly with many more now being at risk. Butterflies are such an excellent species that they can clearly tell the situation of local environment because they are easily influenced by environmental changes, A wide species of butterflies will generally mean a healthy environment.

The type of land management at the nature reserve in Hertfordshire offers a hope for many species of butterfly to live as usual. Butterflies need all the help they can get at the moment. Although the number of butterflies is beginning to increase, many are still at risk.

閱讀下列短文, 從所給的四個選項中, 選出最佳答案

　Have you ever been afraid to talk back when you were treated unfairly? Have you ever bought something just because the salesman talked you into it ?Are you afraid to ask someone for a date?

　Many people are afraid to assert themselves．Dr．Robert Albert, author of “Stand Up, Speak Out, and Talk Back”, thinks it's because their self-esteem is low． “Our whole set-up is geared to make people distrust themselves, ” says Albert．“There’s always a superior around : a parent, a teacher, a boss---who knows better．　　 These superiors often gain when they ship away at your self-image．”

　But Albert and other scientists are doing something to help people assert themselves．They offer “Assertiveness Training”courses, “AT”for short．In the AT course people learn that they have a right to be themselves． They learn to speak out and feel good about doing so．They learn to be aggressive without hurting other people．

　In one way, learning to speak out is to overcome fear．A group taking an AT course will help the timid person to lose his fear．But AT uses an even stronger motive---the need to share．The timid people speak out in the group because he wants to tell how he feels．

　Whether or not you speak up for yourself depends on your self-image．If someone you face is more “important” than you, you may feel less of a person．You will start to doubt your own good sense．You go by the other person’s label．But, why should you?AT says you can get to feel good about yourself．And once you do, you can learn to speak out．

(1) The problem the writer talks about is that ______．

[　　]

A．some people buy things they don’t want

B．some people are afraid to speak out for themselves or to talk back

C．there are too many “chiefs” and not enough “Indians．”

D．some people don’t think highly enough of themselves

(2) The cause of the problem talked about in this passage is that ______ ．

[　　]

A．some people have a low self-image

B．there is alway someone around who “knows better”

C．salesmen talk people into buying things they don’t want

D．people don’t share enough

(3) The effect of our set-up on people is often to ______．

[　　]

A．make them distrust their own answres to problems

B．make things more favourable for “superiors”

C．keep them from knowing as much as their “superiors” know

D．help them to learn to speak up for their rights

(4) A good title for this passage could be ______．

[　　]

A．Stand Up, Speak Out, Talk Back

B．One Way to Overcome Timidity

C．The Problem of Learning

D．Protect yourself and your family

(5) “AT course” means ______．

[　　]

A．a course which helps you to assert yourself

B．a course in which you will learn the usage of prepositions

C．a course in which you will learn to fight against your enemy and your friends

D．a course which teaches you the knowledge of human life

This is a story  that happened 15 years ago but it has always stayed with me since then.On the way back from work every evening,more often than not there would be a homeless man standing at the exit of the freeway.He always waved at every car,he was always happy and smiling and sometimes almost dancing.Every day after work when I got there，I would quickly roll down my window and give him the coins.Occasionally the red light would be on for a minute and we would ask each other about our day.His answer would always be the same，“I’m blessed！”.

It amazed me that even in his situation of being homeless he was so positive，and his answer would remind me of how blessed I was.A single mother of four amazing kids,with a place to call home and with a job to provide for my kids.Then one day I was called into my boss’s office and was told that I was being laid off due to the economy.Needless to say that on my was home that day I was very sad and upset.I didn’t remember to look for my spare change and keep it ready like I usually did.I wasn’t feeling the joy as I got off the ramp where the homeless man would be.Yet there he was as alway，as l turned the ramp.He set his eyes on me，while still smiling and waving at others.

While I was waiting for the red light to turn，he strolled over to my car.He had a big smile he looked me straight in the eyes and said “today I will give you a dollar”.He then reached into his pocket and pulled out a dollar bill.I was blown away.I burst into tears.I wanted to jump out of my car and hug him！

You see that day he gave me more than a dollar bill，he taught me a valuable lesson.No matter  what material things are taken  from you，no one can take away your choice to be joyful.
