It’s you and I who are to blame for the state of the earth. No question about it. It’s our life-style that is threatening life on Earth, so we must make the changes. The good news is that many of those changes are really quite simple, even enjoyable, but for every careful step we take as individuals , we must press government and industry to take a big step on our benefit . And we must start now. Tomorrow’s too late.

My aim this year is to persuade as many of my friends and colleagues as possible to choose the train, and leave their cars behind too. My gardens have been pesticide(杀虫剂)–free zones for years and I enjoy seeing more wildlife on my doorstep as a result; I’ve tried to reduce my contribution to water pollution too, by using environment-friendly, phosphate(磷)–free washing powder , and by no longer thinking of the toilet as a suitable waste-disposal(处理) point .

I ran after a young lady through town recently to give her back the piece of paper she had carelessly thrown away. She disappeared into a shop, and when I followed her inside and made my presentation, she was doubly embarrassed--she worked there, and the boss gave her a ticking–off too. I’ve started asking fellow drivers at gas stations why they aren’t using unleaded (无铅的) petrol . These are small things, but we have to start somewhere, and every little does help .

On May 23,1989，Stefania Follini came out from a cave at Carlsbad，New Mexico.She hadn't seen the sun for eighteen and a half weeks.Stefania was in a research program，and the scientists in the program were studying body rhythms(节奏)．In this experiment Stefania had spent 130 days in a cave,30 feet in depth.

During her time in the cave，Stefania had been completely alone except for two white mice.Her living place had been very comfortable，but there had been nothing to tell her the time.She'd had no clocks or watches，no television or radio.There had been no natural light and the temperature had always been kept at 21℃.

The results were very interesting.Stefania had been in the cave for over four months，but she thought she had been there for only two.Her body clock had changed.She hadn't kept to a 24­hour day，she had stayed awake for 20～25 hours and then had slept for 10 hours.She had eaten fewer meals and had lost 171 bs in weight as a result！She had also become rather depressed(抑郁)．

How had she spent her time in the cave？As part of the experiment she'd done some physical and mental tests.She'd recorded her daily activities and the results of the tests on a computer.This computer had been specially programmed for the project.Whenever she was free，she'd played cards，read books and listened to music.She'd also learned French from tapes.

The experiment showed that our body clocks are affected by light and temperature.For example，the pattern of day and night makes us wake up and go to sleep.However，people are affected in different ways.Some people wake up naturally at 5：00 am，but others don't start to wake up till 9：00 or 10：00 am.This affects the whole daily rhythm.As a result，the early risers are at their best in the late morning.The late risers, on the other hand，are tired during the day and only come to life in the afternoon or evening!

68．Stefania stayed in the cave for a long time because________.

A．she was asked to do research on mice

D．she needed to record her life

69．What is a cause for the change of Stefania's body clock?

A．Eating fewer meals.

B．Having more hours of sleep.

C．Lacking physical exercise.

D．Getting no natural light.

70．Where does the text probably come from ?

Dear daughter,
You are a wonderful person and your mother and I think the world of you. It will not be long before you leave home to make your way in the world. Can I please give you some friendly advice? Here are some things that you should never do.
1. Never Look Down Upon Yourself.
You are great and able to achieve great things so believe in yourself. When things go badly, never stop believing. Some girls get upset, blame themselves and lose self-esteem. All kinds of problems can follow.
2. Never Get Obsessed With Your Appearance.
We think you look great (though some of the clothes you wear worry us!). Please be happy with the person ,you are and the body you have. Eat reasonably, take exercise and be healthy. Some girls show too much concern about losing weight or getting the perfect shape. You look fine.
3. Never Compromise Your Personal Safety.
Never put yourself at serious risk. This means that you cannot trust people until you really know them and that sometimes you have to avoid things that look like they might be fun. Never get drunk or take drugs. Unluckily there are some bad people out there and it is best not to take risks.
4. Never Give Less Than Your Best.
We are very proud of what you have achieved so far. You should be proud too. Keep doing well. Keep trying your hardest at everything you do. No one can ask for more than that.
5. Never Forget That Your Parents Love You.
Whatever happens in life, your family will still be your family. Whatever difficulties you meet with, you can always talk to us and we will try to help. We are here for you.
