All dreaming starts with sleep.When we sleep there are four stages（階段） that we go through.
Stage One is the lightest stage of sleep.In this stage of sleep someone can be awakened by low sounds or slight touch.Stage One sleep happens through- out the night.It，often reappears as a transitional state of sleep following arousal（ 刺激） during the night.When Stage One does reappear during sleep.jye.ai only lasts- thirty seconds to one minute.Young adults spend ten to fifteen minutes a night in Stage One sleep.
Stage Two sleep may have some of the slower eye movement of Stage One，but in general Stage .Two sleep is free of any eye movement.Another feature of stage two is arousal.Since Stage Two is a deeper sleep than Stage One，it will take more arousal to awaken a person from this stage of sleep.
Stage Three sleep as well as Stage Four is usually referred to as a slow wave sleep，which basically means a slow frequency（頻率） of brain thought.There are no visual eye movements in this stage.Again in Stage Three it takes even more arousal then Stage Two sleep，to awaken a person from this state of sleep.Most of the dreams remembered take place during stage Three Sleep.
Stage Four sleep is the deepest of sleep.This is where the body and mind gets the most rest.Brain frequencies increase slightly in Stage Four sleep.In this stage of sleep people begin their dreams.When a person is dreaming you can visually tell by the movement of the eyes.Scientist measure deep sleep by "R.E.M." which simply means "rapid eye movement".What they measure is the amount of time your eye moves in Stage Four sleep and also brain activity along with frequency.Once again much more arousal is needed to awaken a stage four sleeper.

1．According to a recent report，about 15% of the people in the UK are members of gyms.But are they more likely to be fit？
A study found that gym members were 14 times more active than people who didn't belong to any health club.Gym members did six hours more exercise a week，and this activity did make them fitter than non- gym members.They also spent less time sitting down every day than non- gym members.The results were the same for men and women.
The study included 405 people between the ages of 30 and 64，and the main characteristics of those who were gym members were the same as those who were not. "But gym members did more training than non-gym members，" said the lead author，Elizabeth Schroeder of the University of Illinois.While it might seem clear that gym members exercise more and are healthier than non-gym members，Schroeder says this has not been directly shown before.However，the study is only designed to show a tie between gym membership and more exercise.It may be that active people like to join gyms.In the study，people who exercised as much as gym members were also in good health.
You can get the same benefits wherever you exercise.This study shows a gym membership can make you do more exercise，but other research shows that exercising outside has other help.Outdoor activity can make you feel happy about life，especially if you run through a forest.
Outdoor exercise is also more interesting than going to the gym.The first five minutes of outdoor exercise is especially helpful in making people feel good.But Schroeder says that a gym may also encourage greater exercise because it can be social and fun.
（1）What did the new study find out？
A．British people are crazy about the gym.
B．Gym exercise is better than outdoor exercise.
C．Gym membership can make us healthier.
D．Gym is necessary for our daily life.
（2）In the study，researchers studied.
A．people between aged 30 and 64
B．the same number of men and women
C．405 gym members
D．people with the same characteristics
（3）The study is aimed to build a tie between and .
A．a(chǎn)ctive people；more gym exercise
B．more exercise；health
C．gym membership；more exercise
D．happiness；more exercise
（4）Which statement will Elizabeth Schroeder agree with？
A．Women should do more gym exercise.
B．We should be careful with outdoor training.
C．Outdoor exercise is better than gym exercise.
D．We may make great exercise if we go to the gym.發(fā)布：2025/1/5 9:30:5組卷：1引用：1難度：0.2 -
2．Is it possible to have a diet that s both healthy and friendly to our planet？Here are answers to your eco-friendly food questions.
Does what I eat influence climate change？
Yes.The world's food system is responsible for about one quarter of the planet -- warming greenhouse gases that humans produce each year.That includes raising and harvesting all the plants，animals，and animal products we eat，as well as processing，packaging，and shipping food to markets all over the world.

In general，beef and lamb have the biggest climate footprint per gram of protein while plant- based foods like beans，rice，corn and wheat have the smallest influence.Pork，chicken，eggs are somewhere in the middle.

Studies have shown that people who eat a meat-heavy diet can reduce their food- related footprint by one third or more by moving to a vegan diet- no meat，dairy，or eggs.If you don't want to go that far，just eat less meat.
Can I really make a difference to our planet
We need more food to feed the world's growing population.One person alone can make only a tiny djye.aiference.If many people make changes to their diets，that will start to add up.It will make a greater difference if the world's heaviest meat eaters make some changes to their diets.
