The measure of a good night's sleep is usually based on two things—the amount of time spent sleeping and the quality of that sleep.But now researchers say there is a third thing that matters even more than the other two when it comes to keeping good sleep habits，and that is having a regular bedtime.
   A study has found that going to sleep and waking up at the same time every day have an important effect on one's health.Adults who stick to a regular bedtime tend to weigh less，have lower blood sugar and reduced risk of heart disease.
   The researchers studied the sleeping habits of 2，000 adults with an average age of 69.They found that people with greater irregularity （無規(guī)律） in their sleep patterns tended to go to sleep later at night，feel sleepy and sleep more during the day，and experienced reduced light exposure.These people were also more likely to be stressed.Among the three kinds of sleep problems，sleep regularity was the most strongly associated with health.
   Of course，there are many people for whom this may be impossible，such as night-shift workers or those with late-night duty.But for those who don't have mandatory （強制的） reasons to stay up late，they should make an effort to go to bed at the same time every night.Skip the late afternoon coffee.Get off the phone.Try this calculator to figure out the best bedtime.
   As Matthew Walker，a scientist，wrote， "The shorter your sleep，the shorter your life." Surely that's reasonable enough to go to bed on time.

1．At the beginning of Grade Two，I joined the cross-country running team in our school.
   When I came to the first practice，I was filled with optimism.But as the distance we ran in each practice gradually increased from three to four，to six miles，I realized with surprise that no matter how hard I tried，I wasn't able to run as fast as others.In fact，I was one of the slowest on the team.
   What was the point of putting myself through so much pain？After the first few weeks，I wanted to quit.
   Then we had our first cross-country meet.
   When we started the race，I felt the great pressure of expectations sink onto my shoulders.And after a while I stopped running and struggled to walk up the hill.But then I heard my coaches shouting my name from the top of the hill.I felt confused and embarrassed；why were they cheering for me？I was running terribly!As I tried my best to finish the race，I realized that my coaches didn't care how fast I ran.Neither did my teammates.During the rest of the season，they were always on the sidelines of every race，cheering for me just as loudly as they'd cheered for the front runner.
   From then on，I began to put my effort into supporting my teammates instead of focusing on my own performance.In that way，I celebrated my teammates' victories as if they were my own；I felt their pain and exhaustion as if they were my own.
   Cross-country running made me realize I don't need to be the best to be successful in life.It taught me to value my relationships with people more than my relationship with my ego.It taught me to cheer for others even if I don't know their names.

（1）Why did the author want to give up after the first few weeks？

A．He had much pain in his knees.

D．started caring about his teammates
（4）What did the author realize from his experience？

2．If you are a fruit grower—or would like to become one—take advantage of Apple Day to see what's around.It's called Apple Day but in practice it's more like Apple Month.The day itself is on October 21，but since it has caught on，events now spread out over most of October around Britain.
   Visiting an apple event is a good chance to see，and often taste，a wide variety of apples.To people who are used to the limited choice of apples such as Golden Delicious and Royal Gala in supermarkets，it can be quite an eye opener to see the range of classical apples still in existence，such as Decio which was grown by the Romans.Although it doesn't taste of anything special，it's still worth a try，as is the knobbly（多疙瘩的） Cat's Head which is more of a curiosity than anything else.
   There are also varieties developed to suit specific local conditions.One of the very best varieties for eating quality is Orleans Reinette，but you'll need a warm，sheltered place with perfect soil to grow it，so it's a pipe dream for most apple lovers who fall for it.
   At the events，you can meet expert growers and discuss which ones will best suit your conditions，and because these are family affairs，children are well catered for with apple-themed fun and games.
   Apple Days are being held at all sorts of places with an interest in fruit，including stately gardens and commercial orchards （果園）.If you want to have a real orchard experience，try visiting the National Fruit Collection at Brogdale，near Faversham in Kent.

（1）What can people do at the apple events？

A．Attend experts' lectures.
B．Visit fruit-loving families.
C．Plant fruit trees in an orchard.
D．Taste many kinds of apples.
（2）What can we learn about Decio？

A．It is a new variety.
B．It has a strange look.
C．It is rarely seen now.
D．It has a special taste.
（3）What does the underlined phrase "a pipe dream" in Paragraph 3 mean？

A．A practical idea.
B．A vain hope.
C．A brilliant plan.
D．A selfish desire.
（4）What is the author's purpose in writing the text？

A．To show how to grow apples.
B．To introduce an apple festival.
C．To help people select apples.
D．To promote apple research.

3．One animal which is still alive，but has almost disappeared from the world，is the Chinese river dolphin or Yangtze River dolphin.
   The Yangtze River dolphin is a beautiful animal with a graceful body and a long nose.It is blue-grey with a white underside，weighs between 100 and 160 kilogrammes，and can grow up to eight feet long.It lives in the middle and lower parts of the Yangtze River.Most dolphins live in the sea so the Yangtze River dolphin is very unusual.It is one of only five kinds of river dolphins in the world.
   In the past，there were many stories about the Yangtze River dolphin.One story said that the dolphin was really a beautiful princess who had drowned in the river.Another said it was a kind of horse that could gallop（急速行進）across water，carrying God on its back.
   Sadly，the situation today is very different.Many millions of people live in the Yangtze River Basin and the river is busy，noisy and polluted.The Yangtze River dolphin is almost blind and moves around using sounds.With so many boats and people using the river，the animals cannot find their way around.They are unable to find food，or find each other.Year by year，the number of Yangtze River dolphin in the river becomes smaller and smaller.
   A lot of work is being done to help the Yangtze River dolphin.One section of the river has been made into a kind of nature park，where the Yangtze River dolphin can be safe.Fishermen work together with scientists and tell them when they see a Yangtze River dolphin，or if they find an injured one.Injured animals are taken to a research center and nursed back to be healthy.However，in spite of these measures，scientists estimate （估計）that the number of the Yangtze River dolphin still alive in the river may be less than 100.If things continue as they are，the lovely creature will disappear in the next 25 years.
