stent or multiple overlapped stents (length ≥ 20 mm) implantation for diffuse atherosclerosis lesions in
octogenarians. Methods Long stent or multiple overlapped stents implantation was performed on 111
diffuse native coronary lesions ( Group O : 47 lesions in 44 octogenarians ; Group Y: 64 lesions in 58 patients
aged under 60) . Baseline demographic , lesion characteristic , angiographic and procedural details were
similar in these 2 groups. Six2month clinical and angiographic follow2up was completed in all cases. In2

Many countries will experience aging populations in the next century because of declining birth and mortality rates. China will soon join their ranks. According to statistics, the aging of China's population will approach its peak by the middle of the next century, with the percentage of the people aged beyond 60 making up 27.4 percent of the total. That means one out of every four people will be elderly.

As for the issue of aging, its situation has been growing increasingly severe in spite of the fact most people are still ignorant of the problems it brings about. Firstly, with families becoming smaller and living pace escalating, it is even graver for families to care for aged members adequately. Secondly, aging causes a relative decline in working force in that fewer people have to support the increasing aged people. Consequently, the productivity of the whole society is affected to some extent. Thirdly and most importantly, the aging of population in China resulted from the successful implementation of family planning has not been synchronized with national economic progress.
　　The rapidity of the population's aging has made it more urgent for the adoption of countermeasures. No doubt they key is to builda solid economic foundation. Meanwhile, importance shall be attached to overall social progress by changing the backward situation in social security, welfare and service. What's more, family care and community services shall also be encouraged.

写英语作文，最重要的是头脑清晰不是吗?就算是到了大学，这一点也不会改变。下面是我给大家整理的大学英语作文，供大家参阅!

A seven day long holiday has flown away. Mourning my happy hours during the vacation, I've been looking forward to winter holidays. People around me seemed to have enjoyed the vacation, too. Then, is it fair that people have the same amount of holidays regardless of their occupations?

Nevertheless, divergent views emerge on the matter in question. Some people are of the opinion that laborers should have the same length of holiday. They hold the view that people are born equal and should be treated equally. The same amount of leisure time may eliminate the unfairness among people who might be upset psychologically if otherwise. At first sight, it may seem to be an attractive idea, but it doesn't bear much analysis.

To begin with, people do different kinds of jobs featuring different labor intensity and so the time needed to refresh their physical condition varies. For example, blue collar workers may work longer hours before they get tired physically, while white collar workers such as doctors and teachers are more mentally stressed. Unable to work continuously as long as those physical labor workers, white collars need more time to pull through the mental weariness than physical tiredness. All in all, people in different jobs assume different responsibilities and have different degrees of pressure.

Secondly, different tasks and duties are required for different professions, resulting in the variety of holiday periods for people in different walks of life. Some employees cannot have their legal holidays and even have to work overtime, such as policemen, construction workers and people in the service professions just can't be interrupted for a mornent;other wise the society will be in a mess. Even for some people in the same occupation, they cannot have the same holidays entitled to them due to many factors out of human control, such as special assignments, and health conditions etc, then not to say people in different fields.

Suppose we, as teachers do, all have three months' holiday in a year. Then factories have to employ considerably more workers because some of them are enjoying happy 's obviously against the principles of doing business at lower cost and efficiency.

If we have only three days off in a year, then all the people in our country will be working day after day. No one can squeeze time to visit those tourist resorts leisurely. It goes without saying that the tourist trade and catering industry thus cannot develop rapidly and healthily.

Last, the development of science and technology allows the ways of work to be changed. Computer experts make their programs, doctors give patients diagnosis and tutors give students instructions at home through optical fabric cable 's how the new term SOHO bore. In other words, the way people work is not fixed so that they need different holiday phases.

Some people need more time to recover from the fatigue of labor. And some people cannot make ends meet though they work for 365 days in a year, for whom holiday is a waste of time.

It is neither possible nor necessary for people with different jobs to have the same amount of holiday off. Holiday is a kind of bonus, just as the Chinese idiom goes, distribution according to

work.

It's a true story in the summer of 1998 when I was attending a youth conference in L. A... and it feels so good to rewind it in the recollection...

Fog swirls, swallowing the car in front of us. Dense, impenetrable, the wall of white throws back the lights into my eyes. There are four of us in a family van that is creeping along the free way from downtown L. A. to Lancaster. Fog gets even stronger and spreads out like a blanket over the flat land. It's Noah's turn to drive with complaints about the couldn't be lower visibility. But he is whispering so that Eugene and Kikki can sleep still. With eyes slightly closed, I am playing Bob Dylan on the disk, whose rhythm echoes the midnight prays.

Well, we've truly had enough prayers just now. Being off from the annual Vineyard Church International Yough Conference, I find myself deeply buried in the ferment that kids create from all over the world. There are cries and whisper, laughter and tears, bless and pain, confidence and disbelief mixed together, building up a confession of the detours of soul. Bible has recorded all this since centuries ago. It's about God, but it's not all time religion.

A boy from Panama asked me if I eat turkey as an Irish Catholic when pastor David was presenting his speech. I smilingly nodded my head and turned back to Mr. David. He is an authentic English with dark blue pupils, eyes right fixing into his listener while talking. He has truly handsome chins that show up his decency of smile and subtleness of wit.

"There is only one door into heaven and Jesus said, 'I'm the door' (John 10: 9), he quoted, "The way you enter is by expressing faith in the Lord Jesus Christ. Faith in Jesus is a commitment to the one whose life becomes your life and his life within you makes you a new person."

There was a dead silence for praying before a burst of weeping broke the ice. A blonde girl threw herself into the arms of the peer beside her, hiding her face. A boy of crew cut on the first row was bending his knees, forehead down to the ground,whispering his regrets. A black girl standing right beside me was shivering her lips with tears hanging up in her eyes, showing a piece of uncertainty. It was truly heart wrenching when more and more kids were peacefully touched by the power of God,harmonizing their words with tears, rather than screaming out their logo as "we love Jesus yes we dm we love Jesus how about you."

It hasn't been long before I am used to the way of praying here in the States. The melancholies in the air soon put me on the way of figuring out the fact lying behind the tears. It numbed me to see the fear and solitude that root deeply in this materially rich world. There is a false security that drastically reshapes the country by drug, crimes, pre marital sex and racism. And it seemed here every tiny little souls were certain victims. Jesus wasn't truly there, but the void became the savior.

It was then that the mother of pastor David rose to sing "Ave Maria". She came up to piano in a gentle pace, took a breath, closed her eyes, and delivered the goods. Well, never have heard the song offered with more feeling, more passion and fervor. She was seventy years old and magnificent. The plain voice flowing in the air was neither scratchy nor dramatic that you might expect from an aging third rate opera singer. This was actually the voice of a grandmother distilling her life into the music to honor what she loved and believed in. when the last lovely note faded and silence held us firm, the "grandma" opened her eyes, smiled at us, and said, "my lord be with you."

That is basically what received from the journey of soul. I told out my sins with once-in-life-time honesty. I may never get a chance to bump into Pastor David and I truly miss this mid aged gentleman of deep sea pupil, although he didn't succeed making me believe that Jesus died on the cross for my sin and paid my sin debt in full.

Noah is now too sleepy to drive. It's my turn to stay awake in this misty of midnight Los Angeles. Fog stands still when we are inching along the road of this spiritual trip. I don't know what keeps me in such a wild and peaceful excitement. Well, if the fog doesn't lift, may we at least have some lines and reflectors put down along the road to guide us.

Lectures and Discussions

提纲

1. 大学里有讲座式和讨论式两种授课方式。

2. 两种授课方式各有利弊。

3. 我的看法。

There are mainly two styles of teaching at universities -- lectures and discussions. Each has its own characteristics.

Lectures are actually the teacher's talk to a class for the purpose of teaching. In this kind of class, the teacher plays a central role, while the students are mainly the listeners. Compared with lectures, discussions are more flexible. Students can examine and argue about a subject with each other in this kind of class. Lectures are especially suitable for big classes hecause it will be easier to keep the students under control, while discussions are typically for small classes for the reason that they are more likely to go out of control.

In a word, lectures and discussions are two quite different styles of teaching, so we should choose either of them or combine them together reasonably according to the circumstances.

Science and Human Beings

提纲

1. 科学使人类进步，生活得更美好。

2. 科学有时也会带来负面效应，如原子能毁掉一切。

3. 就科学与人类的关系谈谈你的观点。

Science enables human beings to progress rapidly and lead a better life. For example, Edison's invention of the light bulb brought our gloomy life to the end and created a bright world for us. Another case in point is Watt's discovery of the steam engine, which triggered the industrial revolution in the western countries, and later all over the world.

Meanwhile, sometimes science does have some side effects. A good illustration of this is atomic energy, which can destroy human beings completdy when used in nuclear weapons.

Anyhow, it is men who develop science. And science, in turn, will do us good in general. As for its side effects, I believe human beings will be rational enough to avoid them or keep them under control.
