第二组Under normal operation, some lubrication oil mist may be discharged from the air compressor to the air start system. This oil may be from excess compressor cylinder lubrication, from faulty oil scraper rings, or may even be suspended oil vapor contaminating the engine room atmosphere and drawn in at the compressor suction. Oil discharge is kept to a minimum by draining the after cooler, air receiver and starting system. If small quantities of lubrication oil do get passed into the starting air system, they will deposit as thin moist film over internal pipe surfaces but are not readily combustible. If a cylinder non-return valve leak while the engine is in operation, some hot gas, possibly with unburned fuel and cylinder lubrication oil, may be blown through the valve to the adjacent air manifold. With further heating from the leaky valve, this, together with the already deposited oil film, will carbonize and form. incandescent carbon. If starting air is applied to the system while still hot, the high pressure air coming into contact with the burning carbon may cause an explosion. Such an explosion will cause a flame to pass back through the air start pipe system, evaporating the deposited oil film and igniting it in the presence of air. Very high velocities and shockwaves are generated which may rupture pipes and fittings.Alternatively, if excessive oil has entered the air start system, a mixture of air and oil droplets may be discharged through the open cylinder non-return valve during starting. This spray may ignite due to high temperatures in the cylinder, causing a flame through the still open valve to the air manifold.To prevent an explosion, air start valves must be correctly maintained and lubricated to ensure correct timing and free movement with positive closing. Oil in the system must be kept to a minimum, pipe lines must be drained and cleaned internally when necessary and oil discharge from air compressors must be kept to a minimum by good maintenance.The passage is mainly aboutA.crankcase explosionB.scavenge box fireC.starting air pipeD.the danger of explosion in the starting air system

In the college-admissions wars, we parents are the true fighters． We're pushing our kids to get good grades, take SAT preparatory courses and build resumes so they can get into the college of our first choice． I've twice been to the wars, and as I survey the battlefield, something different is happening． We see our kids' college background as a prize demonstrating how well we've raised them． But we can't acknowledge that our obsession is more about us than them． So we've contrivedvarious justifications that turn out to be half-truths, prejudices or myths． It actually doesn't matter much whether Aaron and Nicole go to Stanford．
We have a full-blown prestige panic; we worry that there won't be enough prizes to go around． Fearful parents urge their children to apply to more schools than ever． Underlying the hysteria is the belief that scarce elite degrees must be highly valuable． Their graduates must enjoy more success because they get a better education and develop better contacts． All that is plausible--and mostly wrong． We haven't found any convincing evidence that selectivity or prestige matters． Selective schools don't systematically employ better instructional approaches than less selective schools． On two measures--professor's feedback and the number of essay exams--selective schools do slightly worse．
By some studies, selective schools do enhance their graduates' lifetime earnings． The gain is reckoned at 2-4% for every 100-point increase in a school's average SAT scores． But even this advantage is probably a statistical fluke． A well-known study examined students who got into highly selective schools and then went elsewhere． They earned just as such as graduates from higher-status schools．
Kids count more than their colleges． Getting into Yale may signify intelligence, talent and ambition． But it's not the only indicator and, paradoxically, its significance is declining． The reason:
so many similar people go elsewhere． Getting into college isn't life's only competition． In the next competition--the job market and graduate school--the results may change． Old-boy networks are breaking down． Princeton economist Alan Krueger studied admissions to one top Ph．D． program． High scores on the GRE helped explain who got in; degrees of prestigious universities didn' t．
So, parents, lighten up． The stakes have been vastly exaggerated． Up to a point, we can rationalize our pushiness． America is a competitive society; our kids need to adjust to that． But too much pushiness can be destructive． The very ambition we impose on our children may get some into Harvard but may also set them up for disappointment． One study found that, other things being equal, graduates of highly selective schools experienced more job dissatisfaction． They may have been so conditioned to being on top that anything less disappoints．
What does Krueger's study tell us?A. Getting into Ph．D． programs may be more competitive than getting into college．
B.Degrees of prestigious universities do not guarantee entry to graduate programs,
C.Graduates from prestigious universities do not care much ahout their GRE scores．
D.Connections built in prestigious universities may he sustained long after graduation,

资料：Most young people enjoy some form of physical activity. It may be walking, cycling or swimming, or in winter, skating or skiing. It may be a game of some forms, football, hockey, golf, or tennis. It may be mountaineering.
Those who have a passion for climbing high and difficult mountains are often looked upon with astonishment. Why are men and women willing to suffer cold and hardship, and to take risks on high mountains? This astonishment is caused probably by the difference between mountaineering and other forms of activity to which men give their leisure.
Mountaineering is a sport and not a game. There are no man-made rules, as there are for such games as golf and football. There are , of course, rules of a different thing that it would be dangerous to ignore, but it is this freedom from man-made rules that makes mountaineering attractive to many people. Those who climb mountains are free to use their own methods.
If we compare mountaineering and other more familiar sports, we might think that one big difference is that mountaineering is not a 'team game'. We should be mistaken in this. There are ,it is true, no 'matches' between 'teams' of climbers, but when climbers are on a rock face linked by a rope on which their lives may depend, there is obviously teamwork.
The mountain climber knows that he may have to fight forces that are stronger and more powerful than men. He has to fight the forces of nature. His sport requires high mental and physical qualities.
A mountain climber continues to improve in skill year after year. A skier is probably past his best by the age of thirty, and most international tennis champions are in their early twenties.But it is not unusual for man of fifty or sixty to climb the highest mountains in the Alps. They may take more time than younger men, but they probably climb with more skill and less waste of effort, and their certainly experience equal enjoyment.
Mountaineering involves ___.A.cold
B.hardship
C.physical risk
D.all of the above
