E）任务型阅读（共5小题，计10分）阅读下面的短文，根据短文内容，完成表格。（每空填1至3个词）China has decided to stop the use of free plastic bags. Supermarkets， shops and outlets(经销店) in China can’t offer plastic bags any more.Every year， people use too many plastic bags. They throw them here and there after they have used them. The government has done its best to deal with them but failed. While we offer quick service（服务） to customers， the plastic bags pollute water，earth and air， and they waste the oil. The government asks people to go back to carry cloth bags and use baskets when they go to buy something. The cloth bags and the baskets can be used again and again.Many months have passed. The environment has been improved a lot.ActionMake a decision to stop the use of 41.42.Supermarkets， shops and outletsAdvantageOffer43. service to customersDisadvantagePollute water， earth and air and waste44.What should we doGo back to carry cloth bags and use 45.41.__________

考题
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
