6.The rates of hydrolysis and/or degradation of entrapped particulate pollutants are unlikely to be very rapid and particalarly as such processes for many common particulate pollutantscan occur both aerobic and anerobic conditions,it must be assumed,for cases where degradation is complete in the areation tank,that it will continue to occur in the clarifier.

are unlikely to be very rapid意为“未必很迅速”as such processes指代hydrolysis and/or degradation

“被夹带的粒状污染物的水解与降解未必很迅速,特别是对许多普通的粒状污染物这样的过程能在好氧和厌氧两种条件下发生,应设想:对于在曝气池中降解不完全的情况,在澄清池中降解将会继续发生。”

The automobile engine is an internal combustion engine because the fuel (gasoline) is burned inside it. The burning of gasoline inside the engine produces high pressure in the engine combustion chamber .This high pressure forces piston to move, the movement is carried by connecting rods to the engine crankshaft. The crankshaft is thus made to rotate: the rotary motion is carried through the power train to the car wheels so that they rotate and the car moves. What do we see from the first paragraphs? ( ) The engine is source of power for a car. The engine can not make wheels go around. The engine is resource of oil. Which one Statement is true according the above first paragraph? ( ) The automobile engine is an international combustion engine. The automobile engine is an external combustion engine. The automobile engine is an inner combustion engine What do we see from the second paragraphs? ( ) High pressure is source of power inside a engine. Crankshaft is rotated without any force. Combustion chamber is not a part of the engine. Which one Statement is true according the above second paragraph? ( ) The movement of piston is carried by connecting rods to the engine crankshaft.

All three judges on the show Sunday praised 23-year-old Liu Wei for his determination, urging him to keep on pursuing his dreams, and the Beijing native said he would try quipping(说俏皮话), "At least I have a pair of perfect legs." For winning the Chinese version of Britain's Got Talent, Liu will be invited to play as a guest performer with Taiwanese singer Jolin Tsai. He also has the chance for a performing contract.
