10．We have seen that pesticides（殺蟲劑） now pollute soil，water and food，and that they have the power to make our rivers fishless and our gardens and woodlands silent and birdless．Man，however much he may like to pretend the opposite，is part of nature．Can he escape a pollution that is now so thoroughly spread throughout our world？
We know that even single exposure to these chemicals，if the amount is large enough，can cause extremely severe poisoning．But this is not the major problem．The sudden illness or death of farmers，farm workers and others exposed to enough quantities of pesticides is very sad and should not happen．For the population as a whole，we must pay more attention to the delayed effects of taking in small amounts of the pesticides that unseeably pollute our world．
Responsible public health officials have pointed out that the biological effects of chemicals are increasing in amount over long periods of time，and that the danger to the man may depend on the amount of the exposures received throughout his lifetime．For these very reasons people easily take no notice of the danger．It is human nature to shake off what may seem to us a future disaster．"Men are naturally most impressed by diseases which have obvious signs，"says a wise physician，Dr．Rene Dubos，"yet some of their worst enemies slowly come near them unnoticed．"

62．Which of the following can best summarize the first paragraph of this passage？_C
A．Man has a responsibility to bear for what has happened to nature．
B．Possibly man will escape the effects of environmental pollution．
C．Pesticide-caused pollution may also kill people．
D．Man acts as if he did not belong to nature．
63．People do not give enough attention to the delayed effects of exposure to chemicals becauseD．
A．imited exposure to them does little harm to people's health
B．the present is more important to them than the future
C．humans are able to bear small amounts of poisoning
D．the danger does not become seen clearly and immediately
64．Which of the following statements is true according to the passage？_A
A．A person exposed to pesticides even once may get seriously poisoned．
B．Birds are less sensitive to pesticides than humans．
C．The effects of pesticides on humans do not last as long as on fish．
D．Taking in small amounts of pesticides will not cause serious results．
65．We can conclude from what Dr Dubos says thatB．
A．people usually find hidden diseases difficult to deal with
B．people fail to notice hidden dangers caused by pesticides
C．diseases with obvious signs are mostly easy to cure
D．a(chǎn)ttacks by hidden enemies are likely to be deadly．

11．Comparatively few fresh-water species of fishes are limited in their distribution to a single river system，yet not many are found on both sides of a high mountain ridge，such as the Rocky Mountains in North America．That is to say，the fish of the Mississippi Valley are ge nerally different and distinct from those of the Pacific slope．
   While it is a well-known fact that the fish life in no two river systems，even though they empty into the sea on the same side of a divide，such streams do have many species in c ommon．]The principal rivers of the Atlantic slope of the United States，for example，contain several species common to all of them，including the bullhead catfish（鯰魚），the bluegill sunfish and the largemouth bass（鱸魚）．None of these species can endure salt water，so that they cannot now migrate from one river system to another．On the other hand，the more northern streams contain species not found in the southern ones，and vice versa．The common lake，for example，is found in the Atlantic streams from Maryland northward，and the brook trout（蹲魚）and yellow perch（鱸） emerge only in the streams from North Carolina southward．
    How the present distribution came about must remain a matter of conjecture．It is quite probable that some of the streams，including those on opposite sides of a divide，may have been connected at one time．Again，streams may be entirely separate during normal weather，but an exceptionally heavy rainfall or the sudden melting of snow in the uplands sometimes causes floods which may form a temporary connection between them，providing a passage way for fishes．]It is possible，also that water birds may accidentally carry fish or spawn from one stream to another，or that man may be instrumental in such a transfer．
    Evidently，then，fresh-water fishes may become distributed far beyond the confines of the stream of their origin．The chief factor in limiting the still wider distribution of species is temperature．This forms such an efficient barrier that comparatively few species of fresh-water fishes of the United States extend their range into Mexico．In Panama only one fish common to the fresh waters of the States has been found，and that is the eel（鰻），which is not strictly a fresh-water form，as it enters salt water to spawn and is taken in fairly salty water at other times．
32．According to the passage，B．
A．The Mississippi River and the Pacific slope are on the same of the Rocky Mountains．
B．The Mississippi River and the Pacific slope are on the two sides of the Rocky Mountains．
C．The Mississippi River and the Rocky Mountains are on the two sides of the Pacific slope．
D．The Pacific slope and the Rocky Mountains are on the two sides of the Mississippi．
33．In different river systems on one side of a divide，we may findA．
A．fishes of the same species．
B．fishes of the different origin．
C．a(chǎn) few rare fish species．
D．fishes that have the same life．
34．Species，which can't tolerate saltiness，may spread in to another river by the following mechanisms exceptD．
A．being carried by birds                 
B．flooded connections
C．humanity                         
D．spawning in the river mouth
35．Efforts to deliberately transplant the bluegill sunfish and the large-mouth bass into Panama would probably fail due toD．
 A．eels              B．salinity            C．rainfall         D．temperature．

8．Compassion （同情） is a desire within us to help others．With effort，we can translate compassion into actions．An experience last weekend showed me this is true．I work part-time in a supermarket across from a building for the elderly．These old people are our main customers，and it's easy to lose patience over their slowness．But last Sunday，one aged gentleman appeared to teach me a valuable lesson．This untidy man walked up to my register with a box of biscuits．He said he was out of cash，had just moved into his room，and had nothing in his cupboards．He asked if we could let him have the food on trust．He promised to repay me the next day．
I couldn't help staring at him．I wondered what kind of person he had been ten or twenty years before，and what he would be like if luck had gone his way．I had a hurt in my heart for this kind of human soul，all alone in the world．I told him that I was sorry，and the store rules didn't allow me to do so．I felt stupid and unkind saying this，but I valued my job．
Just then，another man，standing behind the first，spoke up．If anything，he looked more pitiable，"Charge it to me，"was all he said．
What I had been feeling was pity．Pity is soft，safe and easy．Compassion，on the other hand，is caring in action．I thanked the second man but told him that was not allowed，either．Then I reached into my pocket and paid for the biscuits myself．I reached into my pocket because these two men had reached into my heart and taught me compassion．

63．The aged gentleman who wanted to buy the biscuitsC．
A．promised to obey the store rules                     
B．forgot to take any money with him
C．hoped to have the food first and pay later      
D．could not afford anything more expensive
64．Which of the following best describes the old gentleman？B
A．kind and lucky                    B．poor and lonely
C．friendly and helpful              D．wise and disappointed
65．The writer followed the store rules becauseA．
A．he wanted to keep his present job
B．he felt no pity for the old gentleman
C．he considered the old gentleman dishonest
D．he expected someone else to pay for the old gentleman
66．What does the writer learn from his experience？B
A．Wealth is most important than anything else．
B．Helping others is easier said than done．
C．Experience is better gained through practice．
D．Obeying the rules means more than compassion．
