I think an afterno
3、on in fife open air will do us good, dont you? Would you like to come with us?“ I had already made an appointment with the hairdresser but I weakly agreed to cancel it. Mrs. Brown smiled graciously. “I shall be making some cakes this afternoon,“ she explained, “so I shant have any free time. I wonde
4、r whether you would mind doing some shopping for me during your lunch hour, that is, if you can fit it in.“ She handed me a typewritten list made up of twenty-four separate items, from shrimps to sugared almonds, including an order for a chicken, four sliced loaves, a half-litre of fresh cream and s
5、ome Camembert, all to be delivered at the house before five o clock. That still left me with plenty to carry myself, and it seemed that if only I could manage to stagger home with my load, there would be no danger of starving the next afternoon. That evening a violent thunderstorm broke. Rain poured
6、 down; the sky was split by terrifying flashes of forked lightning while peals of thunder drowned conversation. But Mrs. Brown was not upset. “It will have cleared up before morning,“ she prophesied. “When this storm has passed we It have ideal weather, you 11 see. The B. B. C. weather forecast has
7、promised sunshine, and they don t often make mistakes.“ She was right. The following morning was glorious. Early in the morning I could hear her moving about in the kitchen. Breakfast was late and consisted of corn flakes and toast. “I must apologize for neglecting you,“ said Mrs. Brown. “So much to
8、 do ! You wont mind making your bed this morning, will you7 Im so busy. Im afraid we shall have to make do with cold meat and potatoes for lunch.“ The whole morning seemed to be spent in loading the car with a variety of bags, baskets and mysterious parcels. After a lunch of cold mutton, boiled pota
9、toes, and limp damp lettuce, we took our rain jackets and umbrellas and fitted ourselves into the car. I was in the back seat, squeezed uncomfortably in the midst of a mountain of equipment. We crawled for the next two hours along a main road where a line of traffic was wedged so tightly together th
10、at it was almost stationary. Mr. Brown was in charge of the steering wheel but Mrs. Brown controlled the driving. At last we turned down a narrow lane and started looking for a suitable place for tea. Each one that we saw had its drawbacks: too sunny, too shady, too exposed, too sheltered. “If we we
11、re to picnic there, we should be too hot, cold, conspicuous, shut in,“ declared Mrs. Brown as she inspected each in turn. At last she decided that a certain meadown ( in reality no different from ally other meadow we had examined) would do. Mr. Brown opened the gate and drove the car inside. We star
12、ted to unload. I had never in my life realized that so much stuff could be required for a simple picnic. A folding table was produced together with a clean glossy tablecloth, folding chairs (with cushions), enough crockery and cutlery for a banquet and more than enough food for six courses, paper na
13、pkins, a transistor radio, half a dozen illustrated magazines and even soap, a towel, water and a bowl for washing our hands after the meal. I half expected a crimson carpet, possibly footstools for our feet, with red candles as tasteful table decorations. I did discover a tin of fly killer, a bottl
14、e of ammonia for the treatment of stings and even some indigestion tablets. For a whole hour we made our preparations and at last everything that we needed was ready. As we were enjoying our first mouthful of thermosflask soup, a stout man opened the gate and came towards us. “Sorry to make a nuisan
15、ce of myself, but in five minutes we shall have finished milking the cows,“ he announced. “Theyll be coming back here directly after.“ Mrs. Brown gazed at him speechless for a moment. At last she found words. “But you can see weve only just started eating,“ she protested indignantly. “surely you can
16、 delay sending them in for an hour or so?“ “Sorry maam, weve other jobs to do. Well give you time to clear up: that s the most that we can allow. Say twenty minutes. You know youre trespassing, of course?“ Mrs. Brown seemed to collapse in her chair. I wished I were fifty miles off. Mr. Brown was the
17、 only one that accepted the situation philosophically. “It seems to be high time we departed,“ was his only comment. Half an hour after we moved off as the cows were wandering down the lane and as the first drops of rain were falling. We joined the traffic jam in the main road. Three hours later we
18、unpacked again and had our picnic in Mrs. Browns dining-room-with a carpet underfoot but still no candles. We were strangely silent but our deep sense of grievance did not in any way prevent us from eating a great deal. （分数：71.00）(1).The author was most probably a tenant of the family. （分数：7.10）A.YB

36、 it is not (36) 1to telephone someone very early in the morning. If you telephone him early in the day while he is shaving or having breakfast, the time of the call shows that the matter is very important and requires (37) 2attention. The same meaning is (38) 3to telephone calls made after 11:00 p.m
37、. If someone receives a call during sleeping hours, he (39) 4its a matter of life and death. The time chosen for the call (40) 5its importance. Time plays a very important part in social life. In the U. S .A. guests tend to feel they are not highly regarded if the invitation to a dinner party is (41
38、) 6only three or four days before the party date. But it is not true in all countries. In other areas of the world it may be (42) 7foolish to make an appointment too far in (43) 8because plans made for a date more than a week away tend to be forgotten. The meaning of time differs in different parts
39、of the world. Thus, (44) 9; promptness is valued highly in American life, for example. (45) 10. In the U.S. no one would think of keeping a business friend waiting for an hour; it would be too impolite (46) 11. （分数：10.00）填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_七、
40、Reading Comprehensio(总题数：2，分数：355.00)The idea of a fish being able to generate electricity strong enough to light lamp bulbs-or even to run a small electric motor-is almost unbelievable, but several kinds of fish are able to do this. Even more strangely, this curious power has been acquired in diffe
41、rent ways by fish belonging to very different families. Perhaps the best known are the electric rays, or torpedoes(电鳐), of which several kinds live in warm seas. They possess on each side of the head, behind the eyes, a large organ consisting of a number of hexagonal shaped cells rather like a honey
42、comb. The cells are filled with a jelly-like substance, and contain a series of flat electric plates. One side, the negative side, of each plate, is supplied with very fine nerves, connected with a main nerve coming from a special part of the brain. Current passes from the upper, positive side of th
43、e organ downwards, to the negative, lower side. Generally it is necessary to touch the fish in two places, completing the circuit, in order to receive a shock. The strength of this shock depends on the size of the fish, but newly born ones only about 5 centime-tres across can be made to light the bu
44、lb of a pocket flashlight for a few moments, while a fully grown torpedo gives a shock capable of knocking a man down, and, if suitable wires are connected, will operate a small electric motor for several minutes. Another famous example is the electric eel. This fish gives an even more powerful shoc
45、k. The system is different from that of the torpedo in that the electric plates run longitudinally(纵向) and are supplied with nerves from the spinal(脊骨) cord. Consequently, the current passes along the fish from head to tail. The electric organs of these fish are really altered muscles and like all m
46、uscles are apt (likely) to tire, so they are not able to produce electricity for very long. The power of producing electricity may serve these fish both for defense and attack. （分数：177.50）(1).It can be seen from the passage that_.（分数：35.50）A.the capacity to generate electricity is the distinctive ch
47、aracteristic of the fishB.the current travels in an upward direction from the positive side to negative side in torpedos electric cellsC.some fish can produce enough electricity to drive a number of electric motorsD.the torpedo s electric cells have a shape with six sides(2).Usually you will not get
48、 a shock by touching the electric ray in one place only because_.（分数：35.50）A.the current in one place is not strong enough to give a shockB.the fish s electric cells are filled with jelly-like substanceC.to complete the circuit, you have to touch the fish in two placesD.a torpedo s electric cells contain more than one electric plates(3).The main idea of the third paragraph is that_.（分数：35.50）A.a mature torpedo is capable of producing enough electricity to knock down a manB.the
