(10 points)Signs can sometimes be seen at the entrance of a house, expressing that a tramp（流浪汉） has passed. This special sign-language is frequently 1 by tramps to inform their 2 whether the host of a certain house is friendly or unfriendly, and to 3 them the trouble of making unnecessary calls.Quite 4 one day, I came across a real tramp. He was such a rare sight these days that I stood some distance away and watched him. He was dressed just as a tramp should be 5 , old worn trousers, and a jacket many sizes too big for him. On his head there was a battered old hat and his boots were so old and worn; they were almost coming into 6 But the man himself looked cheerful as if he had not been a 7 , for the tramps face lit up with 8 He entered the front gate confidently and rang the bell. When the door opened, I saw him 9 his hat but couldnt hear his words. The 10 was very short indeed, for no sooner had he spoken a few words than the door closed fiercely in his face. I felt 11 for him as he walked 12 out of the house, But just as quickly, his face lit up again and he moved quickly towards the gate. There he stopped, looked at the sign, and 13 his head seriously as if he had made a bad mistake. 14 deeply into his pockets, he produced a piece of chalk, rubbed out the 15 sign and made a new one in its place. He stared at it for a moment smiling to himself, then gathered his 16 , pushed back his hat and began walking towards the next house at an unhurried 17 , whistling as he went along.1、AemployedBmadeCtakenDput up2、AparentsBclassmatesCfellowsDfriends3、AshareBsaveCgiveDput4、Ain a wayBby mistakeCby the wayDby chance5、AwithBinCbyDon6、Aa fashionBa designCpiecesDblocks7、AsuccessBcareCfailureDfamily8、AgaveBgotCsetDmade9、AdrawingBkissingCcorrectingDstudying10、ApleasedBstrangeCfunnyDexciting11、AsurpriseBsatisfactionCworryDdisappointment12、AriseBput onCraiseDthrow13、AconversationBintroductionCquarrelDgreeting14、AhappyBfrightenedCworriedDsorry15、AcheerfulBsadlyCbravelyDeagerly16、AwavedBswungCshookDnodded17、ADiggingBStealingCPuttingDLooking18、AappearingBmovingCshiningDexisting19、AbelongingsBclothesCumbrellaDstick20、AstepBpositionCpaceDsituationSection II Reading ComprehensionPart ADirections:Read the following four texts.

So the nice slow down and they move less. And when the researchers restored the activity of that dopamine receptorDR2the mice started moving more, even though they were still obese. The team also saw that lean mice missing the DR2 receptor acted like obese mice. This is the target, says Kravitzrestoring that dopamine receptor function. “Maybe 20 or 30 years down the road, we could do that in people,” he says.And there is one more thing: The scientists fed normal mice and the mice lacking DR2 the same high-fat diet. Both sets of mice gained weight at the same rate.Kravitz says this is important because mice lacking DR2 move less from the get-go, whereas a normal mouse takes a little time to start seeing that dopamine receptor-related loss of exercise. The ability to exercise seems to be disconnected from weight gain, he says.“Exercise is a healthy thing to do, but its impact on weight loss has been exaggerated,” he says. “We have to be realistic about the size of the effect of exercise on weight, as opposed to health benefits.”Still, before you abandon your New Years exercise plan, keep in mind that this study was done using a high-fat diet, and not the normal calorie restriction that people maintain when they diet.Thats a big drawback to the work, says Vicki Vieira-Potter, a University of Missouri physiologist not involved in the study.“They feed the mice with high-fat diet, it damages the receptor, and that decreases activity. Those who plan to lost weight should r
