Take for (1) the student who is away from home at college or university: if he tends to wrap himself up more than the others, this is because he is probably feeling (2). (Psychology of Clothes)On a busy day you’ve got to dash from job to (3), it’s all very hectic, but basically you’ve always got to have everything literally by the phone, be ready to leave at a moment’s notice. But there’s variety in it. Making TV (4) has in fact now overtaken straightforward fashion as our favourite occupation. It’s more fun than photographic work, where one split second decides whether you look nice or not. In a TV commercial there’s some acting involved, and you have to keep it up for a while, which is more of a challenge. (Fashion Model)Dress is very important and you should (5) turn up in jeans and an old sweater if you’re after a job in an office or a place of work where you will be meeting people, dealing with clients and that sort of thing. Clean, smart clothes are the order of the day, and try to avoid stage (6), like some nervous actor on the opening night of a new play. (Interviews)Four men have been shot in the head in the last three weeks. The men were all transients and (7) alone at the time of the killings. Please tell everyone in this chapel and those along the streets to come indoors at night to any of the missions or shelters. When they are full please tell the men to group together, not to be (8) at night, but huddle for safety. The lives of the men may depend upon their following these instructions. (A New Victim in LA of a Killer of the Homeless)Creative people like architects or fashion designers do a great deal of aimless doodling, whereas writers, on the other (9), do very little because they have a way of expressing themselves in words. I think probably (10) with disabilities are the best doodlers, because their normal outlets are blocked. (Graphology)“How do you know for sure that those 35 women have indeed not smoked at all? Maybe they’re misleading you.” “It’s all an (11) system. Each time they come for an examination they reaffirm their refusal to smoke. And certainly we trust those patients and feel that they (12) following it. Other patients, of course, have stated they have started smoking again. So I think it’s a pretty good cross section.” (Smoking Harms Baby During Pregnancy)We would like to have the sheriff go to them and say, “Pack (13)! Clear up! Get out of the state by sundown!” But we cannot. It is not against the law to believe in evil. The white supremacists are protected by (14) that are meant to protect everybody. That’s everybody. And we have to keep those laws. We can only watch these creeps and be ready when they make their move. (Neo-Nazi)So I went into the Barbazon Plaza Hotel to warm myself, because all the buildings in New York are centrally heated, and as soon as I’d got into the hotel, I noticed that the foyer was covered with (15) and, in one corner of the foyer, I saw this old woman. She had a Persian lamb hat on her head, but affixed to this Persian lamb hat was the same long crook-like (16)! (A Coincidence in New York)Critics of the system in Mexico say it is not truly democratic (17) the opposition parties had virtually no chance of taking power. But those parties have grown stronger in recent years and there is increasing pressure to change the procedures for elections. Today the Mexican Congress began work on a package of reforms that eventually could give opposition parties a greater voice in politics in (18). (Election in Mexico)So I went down to the police station and said that the money’d been stolen and would the police please come to the house, and investigate. And would they also investigate my (19), whom I suspected. And they said, well, they wouldn’t come and search the cook or look round the house unless I made a definite accusation against him. And if I made a definite accusation against him, they’d come along and take him back to the (20) station and really sort it out. (The Unfortunate Story of the Lost Money)
