下列各项比较中前者高于（或大于或强于）后者的是
A．CCl4和SiCl4的熔点
B．邻羟基苯甲醛（
）和对羟基苯甲醛（
）的沸点
C．SO2和CO2在水中的溶解度
D．H2SO3和H2SO4的酸性
答案：C
题目分析：A、CCl4和SiCl4都是由分子构成的物质，由于SiCl4的相对分子质量大于CCl4，分子间作用力也比CCl4大，所以广泛分子间作用力使物质熔化消耗的能量及高，因而其熔点也比CCl4高。错误。B、邻羟基苯甲醛（
）和对羟基苯甲醛（
）都属于分子晶体。由于在后者的分子之间还存在氢键，增加了分子之间的相互作用。所以后者的沸点高。错误。C、SO2在水中的溶解度为1:40；而CO2在水中的溶解度是1:1.因此前者大于后者。正确。D、H2SO3是弱酸，而H2SO4是强酸。所以酸性后者强。错误。
| Caesar was right. Thin people need watching. I’ve been watching them for most of my adult life, and I don’t like what I see. When these narrow fellows spring at me, I quiver to my toes. Thin people come in all personalities, most of them menacing. You’ve got your "together" in person, your mechanical thin person, your condescending thin purism, your tsk-tsk thin person, your efficiency-expert thin person. All of them are dangerous. In the first place, thin people aren’t fun. They don’t know how to goof off, at least in the best, fat sense of the word. They’ve always got to be adoing. Give them a coffee break, and they’ll jog around the block. Supple them with a quiet evening at home, and they’ll fix the screen door and lick S & H green stamps. They say things like "there aren’t enough hours in the day". Fat people never say that. Fat people think the day is too damn long already. Thin people make me tired. They’ve got speedy little metabolisms that cause them to bustle briskly. They’re forever rubbing their bony hands together and eyeing new problems to "tackle". I like to surround myself with sluggish, inert, easygoing fat people, the kind who believe that if you clean it up today, it’ll just get dirty again tomorrow. Some people say the business about the jolly fat person is a myth, that all of us chubbies are neurotic, sick, sad people. I disagree. Fat people may not be chortling all day long, but they’re a hell of a lot nicer than the wizened and shriveled. Thin people turn surly, mean, and hard at a young age because they never learn the value of a hot-fudge sundae for easing tension. Thin people don’t like gooey soft things because they themselves are neither gooey nor soft. They are crunchy and dull, like carrots. They go straight to the heart of the matter while fat people let things stay all blurry and hazy and vague, the way things actually are. Thin people want to face the truth. Fat people know there is no truth. One of my thin friends is always staring at complex, unsolvable problems and saying, "The key thing is fat people never say that." They know there isn’t any such thing as the key thing about anything. |

C．fat people who are inactive and easily get jaded but hates to be among those thin people who are active and energetic
D．thin people who get rid of things quickly but feels sick of those fat people who are all thumbs
