D.标准状况HCl气体11.2VL物质量0.5molVL浓度0.5mol•L-1盐酸HCl物质量能计算其具体数值所计算通入氯化氢溶液物质量浓度
B、VL浓度0.5mol&#8226;L-1盐酸物质量0.5Vmol<img class="word-replace" src="/api/getdecpic?picenc=0admol&#8226;L-1盐酸0.1VL物质量Vmol再稀释至1.5VL所C=
0.5Vmol+Vmol
=1mol/L故B确．
A.加热浓缩盐酸导致盐酸挥发增强故C错误．
C.浓稀盐酸混合溶液体积直接加所混合溶液物质量浓度原2倍故D错误．
A、标准状况下的HCl气体11.2VL物质的量是0.5mol，VL浓度为0.5mol&#8226;L-1的盐酸中HCl的物质的量不能计算其具体的数值，所以无法计算通入氯化氢后溶液的物质的量浓度，故A错误．
B、VL浓度为0.5mol&#8226;L-1的盐酸的物质的量是0.5Vmol，10mol&#8226;L-1的盐酸0.1VL的物质的量是Vmol，再稀释至1.5VL，所以C=
0.5Vmol+Vmol
=1mol&#47;L，故B正确．
C、加热浓缩盐酸时，导致盐酸挥发增强，故C错误．
D、浓稀盐酸混合后，溶液的体积不是直接加和，所以混合后溶液的物质的量浓度不是原来的2倍，故D错误．
第二个选项颠倒了
仔细看应该能看懂

托福批改分类
大家最近批改了
Listen to a short conversation and then listen for a question about it.
Q: Describe the man’s problem and the two suggestions that his friend makes about how to handle it. What do you think the man should do, and why?
分类:第五题
话题:事件类
托福口语模拟题第五套第五题题干讲解：
In answering this question, you are supposed to listen to a short recording first. You answer needs to contain the description of the woman’s problem and her friend’s suggestions. In addition, you need to state your own opinion to close your answer.
观点提示：
From the listening material, we can learn that the man would like to visit his family but he doesn’t want to miss his economic classes. His friend gives him two suggestions. The first one is to borrow class note the second one is to ask the professor to attend the other section of the economic class before he visits his family. Then you can briefly state your opinion.
In this listening passage, the man has a problem in … His friend proposes two solutions for the man’s problem. One is …. And the other is…In my opinion, the first/second one is better. I think the man should … (solution you choose) … first because … He also indicates that … Finally …
would like to do sth 想要做某事；bring one’s grade up提高个人成绩；suggest sb do sth 建议某人做某事；be reluctant to do sth不情愿做某事；have problem doing sth做某件事有问题/困难；be not sure that 不确定某事；it’s hard to do sth做某事有困难
参考范文：
The man would like to visit his family over the weekend, but his friends are leaving before his economics class on Friday. He doesn’t want to miss the class because he needs to bring his grade up. His friend suggests that he borrow the notes from the class. His roommate didn’t have a problem lending him notes from that class earlier in the semester, but he’s reluctant to do that. The other possibility that his friend mentions is for him to attend another section of the same class on Thursday night, but he isn’t sure that the professor will give the same lecture. To find out, he would have to ask the professor. In my opinion, the man should stay for his economics class and take notes. It’s hard to read someone else’s notes, and besides, if he’s in the class, he can ask questions. If he wants to visit his family, he should try to find a ride on Saturday or on Friday after the class.
听力原文：
Friend: So what time should we pick you up on Friday? Can you be ready by noon or do you need another hour or so?
Student: I really wanted to spend the weekend with my family, and the ride with you would have made it even more fun, but . . .
Friend: You mean you aren’t going?
Student: I can’t. I’m not doing too well in my economics class, and I have a lecture Friday afternoon. I don’t think I should miss it.
Friend: Well, why don’t you borrow the notes from someone? Isn’t your roommate in that class?
Student: Yeah, he is. But I’ve already asked to borrow his notes once this semester. He didn’t seem to mind though.
Friend: Well, there you are. Unless you want to go to class on Thursday. I’m fairly sure that Dr. Collins teaches the same class Thursday night.
Student: Really? She probably wouldn’t mind if I sat in on the Thursday class, but I wonder if she’ll give the same lecture. You know, maybe they’re one week behind or one week ahead of us.
Friend: I suppose that’s possible, but it would be easy enough to find out. You could just tell her that you’d like to attend the Thursday session this week because you need to go out of town. Then you can ride home with us. If there’s a problem, you can still borrow your roommate’s notes on Sunday when we get back.
