An American researcher has developed a simple device to help people stop snoring (打鼾). The device restricts the movements of the tissue (器官组织) that causes the bad sound. Snoring is a common problem. It may prevent a person from getting enough sleep. It may also prevent enough oxygen from reaching the heart and lungs during the sleep. But for most people, snoring affects relations with another person who must sleep in the same room. Snoring happens when the sleeping person breathes with the mouth open. In the back of the mouth the tissues surrounding the entrance of the throat are soft. As the person breathes, the movement of the air around the soft tissues causes them to move or vibrate. This tissue movement causes the sound we call snoring. A number of possible solutions have been proposed. Some devices keep the mouth shut. They forced the patient to breathe only through the nose. A medical operation is also possible. Other devices listen for the sound of snoring and then wake the patient. The new anti-snoring device was developed by a dentist (牙医), George Wagner of the Indiana University School of Dentistry. He developed a piece of plastic that fits up against the inside of the mouth. The device keeps the soft tissues from vibrating and making the snoring noise. It was worn only at night. Doctor Wagner said several patients report that the simple device has ended their snoring problem. 1. The passage mentions all the bad effects on the snorer EXCEPTA. harming his friendshipB. his lack of enough sleepC. disturbing his roommateD. his lack of enough oxygen

If you've been on campus for very long, I'm certain that you've already heard about this course. You may know that last term about fifty percent of the students who selected my course failed it. Let me explain how this came about before you jump to any conclusions. In the first place, since this is a composition class, I expect my students to follow certain rules of formality (形式). Unfortunately, students today dislike having to follow rules of any kind, especially those which they may feel to be unnecessary. For example, I ask that each of your papers be typed. I count off points for various kinds of mistakes. A misspelled word will cost you 5 points. You'll lose 25 points if you misspell five words. If you write an incomplete sentence, you'll lose 10 points. If you give me two complete sentences as one without adequate punctuation (标点), you'll lose 15 points. I do not accept late papers. You will receive a zero for any theme (习作) which you fail to submit on time. I expect you to read each assignment. To make certain that you have read the assignment, I will give you a short unannounced quiz from time to time. This class meets on Mondays, Wednesdays, and Fridays. You will have a total of six major tests throughout the semester. Your final grade will be based on an average of these major tests and eight written themes. If you have any questions at any time, you can see me on Tuesdays. My office is on the second floor of this building. Your assignment for Wednesday is to read Hemingway's short story on Page 55. Friday will be the last class day of this week, so you can expect to write a short in-class theme for me then. 6. The course mentioned by the teacher is on___________A. readingB. assignmentsC. writingD. spelling
