person.Do they put you down?Do they annoy you?Assess clearly why you no longer want this person in your life and be firm in your decision.If you are dumping a friend because they are unreliable,the easiest solution is to graduallycut them out of your life.If he or she never makes time for you then they probably won't noticethat you are not making time for them either.People who don't value your time do not value you;leave them out of your life.If you have decided that you want to dump a friend because you don'twant to share their lifestyle,then you need to make yourself very clear.You need to set clearboundaries.And if the person has committed some unforgivable mistakes,you also need to speakup.You need to clearly explain that whatever they did was unacceptable and you cannot pretendthat it did not happen.You need to tell them that this was not OK and the friendships can no longermove on.It might be tempting to give someone the silent treatment,but remember that everything thatseems self-evident to you is not always equally obvious to others.The other person might not evenknow that they hurt your feelings!If someone's behavior is really bothering you and they are morethan a casual acquaintance,you should carefully but surely speak up.Listening for specific comprehension1.What is the easiest solution when you want to dump a friend who is unreliable?2.What does

Little privacy2. Increased social life 2. Limited space3. Possible low GPA (grade point average)■ScriptThere are pros and cons of living on campusPros1. Accessibility to the school. If you live on campus, you can easily walk to the classes, libraries, computer labs, cafeterias, etc. You don’t have to waste time and money on driving to school, finding a parking space, and so forth.2. Increased social life. Living on campus will allow you to meet more people and establish more friendships than living off campus. You will also usually be aware of any campus activities and how to be involved in them.Cons1. Little privacy. When living in a dorm, it can be very hard to find privacy. You have to share bedrooms, bathrooms, etc. You may never have quiet time in your dorm because there will always be something going on.2. Limited space. At most colleges, the dorm rooms are tiny. You have to limit what you bring to school, or your space will betoo crowded.3. Possible low GPA (grade point average). Because dorm life is very social, your grades may be affected in a negative way. If you constantly choose hanging out with your dorm buddies over studying at the library, then your GPA will suffer.Ⅱ.

Math, social studies, science and all other regular courses are taught in both languages. And they learn about the culture of the other country.Milady Baez is Deputy Chancellor of English Language Learners and Student Support. She says these dual-language programs will help children succeed in the future.“The jobs of the future req uire that our students know more than one language.

It is the largest private university to drop the test requirement.Karen Stroud Felton is the Dean of Admissions at George Washington University.

The Institute of International Education and the State Department made the report.The study also demonstrates trends over the past 15 years.

You hear of this horror tale before even stepping foot on a college campus. So what exactly is the freshmen 15? Legend says that during your freshmen year of college, you end up gaining around fifteen pounds. Is this simply a story told to scare young freshmen, or a reality?The bad news is that a noticeable weight gain does occur among college students. However, the good news is it’s not as drastic as fifteen pounds. Food served in the dining halls is ladenwith fats while exercise in college has become a true burden. It is difficult to schedule a workout session among the already busy schedule filled with classes, clubs, homework, and organizations. Here at USC, the professors like to pack their students with work upon work, so students can truly “eat the fruits of the knowledge tree.” For an average student, it is considered a celebration if you could simply finish all your homework on time and sleep before 2 a.m. With that said, who cares about exercise?Listening for specific comprehension1. According to the passage, what does “15” refer to?2. How is the food like in the college’s dining halls?3.

C■ScriptListening for general comprehensionIt’s necessary for a student to take notes when he attendsa lecture. The notes can be readily used in the future when the student forgets or reviews something.When a student takes notes in a lecture he has to do four things.Firstly, he has to understand what’s said, as the speaker says it. He can’t stop the lecture in order to look up a new word or check an unfamiliar sentence pattern.The second thing the student has to do is to d ecide what’s important in the lec ture. Many lecturers pause, and speak more slowly and loudly, when they’re making an important point.The third task that faces the student is that he has to write down the important points. The student should abbreviate, write down the important words, usually nouns, sometimes verbs or adjectives, and should write one point on each line. He ought, if possible, to choose a moment to write when the lecturer isn’t giving vital information.Finally, the student’s notes must sh ow the connections between the various points he’s noted. If he makes intelligent use of spacing and underlining, together with the use of conventional signs and the numbering of points, he’ll be able to understand the framework of the lecture more easily. Listening for specific comprehension1. Why is it necessary for a student to take notes?2. What can a student do during a lecture if there is something he can’t understand?3.
