第14题：
What are the advantages and disadvantages of grammar-translation method?
The main advantages of this method are: first, comparison between two languages helps students to have a better understanding of the meaning of abstract words and complicated sentences. Second, systematic study of grammatical rules plays an important role in fostering students' ability of reading comprehension and producing grammatically correct sentences. Understanding and manipulating the morphology and syntax will develop students' ability of analyzing and solving problems. Third, the focus on understanding literary texts provides the situation in which reading and writing abilities are well trained. Fourth, it makes few demands on teachers although it often creates frustration for students. It is relatively easy to apply.
Disadvantages in this method are: First, overemphasis on translation can never emancipate the learners from dependence on the first language. Second, knowing a large number of grammatical rules cannot ensure that students can use them appropriately in real communicative situation. Third, it puts too much emphasis on reading and writing and neglects listening and speaking. Fourth, the texts are mostly taken from literary works. The language learned often doesn't meet the practical needs of the learners. Fifth, memorizing grammar rules and bilingual word lists does not motivate students to actively communicate in the target language.

问答题Topic 2：My View on College Students’ Use of Mobile Phones Questions for reference: 1) What is the phenomenon of college students’ using mobile phones? 2) What might be the advantages and disadvantages of their using mobile phones? 3) What could be done to this problem?正确答案： 【参考答案】
My name is... My registration number is... My topic is: My View on College Students’ Use of Mobile Phones.
China is becoming a country with the biggest population of mobile phone subscribers and an increasing number of college students are joining the existing users. Statistics show that eight out of ten college students have got one. However, is it necessary for a college student to own a mobile phone?
In my opinion, there is nothing wrong for a college student to have a cell phone, with is, students will be better connected with friends and parents. What’s more, mobile phones play an important role in graduates’ job-hunting. Therefore, instead of banning the use of mobile phones, schools should take measures to guide an appropriate use of them on campus, For example, students are required to switch off their phones in classrooms and under no circumstances should they use a mobile phone during exams. In some public places, like libraries, a poster can be placed at the entrance to alert library users to switch their phones to vibration mode before they enter the library.
I believe mobile phones can bring benefits to our students as long as we can make good use of them. 解析： 暂无解析 -
