【简答题】SWOT实例分析 假设企业X有一个以WordPress为基础构件的网站，使用了分类标签，每两天至少添加一页内容，并且对行业有着深入的了解。它的域名不太理想——Businessnameandkeyword.com，不过也还差强人意。 企业X没有从搜索引擎中得到太多流量，但是其竞争对手企业Y做到了，这是因为企业Y网站存在的时间更长，在此期间获得了许多很好的链接。企业Y没有任何SEO计划，依赖首页带来所有的流量。这是因为企业Y有富含关键词的域名，人们已经在指向企业Y网站的链接上使用了这些关键词（为链接指定了富含关键词的锚文本），另一个原因是它在网络上有着悠久的历史。 目标搜索查询并不多；实际上，这一组核心关键词每个月的搜索量少于5万次。企业X的网站排名处于Google搜索结果的第2页，而企业Y排名第3，仅次于维基百科和About.com。 两家公司都没有在PPC（付费搜索）流量上投入资金，在这个市场上也没有给其他后来者留下太多的空间（竞争对手有10～15个）。从强度和数量来说，两个网站有着相似的链接权威性。这两家公司经营的产品主要依靠冲动性购买——他们的产品能够激发强烈的情绪。 请用SWOT法对企业X的SEO工作进行分析。SWOT表格.ppt

The utmost level of education is undoubtedly to have a university degree. However, not every university may meet your expectations. In order to state that you are a graduate of a good university, there should be some requirements to be met. In my opinion, a good university should have qualified teachers, technologically adequate buildings and many facilities for students. 2 First of all, it must have enough qualified teachers for each course. Qualified teachers should have adequate teaching skills in their subjects. Without adequate teaching skills, it will be difficult for the teacher to transfer his/her knowledge to the students. Also, as a person, the teacher should have proper personalities, that is, a teacher should be kind, supportive and understanding to his/her students. Otherwise, they may be disliked. So, good teachers are indispensable for a good university. 3 Secondly, a good university must have many buildings with adequate high technology facilities with students. The classrooms must be large enough and well–equipped. A small classroom or a classroom without technological supplies such as the internet or television will certainly demotivate students. In addition, libraries should have enough books and materials for students. This is very important to do research for students' studies or assignments. All these above considered, technologically developed buildings are necessary for a good university education. 4 Finally, a good university should have many facilities for students. For example, there must be enough sport centers and cafes for students to spend their time. Since students spend most of their time studying at school, they need a place to rest and chat with their friends. In addition, students sometimes need to get over their stress spending time in a sport center. Thus, beside academic study, a good university should provide social opportunities to its students. 5 In conclusion, universities are places where students spend the most important stage of their lives. Universities should support the learning process with qualified teachers, technologically adequate buildings and many social facilities. Students should become familiar with all these characteristics so that they can choose a good university, which will affect their future. EXERCISE 1.
