介词(The Preposition)又叫做前置词,通常置于名词之前。它是一种虚词,不需要重读,在句中不单独作任何句子成分,只表示其后的名词或相当于名词的词语与其他句子成分的关系。中国学生在使用英语进行书面或口头表达时,往往会出现遗漏介词或误用介词的错误,因此各类考试语法的结构部分均有这方面的测试内容。 1. 介词的种类 英语中最常用的介词,按照不同的分类标准可分为以下几类: (1). 简单介词、复合介词和短语介词 ①.简单介词是指单一介词。如: at , in ,of ,by , about , for, from , except , since, near, with 等。②. 复合介词是指由两个简单介词组成的介词。如: Inside, outside , onto, into , throughout, without , as to as for , unpon, except for 等。 ③. 短语介词是指由短语构成的介词。如: In front of , by means o f, on behalf of, in spite of , by way of , in favor of , in regard to 等。 (2). 按词义分类 {1} 表地点(包括动向)的介词。如: About ,above, across, after, along , among, around , at, before, behind, below, beneath, beside, between , beyond ,by, down, from, in, into , near, off, on, over, through, throught, to, towards,, under, up, unpon, with, within , without 等。 {2} 表时间的介词。如: About, after, around , as , at, before , behind , between , by, during, for, from, in, into, of, on, over, past, since, through, throughout, till(until) , to, towards , within 等。 {3} 表除去的介词。如: beside , but, except等。 {4} 表比较的介词。如: As, like, above, over等。 {5} 表反对的介词。如: againt ,with 等。 {6} 表原因、目的的介词。如: for, with, from 等。 {7} 表结果的介词。如: to, with , without 等。 {8} 表手段、方式的介词。如: by, in ,with 等。 {9} 表所属的介词。如: of , with 等。 {10} 表条件的介词。如:

2016年职称英语综合类新增文章

2016年职称英语教材综合类新增文章 第二篇Common Questions about Dreams Does everyone dream? Yes. Research shows that we all dream. We have our most vivid dreams during a type of sleep called Rapid Eye Movement (REM) sleep. During REM sleep, the brain is very active. The eyes move quickly back and forth1 under the lids, and the large muscles of the body are relaxed. REM sleep occurs every 90-100 minutes, three to four times a night, and it lasts longer as the night goes on. ___1___ We dream at other times during the night, too, but those dreams are less vivid. Do people remember their dreams? A few people remember their dreams. However, most people forget nearly everything that happened during the night — dreams, thoughts, and the short periods of time when they were awake. ___2___ It seems that the memory of the dream is not totally lost, but for some reason it is very hard to bring it back2. If you want to remember your dream,the best thing to do is to write it down as soon as you wake up. Are dreams in color? Most dreams are in color. However, people may not be aware of it for two reasons :They don’t usually remember the details of their dreams, or they don’t notice the color because it is such a natural part of our lives. ___3___ Do dreams have meaning? Scientists continue to debate this issue.3 ___4___ Some people use dreams to help them learn more about their feelings, thoughts, behavior, motives, and values. Others find that dreams can help them solve problems. It’s also true that artists, writers, and scientists often ge t creative ideas from dreams. How can I learn to understand my dreams? The most important thing to remember is that your dreams are personal. The people, actions, and situations in your dreams reflect your experience, your thoughts, and your feelings. Some dream experts believe that there are certain types of dreams that many people have,even if they come from different cultures or time periods. Usually, however, the same dream will have different meanings for different people. For example, an elephant in a dream may mean one thing to a zookeeper and something very different to a child whose favorite toy is a stuffed elephant. ___5___ Then look for links between your dreams and what is happening in your daily life. If you think hard and you are patient, perhaps the meaning of your dreams will become clearer to you. 词汇: vivid /'vivid/ adj. 清晰的,生动的,逼真的 lid /lid/ n. 眼睑(=eyelid) motive /m?utiv/ n. 动机 stuffed /st?ft/ adj. 填充的,塞满了的 注释: 1. back and forth:来回地,反复地。

Ebola is a dangerous and often lethal viral infection. Scientists believe that humans contracted the virus by eating the meat of rare animals. It is now believed that bats are the primary carries of the virus. 2 To date, there are only three major countries in West Africa experiencing a major outbreak: Sierra Leone, Liberia and Guinea. However, other countries such as Nigeria have reported confirmed cases of Ebola within their borders. 3 Unless you recently visited one of the three affected West countries you risk of contracting the virus is virtually zero. Unlike other recent airborne virus outbreaks like SARS, the Ebola virus can only be spread through direct contact with an infected person. Specifically, Ebola is spread through contact with body fluids. Though, the virus is transmittable, only an infected person exhibiting symptoms is communicable. 4 The signs and symptoms of Ebola are non-specific and patients typically exhibit them after a week of contracting the virus. Symptoms may appear as early as two days or as late as three weeks after initial infection. Symptoms include disgust, weakness and stomach pain. More uncommon symptoms include chest pain, bleeding and sore throat. 5 Ebola is devastating because of its ability to attack and replicate in every organ of the body. This causes an overstimulation of the body’s inflammatory response, causing the flu-like symptoms. The virus also causes bleeding and impairs the body's normal clotting mechanism (凝血机制), making bleeding even more severe. Loss of blood volume and decreased organ perfusion (器官灌注)ultimately lead to organ failure and death. 6 The current outbreak is the deadliest viral outbreak in over 35 years.
