    [l] Scientists guess that 80% of a person's weight gain comes from genetics and 20% comes from the person's environment. By 1998, more than 130 genes and gene neighbors were found to have some link to weight gain or weight loss in people. These different genes can either work all together or work in groups. This means that different people may ___________________or lose weight with difficulty for different reasons.
    [2] One example of these different kinds of combinations is a family of genes that allows people to change extra fat into heat instead of storing the fat in the body. Animals which have this same family of genes do not gain weight easily as other animals. Other genes may affect how quickly the stomach lets the brain know that it is full. If these genes slow down the passage of this information, people may eat more than they really need. Genes are also thought to be linked with a person’s fidgets in a day. Fidgeting is small movements of a person's hands, feet, arms or legs usually when the person is nervous or excited. Fidgeting actually uses a lot of energy over a day and his energy usually comes from burning fat.
    [3] In one experiment about weight gain, researchers wanted to see how much energy different people used when they were resting. People in the experiment were asked to lie on a bed and not move for 40 minutes. Researchers then measured the energy the person used for breathing. They found that different people in the study used very different amounts of energy for this one job, breathing. Researchers calculated that some people in the study burned 1,067 calories per day while others burned up to 3,015 calories. Those people who burn fewer calories doing normal work or exercise have a slow metabolism(新陈代谢).

  • 缩写与简写

缩写与简写的概念:

用单词首尾字母组成一个新词的英语构词法叫做首尾字母缩略法。这种形式的英语构词生成的新词,读音主要有两种形式,即各字母分别读音;作为一个单词读音。
如:Foreign Language Teaching Agency→FLTA上海外教网
        Testing of English as a Foreign Language→TOEFL托福
        Teach English as a Foreign Language→TEFL
        Teach English as a Second Language→TESL
        Graduate Record Examination→GRE美国研究生入学考试


缩写的几种类型:

1、单词缩写应省略在辅音之后,元音之前:
英文单词缩写一般以辅音结尾,而不以元音结尾。如American省略为Am,而不省略为Ame或Amer,Medicine或Medical缩写为Med,European缩写为Eur等。但Science例外,缩写为Sci,可能是因为元音I之后又是元音E的缘故。缩写刊名每个词首字母必须大写,而不可全部都用大写或小写。
2、压缩字母法:
仅个别单词采用压缩字母方式缩写。
如:Japanese缩写为Jpn而不是Jan
        National应缩写为Natl而不是Nat
经常有读者将Japanese写成Jan是参考文献著录中常见的错误。
如:Japanese Journal of Ophthalmology,应缩写为JpnJOphthalmol,National Cancer Institute Research Report缩写为NatlCancerInstResRep。而Nat是Nature和Natural的缩写,如:NatureMedicine, Naturebiotechnology分别缩写为NatMed, NatBiotechnol。
另外CN是中国的国别代码,期刊缩写刊名中,ChinaChinese不得缩写为CN,而应缩写为Chin.采用压缩写法是为了避免与其他常用缩写混淆。
如:Japanese不能缩写为Jan,可能是Jan是January的固定缩写形式,National缩写为Natl而不缩写为Nat,可能是Nat是Nature和Natural的缩写。
3、学科名称缩写:
刊名中学科名称缩写很常见,因而了解学科名缩写规则非常必要。凡以-ogy结尾的单词,一律将词尾-ogy去掉,如Cardiology缩写为Cariol,Biology缩写为Biol,以-ics结尾的学科名词,缩写时将-ics或连同其前面若干字母略去。如:Physics缩写为Phys。以-try结尾的词,缩写时将-try连同前面若干字母略去。如:chemistry缩写为Chem。其中也包括其他形容词的缩写。
4、刊名中常用词和特殊单词的缩写:
期刊名中有些常用单词可以缩写为一个字母。
如:Journal缩写为J
        Quarterly缩写为Q
        Royal缩写为R
        New缩写为N
        South缩写为S
5、刊名首字母组合:
有些杂志名称缩写采用首字母组合,而且已被固定下来,一般都是国际上有较大影响的期刊,并得到国际上众多索引性检索工具的认同。
如:The Journal of American Medical Association缩写为JAMA, British Medical Journal缩写为BMJ等。
6、国家名称的缩写:
刊名中国家名称的缩写分为两种情况。如国家名称为单个词汇,缩写时常略去词尾或词的后部分若干字母。
如:American缩写为Am
        British缩写为Br
        Chinese缩写为Chin
而国家名称由多个词组组成时,常取每个词的首字母,如United States of America 缩写为USA或US。
7、虚词一律省略:
有许多虚词,如the, of, for, and, on, from, to等,在缩写时均省去。
如:Journal of chemistry缩写为J chem
       Archives of Medical Research缩写为Arch Med Res
