　　Children are always boasting.They say things like“My Dad's car is bigger than your Dad's，”“My Mom is smarter than yours.”and“My family has more money than yours.”

　　The word“boasting” means __B___

　　A.骄傲 B.吹牛 C.顽皮 D.幼稚

　　Many plants and animals are going extinct.Mammoths，which are related(有关联的) with Asia elephants，are now extinct.There are no mammoths in the world today.

　　1.A mammoth is a kind of _C___.

　　A.plant B.bird C.animal D.tree

　　2.The word extinct means _C_

　　A.出现 B.危险 C.灭绝

　　Usually people make dumplings at home.If you have no time to make them，you can buy them from any supermarket. Then you take them home and eat them with vinegar.

　　The word“vinegar” means 醋

　　Water is made from oxygen and hydrogen.

　　The words“oxygen and hydrogen” mean 氢和氧

　　(二)根据上下文的意思来猜测

　　1.Some people like to walk quickly home after work，but I prefer to stroll home and look at the store windows along the way.(溜达)

　　2.She is usually prompt for all her classes，but today she arrives quite late.(准时的)

　　3.The door is so low that I hit my head on the lintel.(门梁)

　　(三)根据转折、因果关系猜测词义

　　通过因果关系猜词，首先是找出生词与上下文之间的逻辑关系，然后才能猜词。有时文章借助关联词(如because，as，since，for，so，thus，as a result，of course，therefore等等)表示前因后果。例如：

　　You shouldn't have blamed him for that，for it wasn't his fault.通过for引出的句子所表示的原因(那不是他的错)，可猜出blame的词义是“责备”。

　　(四)通过同义词和反义词的关系猜词

　　通过同义词猜词，一是要看由and或or连接的同义词词组，如happy and gay，即使我们不认识gay这个词，也可以知道它是愉快的意思;二是看在进一步解释的过程中使用的同义词，如Man has known something about the planets Venus，Mars，and Jupiter with the help of spaceships.此句中的Venus(金星)、Mars(

　　火星)、Jupiter(木星)均为生词，但只要知道planets就可猜出这几个词都属于“行星”这一义域。通过反义词猜词，一是看表转折关系的连词或副词，如but，while，however等;二是看与not搭配的或表示否定意义的词语，如：He is so homely，not at all as handsome as his brother.根据not at all...handsome我们不难推测出homely的意思，即不英俊、不漂亮的意思。
