综合运用同义词和利用反义词提升做英语猜词题技巧
(1) 利用同义词。
一是要看由and 或or连接的同义词词组。如:happy or gay，即使不认识gay这个词，也可以它是“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，但只知道planets就可猜出这几个词都属于“行星”这一义域。

(2) 利用反义词。
一是要看表示转折关系的连词或副词，如but, however等。二是与not搭配的或表示否定意义的词语。如：Tom is lazy but his brother is industrious.该句中but表示转折，就暗示了lazy和industrious是一对反义词，由此可知industrious意为“刻苦的、勤奋的”。

As we know, all living things have to eat food. For a man, a tiger, a fish, a bird, or even a worm, food is necessary. Generally speaking, all living things are sure to die without food. In every part of the world, many different kinds of animals share living places and live in communities (群落) together. They are connected in a food chain (链).
Within a food chain, some living things are producers and some are consumers (消费者). Plants are producers because they use sunlight, soil and other things to make their own food. Animals are consumers because they have to eat other animals or plants.
There are four different kinds of consumers in the animal kingdom. A carnivore is an animal that only eats other animals. An herbivore is an animal that only eats plants. An omnivore is an animal that eats both plants and animals. A scavenger is an animal that eats dead animals. 
Look at the picture. It is an example of a food chain. The food chain shows the order that animals eat each other in a community. In the picture, you can see what animal or plant is food for another animal. See? A leaf is food for a grasshopper, which then becomes food for a hungry mouse. The mouse is food for a snake. The snake is eaten by an eagle. In this way, all of these animals are connected.
根据上文内容判断正 ( T ) 误( F )
