Food chains are just used to show who eats what in a very simple way. 21 Food Chains Here are some examples of food chains. ●A garden food chain might look like this: 22 ●Humans can also be part of a food chain. A farm food chain could look like this: 23 A food chain shows how plants and animals are connected with each other based on the foods they eat. Food chains are different depending on the habitat. A habitat is the scientific name for a place where animals and plants live. Habitats can be very different from each other, so a garden food chain would be very different from a farm food chain. 24 Food chains usually start with a green plant, such as grass or a tree. This is because plants can directly change sunlight into energy that they can use for themselves. These plants are called “producers”, and they create or produce their own food. They use this food to grow leaves, flowers, fruit and seeds. 25 Food Chain Disruption（中断） When the balance（平衡） of a food chain is broken, it may result in a bad situation. An example is overfishing. Over the years, humans have been catching too many fish at a quick speed, leaving not enough to keep a healthy population. Because of this, other animals, such as turtles, are endangered. So, humans should make sure our activities don’t harm the ecosystem. 26 1.写作方式题The writer explains “food chains” by ________.( ) D A. telling stories B. asking questions C. listing numbers D. giving examples 【解析】写作方式题。根据“Here are some examples of food chains.”可知，作者通过举例子的方式来介绍食物链。 27 2.单词还原题What can be best put in “▲” in the second food chain?( ) A A. chickens B. trees C. sunlight D. flowers 【解析】单词还原题。根据“A food chain…based on the foods they eat.”以及常识可知，虫子吃叶子，鸡吃虫子，人类吃鸡， 因此第二条食物链处填chickens更合适。 28 3.What can we know from the passage?( ) B A. Food chains usually start with human beings. B. Different habitats lead to different food chains. C. A garden food chain may be the same as a forest food chain. D. Plants are called “producers” because they produce food for others. 29 【解析】推理判断题。根据“...so a garden food chain would be very different from a farm food chain”可知，因为生活环 境不同，所以花园的食物链和农场的食物链不同，由此可推知不 同的生活环境造就了不同的食物链。 30 4.The writer mainly wants to ________ in the last paragraph.( ) C A. stop people from catching fish B. show us what food chain disruption is C. ask people to keep the balance of the ecosystem D. tell us how many endangered animals there are 【解析】写作目的题。根据“So, humans should make sure our activities don’t harm the ecosystem.”可知，作者在最后一段想 要呼吁人们保持生态系统的平衡。 31 【主旨大意】本文是一篇说明文。文章主要介绍了食物链的原理 并呼吁人类要保护生态平衡。 32 Ⅲ.短文填空 文体：说明文 词数：约260词 难度：★★★☆☆ 建议用时：8 mins pollute they expect hungry work government human lead appear big 33 About 1,101 manatees died in Florida last year, which was a record.
