Why do plants grow in some places and not in others? Why does some land have so much growing on it, while other land has almost no plants growing on it at all?
To grow, plants need several things. One is warmth. In very cold places almost nothing grows. Plants also need water. In very dry parts of the earth only a few unusual plants can grow. That’s why dry deserts everywhere are almost not covered by trees or grass.
Plants must also have a place in which to put down their roots and grow. They find it difficult to grow on hard land. The town is built on hard land. The plants here have only the soil found between the cracks of the stones to grow in.
Another thing plants must have before they can grow is food.
What will happen if we try to make things grow on the sandy beach? A few plants, such as beach grass, will grow in sand, but most plants won’t. Even if the weather is warm enough and we water the plants each day, many of them will die because the sand on this beach has almost no food for plants.
【小題1】What things don’t most plants need to grow well according to the passage?
A．Warmth.              B．Food.                C．Sandy beach
【小題2】What does the underlined word “cracks” mean in the passage?
A．表面             B．縫隙                 C．夾層
【小題3】From the passage, we know that it is        for plants to grow in dry places.
A．difficult                B．impossible           C．important
【小題4】The reason why most plants can’t grow on the sandy beach is that       .
A．there isn’t enough sunlight
B．there is too much water
C．it has little food for plants
【小題5】The passage can most probably be found in a        book.
A．science              B．history              C．travel


【小題1】C
【小題2】B
【小題3】A
【小題4】C
【小題5】A

解析試題分析：這篇短文主要描述了指物的生長(zhǎng)環(huán)境的問(wèn)題，介紹了植物為什么不能在一些環(huán)境條件生長(zhǎng)的原因。
【小題1】根據(jù)短文最后一段描述可知大部分植物不能在沙灘上生長(zhǎng)，故選C。
【小題2】聯(lián)系下文of the stones to grow in.可知指的是石頭的縫隙，故選B。

【小題4】根據(jù)many of them will die because the sand on this beach has almost no food for plants.聯(lián)系上文可知選C。
【小題5】這篇短文主要描述了指物的生長(zhǎng)環(huán)境問(wèn)題，故最有可能在科學(xué)書(shū)籍中找到這類文章，故選A。
考點(diǎn)：關(guān)于植物生長(zhǎng)環(huán)境的說(shuō)明文
點(diǎn)評(píng)：本文中長(zhǎng)句較多，一時(shí)很難讀懂句子含義，注意多讀幾遍，不要強(qiáng)求非得理解一詞一句的含義，能把握文章大意就行。然后帶著問(wèn)題閱讀短文，一般就能順利找出答題依據(jù)。對(duì)于不能直接找到根據(jù)的問(wèn)題注意聯(lián)系上下文，根據(jù)短文中心總結(jié)出正確答案。
