Moss is a common type of small plant. But it is one of the
oldest
(old) plants in the world. Unlike most plants we see, it has no flowers, no seeds, and no true roots(根). It usually grows in green clumps or soft mats and looks like a green carpet on the ground. Many people like moss
because/as
it always stays green and feels soft to touch.
Moss loves damp and shady places. You can
easily
(easy) find it on wet rocks, the surface of moist soil, old tree trunks, or even the walls of houses that don't get much sunlight. These cool and wet environments are perfect for its
growth
(grow).
Moss has some special features.
Instead
of true roots, it has tiny thread-like parts called rhizoids (假根).
The
rhizoids help it stick to surfaces and take in water. Its
leaves
(leaf) are very simple, often only one cell thick.
Moss plays an important role
in
nature. It helps keep soil moist by
holding
(hold) soil particles together. In this way, it prevents soil erosion. Besides, it provides a warm and safe home for small creatures like insects and tiny worms. There are about 12,000 kinds of moss around the world and each of them works silently
to protect
(protect) our environment.

答案

四、【语篇解读】本文是一篇说明文。文章主要介绍了苔藓的生长环境、结构特征及其在自然界中的重要作用。
1. oldest 句意:但它是世界上最古老的植物之一。“one of the+形容词最高级+可数名词复数形式”表示“最……的……之一”,此处应用形容词最高级。故填 oldest。
2. because/as 句意:许多人喜欢苔藓,因为它总是保持绿色且触感柔软。上下文是因果关系,前果后因。故填 because/as。
3. easily 句意:你很容易就能在潮湿的岩石、湿润的土壤表层、老树干,甚至是光照不足的房屋墙壁上找到它。修饰动词“find”,应用副词。故填 easily。
4. growth 句意:这些凉爽且潮湿的环境非常适合它的生长。根据“its”可知此处应用名词。故填 growth。
5. Instead 句意:它没有真正的根,而是有细小的线状部分,称为假根。根据上文“it has no flowers, no seeds, and no true roots”可知苔藓没有真正的根,只有假根,instead of 表示“而不是;代替”;句首首字母需大写。故填 Instead。
6. The 句意:这些假根帮助它附着在表面并吸收水分。此处特指上文提到的“假根”,应用定冠词;句首首字母需大写。故填 The。
7. leaves 句意:它的叶子非常简单,通常只有一层细胞厚。根据“are”可知此处应用名词的复数形式。故填 leaves。
8. in 句意:苔藓在自然界中发挥重要作用。play a role in ... 表示“在……中发挥作用”。故填 in。
9. holding 句意:它通过将土壤颗粒粘在一起,帮助保持土壤湿润。介词“by”后接动名词形式。故填 holding。
10. to protect 句意:世界上大约有 12000 种苔藓,每一种都在默默工作以保护我们的环境。分析句子可知,句中已有谓语动词“works”,此处应用动词不定式作目的状语。故填 to protect。
