塔克拉玛干沙漠“锁边”工程完成“合龙”。学生会搜集了相关资料用来制作展板。

The Taklimakan Desert(塔克拉玛干沙漠) is the largest desert in China. It lies in Xinjiang. It’s really huge, about 337,000 square kilometres(平方千米). The sand here is light and soft. When strong winds blow, the sand flies and the desert moves. The desert can cover roads, farms, and even people’s homes.
But now we are working hard to stop it. In 2024, China finished a 3,046-kilometre green belt(绿化带) around the Taklimakan Desert.
How do we stop the sand?
▶ Sand barriers(沙障)
We use straw(稻草) and wire(金属丝) to build 1-metre-tall walls that slow down the wind.
▶ Deep roots
Trees and flowers grow roots deep into the ground. The roots hold the sand harder.
▶ Solar power(太阳能)
We turn solar energy into electricity(电). Then machines can take the underground water to water plants.
▶ Straw squares
We stick straw into the sand to make big squares. These squares help keep the sand in place. Trees and flower seeds can grow safely inside.

These squares help keep the sand in place.
这些方格有助于固定流沙。

任务一:
1. C 【细节理解】由材料中的“The Taklimakan Desert...It's really huge, about 337,000 square kilometres.”可知,塔克拉玛干沙漠的面积是 337 000 平方千米。
2. A 【细节理解】由材料中的“When strong winds blow, the sand flies and the desert moves. The desert can cover roads, farms, and even people's homes.”“But now we are working hard to stop it.”可知,当强风吹起时,沙子飞舞,沙漠也随之移动;沙漠会覆盖道路、农田,甚至人们的家园;修建绿化带是为了固沙。
3. B 【词义猜测】由画线词的上文“We use straw and wire to build 1-metre-tall walls...”可知,此处“that”指代的是这些1米高的墙。
任务二:
4. wind 【细节理解】由 Sand barriers 部分中的“...1-metre-tall walls that slow down the wind.”可知,沙障的作用是削弱风力。
5. water 【细节理解】由 Solar power 部分中的“Then machines can take the underground water to water plants.”可知,太阳能产生的电可以帮助机器用地下水灌溉植物。
6. sand 【细节理解】由 Straw squares 部分中的“These squares help keep the sand in place.”可知,草方格的作用是防止沙子移动。
