Question

A desert is a beautiful land of silence and space. The sun shines, the wind blows, and time and space seem endless. Nothing is soft. The sand and rocks are hard, and many of the plants even have hard needles instead of leaves.

The size and location of the world's deserts are always changing. Over millions of years, as climates change and mountains rise, new dry and wet areas develop. But within the last 100 years, deserts have been growing at a frightening speed. This is partly because of natural changes, but the greatest makers are humans.

Humans can make deserts, but humans can also prevent their growth. Mauritania is planting a similar wall around Nouakchott, the capital. Iran puts a thin covering of oil on sandy areas and plants trees. The oil keeps the water and small trees in the land, and men on motorcycles keep the sheep and goats away. The USSR and India are building long canals to bring water to desert areas.

1.In this passage, the underlined word “needles” refers to ________.

A．small, thin pieces of steel

2.Which of the following is NOT true?

A．The greatest desert makers are human beings.

B．There aren't any living things in the deserts.

D．The size of the deserts is always growing.

3.People in some countries are fighting a battle against ________.
