【解析】

本文介紹了沙子是一種常見的景觀。沙子也是一種有用的資源。沙是世界上僅次于水的第二大資源。然而,聯(lián)合國說,沙土并不是無限的,我們可能會用完的。沙子由非常小的巖石、土壤和礦物質(zhì)組成。它可能需要數(shù)萬年才能形成。我們每年用大約150億噸沙子建造房屋、道路和其他東西。開采沙可能會導(dǎo)致海灘消失,在靠近大海的地方會發(fā)生更多的洪水。此外,這可能會影響許多動植物的棲息地。

1句意:然而,聯(lián)合國說,沙子并不是無限的,我們有可能會用完它們。run out of“用完,用盡的意思。這里用it來指代上文的沙子(sand是不可數(shù)名詞)。故答案為:it。

2句意:沙子由非常小的巖石、土壤和礦物質(zhì)組成。根據(jù)rock, soil and minerals(礦物質(zhì))可知,這是幾種成分,因此piece用復(fù)數(shù)pieces。所以答案為:pieces。

3句意:但現(xiàn)在我們使用沙子的速度比它形成的速度要快。use“使用,動詞,因此后面用副詞來修飾。所以答案為:quickly。

4句意:據(jù)英國廣播公司報道,我們每年用大約150億噸沙子建造房屋、道路和其他東西。本題考查 use sth. to do sth. 用某物做某物。本題用動詞不定式做目的狀語。故答案為:to。

5句意:人們還把沙子放進海里,制造新的島嶼。由語境和音標[si:]提示可知,填:sea。這里是指用沙造島嶼。所以答案為:sea。

6句意:例如,棕櫚島由阿拉伯聯(lián)合酋長國迪拜的三個大型人工島嶼組成的。由語境和音標[lɑd]提示可知,填:large。three large man-made islands三個大型的人工島嶼。所以答案為:large。

7句意:2010年,他們用9400萬立方米的沙子建造。由In 2010可知,本題的時態(tài)為一般過去時。take的過去式為took。所以答案為:took。

8句意:如果人們繼續(xù)使用這么多沙子,它會在很多地方用完。本題考查keep doing sth. 繼續(xù)做某事。因此用動名詞做賓語。故答案為:using。

9句意:由于人們需要這么多沙子,他們正試圖開采更多的沙子。由語境和音標[lɑd]提示可知,填:since 自…以來; 因為; 由于。首字母要大寫。所以答案為:Since。

10句意:開采沙可能會導(dǎo)致海灘消失,在靠近大海的地方會發(fā)生更多的洪水。根據(jù)beaches to disappear and more floods to happen in places close to the sea海灘消失,在靠近大海的地方會發(fā)生更多的洪水。可知,這些是開采沙所導(dǎo)致的后果。因此填:cause。may是情態(tài)動詞,后跟動詞原形。故答案為:cause
