本文介绍了沙子是一种常见的景观。沙子也是一种有用的资源。沙是世界上仅次于水的第二大资源。然而,联合国说,沙土并不是无限的,我们可能会用完的。沙子由非常小的岩石、土壤和矿物质组成。它可能需要数万年才能形成。我们每年用大约150亿吨沙子建造房屋、道路和其他东西。开采沙可能会导致海滩消失,在靠近大海的地方会发生更多的洪水。此外,这可能会影响许多动植物的栖息地。
【1】句意:然而,联合国说,沙子并不是无限的,我们有可能会用完它们。run out of“用完,用尽”的意思。这里用it来指代上文的沙子(sand是不可数名词)。故答案为:it。
【2】句意:沙子由非常小的岩石、土壤和矿物质组成。根据rock, soil and minerals(矿物质)可知,这是几种成分,因此piece用复数pieces。所以答案为:pieces。
【3】句意:但现在我们使用沙子的速度比它形成的速度要快。use“使用”,动词,因此后面用副词来修饰。所以答案为:quickly。
【4】句意:据英国广播公司报道,我们每年用大约150亿吨沙子建造房屋、道路和其他东西。本题考查 use sth. to do sth. 用某物做某物。本题用动词不定式做目的状语。故答案为:to。
【5】句意:人们还把沙子放进海里,制造新的岛屿。由语境和音标[si:]提示可知,填:sea。这里是指用沙造岛屿。所以答案为:sea。
【6】句意:例如,棕榈岛由阿拉伯联合酋长国迪拜的三个大型人工岛屿组成的。由语境和音标[lɑd]提示可知,填:large。three large man-made islands三个大型的人工岛屿。所以答案为:large。
【7】句意:2010年,他们用9400万立方米的沙子建造。由In 2010可知,本题的时态为一般过去时。take的过去式为took。所以答案为:took。
【8】句意:如果人们继续使用这么多沙子,它会在很多地方用完。本题考查keep doing sth. 继续做某事。因此用动名词做宾语。故答案为:using。
【9】句意:由于人们需要这么多沙子,他们正试图开采更多的沙子。由语境和音标[lɑd]提示可知,填:since 自…以来; 因为; 由于。首字母要大写。所以答案为:Since。
【10】句意:开采沙可能会导致海滩消失,在靠近大海的地方会发生更多的洪水。根据beaches to disappear and more floods to happen in places close to the sea海滩消失,在靠近大海的地方会发生更多的洪水。可知,这些是开采沙所导致的后果。因此填:cause。may是情态动词,后跟动词原形。故答案为:cause。
