1正文 Article

Mars is often imagined as a flat, dusty desert, yet the surface of the planet is anything but featureless. In the enormous basin of Gale Crater, where NASA's Curiosity rover has been working since 2012, the landscape rises into ridges, buttes and cliffs whose shapes are unlike anything found on Earth. Among them stands a group of pale, sharply cut formations that have puzzled researchers for years, and which the rover is now slowly approaching.

These formations are the product of wind. On Mars, where the atmosphere is less than one percent as dense as Earth's, dust is lifted and driven across the surface at high speed. Carried particles act like sandpaper, grinding away the softer rock and leaving the harder layers standing proud. Over millions of years this patient process sculpts ridges that run parallel to the prevailing wind, giving the landscape a combed, almost architectural appearance.

What makes the site particularly interesting is not only its shape but its material. The cliffs appear to be built from layered deposits that may contain traces of ancient volcanic activity, either as ash that fell from the sky or as lava that once flowed across the crater floor. If that reading is correct, the rocks preserve a record of a time when Mars was still geologically active — a record that is rarely exposed so clearly.

Reading such a record is not straightforward. Each layer represents a period of deposition, and the boundaries between layers mark events: an eruption, a shift in wind direction, or a long pause during which very little happened at all. By examining how the layers are tilted, broken and cemented together, geologists can reconstruct a sequence of events and begin to estimate how long each stage lasted.

The difficulty is that the evidence must be gathered slowly. Curiosity travels at a walking pace and cannot be steered in real time; commands are sent, and the rover then carries them out on its own. Reaching the cliffs therefore takes years rather than weeks, and the most detailed measurements are expected only in 2027, when the rover will be close enough to drill into the rock and analyse its chemistry.

The value of the work lies beyond a single puzzle. Wind is a powerful force on any planet with an atmosphere, and comparing how it carves rock on Mars with how it does so in dry regions on Earth helps researchers understand landscapes that no one has ever visited. The same principles apply to the study of ancient climates, where the shape of a cliff can hint at how thick the air once was and how strongly the wind blew.

For the moment, the cliffs remain an unfinished sentence. What is already clear is that Mars is not a dead, static world but one that continues to change, if very slowly, under forces that can be observed and measured. The rover's slow approach is therefore less a journey than a form of reading, and the pages it is turning were written in dust and stone.

1. The cliffs on the horizon appear to be made of layers of ash. — 主语是复数 cliffs（on the horizon 只是修饰成分），谓语要用 appear，不能因为靠近 on the horizon 就写成单数 appears。
2. Since 2012, the rover has travelled slowly across the crater and has already drilled many holes. — Since + 过去时间点表示“从过去持续到现在”，主句必须用现在完成时 has travelled / has drilled，不能用一般过去时。

1. A — 第五段明确指出 Curiosity travels at a walking pace and cannot be steered in real time（以步行速度行进，且无法实时操控），所以要“years rather than weeks”，直到 2027 年才够近距离钻探。B、C、D 均无原文依据。
2. FALSE — 第三段说 cliffs appear to be built from layered deposits，第四段又说 Each layer represents a period of deposition，说明岩石是多层沉积、并非单一均匀的一层，故与原文矛盾。
3. grinding away — 第二段原句为 Carried particles act like sandpaper, grinding away the softer rock...，grinding away 意为“磨掉、磨损”，此处用现在分词作伴随状语，答案须与原文一致。
