四、短文填空
When you think of the hottest place on Earth, you might say the deserts in the Middle East. I1 fact, there is only one place that can hold such a title（头衔）—Dallol, in the northeast of Ethiopia. The temperature（温度） during the day can r2 quickly to $50°\mathrm{C}$.
The Red Sea once c3 Dallol. But under the hot sun, all water evaporated(蒸发). The only thing left is salt. It seldom rains in Dallol, and there stands two volcanoes（火山）. Dallol's hot weather m4 that few things can grow here. There are no s5, no stores and no roads. You can o6 ride camels（骆驼）, with the nearest village a three-day trip away.
V7 Dallol is still not safe and few travellers have made it. Visitors must be c8 when walking around hot areas because the salt surface is easy to break（裂）. I9 a person were to step on it, he could fall into（掉入） the $100°\mathrm{C}$ water. Getting help is difficult because the nearest hospital is several h10 away. So if you plan a trip to the hottest place on Earth, make sure you walk carefully and bring enough water.
