   I had moved from my home in Zimbabwe to Botswana to work as a teacher for a year. When I saw my house there,I was surprised at how big and empty it was.①So I wondered how I would survive alone in such a big house.

   But I was not alone. One night,I was awakened by strange sounds. I turned on the lights and saw three skinks (石龙子) . I used a small stick to try to chase them out.

   Instead of leaving,they hid under the bed or in the space between the roof and walls. I gave up and decided to live with the skinks. They celebrated their victory in style. They ran around the house,making all sorts of noises. Sometimes they ran between my feet.

   But to me,the skinks were more than pets. I had realized they were harmless and even useful.

   One day,I saw three young skinks in a comer,gobbling up ants.②多亏了石龙子,我的卧室不再有 蚂蚁。Like most lizards,skinks need sunshine in the morning to warm up their bodies.

   The skinks became my alarm clock. Each morning,when I heard them squeezing under the door,I knew it was time to get up. But on cloudy days,they sometimes made me late for work.

   Since I had changed my attitude towards skinks,I was not so lonely. I often sat and watched them.

   At the end of the school year,I went back to Zimbabwe. Now I would miss my scary roommates. ③ I hoped that the next person who lived there would also learn to be patient and to let skinks be skinks.

   The shock of the recent earthquake in Pakistan has brought another shock : the rise of a small,mysterious island,coming out from the water.

   In the aftershock (余震) of the earthquake,people living in Gawadar,near the southwest coast,began to see a strange sight. They looked out into the Arabian Sea and saw a mountain-like shape coming out of the water. ‘‘ I could see this gray,dome-shaped (穹顶形状的) body in the distance,like a giant whale,” Bahram Baloch,a local journalist,told the BB   C. “Hundreds of people had gathered to watch it in surprise. ”

   When the earthquake happened,the force was so strong that it moved the sea floor,releasing gas. This gas pushed the seabed,mostly rock and sand,upward and out of the water. This is how mud volcanoes (火山) are formed. The island that measures about 20 meters high,30 meters long and 90 meters wide is actually the tip of the mud volcano.

   Is it safe? Although people have visited this new island,scientists have found dangerous gas coming from the newly formed island. “Our team found bubbles rising from the surface of the island,which caught fire when a match was lit,” said Mohammad Danish,a scientist,to Universe Today.

   These mud volcanoes are not rare. But it's striking because this one has popped up in a populated area,and not far out in the sea. However,it's not expected to last very long. Most of these mud volcanoes are swept back under the sea within one year.
