题目内容

【题目】下面文字阐述了人们在雾霾天气自我保护的具体做法,请简要概括成四点,要求每一点不超过7个字。

雾霾天气里,粉尘颗粒多,因而不主张早晚开窗通风,需要通风也要等到太阳出来再开窗。最好不出门,更不宜晨练,否则可能诱发呼吸道疾病,甚至导致心脏痛发作,引起生命危险。因为起雾时气压低,空气中的含氧量有所下降,人们很容易感到胸闷。早晨潮湿寒冷的雾气还会造成冷刺激,很容易导致血管痉挛、血压波动、心脏负荷加重等。如果需要外出,可以戴上口罩,这样可以有效防止粉尘颗粒进入体内。口罩以棉质口罩为好,因为一些人对无纺布过敏,而棉质口罩一般人都不过敏,而且易清洗。雾天的饮食宜选择清淡易消化且富含维生素的食物,多饮水,多吃新鲜蔬菜和水果,这样不仅可补充各种营养素和无机盐,还能起到润肺除燥、祛痰止咳、健脾补肾的作用。少吃刺激性食物,多吃些梨、枇杷、橙子、橘子等清肺化痰食品。

答:①__________________ __________________ __________________ __________________

【答案】①太阳出来再开窗 ②不适宜外出晨练 ③外出带棉质口罩 ④饮食应清淡健康

【解析】此题考查筛选文段的信息要点,要先切分层次,看看文段具体是从哪几个方面谈“保护措施”的,要注意排除不必要的信息,然后筛选出关键词。

【题目】They say there are three ways to experience the Grand Canyon; on foot, on mules(骡子) or by air. We chose the first. Up early; my husband and I and our three children couldnt wait to get started. We decided to walk along a lovely path named Bright Angel Trail.

As we set out, I was shocked at how narrow the path was. And I couldnt help noticing that the other tourists werent like us. They had heavy backpacks, water bottles, and hats. But as usual we were dressed, As the sun rose higher, Arizonas famous heat seemed to roast(烘烤) us. There was no shade and our legs were aching. We decided to go back, with the girl on my back and the boys far behind. By the time we finally got back, our legs were like jelly.

The next day, after wed had a long rest and a good breakfast, we were ready for another view of the Canyon by air. After our last walk, this would be the easiest thing in the world.

We called to each other excitedly as the plane took off and circled around the Canyon. But the smiles on our faces disappeared as the pilot tossed(翻转) the plane around, pretending he was going to hit the ground. I shouted, STOP, TAKE US BACK! When we finally arrived back on land, once again our legs were like jelly. We hardly spoke as we drove back.

As I said, there are three ways to view the Grand Canyon. We never tried the mules, but personally Id suggest a fourth: buy yourself a good magazine like National Geographic. That way, you can see the Canyon, without fear or tiredness.
