(2013·高考湖北卷)Carbon dioxide，which makes a________between us and the sun，prevents heat from getting out of the atmosphere easily，so the earth is becoming warmer.| A．difference | B．comparison | | C．connection | D．barrier |
|
答案
| D |
解析
| 选D。句意：二氧化碳是我们和太阳之间的一道屏障，它使地球上的热量不容易释放出大气层，于是地球就变得越来越暖和。四个名词选项的主要含义：difference“分歧，区别”；comparison“比较”；connection“联系”；barrier“障碍，屏障”。语境说地球的热量因二氧化碳而不容易释放出大气层，因此这里选D，表示“障碍，屏障”。 |
