第三部分：阅读理解（共20小题；每小题2分，满分40分）

阅读下列短文，从每篇短文后所给各题的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。

Centuries ago, many houses in a bad state in London were torn down to make way for new streets．However, the construction project was put off for quite some time, and the foundations of the houses pulled down were left in the open.

One day, a team of scientists arrived, only to discover that, on the patches of the foundations blocked from sunlight for years, was growing wild plants, dotted with little flowers．Puzzlingly, some species were native to Mediterranean countries only.

Most of the destroyed houses had been built during the Roman invasion．Weighed down by piles of bricks and stones year after year, the seeds possibly brought here in Roman times had almost no hope for survival．However, once bathed in the sun, they came alive.

The little seeds were so fragile yet so persevering．Though bricks piled on them many years, they still remained alive．Once exposed to sunshine and rain, they immediately exhibited signs of life．A little seed, lying underground for hundreds of years, still cherished the hope to live on．But what if a man is stuck in a similar situation?

One year, a British expedition was marching through the boundless Sahara sands．With the sun hanging overhead, hot waves of sandy winds were blowing against their faces like hot iron grains．The men were suffering both thirst and anxiety．The last drop of water was gone．Just then, the captain brought out a water bottle, saying, “There is still one bottle of water left．However, no one is to drink any before going out of the desert.”

The bottle of water lent them confidence to get through the desert, and embodied their hope to live on．It was handed down the line of people．This changed into firmness the despair registered on the men’s faces．Finally the men walked out of the desert, shaking off the threat of death．Tears out of joy welled out, and trembling hands were trying to screw off the bottle cap and let out the water, which had supported them spiritually．Now, however, it was sand pouring out—a bottleful of sand!

Was it a bottle of sand that rescued them from the burning sun and the boundless desert? No, it was their firm faith, like a seed that had taken root in their hearts and that finally let them out of the awful desert.
