走一步，再走一步（11分）

我从石架向下望，感到头晕目眩；我绝对没法爬下去，我会滑倒摔死的。但是，往崖顶的路更难爬，因为它更陡，更险。我听见有人啜泣，正纳罕那是谁，结果发现原来是我自己。

时间一分一秒地过去，暮色开始四合。在一片寂静中，我伏在岩石上，恐惧和疲乏使我全身麻木，不能动弹。

暮色苍茫，天上出现了星星，悬崖下面的大地越来越暗。这时，树林里有一道手电光照来照去。我听到了杰利和我父亲的声音!父亲的手电光照着我。 “下来吧，孩子，”他带着安慰的口气说，“晚饭做好了”。

“我下不去!”我哭着说，“我会掉下去，我会摔死的!”

“听我说吧，”我父亲说，“不要想着距离有多远。 你只要想着你是在走一小步。你能办得到的。眼睛看着我电筒的光照着的地方，你能看见石架下面那块岩石吗?”

我慢慢地把身体移过去。“看见了。”我说。

“好，”他对我说，“现在你把左脚踏到那块岩石上。不要担心下一步。听我的话。”

这似乎能办得到。我小心翼翼地伸出左脚去探那块岩石，而且踩到了它。我顿时有了信心。 “很好，”我父亲叫道， “现在移动右脚， 把它移到右边稍低一点的地方， 那里有另外一个落脚点。 ”我又照着做了。 我的信心大增。 “我能办得到的。”我想。

我每次只移动一小步，慢慢爬下悬崖。 最后， 我一脚踩在崖下的岩石上， 投入了父亲强壮的手臂中。 我先是啜泣了一会儿， 然后， 我产生了一种巨大的成就感。 这是我永远忘不了的经历。

我曾屡次发现， 每当我感到前途茫茫而灰心丧气时，只要记起很久以前我在那座小悬崖上所学到的经验， 我便能应付一切。 我提醒自己， 不要想着远在下面的岩石， 而要着眼于那最初的一小步， 走了这一步再走下一步， 直到抵达我所要到的地方。 这时， 我便可以惊奇而自豪地回头看看， 自己所走过的路程是多么漫长。

British scientists are breeding a new generation of rice plants that will be able to grow. in soil con­taining salt water. Their work may enable abandoned farms to become productive farms once more.

Tim Flowers and Tony Yeo, from Sussex University’s School of Biological Sciences,. have spent several years researching how crops, such as rice, could be made to grow in water that has become salty. The pairs have recently begun a three-year programme, funded by the Biotechnology and Bio­logical Sciences Research Council, to establish which genes enable some plants to survive salty condi­tions. The aim is to breed this capability into crops, starting with rice.

It is estimated that each year more than 10 million hectares (公顷) of agricultural land are lost because salt gets into the soil and stunts(防碍生长) plants. The problem is caused by several factors. In the tropics, mangroves that create swamps (沼泽) and traditionally formed barriers to sea water have been cut down. In the Mediterranean, a series of droughts have caused the water table to drop, allowing sea water to seep (渗透) in. In Latin America, irrigation often causes problems when water is evaporated by the heat, leaving, salt deposits behind.

Excess salt then enters the plants and prevents them functioning normally. Heavy concentrations of minerals in the plants stop them drawing up the water they need to survive.

To overcome these problems. Flowers and Yeo decided to breed rice plants that take in very little salt and store what they do absorb in cells that do not affect the plants’ growth. They have started to breed these characteristics into a new rice crop, but it will take about eight harvests before the resul­ting seeds are ready to be considered for commercial use.

Once the characteristics for surviving salty soil are known, Flowers and Yeo will try to breed the appropriate genes into all manners of crops and plants. Land that has been abandoned to nature will then be able to bloom again, providing much needed food for the poorer countries of the world.
