Starch will be detected on Leaf B because it was exposed to the sunlight for several hours.Photosynthesis will generate starch from absorbing the sunlight.Leaf A will not contain starch because it was covered by a black bag,and therefore it could not absorb any sunlight.
下面是一株没有淀粉的植物。叶片A被黑袋遮住。然后把植株放在阳光下几个小时。预测并解释一下结果－－－是否叶片A和叶片B会被测出淀粉。
叶片A被黑袋遮光，但叶片B没有
Leaf B will be detected contain starch, because of photosynthesis(光合作用), and Leaf A will be no strach, because...

这是关于“绿叶在光下制造淀粉的实验”
参见人教版网上初中生物实验步骤：http://www.pep.com.cn:82/200406/ca453307.htm
我的翻译：下面的是不含淀粉的植物（译者注：已经过饿处理）。叶子A用黑袋遮住，然后将该植物放在阳光下（进行光合作用）几个小时，预测并解释一下实验结果：叶子A还是B能检测到淀粉。
注：叶片A用黑袋遮住，但叶片B没有

楼上翻的相当好了。
2nd.楼主应该更清楚地注明本意是让诸位用英语表达一下预测的实验结果并分析原因，2楼正解
