谢谢! 第一题与我的理解一致. 因为 non-living things also move when the wind blows.

第二题, 我们原 ...

答案应该是 (2) The plant will only make food at the adult stage.

答案（4）看起来正确，但严格来说seed leaves provide food for the seedling （或embryo）， developing seed这个说法不太准确和严谨。

谢谢！我又查了课本（MY PALS），在19页，它说到：When leaves develop, the young plant starts making its own food....... As the young plant grows into an adult plant, more leaves develop to help make food. 所以感觉（2）也不那么对。

Which one of the following statements about a plant is true?

(1) The roots will provide food and water for the plant.
(2) The plant will only make food at the adult stage.
(3) The young plant will bear fruit before it bears flowers.
(4) The seed leaves provide food for the developing seed.

我选1，因为root的功能之一是储藏食物。在没有阳光时root就会provide food to the plant.

The four major functions of roots are 1) absorption of water and inorganic nutrients, 2) anchoring of the plant body to the ground, and supporting it, 3) storage of food and nutrients, 4) vegetative reproduction.

不过小学的科学题确实是比较刁钻，小学的科学教材也有矛盾的地方，如My Pal plants and their parts P29, "Some roots store food for the plant", P33的 At a glance里又说 Roots which store food for the plant.

嗯， 有道理， 看来还是（4）比较靠谱。 其实， 我从来没看过孩子的科学课本。。。

很多国家把plant的life cycle分为4个阶段, 即seed，seedling， young adult plant和adult plant.  Young adult plant和adult plant的区别就在于前者get food from seed leave, 而后者通过光合作用来获取能量。新加坡的这种3-stage life cycle说法比较独特，让我完全搞不清young plant stage结束的标志是什么！

还是请老师解释一下为什么正确答案不是4吧。

好的，谢谢！等一下问一下老师。

如果使用“AS WELL AS".那么是已前詞為主。道理與用法跟　"TOGETHER WITH" 是一樣的。
