植物可分为grass 草本植物和tree乔木两大类。一般来说,枝干持续生长一年以上的可归为tree,反之就是grass。
植物的root根埋在土里是为了吸收水分和营养。植物的茎用英语说是stem。但是,一般来说,stalk是指草或花的茎,而trunk则多用于指树木的干。顺着干向上可以看到branch树枝,大的树枝叫做bough粗枝,小的叫做twig细枝。树枝上还长着leaf叶子,到了收获的季节,树枝上还挂满了fruit果实。果实的中心有一个坚硬的core核,里面装有seed种子。
春天一到,所有的植物都开始bud发芽,一段时间后慢慢开出flower花朵。像郁金香这样的观赏花ornamental flower就被归为bloom开花植物。Fruit tree果树上开的花叫做blossom。
如果收到朋友送来的bunch of flowers花束,一定要在petal花瓣wither凋谢之前,把它们插到flower vase花瓶里,这样做才能使花朵开得持久一点。如果你不忍心看到花朵凋谢,那就去买一束artificial flowers人造花吧,放在家里好久都不会坏。
一般树木统称为tree,而个头矮小的则叫做shrub灌木或者bush。wood是指广泛用于建朱方面的木材。
盛夏,大部分的树木逗verdant郁郁葱葱,可是到了秋天,部分树木的叶子会掉光,这类树木就叫做deciduous tree落叶树;另一部分树木四季常青,这类树木就叫做evergreen tree常绿树。
