動(dòng)植物間的差異
There are several characteristics which distinguish plants from animals.
Generally speaking, plants are able to manufacture their own food, by using substances in the environment through the process which is known as photosynthesis. They can grow very well if they have enough sunshine, rainfall and fertilizer. In contrast, all animals, including man, get their food either directly from the plants or indirectly by eating animals which feed on plants or other animals. Animals, therefore, need a wide range of food than plants.
Plants are stationary. They do not have the power to move. Animals, on the other hand, can usually move about. Consequently, plants appear to be less sensitive then animals although they respond in some ways to light, heat, physical contact and other stimuli.
Plants are usually green. Animals, however are very diverse in external appearance. They may appear in any color you can think of.
[點(diǎn)評(píng)] 這篇描述文用對(duì)比的方法對(duì)植物與動(dòng)物之間的不同點(diǎn)逐一作了描述。文中所用轉(zhuǎn)接詞in conlrast,on the other hand和however使讀者對(duì)這些不同點(diǎn)一目了然。

動(dòng)植物間的差異
有許多特征可將植物和動(dòng)物區(qū)分開來。
一般說來,植物可以自己生成它們的食物。它們可以通過光合作用,用環(huán)境中的物質(zhì)來實(shí)現(xiàn)這一點(diǎn)。如果有充足的陽光、雨水和肥料,它們便能茁壯成長(zhǎng)。相比之下,動(dòng)物,包括人在內(nèi),要么直接從植物那里獲取食物,要么間接地從以植物或其他動(dòng)物為生的動(dòng)物那里獲取食物。因此,動(dòng)物比植物需要更廣泛的食物。
植物是靜止的,它們沒有移動(dòng)能力,而動(dòng)物卻可以四處流動(dòng)。因此,雖然植物也以某種方式對(duì)光、熱、接觸及其他刺激作出反應(yīng),但它們卻沒有動(dòng)物那么敏感。
植物一般為綠色,而動(dòng)物的外表色澤則五花八門,它們可以是你能想像到的任何顏色。
