世界節(jié)假日博覽 第70期:珍惜樹木日

April 14 is Plant Appreciation Day (PAD). This is when you appreciate just how important plants are to us. Few of us ever stop to think just how vital plants are to our survival. Without them, we wouldn’t be here. Plants change the CO2 in the air into oxygen. No plants, no oxygen. Plants also improve our daily lives. Most of us have a plant or many plants we like to look after. Some of us even talk to our plants. On PAD, say some nice things to the plants in your life, or treat them to some plant food. The PAD website has a few other suggestions, such as growing your own vegetables and giving them to the poor. Another idea is to plant a tree for every year you’ve been on the planet. Plants are so important for our future.
4月14日為珍惜樹木日。認識到樹木對人類的重要性。很少有人會意識到樹木對于人類生存的重要性。沒有它們，就不會有人類。植被能夠吸入二氧化碳，釋放氧氣。沒有植物就沒有氧氣。植物還能改善我們的日常生活。許多人種植植物。有些人甚至與植物講話。在這天，你可以向植物說些“好話”，或是給它們加點肥料。在“珍惜樹木日”網(wǎng)站上還有一些其它建議，例如種植蔬菜，贈予窮人。另一個是每年種一棵樹。樹木對我們的未來至關重要。


What are plants exactly? They don’t all grow in pots. Plants are living organisms belonging to the Plantae kingdom. They include trees, bushes, vines, ferns, grasses, herbs, mosses, and green algae. People who study plants are called botanists. They say there are 350,000 species of plants in the world. Plants are important for all of our food. We eat fruit, vegetables and grains, and the animals we eat also eat plants. We also need plants to breathe. Plants have a system called photosynthesis which provides us with oxygen. Plants also provide us with materials for building things, like wood; and medicines. Even the energy we use is from plants. Oil is a fossil fuel from plants that died millions of years ago. We really need to appreciate plants more.
究竟什么是樹木？它們不全長在花盆里。植物是植物王國中的生命體。它們包括樹木、灌木、藤本植物、蕨類植物、草、草本植物、苔蘚以及綠藻類植物。研究植物的人被叫作植物學家。他們認為全球有35萬種植物。植物是重要的食物來源。我們需要食用水果、蔬菜、谷物，我們所食用的家禽也需要植物。我們還需要植物來呼吸。植物有一個名叫“光合作用”的系統(tǒng)，它能夠產(chǎn)生氧氣。植物還能為建筑提供材料，例如木頭；以及藥品。我們所需要的能源甚至也來源于植物。數(shù)千年前的植物形成了化石燃料。我們真的需要珍惜植物。
