Chúng ta sống trong một thế giới năng động, và môi trường sống luôn luôn trải qua những thay đổi ở tất cả các cấp độ. Tuy nhiên, những thay đổi tự nhiên thường xảy ra ở tốc độ chậm để tác động đến từng loài có xu hướng nhỏ - ít nhất là trong ngắn hạn
Khi tốc độ thay đổi được tăng tốc đáng kể, có thể không có thời gian để các loài cá thể phản ứng với hoàn cảnh mới, và các hiệu ứng có thể là thảm họa. Tóm lại, đây là lý do khiến mất môi trường sống nhanh chóng được coi là nguyên nhân chính gây nguy hiểm cho loài, và không có lực lượng nào mạnh hơn trong vấn đề này so với con người. Ở một mức độ nào đó, mọi phần của trái đất đã bị ảnh hưởng bởi các hoạt động của con người, đặc biệt là trong thế kỷ qua. Điều này áp dụng trên hầu hết mọi quy mô, từ việc mất vi khuẩn trong đất đã từng hỗ trợ rừng nhiệt đới, đến sự tuyệt chủng của cá và các loài thủy sinh khác trong môi trường nước ngọt bị ô nhiễm, thay đổi khí hậu toàn cầu gây ra bởi việc thải khí nhà kính. Từ quan điểm của một đời người, những thay đổi như vậy có thể khó phát hiện và ảnh hưởng của chúng đối với từng loài có thể khó dự đoán. Nhưng bài học là đủ rõ ràng. Ví dụ, mặc dù nhiều quốc gia đã có kế hoạch trồng nhiều khu rừng nhiệt đới, chúng rất dễ bị phá hủy bởi vì các loại đất mà chúng phát triển rất nghèo trong các chất dinh dưỡng sẵn có. Nhiều thế kỷ có thể được yêu cầu mang lại một khu rừng bị cắt giảm hoặc bị đốt cháy trong không gian vài năm. Nhiều loài động vật và thực vật bị đe dọa nghiêm trọng trên thế giới sống trong các khu rừng như vậy, và chắc chắn rằng một số lượng lớn chúng sẽ biến mất nếu tỷ lệ mất rừng hiện tại tiếp tục. Môi trường sống trên thế giới là không thể thay đổi và tồn tại cố định.

Recycling
In Tokyo, there are five main categories of trash, with multiple (1) subcategories (CATEGORY) and exceptions. Each category is collected only on certain days. The apartment manager puts out the proper cans on the proper days, and if you don't take the stuff out in time, it's like missing a ferry, only (2) smellier (SMELL).
That is the height of (3) irresponsibility (RESPONSIBILITY). The catchall category is (4) combustible (COMBUSTION) waste. This is for stuff that should go to the (5) incinerator (INCINERATE). Plastic is not just any plastic. It has to be (6) recycled (CYCLE) and clean without food stains.
It is your obligation as a citizen to make a good-faith effort to wash food (7) residues (RESIDUE) off the plastic before putting it in the plastic bin. Not all plastic is Plastic, but the paper is the worst. You're supposed to bundle your newspapers and then slip small pieces of paper in between the newspapers to act as (8) separators (SEPARATE). These parcels are then tied up and placed at group collection points for collection by voluntary community groups.
Plans grow(46)in almost every part of the world. We see(47)such plants as flowers, glass, and tree nearly every day. Plants grow high on moutaintops, far in the oceans, and in many deserts and(48)polar regions
Without plants, there could be not life on earth. Man could not live without air of food and so he could not live without plants. The oxygen in the air we breathe comes from plants. The food we eat also comes from plants or from animals that eat plants. We build houses and make many(49)useful products from lumber cut from trees. (50) Much of our clothing is made from the fitbers of the cotton plants.
Scientists belive there are more than 350,000 species of plants, but no one knowns for(51)sure. Some of the smallest plants, called diatoms, can be seen only with a(52)microscope . A drop of the water may hould as many as 500 diatoms. The largest living things are the giant sequoia trees of California. Some of them stand more than 290 feet high and measure over 30 feet wide
Scientist(53)divide all living things into two main groups - plants and animals. It is usually easy to tell the two(54)apart . Almost all kinds of plants stay in one place, but nearly all species of animals move about under their own power. Most plants make their own food from air, sunglight, and water. Animals cannot make their own food. The basic units of all life, called cells, are also different in plants and animals. Most plants have thick wall that(55) contain a material called cellulost. Animal cells dl not have this material.

DAINTREE RAINFOREST
Rainforests are not only 0 ( spectacle)................ but also provide shelter for lover half the species of plants and animals on Earth. The Daintree Rainforest in Queensland, Australia, is the world's 46 (old) oldest rainforest and is a living record of 47 ( evolution) evolutionary change. It receives vast amounts of rainfall in torrential showers that last for a few hours, with bright sunshine the rest of the time. Temperatures in the forest are 48 ( surprise) surprisingly mild thanks to the towering trees. This 49 (tropic) tropical environment has everything from sandy beaches to 50 (impress) impressive plants and flowers.51 (approximate) Approximately 430 types of birds live among these trees, including 13 species not found anywhere else in the world. The forest is also home to 52 (colour) colourful butterflies, owls, huge lizards, and giant treefrogs. It is not 53 (common) uncommon to see Estuarine crocodiles on the riverbanks - in fact, they are a constant threat to 54 ( care) careless swimmers.The Daintree Rainforest is 55 ( like) unlikely to avoid destruction by theoutside world forever. However, it is of vital importance that we try to protect this amazing natural treasure for as long as we can.
