This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals can get their food by eating plants and other animals. Man gets his food by eating plants and animals, too. So animals and man need plants in order to live. This is why there are so many plants around us.There are two kinds of plants: flowering plants and non-flowering plants. Almost all the trees around us are flowering plants. You can know some trees from their flowers and fruit. Non-flowering plants do not grow flowers. You can not see many non-flowering plants around you.If you look carefully at the plants around you, you will find that there are many kinds of plants. Some plants are large and some are small. Most of them are green. Thanks to the plants around us we can live on earth.( )26.We need many plants around us because _.A.plants can grow easilyB.plants are greenC.we can get what we need from plantsD.we like all kinds of plants( )27.There are so many plants around us because _.A.man doesnt need any plantsB.most animals dont eat plantsC.man and animals need plants to liveD.the earth will become more beautiful( )28.There are _ non-flowering plants than flowering plants around us.A.much fewerB.much moreC.much largerD.much better( )29.Which of the following does NOT come from a plant?A.Basket.B.Bread.C.Cabbage.D.Stone forest.( )30.Which is the best title(題目) of this passage?A.Plants around usB.Man and AnimalsC.Live on EarthD.Food and Plants(B)Do you know why different animals or pests (害蟲) have their special colors？Colors on them seem to be used mainly (主要地) to protect themselves.Some birds like eating locusts (蝗蟲), but birds cannot catch them easily. Why? Because locusts change their colors according to the colors of crops (莊稼). When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others, so they have to hide (隱藏) themselves and appear (出現(xiàn)) only at night.If you study animal life, youll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters (獵人). This is because they have colors much like the trees.A kind of fish in the sea can send out a kind of very black liquid (液體) when it faces danger. While the liquid spreads out, its enemies (敵人) cannot find it, so it can escape (逃跑) at once. So it can live long, though it is not strong at all.( )31.From the passage we learn that locusts _.A.are small animalsB.are easily found by birdsC.are dangerous to their enemiesD.change their colors to protect themselves( )32.How can pests with different colors from plants keep out of danger?A.They run away quickly.B.They have the colors much like their enemies.C.They hide themselves by day and appear at night.D.They have to move quietly.( )33.Bears and lions can keep safe because _.A.they have the colors much like the treesB.they move quietlyC.they like brown and grey colorsD.they live in forests( )34.Why can the kind of fish live long?A.Because it is very big and strong.B.Because it can send out a kind of very black liquid to help it escape from its enemies.C.Because it can send out a kind of liquid to kill its enemies.D.Because it swims faster than any other fish.( )35.Which is the best title(標題) of this passage?A.The Change of Colors for Animals and Pests.B.Colors of Different Pests.C.The Main Use of Colors for Animals and Pests.D.Some Animals and Pests.(C)Tom has the most beautiful garden in our town. Many people take part in“The Nicest Garden Competition”each year, and Tom wins every time. Mikes garden is larger than Toms. Mike works harder than Tom and grows more flowers and vegetables, but Toms garden is more interesting. He has made clean paths (小徑) and built a wooden bridge (橋) over a pool.
