Do you love flowers Today I will tell you something about a kind of beautiful flower—sunflowers.

We use sunflowers in different ways. One thing we do with them is to look at them! Many people plant them in gardens because they are so big, bright and colorful. They can also be cut and brought inside. They will last (維持) a long time in a vase (花瓶).
Sunflower seeds are delicious. People, birds, and other animals love to eat sunflower seeds. They can be difficult to be eaten (被吃掉) because of the shell, but they are rich in protein (蛋白質(zhì)) and are good for health. Sunflower seeds also have a lot of oil.

B
Trees are one of the oldest plants of our Earth. They keep the air clean, make less noise pollution, make water cleaner and provide food and building materials.
Just like us, trees change a lot as they grow. At one to three years old, young trees learn how to protect themselves. For example, many trees grow thorns to stop animals from going near.
At the age of four, trees begin to grow very quickly and become strong enough to face many difficulties later in life. At the age of 15, trees become young adults. They grow more slowly and begin to produce flowers and fruit.
When a tree is 20 to 25 years old, it becomes a real adult. The tree reaches its largest size. Not only does the adult tree give us shade (樹蔭), oxygen and natural beauty, it is also a great place for a tree house, or a place for us to read a book. If the adult tree can have a good care, it will go on to live healthily for many years.
Little by little, trees begin to grow older and older and even die. At this time, they still have their important place in nature. When a tree becomes hollow (空心的) or part of it becomes dead, it becomes a home to small animals and a source (來源) of food for many other animals.
In many ways, the life of a tree is similar to our own life experience. When looking at the life of a tree, we learn that each period (時(shí)期) of life brings its own kind of happiness and difficulties. Enjoy every minute of the life of trees and take care of them.

B．Older trees can make great places for people to rest.
C．You can find a lot of flowers and fruit on young adult trees.

43．What’s the structure of the passage (①=Paragraph 1 …)

C
There is a seed (種子). He is so small that nobody wants to look at him. 44
One day, a wind brings him to a field in the sun. He looks around and a spatter of rain comes to him. Then he grows up. Four years later, a man sits under him. The man says, “Thank you for this. 45 ”

At the age of 15, trees become young adults. They grow more slowly and begin to produce flowers and fruit.”可知樹在四歲開始快速生長(zhǎng)，15歲成為年輕的成年樹，生長(zhǎng)更緩慢并開始開花結(jié)果，所以先a后d；根據(jù)“When a tree is 20 to 25 years old, it becomes a real adult.”可知20到25歲成為真正的成年樹，對(duì)應(yīng)c；根據(jù)“Little by little, trees begin to grow older and older and even die.”可知最后樹會(huì)變老并死亡，對(duì)應(yīng)b。所以順序是e-a-d-c-b。故選D。

43．篇章結(jié)構(gòu)題。通讀文章可知，第一段介紹了樹是地球上最古老的植物之一以及樹的作用；第二段到第五段分別介紹了樹在不同生長(zhǎng)階段的特點(diǎn)和變化；第六段總結(jié)，通過樹的生命我們學(xué)到生命的每個(gè)時(shí)期都有自己的快樂和困難，要享受樹生命的每一分鐘并照顧好它們。故選B。
44．C 45．D 46．G 47．B 48．A

44．根據(jù)“There is a seed (種子). He is very small and nobody wants to look at him”可知種子很小，沒人想看他。選項(xiàng)C“所以種子認(rèn)為他不重要。”符合語境，故選C。
