1 . Long ago, Mother Nature gave each tree a different purpose. However, she did not share her reasons with the trees.

Fir Tree(杉树) had many tree friends. In summer, they watched Bird and Squirrel(松鼠)play in the field. Then autumn arrived. The leaves on other trees turned colourful. Fir Tree's leaves stayed green. Fir Tree told Mother Nature that he wanted his leaves to change colours too.

“Be patient,” Mother Nature said. “You will learn your purpose.”

So Fir Tree waited. The temperature dropped. Bird flew south, and Squirrel was nowhere around. All the trees lost their leaves except Fir Tree. Soon it snowed. Fir Tree cried, “Why don’t I change like my friends?”

“Be patient,” Mother Nature replied.” Soon you will get to know your purpose.

Just then, Squirrel appeared. She was cold. She asked if she could build a warm home in branches(树枝). Other trees said no because they had no leaves. But Fir Tree said yes. Squirrel ran up Fir Trees branches. Soon, she was warm, comfortable and asleep.

Fir Tree was happy that his green leaves provided a warm home for animals in winter. He finally understood his purpose.

Han Dan comes from China. She is a clever and beautiful girl. She studies in middle school. She has four pen pals . They are from different countries and like different animals. Linda is from America. Her favorite animal is the penguin. The penguin likes ice very much. Lily comes from Australia. The koala is her favorite animal. The koala likes to eat leaves. And it sleeps during the day, but it gets up at night. Bob is from India. His favorite animal is the elephant. Grass is the elephant’s favorite food. Tom is a Canadian boy. He likes the tiger best. The tiger likes to eat meat. What is Han Dan’s favorite animal? It is the pandas. Bamboo is panda’s favorite.

3 . Eight years ago, 1-week-old Diandian was left behind. When people found her in the reeds (芦苇) of a lake, she looked too weak to survive. Now she is the mother of three milu, thanks to the workers’ attention and care at the East Dongting Lake National Nature Reserve.

Li is the president of a milu conservation association in Yueyang and head of a local milu and bird rescue center, where 11 deer, including Diandian, have their families. Li and his workmates need to work extra hours to take care of the animals from March until mid-May. He remembers March 18 this year. He fed Diandian some fresh shoots and leaves for breakfast as usual, and moments later when he returned, a newborn milu was right beside her. Since it is her third baby and born in the third month of the year, people named it Sansan, referring to “three-three”. Li has developed a deep affection for milu and made up his mind to protect them. “As our country is paying more attention to environmental and wildlife protection, people are increasingly aware that milu are state-protected animals,” Li said.

Milu habitats (栖息地) are usually centered around water, and fishing equipment that used to be a threat to the animals is no longer seen in nature reserves. On May 27, a team of experts went to watch milu near Dongting Lake. It takes time and luck to meet one and count them especially when they live in the thick reeds that are 4 to 5 meters tall. The team leader Song, saw a milu for the first time when he was studying for his doctorate in zoology early in 2009. Since then, he has helped protect the habitats at Dongting Lake. As the flood season is coming, Song and his workmates will go around the lake area day and night to save deer in trouble, and provide feed for the animals when needed.

As the environment improves in and around Dongting Lake, China’s second-largest freshwater lake, the wetland has become cover once again for wildlife. “We will continue to protect these rare animals and their living environment,” Song said.

6 . Space vegetables are grown from seeds (种子). They have been taken to and brought back from outer space. The seeds are influenced by the radiation (辐射) and low gravity (重力) in outer space. When they are brought back to the earth, these seeds produce vegetables that are bigger, healthier and more nutritious (有营养的) than normal vegetables. People needn’t worry, because space vegetables are actually very healthy.

Space vegetables are better for you than normal vegetables. (B) _________ example, space tomatoes stay fresh for twenty days, which is one week longer than normal tomatoes.

After genetically modified (转基因) food came into the market, people worried that they were eating unknown things. Unlike genetically modified food, space vegetables have not been genetically changed.

9 . Australian Green Tree Frog

The Australian green tree frog is a large species of frog. It measures up to 10 centimeters in length. Females are generally larger than males. These frogs are usually green or brown with white underparts.   They have small discs on   their toes, which allow them to climb steep and slippery objects. Their lifespan   is around 16 years, and they are often kept as pets. They are nocturnal (夜行的), and sleep in dark, damp places during the day.

The Australian green tree frog prefers wet, tropical environments and are often found high in the trees.

These fogs are native to northern Australia and southern New Guinea.

A lot of insects are eaten by the Australian green tree frog. It catches them with its long, sticky tongue. Females lay between 1000 and 3000 eggs in a jelly-like mass that floats on top of shallow water. These   eggs eventually sink to the bottom, where they attach to vegetation.

The Australian green tree frog is declining( 下降) in numbers, mainly because of habitat destruction and a fungus(真菌) that attacks their skin.
