Trees in cities“live fast but die young” compared to forests in the countryside, warns a new study.
Researchers found that trees in cities die younger than ones in the countryside because of the higher levels of CO2. City -living trees suffer (遭受) a loss of carbon storage (碳储量). That means trees produce less energy from the air.
Lesson 7 Planting Trees
Now researchers say more must be done to deal with the situation. Ian Smith, a PhD student of Boston University in the United States, said, “Cities are in the important position in fighting against rising temperatures and increasing CO2.” “We find that tree planting alone may not be enough to keep and increase city canopy cover (树冠覆盖率). Because of the age and size of the present canopy, efforts to improve and protect tree health are badly needed for increasing city tree cover and canopy cover.”
Lesson 7 Planting Trees
The research team used a model to watch changes among street trees for several planting and management methods. Researchers also used the model to watch tree growth, death and planting rates (率) both among trees in Boston city and forests in the countryside in Massachusetts.
It was discovered that rates of carbon cycling and growth rates among city trees were nearly four times faster than those in the countryside. However, loss of carbon storage and death rates are also higher, especially death rates are more than double higher than those in countryside forests.
Lesson 7 Planting Trees
The study, published in PLOS ONE, has reminded scientists to encourage communities to do more to plant and protect trees. It is important to increase city canopy cover and carbon storage.
Researchers say planting and protecting will be needed to make sure cities can develop h...,but more needs to be done to have a better under－standing of city trees which may be different from countryside forests.

15. According to the passage, which of the following is TRUE _______
A. The more carbon storage loses, the more energy the trees produce from the air.
B. The higher the levels of CO2 are, the harder it will be for the plants to survive.

Lesson 10 Make Your Garden Grow!
Decide where to put the garden. Will it be indoors or outdoors You can start a garden indoors in a few boxes. Check how much sunlight your room gets. Windows that face south and west are good for growing vegetables, as they usually receive enough light. If the room doesn’t get enough sunlight, you will need to set up lights over your plants. For an outdoor garden, you will also need to see how much sunlight the space gets. Most flowers and vegetables need six hours of sunlight a day.

Trees are greatly useful to man in three very important ways.
The first important way is that they provide man with food, wood and other products. Trees provide not only man with food, but also many animals with food. Without trees many animals could not live on the earth. It’s not easy for man to live on the earth, either.
The second important way is that trees give us shade. On a hot summer day, people are looking forward to having a rest under the shade of a tree after they have walked a long way. You can imagine how important the shade of a tree is to man and to animals.
Lesson 8 Why Are Plants Important
The third important way is that trees help to prevent drought (旱灾) and floods (水灾) . However, in many parts of the world, man has not realized the third important way. They cut trees down in large numbers. There will be fewer trees in the future.
People should protect trees, or they will find that they have lost the best friends they had in the end.

Wi thout flowers, many plants would not be able to reproduce (繁殖) and many insects would not be able to get enough food to live. Here are some interesting facts about flowers plants.
● Most plants grow flowers each year, but some take much longer. The century plant (龙舌兰) grows only one flower and then it dies! Even more amazing is a plant from South America called Puya raimondii. It doesn’t grow a flower until it is 150 years old, and after that it dies, too.
Lesson 11 Amazing Plants
● The smallest flowering plant in the world is thought to be the common watermeal (无根萍). Its leaves are only 1 mm across!
● Bamboo has amazing flowering habits. There are many different kinds of bamboo in the world. What is amazing is that all bamboo of the same kind will flower almost at the same time, wherever it is growing! Nobody knows why.
● The white flower of the Amazon water lily (睡莲) is the size of a football, and the flower turns purple after it has been pollinated (授粉).

Can plants eat people Maybe not, but there are many plants that eat meat. Some of them are big, and they can eat small animals. One famous meat-eating plant is the Venus flytrap (捕蝇草).
The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of a book. They can open and close very quickly. Inside the leaves, there are three small hairs. If a fly touches one of the hairs, the leaves close quickly. The fly cannot get out. In about half an hour, the leaves press (压) the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly.
