An organism’s environment is all the living and nonliving things that surround and influence the organism(生物体). You are living with many things that make your environment suitable for you to live in. Would that be true if you lived in a swamp(沼泽)?

Environments include biotic parts and abiotic parts. Biotic parts are the living things in an environment: plants, animal, and other organisms. Abiotic parts are the nonliving things. Abiotic parts of an environment include climate, water, earth, light, air and nutrients. The abiotic parts of an environment have an important role. Temperature and amount of water influence which plants and animals can live in a place. An ibis(朱鹮) gets used to living in a warm, wet swamp and cannot live in a hot, dry desert.

An ecosystem is all the organisms living in a place together with their environment. An ecosystem can be huge, such as a large forest or desert. Or it can be small, such as a small pool or a single bush. Each ecosystem has its own collection of living and nonliving things.

A swamp ecosystem is made up of both living and nonliving things. The climate, plenty of water, air, muddy soils are all abiotic parts that make swamps different from other environments. Birds, black bears, trees, bushes, and mosquitoes are all biotic parts of a swamp environment.

1.Biotic parts include many things in an environment except _________.

A. snakes B. strawberry C. wheat D. sand

A. the organisms B. the abiotic parts C. the ecosystem D. the swamp

A. If all swamps disappear, ibis will be endangered.

B. In an ecosystem, abiotic parts are not connected to the living things.

C. An ecosystem can be very big or very small.

D. An ecosystem includes living things along with nonliving things.

5.The best title of this passage is _________.

A. What is an ecosystem? B. An Organism’s Environment

We all know that lying (说谎) is wrong. But do you know that it is bad for both your physical and mental health? A recent study shows that telling fewer lies helps people physically and mentally.

“For ten weeks, 110 people aged from 18 to 71 were tested to see the relationship between the number of lies they told and their health,” said Anita Kelly, a professor at the University of Notre Dame in Indiana. “When they lied more, their health declined,” said Kelly.

Researchers divided the people into two groups. Group A was told to avoid telling any lie for any reason to anyone. They may omit (忽略) the truth, refuse to answer questions, and keep secrets, but they can’t say anything that they know are not true. Group B was not told anything like this.

Over the study period, when people in Group A told fewer lies in a week than they did in other weeks, they experienced fewer health problems such as sore throats and headaches. Professor Linda Stroh said, “When you find that you don’t lie, you have less stress (压力).” The results of past research show that each American tells about 11 lies a week. In both groups, when people lied less during a week, they reported better physical and mental health during that period.

“It’s certainly a good thing to have people be more honest,” said Robert Feldman of the University of Massachusetts. “It may improve our mental health, but I don’t think it can improve our physical health.”

A. 变坏 B. 改善 C. 加强 D. 混乱
