Have you ever noticed tiny raised areas on the branches of a tree? These may have been insects. These small insects feed on tree sap (汁液). Insects on urban trees are notably more abundant than those on rural trees. As a result, urban trees suffer from heavy infestations (害虫横行), and are often unhealthy or die. To protect and restore urban trees’ health, we need to determine the factors that make these tree pests more successful in urban habitats.
Living organisms interact closely with their environment. The warmer, more drought-stressed trees harbor more successful pests than cooler, less drought-stressed trees. As cities and natural habitats become hotter and drier, damaging insects will become more abundant on urban trees.
Trees within urban forests are valuable economically and for the environmental sustainability (可持续性) of the region. More than half of the world’s population lives in cities. Across the globe, people are moving into cities at a faster rate than ever. Rapid growth may turn cities into places with harder conditions. Although cities are primarily made of buildings, roads, parking lots, and vehicles, there are still plants in them. The trees within a city are referred to as the urban forest. Urban forests offer very big benefits to human and environmental health. They improve air and water quality, provide habitat for wildlife, cool down temperatures and beautify our environment. They make cities livable.
However, being a city tree is not easy. Heat released by human activities is trapped in cities. As a result, temperatures in urban areas are often warmer than their surrounding rural areas. We call this urban warming or the urban heat island effect. Urban habitats are mostly made of surfaces of asphalt (沥青) and concrete. These surfaces reduce the amount of rainwater that reaches tree roots. As a result, urban forests may suffer, which can negatively affect people and the environment.
What can we do to restore urban forests? Regular irrigation when possible may help keep pest populations under control. Planting tree species that are suitable to handle heat and drought stress would also reduce the occurrence of insect pest outbreaks.
1.What makes tree pests more successful in the city than in rural areas?
A.The warmer and rainy habitat.
B.The hotter and drier habitat.
C.The cooler and drier habitat.
D.The hotter and rainy habitat.
2.Urban forests make cities livable by .
A.providing people enough clean water
B.improving the living environment
C.offering people economic benefits
D.lowering the temperatures
3.According to the text, what results in the city trees’ suffering?
A.Natural disasters.
B.Invisible forces.
C.Human activities.
D.Natural evolution.
4.What would be the best title for the text?
A.The Importance of the Urban Trees

Have you ever noticed the colour of the water in a river or stream after a heavy rainfall? What do you think caused this change in colour? It is soil that has been washed into the river from the riverbank or from t}le nearby fields．
Components of Soft
Soil is made up of a number of layers（层），each having its own distinctive colour and texture．The upper layer is known as the litter．It acts like a blanket．limiting temperature changes and reducing water loss．The topsoil layer is made up of small particles of rock mixed with rotten plant and animal matter called humus（腐殖质），which is black and gives the topsoil its dark colour．This layer is usually rich in nutrients，oxygen，and water．Below the topsoil is the subsoil，a layer that contains more stones mixed with only small amounts of organic matter．This layer is lighter in colour because of the lack of humus．Beneath the soil lies a layer of bedrock．
Soil forms from the bottom up．Over time bedrock is attacked by rain, wind，frost, and snow．It is gradually broken down into smaller particles in a process called weathering．Plants begin to grow，and rotten materials enrich the topsoil．Most of the soil in Eastern Canada．for example．Was formed from weathered rock that was exposed when the ice disappeared l2．000 years ag0．
Water Beneath the Soil
Surface water collects and flows above the ground in lakes．ponds．and rivers．Once in the soil or rock，it is called groundwater．Gravity pulls groundwater through the soil in a process called percolation（渗透）．Eventually the water reaches a layer called the water table．Under this is bedrock through which water cannot percolate．
As water percolates downward，it dissolves organic matter and minerals from the soil and carries them to deeper layers．This causes a serious problem because plants require these nutrients for growth.
Soil pH
Soil can be acidic．neutral．or basic．The pH of the soil is determined by the nature of the rock
from which it was formed．and by the nature of t}le plants that grow and rot in it．
The acidity of rain and snow can lower the pH of the groundwater that enters the soil．By burning fossil fuels such as coal，oil and gasoline，humans have been contributing to higher levels of acidity in many soils．When fossil fuels are burned．gases are released into the air and then fall back to earth as acid rain．Acid soil increases出e problem of carrying nutrients to lower soil levels．As nutrients are removed，soil is less fertile．Plants grow more slowly in acidic soil，and also become easily attacked by diseases．
1.The layer of soil that provides necessary nutrients for plant growth is called．
A．1itter B．topsoil C．humus D．subsoil
2.According to the text．which of the following is NOT true?
A．Soil forms from weathered rock on the earth surface．
B．The deeper layer of soil is darker in colour than t}le surface soil．
C．Air pollution is partially responsible for acid soil．
D．Groundwater tends to carry away nutrients for plant growth．
3.We can infer from the passage that the water table lies________．
A．between the topsoil layer and the subsoil layer
B．in the subsoil layer above bedrock
C．between the subsoil layer and bedrock
D．in the bedrock layer beneath the subsoil
4.The underlined word “dissolve” is used to express the idea that organic matter and minerals from soil are ________．
A．rushed away into the river
B．cleaned and purified by water
C．destroyed and carried away by water
D．mixed with water and become part of it

Have you ever noticed how families on TV always find time to eat meals together? In reality, people today are than ever before and getting the whole family together for an evening meal is often , as all members of the family have their own activities to get on with. For most of us, sitting down together at the table is a thing of the past, but what effect does this have on family members and the relationships between them?
One of the most important of eating together as a family is that the family has a chance to communicate with one another in a social environment. Many families that the evening meal is the best time to discuss problems and share experiences. “Eating together makes us feel , and we often have our most useful conversations at these times,” says Jane Digby, mother of three.

Furthermore, eating together gives a sense of security. Family psychotherapist (心理治疗专家) Sue Taylor believes that children who eat with their are far more confident as well as much more faithful to their families than children who don’t.
In spite of the many advantages of eating together, the of modern life make it almost impossible for many people to do so. However, Sue Taylor insists that we should try to make for family meals. “Mealtimes are the most valuable time a family can spend together,” she says. “If you can’t eat together every day, why not and eat together three or four times a week? It really is worth the effort.”

Have you ever noticed that the more you have the more you want? Let’s face it. Thinking our life is good enough doesn’t come naturally to many people. When we have high expectations of everything in life we will run into disappointment. Only when we are aware that needs are different from desires can we live with satisfaction. Here are a few ideas to help you be happier with what you have and who you are.
Focus on what you are thankful for. Most people want things to be better than they are, or when things are going well, we forget to appreciate what we have. Learn to reflect on how much better things are than they could be. Focus on what you are thankful for. Write down 5 things you are grateful for right now.
When we hold onto regrets from decisions we have made, it can really poison our well-being. Many people regret something they can no longer change, which ends up holding them back from moving forward in a more positive manner. What happened in the past is done and gone, so work to stay present and be mindful of the current moment to find more joy and fulfillment.
When we use other people as the measuring stick for our personal success and quality of life we are likely to be less satisfied. Social comparisons can provide useful information when we try to learn from others, but they also hold our perspective in a discontented position. Compare yourself less with others so you can be satisfied more.
When you are focused on your big ambitions and future goals you might elide the daily pleasures that surround you. Learn to slow down and absorb the wonder and beauty around you. Stay present and focus on the task you’re undertaking at the moment. Don’t let the life pass you by because you’re always on the go and distracted by ambition.
Practice looking at life through the lens of contentment and it will become more natural.
1.How can we live with contentment?
A. To change our lifestyle.
B. To have a motivation in life.
C. To give less attention to what we are grateful for.
D. To realize the difference between needs and desires.
2.What’s the main idea of Paragraph 3?
A. Make wise decisions.
B. Know the present situation
C. Let go of regrets.
D. Remember the past.
3.The underlined word “elide”(in Paragraph 5) probably means “__”.
A. enjoy B. change C. create D. neglect
4.What should you do to put yourself in a good mood?
A. Make time for simple pleasures.
B. Learn from successful people.
C. Focus on your future goals.
D. Create chance to learn more.
