　　Cicadas(蝉) that appear from underground only once every 17-years are making big news in the US. The first signs are little holes in parks and fields. Then, big, red-eyed bugs start crawling(爬) out. Thousands of these black, winged insects cover sidewalks, mailboxes, tree branches, and roofs across certain areas of America.

　　Many insect lovers are going out to parks to observe what scientists believe to be the largest emergence of an insect group in history. But you don't have to live in the US to study the amazing bugs that inhabit our world. Summer is coming. With it come warm days and many chances to have a look at bugs. These creatures keep our ecosystems(生态系统) running and make up the majority of our planet's population!

　　Many people use the words “bugs” and “insects” to refer to anything with more than four legs. But an insect actually has six legs, a three-part body, and an exoskeleton, which is a skeleton(骨骼) on the outside of its body. Ants, butterflies and cicadas are all insects.

　　Insects keep our environment working by recycling garbage and dead plants. They serve as food for animals, and pollinate(授粉) plants. Doctors have even found ways of using them in medical treatments to help sick people.

　　Tracking down insects to watch can be as simple as going to your local park to look for ants, or as complicated as walking out into the woods to find rare beetles(甲虫) Just look carefully and be patient, and something will turn up.

　　If you want to do more than just watch, you can collect bugs. Take along a butterfly net to catch flying insects and tweezers(镊子) to pick up bugs. Take clean, empty food jars with small air holes poked(戳) in the lids, so you can keep the bugs for a little while, perhaps overnight.

　　Great creatures to look out for during summer include beetles, butterflies and dragonflies(蜻蜓)．However, creatures to watch but not disturb are spiders(蜘蛛) , bees, wasps(黄蜂) , and centipedes(蜈蚣)．All of them may leave a painful bite if you touch them and some bites can be dangerous.

　　When handling and watching the insects you find, remember: they may look different from us, but they have many of the same feelings, such as fear and pain. Have a look, but no poking or pinching(捏) , please!

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．

67．The layer of soil that provides necessary nutrients for plant growth is called．

A．1itter    B．topsoil    C．humus D．subsoil

68．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．

69．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

70．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

One of our biggest fears nowadays is that our kids might some day get lost in a “sea of technology”rather than experiencing the natural world.Fear-producing TV and computer games are leading to a serious disconnect between kids and the great outdoors,which will change the wild places of the world,its creatures and human health for the worse,unless adults get working on child’s play.

Each of us has a place in nature we go sometimes,even if it was torn down.We cannot be the last generation to have that place.At this rate,kids who miss the sense of wonder outdoors will not grow up to be protectors of natural landscapes.“If the decline in parks use continues across North America,who will defend parks against encroachment(蚕食)？”asks Richard Louv,author of Last Child in the Woods.

Without having a nature experience,kids can turn out just fine,but they are missing out a huge enrichment of their lives.That applies to everything from their physical health and mental health,to stress levels,creativity and cognitive(认知的)skills.Experts predict modern kids will have poorer health than their parents—and they say a lack of outside play is surely part of it:research suggests that kids do better academically in schools with a nature component and that play in nature fosters(培养)leadership by the smartest,not by the toughest.Even a tiny outdoor experience can create wonder in a child.The three-year-old turning over his first rock realizes he is not alone in the world.A clump of trees on the roadside can be the whole universe in his eyes.We really need to value that more.

Kids are not to blame.They are over-protected and frightened.It is dangerous out there from time to time,but repetitive stress from computers is replacing breaking an arm as a childhood rite(仪式)of passage.

Everyone from developers,to schools and outdoors’ citizens,should help regain for our kids some of the freedom and joy of exploring,taking friendship in fields and woods that cement(增强)love,respect and need for the landscape.As parents,we should devote some of our energies to taking our kids into nature.This could yet be our greatest cause.

The main idea of Paragraph 2 is that_______.

A.kids are missing the sense of wonder outdoors

B.parks are in danger of being gradually encroached

C.Richard Louv is the author of Last Child in the Woods
