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（層），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（腐殖質(zhì)），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．a(chǎn)nd rivers．Once in the soil or rock，it is called groundwater．Gravity pulls groundwater through the soil in a process called percolation（滲透）．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．a(chǎn)nd 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

I realize this the first time after my six-year-old daughter, Kayla, went to play there. When Kayla came home, she was very about her day. She told me they had baked cookies, played games and done art projects. But she was excited about her finger-painting project.
“Mom, guess what?”said Kayla, all smiles. “I learned how to colors today! Blue and red make purple, and yellow and blue make green! And Michelle with us.”
To my great my child had learnt about color from a blind friend!
Then Kayla continued, “Michelle told me my showed joy, pride and a sense of accomplishment. She really what I was doing!’’ Kayla said she had never felt how good finger paints felt Michelle showed her how to paint without looking at her paper.
I realized Kayla didn’t know that Michelle was blind. It had just never come up in conversation.
When I told her, she was for a moment. At first, she didn’t believe me. “But Mommy, Michelle knew exactly what was in my picture!” Kayla . And I knew my child was because Michelle had listened to Kayla describe her artwork. Michelle had also heard Kayla's pride in her work.
We were silent for a minute.Then Kayla said slowly, “You know, Mommy, Michelle really did ‘see’ my picture. She just used my .’’ Indeed, she uses a special type of “vision” that all mothers have.

It was reported last week that developers could take photos from Apple mobile and Google Android devices without the phone owners knowing that the images were being taken. In Apple’s case, developers can also obtain the location information for each photo.
Senator(參議員) Charles Schumer said in a telephone interview that his office had spoken with officials at both Apple and Google on Monday.
“We asked them if they could find a way on their own to prevent Apple from having access to private information,” Mr. Schumer said. “They were friendly and open to the idea that this ought to be changed.”
On Sunday, Mr. Schumer said that he planned to send a letter to the Federal Trade Commission asking the agency to investigate Apple and Google after the privacy concerns came to light. Claudia Bourne Farrell, an F.T.C. spokeswoman, said the agency had received the letter but she could not comment further.
“It worries people to think that one’s personal photos, address book, and who knows what else can be obtained and even posted online without permission,” Mr. Schumer wrote in his letter to the F.T.C. “If the technology exists to open the door to this kind of privacy invasion（入侵）, then surely technology exists to close it, and that’s exactly what must happen.”
Mr. Schumer said if Apple and Google could not come to an agreement to fix the problem, then he would be forced to take the issue further.
He said other companies had been willing to work with his office to fix issues. “I’m optimistic that we can get this changed without any regulation,” he said. “If it’s not changed, then we’ll turn to the F.T.C., and if that doesn’t work then we’llconsider legislative approach.”

Many people believe Henry Ford invented the automobile (汽車). But Henry Ford did not start to build his first car until 1896. That was eleven years after two Germans developed the world's first automobile. Many people believe Henry Ford invented the production line that moved a car's parts to the worker, instead of making the worker move to the parts. That is not true, either. Many factory owners used methods of this kind before Ford. What Henry Ford did was to use other people's ideas and make them better. And he made the whole factory a moving production line.
In the early days of the automobile, almost every car maker raced his cars. It was the best way of gaining public notice. Henry Ford decided to build a racing car. Ford's most famous race was his first one. It was also the last race in which he drove the car himself.
The race was in 1901, at a field near Detroit. All of the most famous cars had entered, but only two were left: the Winton and Ford's. The Winton was famous for its speed. Most people thought the race was over before it began.
The Winton took an early lead. But halfway through the race, it began to lose power. Ford started to gain. And near the end of the race, he took the lead. Ford won the race and defeated the Winton. His name appeared in newspapers and he became well-known all over the United States. Within weeks of the race, Henry Ford formed a new automobile company. In the 1903, a doctor in Detroit bought the first car from the company. That sale was the beginning of Henry Ford's dream. Ford said: "I will build a motor car for the great mass of people. It will be large enough for the family, but small enough for one person to operate and care for. It will be built of the best materials. It will be built by the best men to be employed. And it will be built with the simplest plans that modem engineering can produce. It will be so low in price that no man making good money will be unable to own one."
The Model T was a car of that kind. It only cost $850. It was a simple machine that drivers could depend on. Doctors bought the Model T. So did farmers. Even criminals.They considered it the fastest and surest form of transportation. Americans loved the Model T. They wrote stories and songs about it. Thousands of Model T's were built in the first few years.
