Several yards away，Frank，43，and his girlfriend，Jennifer，found a spot close to where the front of the train would stop. They were deep in discussion about a house they were thinking of buying.
But when he heard the scream，followed by someone yelling，“Oh，my God，she fell in!” Frank didn’t hesitate. He jumped down to the tracks and ran some 40 feet toward the body lying on the rails. “No! Not you! ”his girlfriend screamed after him.
She was right to be alarmed. By the time Frank reached Lisa，he could feel the tracks shaking and see the light coming. The train was about 20 seconds from the station.
It was hard to lift her. She was just out. But he managed to raise her the four feet to the platform so that bystanders could hold her by the grins and drag her away from the edge. That was where Lisa briefly regained consciousness，felt herself being pulled along the ground，and saw someone else holding her purse.
Lisa thought she’d been robbed. A woman held her hand and a man gave his shirt to help stop the blood pouring from her head. And she tried to talk but she couldn’t，and that was when she realized how much pain she was in.
Police and fire officials soon arrived，and Frank told the story to an officer. Jennifer said her boyfriend was calm on their 40-minute train ride downtown—just as he had been seconds after the rescue，which made her think about her reaction at the time. “I saw the train coming and 1 was thinking he was going to die，”she explained.
41. What was the most probable cause for Lisa’s weakness?
A. She had run a long way.
B. She felt hot in the subway.
C. She had done a 1ot of work.
D. She had donated blood the night before.
42. Why did Jennifer try to stop her boyfriend?
A. Because they would miss their train.
B. Because he didn’t see the train coming.
C. Because she was sure Lisa was hard to lift.
D. Because she was afraid the train would kill him.
43. How did Frank save Lisa?
A. By lifting her to the platform.
B. By helping her rise to her feet.
C. By pulling her along the ground.
D. By dragging her away from the edge.
44. When did Lisa become conscious again?
A. When the train was leaving.
B. After she was back on the platform.
C. After the police and fire officials came.
D. When a man was cleaning the blood from her head.
45. The passage is intended to _____________
A. warn us of the danger in the subway
B. show US how to save people in the subway
C. tell US about a subway rescue
D. report a traffic accident

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．
小题1:The layer of soil that provides necessary nutrients for plant growth is called．
| A．1itter | B．topsoil | C．humus | D．subsoil |
| 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． |
| 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 |
| 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 |
71 Make a study time and have it at the same time every day. This will help your kids to learn to schedule their day and will give them a sense of control over how they spend their time.
Allow them to study in blocks of time, such as for half an hour with a five-minute break in the middle. 72 Ideal （理想的）study times are after dinner or right after school before dinner.
Never allow your children to study in front of the television, as that will encourage passive activity. 73
You’ll also need to help your kids find the right place to study. After you’ve set up a good study time for little learners, set up a good place where they can get those creative juices flowing.
74 Make sure there is a table or a desk and a comfortable chair.
75 This includes helping them out with their homework sometimes and being there for them with the answers to any questions. The input you give your children during study periods will help form a bond and help make studying enjoyable.

It was always thought that Treasure Island was the product of Robert Louis Stevenson’s imagination. ___36___，recent research has found the true story of this exciting work.
Stevenson, a Scotsman, had lived 37 for many years in 1881 he returned to Scotland for a 38 . With him were his American wife Fanny and his son 39 .
Each morning Stevenson would take them out for a long 40 over the hills. They had been 41 this for several days before the weather suddenly took a turn for the worse, Kept indoors by the heavy rain. Lloyd felt the days 42 . To keep the boy happy Robert asked the boy to do some 43 .
One morning, the boy came to Robert with a beautiful map of an island. Robert 44 that the boy had drawn a large cross in the middle of 45 . “What’s that?” he asked “That’s the 46 treasure “said the boy Robert suddenly 47 something of an adventure story in the boy’s 48 While the rain was pouring, Robert sat down by the fire to write a story. He would make the 49 a twelve-year-old boy just like Lloyd. But who would he the pirate（海盗）?
Robert had a good friend named Henley, who walked around with the 50 of a wooden leg. Robert had always wanted to 51 such a man in a story 52 Long John Silver the pirate with a wooden leg, was 53 .
So thanks to a 54 .September in Scotland a friend with a wooden leg and the imagination of a twelve-year-old boy we have one of the greatest 55 stories in the English language.

Self-image is your own mind’s picture of yourself. This image includes the way you look, the way you act, the way you talk and the way you think. Interestingly, our self-images are often quite different from the images others hold about US. Unfortunately, most of these images are more negative than they should be. Thus changing the way you think about yourself is the key to changing your self-image and your whole world.
The best way to defeat a passive self-image is to step back and decide to stress your successes. That is, make a list if you need to, but write down all of the great things you do every day. Don’t allow doubts to occur in it.
It very well might be that you are experiencing a negative self-image because you can’t move past one flaw or weakness that you see about yourself. Well, roll up your sleeves and make a change of it as your primary task. If you think you’re silly because you aren’t good at math, find a tutor. If you think you’re weak because you can’t run a mile, get to the track and practice. If you think you’re dull because you don’t wear the latest trends, buy a few new clothes. But remember, just because you think it doesn’t mean it’s true.
The best way to get rid of a negative serf-image is to realize that your image is far from objective, and to actively convince yourself of your positive qualities. Changing the way you think and working on those you need to improve will go a long way towards promoting a positive self-image. When you can pat(拍) yourself on the back, you’ll know you’re well on your way. Good luck!

B. To make your life successful.
C. To understand your own world.
D. To change the way you think.

A. How to prepare for your success.
B. How to face challenges in your life.
C. How to build a positive self-image.

Much of the energy that comes from the Sun never reaches the Earth’s surface. It is either reflected or absorbed by the gases in the upper atmosphere. Of the energy that reaches the lower atmosphere, 30% is reflected by clouds or the Earth’s surface. The remaining 70% warms the surface of the planet, causes water to evaporate, and provides energy for the water cycle and weather. Only a tiny part, approximately 0.023%, is actually used by green plants to produce food.
Many gases found in the atmosphere actually reflect heat energy escaping from the Earth’s surface back to the Earth. These gases act like the glass of a greenhouse in that they allow energy from the Sun to enter but prevent energy from leaving. They are therefore called greenhouse gases.
When sunlight strikes an object, some of the energy is absorbed and some is reflected. The amount reflected depends on the surface. For example, you’ve probably noticed how bright snow is when sunlight falls on it. Snow reflects most of the energy from the Sun, so it contributes to the low temperatures of winter. Dark-coloured surfaces, such as dark soil or forest, absorb more energy and help warm the surrounding air.
59. According to the passage, the root cause for weather changes on the Earth is ______.
A. the atmosphere surrounding the Earth
B. water from oceans and lakes
C. energy from the Sun
D. greenhouse gases in the sky
60. Only a small part of the Sun’s energy reaches the Earth’s surface because most of it _______________.
A. absorbed by the clouds in the lower atmosphere
B. reflected by the gases in the upper atmosphere
C. lost in the upper and lower atmosphere
D. used to evaporate water from the oceans and lakes
61. We learn from the passage that _______________.
A. all living things on the Earth depend on the Sun for their food
B. a forest looks dark in winter because it absorbs solar energy
C. only 0.023% of the energy from the Sun is made use of on the Earth
D. greenhouse gases allow heat energy to escape from the Earth’s surface
