Feel tired lately? Has a doctor said he can’t find anything wrong with you? Perhaps he sent you to a hospital, but all the advanced equipment there shows that there is nothing wrong with you．
Then, consider this: you might be in a state of subhealth (亚健康)．
Subhealth, also called the third state or gray state, is explained as a borderline state between health and disease．
According to the investigation by the National Health Organization, over 45 percent of subhealthy people are middle-aged or elderly．The percentage is even higher among people who work in management positions as well as students around exam-week．
Symptoms(征兆)include a lack of energy, depression(压抑),slow reactions, insomnia(失眠),agitation, and poor memory．Other symptoms include shortness of breath, sweating and aching in the waist and legs．
The key to preventing and recovering from subhealth, according to some medical experts, is to form good living habits, alternate work and rest, exercise regularly, and take part in open air activities．
As for meals, people are advised to eat less salt and sugar．They should also eat more fresh vegetables, fruits, fish because they are rich in nutritional elements…vitamins and trace elements …vitamins and trace elements…that are important to the body．
Nutrition(营养)experts point out that it is not good to eat too much at one meal because it may cause unhealthy changes in the digestive tract(消化系统)．They also say that a balanced diet is very helpful in avoiding subhealth． According to this passage, which of the following is true?
| A．When you are in a state of sub-health, you should stay at home and keep silent. |
| B．When you are in a state of sub-health, you should go to see a doctor and buy some medicine. |
| C．When you are in a state of sub-health, you should have yourself examined in foreign countries. |
| D．When you are in a state of sub-health, you should find out the reasons and relax yourself. |
It may be easy for middle-aged people to get sub-healthy because _________.
| A．they have used up their energy |
| B．they have lost their living hopes |
| C．they have more pressure in life and work |
| D．they begin to get older |
The key to preventing you from falling into a state of sub-health is that you should ________.
| A．work hard |
| B．sleep more |
| C．form good living habits |
| D．take more medicine |
As for food, experts suggest that ________.
| A．we should never eat meat |

| C．we should eat less than usual |
| D．we should have meals without salt and sugar |
Did you know that there are actually people who have paid for a flight to the moon? In the future, there will be a lot more opportunities to travel to faraway places than now… perhaps even as far as the moon. As people adventure further and further away and as planes, trains, cars, and rocket ships become faster, is it safer to have these vehicles controlled by humans or by computers?
While many flights by plane are controlled automatically by machines, most people today wouldn’t let their car drive itself. That’s because currently the autopilot function on your car can only keep it on the same course you are travelling on. It won’t turn the car right or left. It won’t stop if an animal jumps in the way. However, cars today can sense when something is too close and warn the driver with flashing lights and alarms. Many cars also have GPS（global positioning systems） that tell drivers which road to take and when to turn. These systems, unlike human drivers, never get lost. In the future, it is easy to believe that your car will be better able to drive itself with the aid of computers that can determine the position of your car and the speed it should travel at.
In addition to computers being ‘smarter’ than people regarding the best way to go or knowing how close another vehicle is, computers don’t get sick, tired, or angry. This means they won’t make the same mistakes that people make when they are not having a good day. While responding with emotion is a good thing when choosing the best way to deal with a friend’s personal problem, it may not be such a good thing when deciding what to do at the wheel of a fast-moving vehicle.
So what are the disadvantages of autopilot systems? Maybe one disadvantage is that a small computer problem could cause a serious accident. It could also be argued that in unexpected situations, computers might not be able to respond appropriately; some decisions require human emotions. Another problem might be that if everything were controlled by computers or robots, people wouldn’t have any jobs. What is the best title for the passage?
| A．The Development of Autopilot |
| B．Technology of Future Travel |
| C．A New Driving System |
| D．Computerized Cars |
Which of the following is the disadvantage of an autopilot system?
| A． It won’t make the same mistakes as people do. |
| B． It can point out the best route for the driver. |
| C． It might not respond properly to unexpected situations. |
| D．It does not have human emotions to influence its function. |
If some falling rocks roll down toward your car, the autopilot on your car will_______.
| A．inform you of the danger |
| B．turn the car right or left |
| C．do nothing about it |
| D．stop the car |
What’s the author’s attitude towards the autopilot?
| A．Approving. | B．Objective. | C．Negative. | D．Doubtful. |
Most city parks are places where you can escape from big, ugly structures of metal and stone. The Manhattan High Line is different. Raised 25 feet above the ground, this massive metal structure once supported a rail line. The line opened in 1934 to bring trains directly into factories and warehouses. It was hardly used after the 1960s, and much of it was torn down. However, one section remained in an area of Manhattan called Chelsea. Chelsea was becoming more and more valuable as restaurants, art galleries and apartments were built, but the ugly railway structure remained as a dead weight. Everyone knew that at some time, it would have to be removed.
But the High Line was not destroyed. In fact, now the old rail line serves as one of the most peaceful places in the city. It holds an elevated park, with beautiful gardens, a sidewalk and great views of the city. The idea to change the rail line into a park came from Joshua David and Robert Hammond. In 1999, they attended a community meeting to decide the fate(命运) of the High Line. David and Hammond were the only people at the meeting interested in saving the structure for its historical significance. Later on, when they asked railway officials to take them up to look at the High Line, they saw a mile and a half of wild flowers growing in the middle of the city, and they realized that the High Line had potential to become a park. There was growing interest in improving urban centers, and so the project quickly won support and funds for construction were easily obtained.
The first section of the High Line opened in 2009 and immediately became popular with tourists and locals alike. Each part of the park has a different atmosphere. Some areas are like balconies (阳台)with wonderful city views. Where the rail line goes between buildings, trees are thickly planted. Other sections have wide walkways planted with wild flowers. Only the final section remains the way it has been for the last fifty years – a railway line overgrown with weeds.The underlined phrase “a dead weight” in Paragraph 1 means_____.
| A．something with potential to be better. |
| B．something with historical interest. |
| C．something which is a danger to people. |
| D．something useless which slows progress. |
According to Paragraph 2, David and Hammond wanted to save the High Line because they_____.
| A．thought it had historical value |
| B．wanted to reopen the train line |
| C．thought it would bring them money |
| D．were interested in improving the city |
From the last paragraph, we can learn that the park ______.
| A．is different in its design |
| B．is covered with trees |
| C．didn’t change at all |
| D．became a natural countryside |
Which of the following is NOT true about the High Line?
| A．It is situated above ground level. |
| B．Only part of the line remains. |
| C．It is now a popular park. |
| D．Trains still use the line. |
As a boy I was always small for my age. I was also five years younger than one of my brothers and seven years younger than the other. As a result I often felt left out when their friends came over to play. I was either too small or too young for whatever they were doing and they didn't want their younger brother listening in on their conversations either. More often than not I found myself outside playing alone and feeling forgotten.
I remember one spring afternoon feeling especially lonely as I sat in the yard behind our house. We lived miles from town and I rarely saw my own friends outside of school. I heard my brothers laughing from inside the house and felt a single tear coming down my cheek. At that moment I saw a large brown dog walking over to me. He looked happy and his tail was wagging as well. Even though he didn't know me he greeted me like a long lost friend, licking my chin and sitting beside me on the spring grass. It must have been at least an hour that I petted and talked to this four-legged angel. He let me pour out all my troubles and share my deepest thoughts before he kissed my cheek goodbye and ambled off either to Heaven or his home. I went back inside feeling happy, knowing that no matter what life may hold I was loved. Now over 40 years later I still remember that angel with a smile.
I believe that God sent him in that moment of sadness to remind me just how much he loved me. There is nothing more important than knowing we are loved. When we are loved, we will learn to love others. Learning to love helps us to understand ourselves and other people better.How did the writer feel when his brothers’ friends came?

The following are letters to the editor of a school newspaper
Dear editor,
I’d like to express my opinion about grades. Students should be allowed to study without worrying about grades. Fortunately, most educators are becoming aware of the fact that students have different interests and abilities. I understand that grades are useful, but grades often limit creativity. Competing for better grades causes many students to turn down opportunities to pursue music, dramatics and sports. Grades force an arbitrary(武断的) standard of success on everyone. I do not demand as some extremists do, that grades be removed immediately. However, I do believe that less emphasis should be placed on grades. I hope that someday grades will become optional at Village High School.
Magdalena Smith
Drama Club
Dear editor,
I’d like to say something about grades. Let’s face the facts about grades. Grades perform three basic functions. First, grades motivate students to work at their highest level of competence. Second, they act as a reward for hardworking students and as a punishment to students who do not work hard. Finally, grades are used as an effective standard by which to measure student achievement. Good grades help students to get jobs and to get into university. I've spoken with a number of students who have jobs, and most of them say that they were hired primarily on the basis of their grades. My grades helped me land a part-time job and will help me get into university next year. I think grades are extremely important at Village High School.

Many people believe the glare from snow causes snow-blindness. Yet, dark glasses or not , they find themselves suffering from headaches and watering eyes, and even snow-blindness, when exposed to several hours of “snow light”. The United States Army has now determined that glare from snow does not cause snow-blindness in troops in a snow-covered country. Rather, a man's eyes frequently find nothing to focus on in a broad expanse of barren (少植被的) snow-covered terrain (地形). So his gaze continually shifts and jumps back and forth over the entire landscape in search of something to look at. Finding nothing, hour after hour, the eyes never stop searching and the eyeballs become sore and the eye muscles ache. Nature eases this irritation by producing more fluid which covers the eyeball. The fluid covers the eyeball in increasing quantity until vision blurs (模糊), then is obscured (遮蔽), and the result is total, even though temporary, snow-blindness.
Experiments led the Army to a simple method of overcoming this problem. Scouts ahead of a main body of troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape. Even the scouts themselves throw lightweight, dark colored objects ahead on which they too can focus. The men following can then see something. Their gaze is arrested. Their eyes focus on a bush and having found something to see, stop scouring the snow-blanketed landscape. By focusing their attention on one object at a time, the men can cross the snow without becoming hopelessly snow-blind or lost. In this way the problem of crossing a solid white terrain is overcome.To prevent headaches, watering eyes and blindness caused by the glare from snow, dark
