A
The government may control prices when there is a problem such as rapidly increasing rents or a rise in the cost of living.When the government controls prices，there is no longer a normal relationship between the price of a product and the quantity consumers will buy.Government controls may help in an emergency.However，some economists believe that controls can have negative effects over a long period of time.
In cities with rent control，the city government sets the maximum rent that a landlord can charge for an apartment.Supporters of rent control argue that it protects people who are living in apartments.Their rent cannot increase；therefore，they are not in danger of losing their homes.However，the critics say that after a long time，rent control may have negative effects.Landlords know that they cannot increase their profits.Therefore，they invest in other businesses where they can increase their profits.They do not invest in new buildings which would also be rent-controlled.As a result，new apartments are not built.Many people who need apartments cannot find any.According to the critics，the end result of rent control is a shortage of apartments in the city.
Some theorists argue that the minimum wage law can cause problems in the same way.The federal government sets the minimum that an employer must pay workers.The minimum helps people who generally look for unskilled，low paying jobs.However，if the minimum is high，employers may hire fewer workers.They will replace workers with machinery.The price，which is the wage that employers want decreases.Thus，critics claim，an increase in the minimum wage may cause unemployment.Some poor people may find themselves without jobs instead of with jobs at the minimum wage.
Supporters of the minimum wage say that it helps people keep their dignity.Because of the law，workers cannot sell their services for less than the minimum. Furthermore，employers cannot force workers to accept jobs at unfair wages.
Economic theory predicts the results of economic decisions such as decisions about farm production，rent control，and the minimum wage.The predictions may be correct only if“other things are equal”．Economists do not agree on some of the predictions.They also do not agree on the value of different decisions.Some economists support a particular decision while others criticize it.Economists do agree，however，that there are no simple answers to economic questions.
1．There is the possibility that setting maximum rent may______.
A．cause a shortage of apartments
B．worry those who rent apartments as homes
C．increase the profits of landlords
D．encourage landlords to invest in building new apartments
2．The problem of unemployment will arise______.
A．if the minimum wage is set too high
B．if the minimum wage is set too low
C．if the workers are unskilled
D．if the maximum wage is set too high
3．The passage tells us______.
A．the relationship between supply and demand
B．the possible results of government controls
C．the necessity of government controls
D．the urgency of getting rid of government controls
4．The attitude of the author to price controls is______.
A．subjectiveB．indifferent
C．objective
D．supportive

Yoga has been practiced for centuries.Many people see yoga as a stretching exercise designed to provide the physical body with strength and flexibility.But yoga is far more than that.Developed from Indian culture，yoga was intended to bring together the mind and the body.The word yoga itself means“unite”，and the movements involved in yoga are created to unite one to their inner self，providing greater clarity，self-awareness and peace.
Yoga can be performed individually or in groups.The movements of yoga are precise and require practice to master.A yoga teacher，or a guru，is a great guide to introduce you to the many different positions and disciplines of yoga.Initially，a person may only be able to accomplish the most basic yoga movements.But，in time，they will develop improved flexibility and strength and will be able to incorporate more intense movements and positions.Many physical sickness can be cured with yoga.By holding the positions and controlling breathing，a person is able to lower their blood pressure and heart rate.This is especially effective for people with heart conditions.Because yoga increases blood circulation，it is also very helpful in reducing painful varicose veins(静脉曲张)．The stretching required from yoga has been shown to help people who suffer from back，neck or hip pain.
Yoga therapy is widely recognised as an effective complementary treatment for many mental health issues.The controlled breathing and intense focus required in yoga enable someone suffering from depression to redirect their attention away from negative and harmful thoughts.It provides a sense of peace and can reduce anxious feelings that often accompany depression.People who have the symptoms of post-traumatic(受伤后的)stress disorder(PTSD)have been known to experience the benefits of yoga as well.In several studies，veterans and others with PTSD have seen a significant reduction in symptoms after practicing yoga for several weeks.Many people who engage in yoga discover the root of problems that have been plaguing(折磨)them for years.
Yoga is practiced in many different forms.It is recommended that a person should work with a licensed yoga therapist when they begin their path of yoga.
5．The main idea of the text is______.
A．the physical and psychological benefits of yoga
B．some scientific studies about yoga
C．where yoga comes and goes
D．the various reasons for practising yoga
6．Which of the following can best describe the meaning of the word yoga itself?
A．Yoga provides strength and treatment to the body.
B．Yoga can help people who suffer from back，neck or hip pain.
C．Movements involved in yoga bring together the mind and the body.
D．Yoga has been developed from Indian culture and is good for people’s mood.
7．How can yoga help people with mental problems?
A．It increases the blood circulation.
B．It involves uniting the mind and body.
C．It can redirect their attention away from harmful thoughts.
D．It can incorporate more intense movements and positions.
8．What does the author recommend?

二、任务型读写
阅读下面短文，根据所读内容在表格中的空白处填入恰当的单词。注意：每个空格只填一个单词。
If you are lost in the mountains，stay calm in the face of darkness，loneliness，and the unknown.It will greatly increase your chances of survival.Many people think that preparing necessary equipment and knowing how to use it are very
important，but actually eighty percent of mountain survival is your reaction to fear.
FIND A HIDING PLACE
Unnecessary labor will make you sweat and make you cold.Find a hiding place around you before trying to start your own construction.If you are in a snow-covered area，you may be able to dig a cave in deep snow for protection from the wind.You should try to hide yourself in the middle of the mountain if possible.Stay out of the valleys—cold air falls，and the valley floor can be the coldest area on the mountain.
SIGNAL RESCUERS FOR HELP
The best time to signal rescuers is during the day.Signal for help from the highest point possible—it will be easier for rescuers to see you，and any sound you make will travel farther.If you take a box of matches and a space blanket(a special blanket for traveling)，build three smoky fires and put your blanket—gold side facing out—on the ground.
DO NOT WALK AWAY
It will make finding you more difficult if you have gone off in a different direction，as search teams will be trying to follow your path.Searchers often end up finding a car with no one in it.
If you get frostbite，do not re-warm the affected area until you’re out of danger.You can walk on frostbitten feet，but once you warm the area and can feel the pain，you will not want to walk anywhere.Try to protect the frostbitten area and keep it dry until you are rescued.
