Feel tired lately？ Has a doctor said he cant find anything wrong with you？ Perhaps he has 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 sub-health （亚健康）.

Sub-health， also called the third state or gray state， is explained as a borderline state between health and disease.

According to the survey by the National Health Organization， over 45 percent of sub-healthy 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 include a lack of energy， depression， slow reactions， insomnia， anger， and poor memory. Other symptoms include shortness of breath， sweating and aching in the waist and legs.

The key to preventing and recovering from sub-health， 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 （营养的） elements—vitamins and other elements that are important to the body.

Nutrition 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 （消化道）. They also say that a balanced diet is very helpful in avoiding sub-health.

1. It may be easy for middle-aged people to get sub-healthy because ___ .

A. they begin to get older

B. they have used up their energy

C. they have lost their living hopes

D. they have more pressure in life and work

In the past， people who graduated from college felt proud of their academic achievements and confident that their degree （学位） would help them to find a good job.

However， in the past four years the job market has changed greatly. This years college graduates are facing one of the worst job markets. For example， Ryan Stewart， a graduate of San Jose State University， got a degree in religious studies， but he has not got any job offers. He points out that many people already working are getting laid off （失业） and dont have jobs， so its even harder for new college graduates to find jobs.

Four years ago， the future looked bright for his class of 2009. There were many high-tech （“dotcom”） job opportunities， graduates received many job offers， and they were able to get jobs with high salaries and benefits such as health insurance and paid vacations. However， “Times have changed. Its a new market”， according to an officer of the university.

The officer says students who do find jobs started preparing two years ago. They worked during summer vacations， they have had several short-time jobs， and they majored in fields that are still paying well， such as accounting or nursing.

Even teaching is not a safe profession now. Ryan Stewart wanted to be a teacher， but instead he will probably go back to school in order to become a college teacher. He thinks college teaching could be a good job even in a bad economy.

In conclusion， these days a college degree does not lead to a good job with a high salary. Some students can only hope that the value of their degree will increase in the future.

A. It was a proof of their professional skills.

D. It would guarantee their quick lift in their position.

6. Why has Ryan Stewart not got any job offer？

B. He wants to find a job with very high salary.

C. He has not received a degree in the university.

D. The job market has changed greatly since 2009.

7. Why does Ryan Stewart want to be a college teacher？

A. Teaching jobs are well-paid.

B. He majored in teaching in the university.

C. College teaching is less challenging than high-tech jobs.

D. College teaching career wont be influenced by economy.

8. What can be concluded from the passage？

A. Graduates must prepare early to find jobs.

B. New college graduates today cant find jobs.

C. A college degree can still lead to a good job.

D. The value of a college degree has reduced now.

Just like humans， birds also rely on sound to communicate. However， they do not have a “language” in the true sense of the word and instead produce a variety of sounds to express different emotions.

Often， birds recognize their mates （or young） by sound rather than sight. Hungry young birds use begging calls to let their mothers know it is feeding time. Alarm calls， flight calls and warning calls are other sounds made frequently by adults.

A new study shows that songbirds rehearse （排演） their songs even in their sleep. The activity in the brain of the birds when asleep is similar to the brain activity when the birds were awake and singing. The team used tiny recording devices to measure the activity of individual brain cells in four songbirds both when they were singing and when they were asleep.

Obiviously this kind of bird stores a song after hearing it， and then rehearses it later in its sleep. Scientists now believe the birds “dream of songs and tunes” to help them master the fine art of singing and that sleep plays a key role in the learning process！

Many songbirds learn to sing by listening to adult birds of the same species. However， if separated from the adults， the young birds develop sounds which are hard to understand instead of normal song patterns. Researchers carried out an experiment in which a male bullfinch （红腹灰雀） was raised by a female canary （金丝雀）. The bullfinch soon learned the canarys song and when it was later mated to a female bullfinch， Mr Bullfinch taught his children the canarys songs.

Last year， a British survey of Londons songbirds showed that the citys birds are losing their tunes. Birds could hardly hear one another， over the traffic noise； as a result， instead of copying the sweet notes of the adults， young birds were copying the sounds they heard most often， namely car horns and beeping cellphones！

1. How do birds recognize their mates？ （no more than 5 words）

2. What kind of calls might a hungry young bird make？ （no more than 2 words）

3. What does the new study show about the songbird in their sleep？ （no more than 6 words）

4. Who could young birds learn from if separated from the adults？ （no more than 9 words）

5. What causes the citys birds to lose their tunes？ （no more than 3 words）
