After a long day at work, coming home is a breath of fresh air. Home is a comfortable place to sit back and relax. 1. Below are a number of things we can do to create a healthy home environment that will help to ease the workday stress and promote our physical and mental health.
Cleaning the house regularly is the first thing we should do. It may seem like a tiring thing to clean but there is a reason for doing so. We can remove dust by cleaning the house. Leaving layers of dust everywhere means that there is a build-up of dust. And where do these layers of dust go?2.
Making sure the rooms are full of sunlight is also important. We may not realize it but sunlight is an important part of our growth. We all know that sunlight promotes better working conditions. 3. Think about using a Parans system where sunlight does not reach. This technology gathers the sunlight by using solar panels. It can send out sunlight wherever we are.
4. Going green will help to remove toxins(毒素）in the air. They also give off oxygen, which can lower stress and improve our moods.
Along the lines of being green, it can also be vital to think about what things we are bringing into the house. Try to avoid specific plastics that are harmful to health. 5. They may contain poisonous chemicals that can be breathed in, or simple absorbed through the skin.
A. Into our lungs.
B. However, is it as healthy as it can be?
C. Is our home as comfortable as it used to be?
D. It is also a good idea to add more plants in our house.
E. The same thing applies to things like carpets and paint.
F. Besides, it can reduce both stress and high blood pressure.
G. It is acknowledges that a greener lifestyle is linked to better health.
NOT all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences in nightmares.
Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly expunge, the effect of painful memories.
In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are erased. They are not sure to what degree people’s memories are affected.
The research has caused a great deal of argument. Some think it is a bad idea, while others support it.
Supporters say it could lead to pills that prevent or treat soldiers’ troubling memories after war. They say that there are many people who suffer from terrible memories.
“Some memories can ruin people’s lives. They come back to you when you don’t want to have them in a daydream or nightmare. They usually come with very painful emotions.” Said Roger Pitman, a professor of psychiatry at Harvard Medical School. “This could relieve a lot of that suffering.”
But those who are against the research say that changing memories is very dangerous because memories give us our identity. They also help us all avoid the mistakes of the past.
“All of us can think of bad events in our lives that were horrible at the time but make us who we are. I’m not sure we want to wipe those memories out.” Said Rebecca Dresser, a medical ethicist.
1.What does the underlined word in paragraph 2 mean?
A.decrease B.release
C.reserve D.remove
2.The drug tested on people can ______.
A.cause the brain to fix memories
B.stop people remembering bad experiences

3.We can learn from the passage that ______.
A.all people don’t support the use of the pills
B.the pill will stop people’s bad experiences
C.taking the pill will do harm to people’s health
D.the pill has probably been produced in America
4.Which of the following does Rebecca Dresser agree with?
A.Some memories can ruin people’s lives.
B.People want to get rid of bad memories.
C.Experiencing bad events makes us different from others.
D.The pill will reduce people’s sufferings from bad memories.
The biggest safety threat facing airlines today may not be a terrorist with a gun, but the man with the portable computer in business class. In the last 15 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic interference. The source of this interference remains unconfirmed, but increasingly, experts are pointing the blame at portable electronic device such as portable computers, radio and cassette players and mobile telephones.
RTCA, an organization which advises the aviation (航空) industry, has recommended that all airlines ban such devices from being used during “critical” stages of flight, particularly take-off and landing. Some experts have gone further, calling for a total ban during all flights. Currently, rules on using these devices are left up to individual airlines. And although some airlines prohibit passengers from using such equipment during take-off and landing, most are reluctant to enforce a total ban, given that many passengers want to work during flights.
The difficulty is predicting how electromagnetic fields might affect an aircraft’s computers. Experts know that portable device emit radiation which affects those wavelengths which aircraft use for navigation and communication. But, because they have not been able to reproduce these effects in a laboratory, they have no way of knowing whether the interference might be dangerous or not.
The fact that aircraft may be vulnerable to interference raises the risk that terrorists may use radio systems in order to damage navigation equipment. As worrying, though, is the passenger who can’t hear the instructions to turn off his radio because the music’s too loud.

A.a new regulation for an airlines

D.They were suspected to have resulted from electromagnetic interference.
3.Few airlines want to impose a total ban on their passengers using electronic devices because ______.
A.they don’t believe there is such a danger as radio interference
B.the harmful effect of electromagnetic interference is yet to be proved
C.most passengers refuse to take a plane which bans the use of radio and cassette players
D.they have other effective safety measures to fall back on
4.It can be inferred from the passage that the author _____.
A.hasn’t expressed his own opinion on this problem
B.has overestimated the danger of electromagnetic interference
C.is in favor of prohibiting passengers’ use of electronic devices completely
