Each week, this program explains the many meanings of English expressions．Today's expressions include a very important word－“heart”．We will try to“get to the heart of the matter”to better understand the most important thing about words and their stories．So“take heart．”Have no fear about learning new expressions．Besides, popular English words can be fun．There is no need for a“heavy heart．”Such feelings of sadness would only“break my heart,”or make me feel unhappy and hopeless．
Now, let us suppose you and I were speaking freely about something private．We would be having a“heart to heart”discussion．I might speak from“the bottom of my heart,”or say things honestly and truthfully．I might even“open up my heart”to you and tell you a secret．I would speak with“all my heart”．
When a person shares her feelings freely and openly like this, you might say she“wears her heart on her sleeve”．Her emotions are not protected．
If we had an honest discussion, both of us would know that the other person's“heart is in the right place．”For example, I would know that you are a“kind-hearted”and well-meaning person．And, if you are a very good person, I would even say that you have“a heart of gold．”However, you might have a“change of heart”based on what I tell you．Our discussion might cause you to change the way you feel about something．
But, let us suppose you get angry over what I tell you．Or worse, you feel no sympathy or understanding for me or my situation．If this happens, I might think that you have a“heart of stone．”And, if you say something to make me frightened or worried, my“heart might stand still”．

A device that stops drivers from falling asleep at fine wheel is about to undergo testing at Department of Transport laboratories and could go on sale within 12 months．
The system, called Driver Alert, aims to reduce deadly road accidents by 20％－40％ that are caused by tiredness．Airline pilots can also use it to reduce the 30％ of all pilot-error accidents that are related to fatigue．
Driver Alert is based on a computerized wristband．The device, worn by drivers or pilots, gives out a sound about every four minutes during a car journey．After each sound the driver must respond by．squeezing the steering wheel(方向盘)．A sensor in the wristband detects this pressing action and measures the time between the sound, and the driver’s response．
Tiredness is directly related to a driver’s response time．Usually, a watchful driver would take about 400 milliseconds to respond but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy．
In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest．If the driver’s response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible．
The device has been delivered to the department’s 1aboatories for testing．If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year．

Most animals have little connection with animals of a different kind, unless they hunt them for food．Sometimes, however, two kinds of animals come together in a partnership which does good to both of them．You may have noticed some birds sitting on the backs of sheep．This is not because they want a ride, but because they find easy food in the parasites(寄生虫)on sheep．The sheep allow the birds to do so because they remove the cause of discomfort．So although they can manage without each other, they do better together．
Sometimes an animal has a plant partner．This relationship develops until the two partners cannot manage without each other．This is so in the coral(珊瑚)of the sea．In their skins they have tiny plants which act as " dustmen", taking some of the waste products from the coral and giving in return oxygen which the animal needs to breathe．If the plants are killed, or are even prevented from light so that they cannot live normally, the corals will die．
