The most important part of dog-care is cleanliness. Not only does the dog have to be kept clean, but his environment should also be clean. The bed he sleeps in can be made with anything like a rug or a dog mattress. Proper feeding is also important for your dog's health. A dog should be fed in the same place and on a regular schedule. If your dog refuses to eat, don't force him. Remove his food and don't feed him again until his next regular feeding. Food should never be left before a dog for more than 30 minutes. One important thing that many dog owners forget is exercise for the dog. Vigorous exercise helps build strength and keeps the dog healthy. A regular walk at a fixed time of the day is enough to help a smaller dog live a healthier end happier life.

But if you observe the three main points covered above, your dog will give you a great amount of pleasure. (23) A．Until he eats it. B．All day. C．At lease 30 minutes. D．No more than 30 minutes.

It is not customary to telephone someone very early in the morning in the USA. If someone is called very early in the morning，while he is shaving or having breakfast，the time of the call indicates great importance of the matter which requires immediate attention of the person called. The same implication is attached to telephone calls made after 11:00 p.m. at night. If someone receives a call during sleeping hours，he assumes it’s an urgency of life or death. The time chosen for the call communicates its importance. Time plays a very important role in our social life as you can imagine. In the USA an invitation should be sent to the guests in advance because guests usually believe that they are not highly regarded if the invitation to a dinner party is extended only three or four days before the party date. But it is not always necessarily true of the case all over the world. In some other countries，it may be taken stupid to make an appointment too far in advance because plans made for a date more than a week away tend to be forgotten. The concept of time varies in different regions of the world. Thus，misunderstandings are sometimes inevitable between men of different cultural backgrounds that treat time differently. Promptness is valued highly in America，for example. A lack of promptness is regarded as being impolite or not being fully responsible. In the US it would be incredible to keep a business partner or a guest waiting for an hour，and it would be too impolite and unacceptable by their social etiquettes. A person who is 5 minutes late is expected to give some words of explanation to the people waiting，though he might not complete his sentence. 16. What is the main idea of this passage？ A.
