Only two animals have entered the human household otherwise than as prisoners and become domesticated by other means than those of enforce servitude (束缚): the dog and the cat. Two things they have in common, namely, that both belong to the order of carnivores and both serve man in their capacity of hunters. In all other characteristics, above all in the manner of their association with man, they are as different as the night from the day. There is no domestic animal which has so rapidly altered its whole way of living, indeed its whole sphere of interests, that has become domestic in so true a sense as the dog; and there is no animal that, in the course of its century-old association with man, has altered so little as the cat. There is some truth in the assertion that the cat, with the exception of a few luxury breeds, such as Angoras, Persians and Siamese, is no domestic animal but a completely wild being. Maintaining its full independence, it has taken up its abode in the house and outhouses of man, for the simple reason that there are more mice there than elsewhere. The whole charm of the dog lies in the depth of the friendship and the strength of the spiritual ties with which he has bound himself to man, but the appeal of the cat lies in the very fact that she has formed no close bond with him, that she has the uncompromising independence of a tiger or a leopard while she is hunting in his stables and barns; that she still remains mysterious and remote when she is rubbing herself gently against the leg of her mistress or purring contentedly in front of the fire. I should no more like to be without a cat in my home than to be without the dog that trots behind me in field or street. Since my earliest youth I have always had dogs and cats about me. Business-like friends have advised me to write a dog-book and a cat-book separately, because dog-lovers dislike cats and cat-lovers frequently abhor dogs. But I consider it the finest test of genuine love and understanding of animals if a person has sympathies for both these creatures, and can appreciate in each its own special virtue. The appeal of the dog chiefly lies in its________.

In 1997, Kelley Scanlon, an epidemiologist, and her colleagues at the Centers for Disease Control received a call from Georgia health authorities with disturbing news. The parents of two infants had weaned their babies onto soy-and-rice-based milk substitutes, even though both can lack crucial nutrients found in fortified cow’’s milk and formula. As a result, the children were suffering from diseases that had all but disappeared in the United States: rickets (a severe deficiency of vitamin D) and kwashiorkor (protein deficiency). Without intervention, the infants could have grown up with bone or brain damage. Soy and rice drinks continue to grow in popularity because they’’re safe for adults and low in fat and cholesterol. But what some parents don’’t know is that the drinks, if given to infants as primary sources of nutrition, can lead to health problems associated with kids in Third World countries. While national numbers aren’’t available, doctors are reporting nutrition-deficiency cases — many linked to rice and soy milk — in otherwise healthy kids in the United States and Canada. Recently, the medical journal Pediatrics published an article citing two cases of "severe nutritional deficiency" linked to the beverages. The problems associated with rice and soy milk are most pressing in kids younger than 2 because they don’’t eat as wide a variety of food as older toddlers. (The American Academy of Pediatrics says infants younger than 6 months should get 210mg of calcium, mostly from breast milk, each day.) "We’’re only seeing the tip of the iceberg," says Scanlon of the CDC, who estimates that up to 80 percent of kids with milder cases of malnutrition may not be properly diagnosed. "[Parents] don’’t recognize that something that’’s called milk is not necessarily infant formula," adds Bob Issenman, chief of pediatric gastroenterology and nutrition at McMaster Children’’s Hospital in Hamilton, Ontario. Rice milk is chiefly made from brown rice and sweetener. The drink is often fortified with calcium, iron and B vitamins, but it’’s usually low in protein. Without enough protein, says Albert Yan, babies’’ skin becomes like "flaky paint" and their hair, lacking enough melanin, gets lighter. More seriously, they develop tissue swelling (edema) and their bodies fail to produce crucial immune factors. Soy milk, by comparison, contains about the same amount of protein as cow’’s milk, but not all brands are fortified with vitamin D. Breast-feeding moms are sometimes advised to use supplements, too, since breast milk doesn’’t contain much D. And vegan moms’’ milk can be low in another vitamin, B12. The good news is the nutritional problems are often reversible. Talk to your pediatrician and check your child’’s diet against the American Academy of Pediatrics’’ recommendations (aap.org). After all, it’’s your job to do their body good. Among the following,________is not the symptom of lack in protein.
根据下面短文回答下列问题。 Tom and Tim are twins. They look the same. They study in the same class, and Miss Li is their Chinese teacher. Tom works hard at his lessons, but Tim likes nothing but playing.

根据下面短文回答下列问题。 The car was invented just a century ago. You may know all kinds of car names, but many people don’t know who the inventor of the first car was. The first car was invented not by a German, but by an American. His name was Henry Ford. Henry was born in a poor family. He was the eldest of six children. When he was a boy he became interested in fixing watches and machines. When he was twelve years old, his mother died. Soon he had to work in a machine shop for two dollars and fifty cents a week. In the evenings he repaired watches for another dollar a week. The hard life made him strong and able. At that time, there was another interest in the life of the young Ford. He dreamed of making a machine that could run without horses, so he named it "horseless carriage". He overcame a lot of difficulties and in April 1893, the "horseless carriage" was finally finished: it was the first car. Later Henry Ford founded the Ford Motor Company. He was really the first inventor of the car in the world. How many dollars did young Ford earn(赚) every week
