In middle infancy, the baby concentrates on practicing a great many speech sounds. It loves to imitate actions and examine interesting objects. At about seven months, it begins to crawl, a skill that it masters at the end of middle infancy.
In late infancy, the baby takes an interest in games, songs, and even books. Progress toward walking moves through standing, balancing, bouncing in place, and walking with others. As soon as the baby walks well alone, it has passed from infancy into the active toddler (蹒跚学步) stage.
What is the main subject of this reading passage?
A.Growth in early infancy.
B.The active toddler.
C.How a baby learns to walk.
D.The developmental stages of infancy.
In America, you can achieve if you are prepared. You can soar(高飞)as far as your knowledge, drive and social skills will take you. The hitch is that although most of our children are born with incredible potential, far too many of them never see their promises fulfilled because their brains dont get enough stimulation(刺激)early in life. Jon Fine, CEO and president of United Way of King County, showed slides(幻灯片)of two brains during a speech Friday. One showed the brain of a child who received lots of stimulation, and the other the brain of a neglected child. There was a marked difference in the development of the temporal lobe(颞叶), which meant the child who hadnt had rich experiences in his or her early childhood would have trouble processing information. High-quality early education is the surest way to reduce the high school dropout rate because children start learning the moment they enter the world. It could keep more people out of prison and help grow the talent well need to rebuild our economy, mend our environment and write brilliant music. Think about something as simple as vocabulary. How do children acquire the kind of deep and broad repository(储存)of words and language skills that are the foundation of success in school and in life? Obviously, since you need it to succeed in school, waiting until you are in school to learn isnt the best option. Kids learn at home from their parents, and parents arent equally prepared to teach. Kids who arrive at school behind rarely catch up.
Which is the best title of this passage?
A.The Importance of Early Education.
B.The Equal Chance in America.
C.Family Education in America.
D.The Cause of the High-school Dropout Rate.
Heavy alcohol consumption also affects the body's usage of other drugs and medications. The dosages required by excessive drinkers may differ from those required by normal or non-drinkers. Serious consequences can be incurred unless the prescribing physician is aware of the patient's drinking habits.
Sudden death may result from excessive drinking. It might occur when the individual has ingested such a large amount of alcohol that the brain center controlling breathing and heart action is adversely affected, or when taking some other drugs, particularly sleep preparations along with alcohol. Death, as a result of excessive drinking, can come during an automobile accident since half of all fatal traffic accidents involve the use of alcohol. Many self-inflicted deaths, as well as homicides, involve the use of alcohol.
It is important to remember that alcohol is a drug that is potentially addictive. Once the user is hooked on alcohol, withdrawal symptoms occur when it is not sufficiently available to body cells. At the onset of developing alcohol addiction, these symptoms may be relatively mild and include hand tremors, anxiety, nausea, and sweating. As dependency increases, so does the severity of the withdrawal syndrome and the need for medical assistance to cope with it.
In 1956 the American Medical Association supported the growing acceptance of alcoholism as an illness, falling under the treatment jurisdiction of the medical profession. Since then, the medical resources for problems of acute and chronic intoxication have increased and improved.
