Taking this medicine, if ________, will certainly do damage to your health, as the doctor advises.
A．continuingB．continuedC．keepingD．to keep
B

試題分析:考查動詞辨析及省略。continute 持續(xù)，繼續(xù)；keep 保持，保存；從語義判斷此處是指持續(xù)服用藥物，所以排除C，D選項。從結(jié)構(gòu)可知此處是狀語從句的省略原句應(yīng)該是if it is continued，所以B選項正確。句意：正如醫(yī)生建議的，如果持續(xù)服用這種藥物，你的健康將肯定會受到損害。

There are two types of people in the world. Although they have equal degree of health and wealth and other comfort of life, one becomes happy while the other becomes unhappy. This difference comes from the different ways in which they consider things, persons, events, and the resulting effects upon their minds.
People who are to be happy fix their attention on the convenience of things, the pleasant parts of a conversation, the well prepared dishes, for example. They enjoy all the cheerful things. Those who are to be unhappy think and speak only of the opposite things. So, they’re always dissatisfied. They cannot feel the pleasure of society, they hurt other people, and they make themselves unpopular everywhere. Their intention of criticizing and being disliked is perhaps taken up by imitation, but it gradually grows into a bad habit as time goes on.
Though being unhappy is most probably an act of imagination, it has serious results in life, for it brings on deep sorrow and bad luck. The unhappy ones hurt many people; nobody will love them, and nobody will treat them with basic politeness and respect. When they need some advantages in social position or fortune, no one will wish them success.
In order to help the unhappy ones, it is strongly suggested that they should change their bad habit and be pleased with what is pleasing, without worrying needlessly about themselves and the others. If they do it, it will be good for both themselves and the others, and bright life will definitely smile at them some day.

Not long ago, people thought babies were notable to learn things until they were five or six months old．Yet doctors in the United States say babies begin learning on their first day of life．
Scientists note that babies are strongly influenced by their environment．They say a baby will smile if her mother does something the baby likes．A baby learns to get the best care possible by smiling to please her mother or other caregiver．This is how babies learn to connect and communicate with other human beings．
One study shows that babies can learn before they are born．The researchers placed a tape recorder on the stomach of a pregnant woman．Then, they played a recording of a short story．On the day the baby was born, the researchers attempted to find if he knew the sounds of the story repeated while in his mother．They did this by placing a device in the mouth of the newborn baby．
The baby would hear the story if he moved his mouth one way．If the baby moved his mouth the other way, he would hear a different story．The researchers say the baby clearly liked the story he heard before he was born．They say the baby would move his mouth so he could hear the story again and again． 
Another study shows how mothers can strongly influence social development and language skills in their children．
Researchers studied the children from the age of one month to three years．The researchers attempted to measure the sensitivity of the mothers．The women were considered sensitive if they supported their children’s activities and did not interfere unnecessarily．They tested the children for thinking and language development when they were three years old．Also, the researchers observed the women for signs of depression．
The children of depressed women did not do as well in tests as the children of women who did not suffer from depression．The children of depressed women did poorly in tests of language skills and understanding what they hear．
These children also were less cooperative and had more problems dealing with other people．The researchers noted that the sensitivity of the mothers was important to the intelligence development of their children．Children did better when their mothers were caring, even when they suffered from depression．
小題1:What does the experiment in which newborn babies heard the stories prove?
（no more than 5 words）
小題2:In the passage, what factors are mentioned that influence intelligence development in babies?

Researchers found that women are overcome by a burning desire to share gossip（流言蜚語）as soon as they hear it. They will typically tell the secret to at least one other person in 47 hours. Depending on who the gossip is about, their boyfriend, husband, best friend or mother is most likely to be the recipients（接受者）of the information.
The study of 3,000 women aged between 18 and 65 also found that. four out of ten admitted they were unable to keep a secret—no matter how personal or secret the news was. It was also found that alcohol usually gives us a helping hand to let out secrets—with more than half admitting a glass or two of wine could get them to dish the dirt.
Michael Cox, UK Director of Wines of Chile, said, “It’s official that women can’t keep secrets. We are really eager to find out with this survey how many secrets people are told. What we don’t count on（指望）is how quickly these are passed on by those we trust. No matter how precious the piece of information is, it often comes out within 48 hours.”
Three quarters say they are able to keep quiet about a secret, and 83 percent consider themselves 100 percent reliable within each group of friends. Yet, four in ten admit to gossiping to a close friend from another friendship group. Nearly half（45 percent）disclose secrets just for the weight to be lifted from their shoulders. More than four in ten think it is acceptable to share a friend’s secret with someone who doesn’t know him or her.
Private issues, true cost of purchases and affairs emerged top of the secret-keeping list, with girls most likely to share a secret chatting face-to-face, on the phone or via a text message. Fortunately, over a quarter（27 percent）said they forgot what they were told the following day.
小題1:Please explain the underlined words “dish the dirt” in English. （No more than 5 words.）
小題2:What makes women more likely pass on gossip? （No more than 3 word.）
小題3:What kinds of secrets are women most interested in? （No more than 10 words.）
小題4:Why do about half women tell secrets to others? （No more than 10 words.）
