By adopting a few simple techniques, parents who read to their children can greatly increase their children's language development. It is surprising but true. How parents talk to their children makes a big difference in the children's language development. If a parent encourages the child to actively respond to what the parent is reading, the child's language skills increase. A study was done with 30 three-year-old children and their parents. Half of the children participated in the experimental study; the otherhalf acted as the control group. In the experimental group, the parents were given a two-hour training session in which they were taught to ask open-ended questions rather than yes-or-no questions. For example, the parent should ask, "What is the doggie doing?" rather than "Is the doggie running away?" The parents in the experimental group were also instructed in how to help children find answers, how to suggest alternative possibilities and how to praise correct answers. At the beginning of the study, the children did not differ in measures of language development, but at the end of one month, the children in the experimental group showed 5.5 months ahead of the control group on a test of verbal expression and vocabulary. Nine months later, the children in the experimental group still showed an advance of 6 months over the children in the control group. 1. Which of the following can be inferred from the passage? A. Children who talk a lot are more intelligent. B. Parents who listen to their children can teach them more. C. Active children should read more and be given more attention. D. Verbal ability can easily be developed with proper methods. 2. What does "it" in line 2 can most probably be replaced by? A. Parents increasing children's language development B. Reading techniques being simple C. Parents reading to children D. Children's intelligence development 3. According to the author, which of the following questions is the best type to ask children about? A. Do you see the elephant? B. Is the elephant in the cage? C. What animals do you like? D. Shall we go to the zoo? 4. The difference between the control group and the experimental group was __________. A. the training that parents received B. the age of the children C. tile books that were read D. the number of the children 5. The best conclusion we can draw from the passage is that __________. A. parents should be trained to read to their children B. the more children read, the more intelligent they will become C. children's language skills increase when they are required to respond actively D. children who read actively seem six months older 帮忙解答一下，尤其能详细说下为什么最好。谢谢了
