3.阅读理解①Would you like to have a brother or a sister? Years ago this might have sounded impossible to many. But since several years ago, with the end of China's "one-child policy(政策)", this could actually happen now. All Chinese couples are allowed to have two children. It means that many Chinese children may have siblings(兄弟姐妹) in the future.②What would it be like growing up with a brother or a sister? Having a sibling can stop children from bad feelings, according to Laura Padilla-Walker, a teacher from Brigham Young University, US. "Siblings give children something that parents can't," she said. You may not feel lonely at home any more because there is someone to play with you. You can also share secrets with him or her.③"But children with siblings also have to learn to control(控制)their feelings," said Padilla-Walker. You need to share things with them, such as attention from parents, toys, the bathroom and the TV. There are also unpleasant situations such as competition, name-calling and even hair-pulling.④Even the birth order of siblings could matter too. US psychologist Kevin Leman said that birth order decides the way parents treat their children, thus causing different personalities between siblings.⑤Kevin Leman explained that parents are usually more strict with their first child. So firstborns may be perfect because parents set high goals(目标) for them. They usually act well and hope to succeed. When the couple has a second child, they have fewer rules. So late-born children are usually more creative. They also love attention. It is said that many of them also have a good sense of humor.(1)The underlined word "this" in Paragraph 1 refers to(指) ______.A. one-child policyB. having a brother or a sisterC. the end of "one-child policy"D. being allowed to have more than two children (2)In Paragraph 2, the writer mainly tells us ______.A. the advantages of having a siblingB. how to look after a siblingC. how to get on well with a siblingD. the secrets of having a sibling(3)According to Kevin Leman, ______.A. late-born children are usually successful at schoolB. having a sibling can stop children from bad feelingsC. parents are usually more strict with their first-born childD. children with siblings have to learn to control their feelings(4)Which of the following best shows the structure(结构) of the passage?A. B.C. D.【答案】(1)B(2)A(3)C(4)D【解析】【分析】文章大意:中国开放二胎,家里有2个小孩,会使得孩子不感到孤独,父母对待孩子的方式不一样,第一胎较为严格。
