When I finished, they _1_ me to go out with them to have a good time. When I was at their _2_， I probably would have given in to that temptation (誘惑) and gone.

Anyone who has had either a brother, a sister or both will know a little bit about sibling_rivalry. Sibling rivalry does not necessarily stem from (源于) the desire to be the “favorite” among ones parents. In fact， sibling rivalry can also be attributed to a sort of natural petition that arises between people, especially those living close to one another.Already, childhood describes and shapes the development of the relationships between siblings. So that type of hostile relationship may not continue throughout the siblings lives. This observation is apparent in many sibling relationships, even my own. Yet, what can explain the change that happens?Perhaps, it has something to do with maturity (成熟). Maturity focuses on ones relationships, even those between siblings. Whether or not maturity directly acplishes the creation of friendly terms between siblings is not entirely clear, but it is apparent that maturity helps to explain why siblings take focus away from creating antagonism (對立) and instead direct it towards munity. If the old saying, “Blood is thicker than water”， is applied to sibling relationships, we find that genetic relationships can enhance social relationships.So, even if we want sibling relationships to be peaceful and loving, we cannot expect those friendly terms to exist always. What is important in this type of relationship is the concept of forgiveness. Forgiveness can heal any wound, and in the case of sibling relationships, it can be the path to a life of togetherness and solidarity (團(tuán)結(jié))Therefore, it is entirely true that we cannot pick and choose who is in our family. But, we can learn to live together peaceably despite our differences. This not only applies to sibling relationships, but to all relationships in general.語篇導(dǎo)讀：手足之爭不一定是來源于希望得到父母更多的愛，實(shí)際上還可能是出于一種人與人之間的自然競爭。本文作者對這一現(xiàn)象產(chǎn)生的原因及其發(fā)展和影響進(jìn)行了分析和解讀。1. The underlined phrase “sibling rivalry” in Paragraph 1 probably means _.A. siblings pete for more love from their parentsB. parents can hardly treat their children equallyC. people would like to live close to one anotherD. students work hard together at their lessons答案：A詞義猜測題。根據(jù)上下文(第一段第一句到第三句)的意思可知，sibling rivalry在此處指“手足之爭”，即兄弟姐妹們爭相得到父母更多的愛。2. Which of the following can lead to a peaceful and solid life?A. The concept of determination.B. The quality of forgiveness.C. The friendly relationships.D. The spirit of bravery.答案：B細(xì)節(jié)理解題。根據(jù)第四段最后一句可知，原諒對穩(wěn)固家庭關(guān)系很有幫助，有利于促進(jìn)家庭的和睦與團(tuán)結(jié)。3. If we want to build good relationships, we should _.A. try our best to choose outgoing siblingsB. be always ready to help each otherC. accept all the different personalitiesD. try to be quite different from others答案：C細(xì)節(jié)理解題。根據(jù)最后一段第二句可知，接受各自的不同個(gè)性是建立良好關(guān)系的關(guān)鍵。 . 短文改錯Dear Smith，Im delighted that you have accepted our invitation to speak at my school the next week.
