C The day before yesterday, I had the pleasure of visiting with Deputy Superintendent Pedro Martinez, Principal Neddy Alvarez and her staff at Western High School, located in the Clark County School District, in Las Vegas. The school undertook a prehensive effort to pletely transform the culture of the school and added a motivated group of talented teachers. Western altered（改變） the school day to add opportunities for students to get additional credits toward graduation and created smaller learning groups. As part of these prehensive changes, the school’s leadership also focused on four main reforms to transform their school. First, improvements started with the change in the relationship between the school and students to create a caring atmosphere at the school. Using the “Capturing Kids’ Hearts” strategies, school leadership and teachers began building a trusting environment and students and families described seeing changes aimed at improving student outes and ensuring the success of every student. The school day was altered to add more options for students to obtain additional credits toward graduation. Students and teachers were grouped into “houses,” so that smaller groups of teachers and counselors(輔導員 )could create oneonone relationships with students. Teachers and counselors said that the altered school day provides time to address student’s individual concerns and develop individualized learning plans to put every student on a path to graduation. The school also made changes to encourage parents to support school and encourage real dialogues between parents and the teachers and leaders at Western. Funded in part through the United Way, the school created a family engagement center to get parents more involved in their children’s education, particularly parents of English language learners. Parents like Ally Gaona and Martha Mendez told me that they had a voice and the tools to engage in their children’s lea rning and that they recognize that the main responsibility for their children’s learning must rest with the parents. Parents were passionate about these positive changes and said that these changes signaled to the entire munity that the school was serious about family engagement. 28． What is the main purpose of the passage?

History is full of cases where dreams have been a pathway to creativity and discovery. A striking example is provided by Dr. Otto Loewi, a pharmacologist (藥理學家 ) and winner of a Nobel Prize. Loewi had spent years studying the chemical transmission of nerve impulses (脈搏 ). A tremendous breakthrough in his research came when he dreamed of an experiment three nights in a row. The first two nights he woke up and wrote down the experiment quickly and untidily on paper. But the next morning, he couldn’t tell what the notes meant. On the third night, he got up after having the dream. This time, instead of making notes he went straight to his laboratory and performed the important experiment. Loewi later said that if the experiment had occurred to him while awake he would have rejected it. Loewi’s experiment gives some insight into using dreams to produce creative solutions. Nervous feelings are reduced during dreaming, which may be especially useful in solving problems that require a fresh point of view. Being able to take advantage of dreams for solving is improved if you “set” yourself before retiring. Before you go to bed, try to think intently about a problem you wish to solve. Bury yourself in the problem by stating it clearly and reviewing all relevant information. Then use the suggestions listed in the previous section to catch your dreams. Although this method is not guaranteed to produce a novel solution or a new insight, it is certain to be an adventure. About half of a group of college students using the method for a week recalled a dream that helped them solve a personal problem. 32. The main idea of this passage is that _________. A. very little is really known about the meaning of dreams B. it is possible to“catch”one’s dreams by planning before going to sleep C. dreams can be useful in producing creative solutions to one’s problems D. Loewi’s experiment helped in the study of transmission of nerve impulses 33. The first paragraph is mainly anized by _________. A. classifying types of expe
