【简答题】
An idea that started in Seattle's public library has spread throughout America and beyond. The idea is simple: help to build a sense of community in a city by getting everyone to read the same book at the same time. In addition to encouraging reading as a pursuit (追求) to be enjoyed by all, the program allows strangers to communicate by discussing the book on the bus, as well as promoting reading as an experience to be shared in families and schools. The idea came from Seattle librarian Nancy Pearl who launched (发起)the 'If All of Seattle Read the Same Book ' project in 1998. Her original program used author visits, study guides and book discussion groups to bring people together with a book, but the idea has since expanded to many other American cities, and even to Hong Kong. In Chicago, the mayor appeared on television to announce the choice of To Kill a Mockingbird as the first book in the 'One Book, One Chicago' program. As a result, reading clubs and neighborhood groups sprang up around the city. Across the US, stories emerged of parents and children reading to each other at night and strangers chatting away on the bus about plot and character. The only problem arose in New York, where local readers could not decide on one book to represent the huge and diverse population. This may show that the idea works best in medium-sized cities or large towns, where a greater sense of unity(一致)can be achieved .Or it may show that New Yorkers rather missed the point, putting all their energy and passion into the choice of the book rather than discussion about a book itself. As Nancy points out, the level of success is not measured by how many people read a book, but by how many people are enriched by the process or have enjoyed speaking to someone with whom they would not otherwise have shared a word. 小题1:What is the purpose of the project launched by Nancy? A.To invite authors to guide readers. B.To encourage people to read and share. C.To involve people in community service. D.To promote the friendship between cities. 小题2:Why was it difficult for New Yorkers to carry out the project? A.They had little interest in reading. B.They were too busy to read a book. C.They came from many different backgrounds. D.They lacked support from the local government. 小题3:According to the passage, where would the project be more easily carried out? A.In large communities with little sense of unity B.In large cities where libraries are far from home C.In medium-sized cities with a large population D.In large towns where agreement can be quickly reached 小题4:The underlined words “shared a word” in Paragraph 5 probably mean . A.exchanged ideas with each other B.discussed the meaning of a word C.gained life experience D.used the same language 小题5:According to Nancy, the degree of success of the project is judged by . A.the careful selection of a proper book B.the growing popularity of the writers C.the number of people who benefit from reading D.the number of books that each person reads

【简答题】请编写一个函数fun(),它的功能是:比较两个字符串的长度,(不得调用C语言提供的求字符串长度的函数),函数返回较K的字符串。若两个字符串长度相等,则返回第1个字符串。 例如,输入beijing<CR>shanghai<CR>(<CR>为回车键),函数将返回shanghai。 注意:部分源程序给出如下。 请勿改动主函数main和其他函数中的任何内容,仅在函数fun的花括号中填入所编写的若干语句。 ...
【单选题】已知可逆反应:M(g)+N(g)?P(g)+Q(g);△H>0.在某温度下,反应物的起始浓度分别为:c(M)=1mol/L,c(N)=2.4mol/L,达到平衡时N的转化率为25%.下列说法正确的是(  )
A.
达到平衡后,M的转化率小于25%
B.
温度升高,M的体积分数增大
C.
相同条件下,增大N的浓度,反应正向进行,平衡常数增大
D.
相同条件下,若起始时c(M)=c(N),达到平衡后,M的转化率>25%

【简答题】如何解释多元线性回归系数的含义?如何度量回归方程拟合优度?拟合优度的好坏是否可作为回归方程优劣是重要标志?
【判断题】拟合优度是衡量模型对样本观测值的拟合程度。常用R方和修正的R方来度量。
A.
正确
B.
错误
【简答题】已知可逆反应:A(g)+B(g) C(g)+D(g)  ΔH<0。请回答下列问题: (1)在某温度下,反应物的起始浓度分别为:c(A)='1' mol/L,c(B)='2.4' mol/L,达到平衡时,A的转化率为60%,此时B的转化率为 。 (2)若反应温度降低,则B的转化率将 (填“增大”、“减小”或“不变”)。 (3)若反应温度不变,反应物的起始浓度分别为c(A)='4' mol·L -1 ...
【判断题】可决系数是一个回归直线与样本观测值拟合优劣程度的度量指标,其值越大,拟合优度越好,其值越小,拟合优度就越差。
A.
正确
B.
错误
