题目
单选题
The students in a certain physical education class are on either the basketball team or the tennis team, are on both these teams, or are not on either team. If 15 students are on the basketball team, 18 students are on the tennis team, 11 students are on both teams, and 14 students are not on either of these teams, how many students are in the class?
A

48

B

40

C

36

D

30

E

28

参考答案和解析
正确答案: D
解析:
The number of students on one but not both of the two teams is the sum of the number of students on the basketball team plus the number on the tennis team minus the number on both teams: 15+18-11 =22. Since 22 students are on the basketball or the tennis team and 14 students are not on either team, there are 22+14 or 36 students in the class.

Teaching procedure:
Step 1: Warming-up

2. Ask students a question: what are you reading recently? And ask some students to share with the whole class.
Step 2: Presentation
1. Review the knowledge about the past tense of verbs: write some verbs on the blackboard and ask students to change the verbs into their past tense.
2. Ask students to read the dialogue and pay attention to the background information about Mark Twain. Then ask students some questions: What’ Mark Twain’ real name? When did he born? When did he begin to work? And then invite some students to share the answers with the whole class and write down on the blackboard.
3. Then ask students when these things happened and then tell them the rule of past tense: Simple Past Tense refers to the actions or states happened at a certain moment in the past, or a certain period of time in the past. It is often used with temporal adverbial, such as yesterday, last week and so on.
4. Ask students to read the dialogue again and try to find other sentences which used the Simple Past Tense and share with class. Then tell students the rule of general and special interrogative sentences in the past tense: general interrogative sentences use auxiliary verbs (did) and special interrogative sentences use special interrogative words (what, when, how...).
Step 3: Practice
1. Ask student to role play the dialogue and ask two groups to show in class.
2. Play a game: magic box. There is a magic box which is full of all kind of verbs, ask students to choose one card and then make a sentence with it using the Simple Past Tense.

Text 2 For years,studies have found that first-generation college students—those who do not havea parent with a college degree—lag other students on a range of education achievement factors.Their grades are lower and their dropout rates are higher.But since such students are most likely to advance economically if they succeed in higher education,colleges and universities have pushed for decades to recruit more of them.This has created“a paradox”in that recruiting first-generation students,but then watching many of them fail,means that higher education has“continued to reproduce and widen,rather than close”an achievement gap based on social class,according to the depressing beginning of a paper forthcoming in the journalPsychological Science.But the article is actually quite optimistic,as it outlines a potential solution to this problem,suggesting that an approach(which involves a one-hour,next-to-no-cost program)can close 63 percent of the achievement gap(measured by such factors as grades)between first-generation and other students.The authors of the paper are from different universities,and their findings are based on a study involving 147 students(who completed the project)at an unnamed private university.First generation was defined as not having a parent with a four-year college degree.Most of the first-generation students(59.1 percent)were recipients of Pell Grants,a federal grant for undergraduates with financial need,while this was true only for 8.6 percent of the students with at least one parent with a four-year degree.Their thesis—that a relatively modest intervention could have a big impact—was based on the view that first-generation students may be most lacking not in potential but in practical knowledge about how to deal with the issues that face most college students.They cite past research by several authors to show that this is the gap that must be narrowed to close the achievement gap.Many first-generation students“struggle to navigate the middle-class culture of higher education,learn the‘rules of the game,’and take advantage of college resources,”they write.And this becomes more of a problem when colleges don’t talk about the class advantages and disadvantages of different groups of students.“Because US colleges and universities seldom acknowledge how social class can affect students’educational experiences,many first-generation students lack sight about why they are struggling and do not understand how students‘like them’can improve.”We may infer from the last paragraph that_____

A.universities often reject the culture of the middleclass
B.students are usually to blame for their lack of resources
C.social class greatly helps enrich educational experiences
D.colleges are partly res

答案:D
解析:
推理题【命题思路】这是一道封闭推理题。本题主要考查考生有效辨别段落核心信息,进行适度推理的能力。【直击答案】根据题干关键词“infer from the last paragraph”定位到最后一段。本题是段落推理题,可以通过寻找段落中心句的方式来解。本段共三句:第一句和第二句是并列关系,均提出“初代”学生中存在的与社会阶层有关的问题。第三句以一个“because”所引导的原因状语从句点明中心,明确该问题的来源是美国高校未承认社会阶层对学生教育经历的影响,说明高校应该为出现的问题担负部分责任。因此D项正确。【干扰排除】A项、B项、C项在此段并未提及,属于无中生有,故排除。

The study suggests that most first generation students____

解析:
推理题【命题思路】这是一道推理题。主要考查考生精准理解原文定位信息,查找相互关联,并进行适度推理和概括的能力。【直击答案】根据题干关键信息“most firstgeneration students”定位到第三段末句“Most of firstgeneration students were recipients of Pell Grants(佩尔奖学金),a federal grant for undergraduates with financial need”。此句重在说明“初代”大学生大都接受了经济资助。比对四个选项,确定此题最佳答案为C项,其中“in need of”对应原文的“with…need”,“financial support”对应“financial”相对应。【干扰排除】A项是无中生有,原文仅提及此研究是在一个“unnamed private university”进行,并不是指“初代”大学生;B项和D项也属无中生有,原文未提及,故排除。

Recruiting more first generation students has____

A.reduced their dropout rates
B.narrowed the achievement gap
C.missed its original purpose
D.depressed college students

答案:C
解析:
细节题【命题思路】这是一道细节题。主要考查考生准确理解题干,精准定位,并能正确划分和掌握定位信息的能力。【直击答案】根据题干关键词“recruiting more firstgeneration students”定位到第一段的第四句。But后内容为解题关键。本句指出在招录“初代”大学生时出现的困境及产生的不良结果,即“不断产生和扩大成就差距,而不是缩小差距”。由此证明背离了初衷。比对四个选项,确定最佳选项为C项。【干扰排除】A项与原文的“their dropout rates are higher”矛盾,属于反向干扰,故排除。B项也是反向干扰,与原文的“rather than close”矛盾。C项属于张冠李戴,原文中的depressing是用来修饰the paper,而非大学生,故排除。
