已知f(t),为求f(t0-at)则下列运算错误的是(其中t0,a为正数)________。

;A.f(-at)左移t0

B.f(-at)右移t0

C.f(at)左移t0

参考答案:ACD


温度单位摄氏度℃与华氏度°F的关系是()。

A.t(°F)=5/9t(℃)+32

B.t(°F)=9/5t(℃)+32

C.t(°F)=9/5t(℃)-32℉

D.t(°F)=5/9t(℃)-32


正确答案:B


已定义好有参函数f(m),其中形参m是整型量。下面调用该函数,传递实参为5,将返回的函数数值赋给变量t。以下正确的是______。

A.t=f(m)

B.t=Call f(m)

C.t=f(5)

D.t=Call f(5)


正确答案:C
解析:含参数的过程被调用时,主调过程中的调用式必须提供相应的实参(实际参数的简称),并通过实参向形参传递的方式完成过程调用。而Call方法并不能向变量赋值。

A.f(t)+F(t)=1

B.R(t)+F(t)=1

C.R(t)=tfudu

D.F(t)=0f(u)du


正确答案:BCD


已定义好有参函数f(m),其中形参m是整型量。下面调用该函数,传递实参为5,将返回的函数值赋值给变量t。以下正确的是( )。

A.t=f(m)

B.t=Call f(m)

C.t=f(5)

D.t=Call f(m)


正确答案:C

A二、判断题 (本题型共10题,每题2分,共20分。以下各题的叙述,正确的在题后的括号内写T,错误的写F)1. F 2. F 3. F 4. F 5. T 6. T 7.T 8. F 9. T 10. F三、简答题 (本题型共5题,每题4分,共20分) 1. It is complex. There are direct hearers, and indirect hearers. Each of the two is itself complex. Take indirect hearers for example. There are eavesdroppers, overhearers and so on.2People believe that personal names are sacred. The name is the person himself or herself. The abuse of the name is equal to the abuse of the person. So measures are often taken to protect it. In Chinese culture children sometimes are given petty names or cheap names for superstitious purposes.3. Yes, someone may be attacked by a stroke. It may cause some damage to that part of the brain where language functions are located. Thus the person will not be able to speak or speak properly.4. (The answers for the first part of the task vary from one examinee to another. Right answers must include (a) things in the physical or material world; (b) things in the symbolic world; (c) things in the symbolic world. The answers for the second part must include (a) speech and writing belong to the material world; (b) the abstract form of language belong to the symbolic world. )5. There are 5 advantages, a. speech communication can be done in darkness; b. it can be separated by barriers; c. hands can be free to do other things; d. immediate feedback can be provided; e. body language can be used to support speech.四、论述题 (本题共2题,共40分)1. What are the different dimensions of relations between people in the society? What is the one dimension important to Chinese but absent in some other cultures? Choose one dimension to give an example: 答案:a. familiarity :whether the people interacting are strangers, acquaintances, family members or relatives. b. emotional distance: whether the people interacting are intimate or detached, whether they are close or hostile.c. formality: formal or informald. In Chinese culture we make the important distinction of in-group or out-group: Chineseinsiders, foreignersoutsides; Family circle: family memberinsiders; everybody else is an outsiders.e. Examples: (any one, one point)2. In unit 3, there is a paragraph as follows: “when we say that in Chinese chess there are five “soldiers”, we must realize that they are abstract soldiers which an be materialized in any soldier substance. The abstract “soldiers” are made “soldiers” because they are dictating the way they are used in game. You may argue that we cannot say that the materials of which Chinese chess is made are not significant. For instance, wood chess pieces can be less expensive than stone ones. Or magnetic chess pieces can be hung on the wall so that an audience can watch players play. Your reasoning is sound, but is irrelevant to the point we talk about. Our question is what makes a “soldier” a solider in Chinese chess. Your objection is about the differences in chess material.” Discuss the ways in which words are like the chess pieces.答案:1) words are also abstract;2). They can be materialized in a cluster of sounds, or strokes, or letters;3) words become words, not because they are made of materials, but because they are used together with other words in communication; the physical sounds or strokes can be important to some people, e.g. calligraphers, but calligraphy has little to do with linguistics.

累积故障(失效)公式表示正确的是( )。

A.F(t)=P(T>t)

B.F(t)=P(T≥t)

C.F(t)=P(T≤t)

D.F(t)=P(T<t)


正确答案:C
解析:产品在规定条件下规定的时间内,不能完成规定功能的概率,也是时间的函数,一般用F(t)表示,F(t)称为累积故障分布函数,即:F(t)=P(T≤t)。


以下哪个不可能出现在and的操作真值表中()

A.F T F

B.T T T

C.T F T

D.F F F


正确答案:C


已定义好有参函数f(m),其中形参m是整型量。下面调用该函数,传递实参为5,将返回值赋给变量t。以下正确的是( )。

A.t=f(m)

B.t=Call f(m)

C.t=f(5)

D.t=Call f(5)


正确答案:C
解析:函数的调用形式为:函数名([实参>])。由于函数会返回一个值,因此可以将函数的返回值赋予某个变量,其形式为:变量;函数名([实参>])。所以,本题的正确答案为C。


● 针对程序段:IF( A||B||C )THEN W=W/X,对于(A,B,C)的取值,(57)测试用例能够满足MCDC(修正条件逻辑判定)的要求。

(57)

A.(F,T,T) (T,F,T) (T,F,F) (T,T,F)

B.(T,F,F) (T,T,F) (F,T,T) (F,F,F)

C.(T,F,F) (T,T,F) (F,T,T) (F,F,T)

D.(T,F,F) (F,T,F) (F,F,T) (F,F,F)


正确答案:D


累积故障(失效)公式表示正确的是( )。A. F(t) =P(T>t) B. F(t) =P(T≥t)
C. F(t)=P(T≤t) D. F(t)=P(T


答案:C
解析:
产品在规定条件下规定的时间内,不能完成规定功能的概率,也是时间的函数, 一般用F(t) 表示,F(t) 称为累积故障分布函数,即: F(t)=P(T≤t)。
