There is no doubt that television has become the most powerful tool for communication around the world, providing entertainment, news and information programs for people of all ages.

During the early part of the twentieth century, television was simply a dream or a vision in the minds of science fiction writers. In 1923, a student in Germany, Manfred von Ardenne, was the first person to produce a television image.

In the 1950s, television really became the \"main event\" in family entertainment, and over the next few decades, many people would spend hours watching their favourite programs on their television sets. Today, television is a major industry in many countries, employing many thousands of people and creating billions of dollars in revenue.

The introduction of cable television in the 1980s really changed the way people watched television. With a choice of channels and no advertising, cable television provided viewers with better quality programs and alternative choices.

The growth of satellite technology in the past few years has also opened up even more possibilities for the television industry, from the introduction of pay-per-view services to the ability to transmit programs live from almost anywhere in the world.

Questions:

(1) What was television like during the early twentieth century?

(2) Why did cable television change the way people watched television?

(3) What is satellite technology?

　The first world cup sailing competition, held in 1930, was won by the Dutch sailor, Auke Sonnema. Today, sailors from all over the world compete in a range of races from small dinghies to huge racing yachts.

　In recent years, the America’s Cup has become the most prestigious event in world sailing. This competition was established by the Royal Yacht Squadron in 1851, when a revolutionary new boat from America called America sailed across the Atlantic to take on the best that Britain had to offer. Today, the America’s Cup is held every four years and features high-tech racing boats with wing-shaped sails that reach speeds of up to 60 miles per hour.

　In contrast, the Olympic sailing regatta features classic races such as the Laser Class, in which competitors race identical designs of single-handed boats over a number of rounds. Team racing and match racing are also part of Olympic sailing.

Questions:

1. When was the first world cup sailing competition held and who won it?

2. Which competition has become the most prestigious event in world sailing?

3. What are some of the races in the Olympic sailing regatta?

For the ten years that I have taught eighth grade English, I have noticed that the summer assignment has become ever more important for incoming students. Although testing continues to be a priority and expectations for performance remain high, the summer assignment helps to level the playing field for all of my students.

Summer assignment benefits include:

1. Boosting Vocabulary: Students who read or participate in a summer reading program improve their vocabulary skills.

2. Reducing \"Summer Slide\": Research shows that if students are not engaged in learning during the summer, they can forget up to 1-2 months of important instruction. However, summer assignments can help to prevent and even reverse this tendency.

3. Preparing for the Future: High school and college both have summer reading programs that help students to prepare for the upcoming coursework.

Questions:

1. What is one purpose of summer assignments?

2. What is summer slide?

3. What do summer reading programs help students with?

1、某个操作系统每个进程的主内存地址都按照独立的地址空间进行映射，不同进程之间的地址空间互相隔离，这种操作系统被称为（ ）操作系统。

A. 内存共享

B. 随机存取

C. 互斥

D. 虚拟内存

答案：C

解析：A、B、D 都是修辞手法造句，语言生动生趣，而C所述乱升乱降，石萼之间不是严格对称，有些难以描述其高峰和落差，因此这个句子不是偏转落红的特点。

（3）2018年上海市高中学业水平考试公共基础科目

1、下列程序中，输出的结果是（）

unsigned long z;

void f(unsigned long *p, unsigned long *q)

{

*p += 2;

*q += z;

z += 2;

printf(\"%ld %ld %ldn\", *p, *q, z);

}

int main()

{

unsigned long x = 5, y = 7;

z = 10;

f(&x, &y);

f(&x, &y);

printf(\"%ld %ld %ldn\", x, y, z);

return 0;

}

A. 7 20 12 9 22 14 11 24 16 16 24 20

B. 7 20 12 7 29 18 9 29 20 7 29 20

C. 7 20 12 7 29 18 9 29 20 9 29 22

D. 7 20 12 7 29 18 9 29 20 11 29 24

答案：B

解析：首先，f 函数的作用是*p +=2，*q += z, z += 2，printf(\"%ld %ld %ldn\", *p, *q, z)；最后，main 函数的作用是调用两次 f 函数，然后输出 x, y 和 z 的值。根据这些信息，可以得出答案B。
