3 On university campuses in Europe, mass socialist or communist movements gave rise to increasingly violent clashes between the establishment and the college students, with their new and passionate commitment to freedom and justice. Much of the protest was about the Vietnam War. But in France, the students of the Sorbonne in Paris managed to form an alliance with the trade unions and to launch a general strike, which ultimately brought about the resignation of President de Gaulle.
Text
In descending order these are: quality of courses, employability prospects, affordability, personal security issues, lifestyle, and accessibility. College has become a means to an end, an opportunity to increase one's chances on the employment market, and not an end in itself, which gives you the chance to imagine, just for a short while, that you can change the world.

Advantages
Telecommunication is now understood as a system consists of three elements: a transmitter（发射机，传送者） that takes information and converts（使转变） it to a signal; a transmission that carries the signal; and a receiver that receives the signal and converts it back into usable information. Some other telecommunication systems such as mobile telephones, computers in network act as both a transmitter and receiver or a transceiver.
Conclusion
Both advantages and disadvantages exist in using telecommunication tools frequently. The digital connection cannot replace the sense which felt by your eyes, face and mouth which carry more means, but we have to admit that telecommunication is necessary and essential to our daily life.

Average speeds is faster than most people's home broadband. As a result, there is an argument that it is no need to upgrade current communication system,because existing networks have already been able to meet the daily needs; and the research and development expenses for 5G will increase the consumers ’ burden.幻灯片6However, if we compare the wireless speed to the height in real life. From 2G to 5G, you can see them here. 2G is like a grasshopper,3G is like a border collie, and even 4G is just like a 5-story building. As the 5-srory building cannot meet our demand in real life, 4G will not meet ourcommunication demand in nest few years. We need khalifa tower, the 5G.幻灯片 7Why 5G is necessary?High speed and low latency10–100Gbps 4G’s 100–1000 times2–5msHuge capacityThe number of connected devices will reach 50 billionby 2020.To integrate existing systems seamlesslyWi-Fi(Wireless Fidelity), LTE (Long Term Evolution)and HSPA (High Speed Packet Access)Of cause, 5G can meet our demand. Because it canprovide the high speed with low latency. the rate of 10-100 Gigabitpersecond, it is 4G ’s 100-1000 times. And with its ultra low latency, only 2 to 5 millisecond, it can provide the excellent user experience.Second, Internationaltelecom organization points out that the number ofconnected devices will reach 50 billion by 2020. At that time, each person may have the smart glasses, the smart phone, the iPad, the laptop, and the smart watch. All of these need to the internet. With the limited bandwidth resource, current networks cannot accommodate so many intelligent terminals. And this is also a big challenge for 5G.Last but not least, 5G hasthe ability to integrate existing systemsseamlessly, including Wi-Fi (Wireless Fidelity), LTE and HSPA (High Speed Packet Access). In this way it can maximize the use of existing resources and increase redundancy insurance.幻灯片8What could 5G do?Real-time short messages for emergencyNext, we move on to what 5G could do, in another word, how 5G could change our lives. Thanks to the low latency and huge capacity, 5G would allow, for example, real-time short messages to be sent to citizens ’ smart phones immediately when the earthquake or other natural disasters are detected. Citizens can use theseseconds to turn off all open flames to prevent fire disaster, and to open an exit (doors or windows) in case of deformation caused by earthquakes.幻灯片9And it can also be used to the high speed rail wayemergency system. With the low latency ‘s help, the train can brake after 2millisecond when theearthquake was detected.幻灯片 10What could 5G do?Real-time short messages for emergencyInternet of thingsairports, sensors around usMoreover, the internet of things is another benefit from 5G. The 5G ’s goal is everything could connect to the internet. Thistechnology could help the airports.幻灯片 11Today, 10 percent of all flights cancellations and delays are caused by unscheduled maintenance events. Something goes wrong unexpectedly. This results in six billion pounds in costs for the airline industry globally every year.幻灯片12not to mention the impact on all of us: stress, inconvenience, missed meetings as we sithelplessly in an airport terminal.幻灯片 13So how can the internet of things help here? 5G can develop a preventivemaintenance system which can be installed on any aircraft. It'sself-learning and able to predict issues that a human operator would miss. The aircraft, while inflight, will communicate with technicians on the ground. By the time it lands, they will already know if anything needs to beserviced. A system like this can prevent over 60 thousand delays and cancellations every year inEurope , helping seven million passengers get to their destinations on time.幻灯片 14What could 5G do?Real-time short messages for emergencyInternet of thingsairports, sensors around us connecting to theinternetHowever, the 5G, theinternet of things, can not only benefit the bigcompany, but also the common person. A professor of MIT, bring the sensors to his house. The sensors connected to internet can feel people around them, and then open the recorder and camera to record his son ’s life. His son, after the firstbirthday, would say "gaga" to mean water. And over the next half-year, he slowly learned the rightpronunciation of "water." So we're going to look through half a year in about 40 seconds. No video here, so you can focus on the sound, a new kind of journey: gaga to water. Finally, he succeed , didn ’t he? The sensors can record every time of us, so we can look back to find our happiness. Or do other useful things.幻灯片 15What could 5G do?Real-time short messages for emergencyInternet of thingsairports, sensors around us connecting to the internetCloud ComputingThe last point I want to present is cloud computing. 5G ’s download speed is much faster than current hard disks' speed. Which means traditional storage devices may lose their status in 5G time and would be replaced by the “Cloud ”.幻灯片16Q & ASo that is my presentation. Here is the q&a time, I would very appreciate to answer your questions.。
通信革命与现代高等教育英语作文
Communication Revolution and ModernHigher EducationIn the era of rapid technological advancement, the communication revolution has revolutionized the way we interact and exchange information. This revolution has had a profound impact on modern higher education, shaping the way students learn, teachers teach, and institutions operate.The advent of the internet and digital technologies has brought about a seismic shift in higher education. Online learning platforms have emerged, breaking the geographical barriers that once limited access to higher education. Students from all over the world can now access a wide range of courses and learning resources, enabling them to pursue their academic goals regardless of their location. This has opened up new opportunities for those who may have been unable to afford or access traditional higher education institutions.Moreover, the communication revolution has transformed the teaching-learning process. Interactive online classrooms and collaborative tools allow students to engagewith their peers and teachers in real-time, fostering a more dynamic and inclusive learning environment. Teachers can also utilize digital technologies to create engaging and innovative lesson plans, making learning more fun and effective.Furthermore, the communication revolution has had a significant impact on the operation of higher education institutions. Administrative tasks such as admissions, grading, and scheduling have become more efficient and streamlined through the use of digital tools and software. This has allowed institutions to focus more on improving the quality of education they provide, rather than being bogged down by administrative burdens.However, while the communication revolution has brought about numerous benefits to modern higher education, it has also presented some challenges. The proliferation of online learning platforms has led to a rise in the number of unqualified or fraudulent institutions, making it crucial for students to exercise caution when choosing a learning provider. Additionally, the digital divide remains a significant issue, as many students still lack access tothe necessary technologies and infrastructure to fully participate in online learning.In conclusion, the communication revolution has been a catalyst for positive changes in modern higher education. It has broken down barriers, expanded access, and transformed the teaching-learning process. However, to ensure that these changes are sustainable and beneficial for all, it is crucial for institutions, teachers, and students to embrace the revolution responsibly and address the challenges it poses.**通信革命与现代高等教育**在科技飞速发展的时代，通信革命彻底改变了我们交流和交换信息的方式。
