2 . In his latest Twitter shake-up, Elon Musk has decided to temporarily control how many tweets users can read each day.
On Saturday, Musk announced the daily limit, with some accounts restricted to 300 posts. Musk said verified users would be able to read 6,000 posts per day, while unverified and newly created unverified accounts would only be able to read either 600 or 300 posts per day.

The Internet’s carbon footprint is as bad as air travel. While it is difficult to measure precisely, estimates place it at over two percent of global greenhouse gas emissions(排放)—the same as the air travel.
Information may appear to spread around the world unseen to our eyes, but it actually passes through enormous data centers placed strategically about the globe, which store, organize and deliver everyone’s data. These centers are extremely energy intensive. In the EU, they consume close to three percent of its total energy usage and also require lots of water to prevent their computers from overheating. In the US, about a fifth of data centers draw water from already stressed water sources.
A typical spam email(垃圾邮件)emits around 0.03g of CO2 emissions, though longer messages read on a laptop can go all the way up to 26g. Now multiply that by 333 billion(roughly the number of emails that get sent every day in 2022). That puts all those work emails into perspective. One study found if every British adult sent one less “thank you” email a day, it would save 16, 433 tons of carbon a year. It even predicted that the ICT industry could account for up to a fifth of the world’s energy consumption by 2025.
However, there are measures that we can take to reduce our digital carbon footprint. For instance, you can unsubscribe from marketing and other spam emails and only subscribe to newsletters that you still regularly read. Have regular data checks where you delete old contact lists and other documents that no longer have any use. Keep a clean inbox and delete emails you no longer need.

8 . Since springing up in 2008, Chinese SNS websites have been growing rapidly. While building perfect and complete platforms, SNS websites have been attracting a greatly increasing number of users as well as enormous advertisers’ attention.
The birth of SNS websites brought us a new concept of socializing online using one’s real identity. Furthermore, the popularity of SNS websites has made real-identity online interaction (相互作用) a daily routine for almost all the Internet users. Blogs, photos, virtual gifts, games and other SNS applications have increased real emotional interaction among Internet users.
Obviously, real-identity online communication has become a major competitive advantage of SNS websites. Many experts conclude that SNS websites have created a network of real socializing and have solved people’s daily problems in communication. Therefore, solving real life issues and keeping friendly interpersonal relationship are the critical factors that ensure the survival and growth of SNS websites. Data report shows that Renren. com has helped 63 users find a friend every second during the whole year of 2009 and created a billion friendships.
In addition, celebrities, institutions and organizations have gradually become members of SNS websites. Information sharing becomes more diverse, and the emergence (出现) of social games satisfies users’ need for interactive entertainment.
By gaining users in 2009, the SNS profit model has gradually grown clearer. According to the CNNIC annual report, 80% of SNS profit comes from Internet advertisement, 15% from VAS and another 5% from other sources.
As the real marketing value of SNS was discovered by more businesses, many successful partnerships emerged. Advertising professions believe that the foundational qualities of SNS include participation, interaction, self-expression, and emotional communication. These qualities are the basis of SNS marketing activities, and they will promote the birth of more marketing models.

10 . As data and identity theft becomes more and more common, the market is growing for biometric (生物测量) technologies—like fingerprint scans—to keep others out of private e-spaces. At present, these technologies are still expensive, though.
Researchers from Georgia Tech say that they have come up with a low-cost device (装置) that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence (节奏) with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user’s typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people’s identities, and by extension, whether they should be given access to the computer it’s connected to—regardless of whether someone gets the password right.
It also doesn’t require a new type of technology that people aren’t already familiar with. Everybody uses a keyboard and everybody types differently.
In a study describing the technology, the researchers had 100 volunteers type the word “touch” four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.
1. What makes the invention of the smart keyboard possible?| A．Computers are much easier to operate. |
| B．Fingerprint scanning techniques develop fast. |
| C．Typing patterns vary from person to person. |
| D．Data security measures are guaranteed. |
| A．It’ll be environment-friendly. |
| B．It’ll reach consumers soon. |
| C．It’ll be made of plastics. |
| D．It’ll help speed up typing. |
