Long gone are the days of dial-up and waiting for your turn to use the computer. It’s easier than ever to connect to the Internet in the digital world today. 【1】

Wi-Fi is a wireless network that uses radio frequency signals to connect to the Internet or send messages between devices without wires. Everything from your phone and laptop to tablets and printers can use Wi-Fi, thanks to these waves. 【2】 Two years later, a group of companies formed the Wireless Ethernet Compatibility Alliance (WECA, now the Wi-Fi Alliance), a global non-profit organization created to promote the new Wi-Fi standard.

None of that history explains what Wi-Fi stands for, because the phrase doesn’t stand for anything. Wi-Fi is a trademarked term describing the device or technology based on the Institute of Electrical and Electronics Engineers (IEEE) wireless communication standard 802.11, according to the Wi-Fi Alliance.【3】 So the Wi-Fi Alliance hired the marketing company Interbrand to come up with a shorter name: Wi-Fi, according to one of the founding Alliance members.

【4】 The rumor that it stands for “Wireless Fidelity (无线保证)” is thanks to the Alliance. Some members didn’t understand the branding or marketing for Wi-Fi. They felt consumers would want an explanation for the name. So the Alliance agreed to include a tagline: The Standard for Wireless Fidelity. That’s why so many people assume Wi-Fi stands for wireless fidelity, but the tagline came after the name.【5】 Don’t add to the confusion and stop miss-associating these phrases by learning the real meaning behind these acronyms (缩略词).

A. That’s a mouthful.

B. This is mostly thanks to Wi-Fi.

C. The name caused a misconception about Wi-Fi.

D. There is some debate surrounding the question what Wi-Fi stands for.

E. In 1997, a committee of industry leaders approved a common Wi-Fi standard.

F. Several years ago, a common standard of Wi-Fi was set up by several companies.

G. Plus, the Alliance removed the tag, although the confusion it brought still lives on today.

A. He feels hopeless. B. He likes Coke very much. C. He was too busy to go shopping.

A. See a doctor. B. Watch a movie. C. Meet her brother.

A teahouse is a special house which primarily serves tea and other light refreshments(茶点). Its function varies widely【1】(depend)on the culture. In China, a teahouse is a place 【2】people gather to enjoy tea, chat and socialize. It【3】(consider) as a symbol of Chinese tea culture and people’s leisure lives.

Chinese teahouses enjoy a long-standing history. They developed from tea 【4】(stand) in the Western JIN Dynasty, took shape in the Tang Dynasty, developed 【5】(gradual) in the Song, Yuan, Ming and Qing Dynasties and became booming in modern times.

In the Song Dynasty, teahouses spread all over the cities and villages, at a rate comparable with that of restaurants. The owners preferred to decorate their teahouses 【6】paintings of celebrities or rare and precious plants 【7】(attract) customers. In the Ming and Qing Dynasties, the number of teahouses went beyond that of restaurants, gaining much 【8】 (wide) popularity and becoming more famous. Later, the acculturation(文化植入)of western culture forced traditional Chinese teahouses to take on【9】 new look.

Since reform and opening-up, with the rapid development of the economy and evident improvement of people’s living standards, teahouses【10】(flower) in China.

Roommate horror stories are pretty popular topics of conversation at school. Follow a few simple tips to ensure you’re not the awful roommate everyone’s talking about.

Respect each other

First and foremost, you need to respect your roommate.

【1】If your roommate is sleeping, keep the noise and light levels down. If your roommate is studying, don’t have loud conversations in the same room. If in doubt, ask yourself whether you would be annoyed if your roommate didn’t do the above things for you.

Keep it clean. 【2】Hair in the shower or bathrooms littered with magazines or dirty clothes. Respect means keeping your side of the room clean. And hopefully, if your roommate sees you keeping your side clean, they’ll be more likely to keep theirs clean.

Keep your hands off their stuff. 【3】If you really need to borrow something of theirs, always ask before you do. If they say no, don’t get angry. Some people just don’t like other people using their stuff.

Set basic rules

You and your roommate should establish some basic rules. For instance, I really don’t like it when people have phone conversations in the room while I am studying. 【4】I’d rather be writing my paper than listening to you tell your best friend about your weekend. So discuss that with your roommate. Make a compromise, but the tie should go to the person studying. Another example is to discuss cleaning duties. Dividing cleaning duties will make your room cleaner and it will help ease roommate tensions. 【5】

A. Be considerate.

B. Talk on the phone.

C. Don’t use your roommate’s items without asking.

D. I’m not good at doing several things at the same time.

E. I have heard many horror stories about dirty roommates.

F. Taking out the trash and tidying the room are just a few things to consider.

G. It is amazing how people don’t understand what it means to be considerate.

When picturing the future, there are quite a few things that we would love our cell phones to be able to do. Let’s take a look at the ones that are likely to be in the next generation of cell phones. Cell phones of the near future will be able to start and unlock cars, turn lights on and off in houses, make payments(付款), work as computers. This sounds too good to be true, right? Fortunately, this future is just over the horizon; you won’t wait too long. New technology for phones is being developed to realize eye scans(扫描)and fingerprint scans as new“unlock your phone”, so you needn’t worry about your information being stolen.

What do I want my phone to be able to do? I want it to be special. For example, I will shout to my phone across the room“Give me directions to the market”and it pulls up the directions and sends them to my printer. Is it possible? Yes. Maybe someday cell phones will be able to change into robots and walk our dogs and clean our houses too. Who knows? In the last 30 years we have gone from hardly knowing what a cell phone was to surfing the Internet with excellent cell phones.

It is hard to believe that technology is advancing as quickly as it is, with no end in sight. In 5 years the technology of today will be a thing of the past, and the world won’t look back one bit.

【1】We learn from the text that cell phones________in the future.

A. can do a number of jobs you want it to do

B. only do the work we once thought of

C. don’t look like today’s cell phones at all

D. can pay for whatever you want to buy

【2】The underlined phrase“over the horizon”in Paragraph 2 can be replaced by“________”.

A. arriving as time goes B. what people all hope

C. what we work hard for D. coming in a short time

【3】If one’s eye scan is done by his cell phone, ________.

A. his picture is kept in it forever B. his information won’t be lost

C. his cell phone only serves him D. his cell phone won’t be stolen

【4】What is special about your future cell phone?

A. It works as a robot does. B. You can speak loudly to it.

C. It can give you information. D. It can warn you out of danger.

Carbon capture isn’t new, but previous methods call for the gas to be compressed into liquid and then injected underground. Widespread usage of that technology has been locked by economic and environmental concerns due to possible leaks. Instead, in a study published in Nature Communications, the group details their sustainable and cost-effective plan for transforming CO2 into coal.

This new process involves a liquid metal catalyst( 催化剂 )that is efficient in conducting electricity. CO2 gas is dissolved in a container with some liquid. Once electricity charge is introduced, the CO2 begins to turn into solid pieces of carbon, which can be collected and stored.

What makes this particularly unique is that the entire process can occur at room temperature. Previous experiments have only shown a gas to solid conversion at extremely high temperature, which made it impossible on a large scale. Now, the researchers are hoping that their work will be used to create even further when it comes to carbon storage.

In an interesting side benefit, the solid carbon also works as an electrode( 焊 条 ), which opens up a world of possibilities. “A side benefit of the process is that the carbon can hold electrical charge, becoming a super battery, so it could potentially be used as a part in future vehicles,” explains Dr. Dorna Estrafilzadeh, a researcher. “The process also produces fuel as a by-product, which could also have industrial applications.”

【1】What can we know about the previous carbon capture methods?

A.People have to inject liquid to the gas.

B.The previous methods can be done easily.

C.The previous methods are not very popular.

D.People have widely accepted previous methods.

【2】What is the special part of the new method?

A.It needs electricity to make the process efficient.

B.It can be done in any kind of container.

C.It doesn’t need extreme temperature.

D.It can produce much solid carbon.

【3】What can we infer from the last paragraph?

A.The method will make fossil oil disappear.

B.The method will influence the future industry.

C.The method will make developed countries more powerful.

D.The method will be used to make new vehicles.

【4】What is the best title for the passage?

A.How to change carbon into CO2.

B.A new carbon capture technology.

C.A new technology to get useful carbon.

D.Australia makes the world cleaner than before.
