5G networks have been considered as one big thing for this century. They allow people to get faster services. Downloading information takes only seconds, instead of minutes.

But no true 5G phones are able to be used now. It won’t work with 5G until such services are built. Users will need an adapter to bring in 5G signals. There’s completely no need for users to worry about the safety of 5G signals.

Where will we probably see 5G first? The answer is in our living rooms. The speeds, about 20 times faster than the standard home Internet connection, are very likely to do wonders in our living rooms. Many users are tired of spending $100 or more monthly in booking cable(有线的) TV. They no more choose cable TV and begin to use streaming(在线播放) services connected to their broadband(宽带) service instead.

Besides faster access, connectivity might get a little cheaper in future for users only if a complete 5G network is set up. However, the cost of programs and apps will go up. Meanwhile, users are in great need of ordering more monthly services. Comparatively speaking, users are likely to pay more for 5G services.

So far now, it’s mainly used at home.

1.People can feel 5G’s advantage directly by its _____.

A. surprising speed B. comparatively low cost

C. powerful function D. convenient Internet connection

2.Why are 5G phones not widely used today?

A. Because services are limited. B. Because special equipment isn’t built yet.

C. Because 5G signals are not strong enough. D. Because the safety of 5G signals is not for sure.

3.What will the writer probably write about next?

A. 5G’s role. B. 5G’s history. C. 5G’s influence. D. 5G’s development.

4.Where does this passage probably come from?

A. A story book. B. A science fiction. C. A popular science book. D. A research report.

Imagine a classroom missing the one thing that has long been considered a necessary part to reading and writing? No paper，no books，no test paper．Nor are there any pencils or pens which always seem to run out of ink at the important moment．

A "paperless classroom" is what more and more schools are trying to achieve．Students don't do any handwriting in this class． Instead，they use hand-sized or specially-designed computers．The teacher downloads information from Internet libraries and sends them to every student's personal computer．

Having computers also means that students can use the Web．They can look up information on any subject they're studying from math to social science．High school teacher Judy Herrell in Florida，US，described how her class used the Web to learn about what's going on in the world．

"We could touch every side of the country through different sites from the forest to refugee（难民） camps，" she said．"Using a book that's three or four years old is impossible " And exams can go online too．At a high school in Tennessee，US，students take tests on their own computers．The teacher records the grades on the network for everyone to see and then copies them to his own grade book on the Internet．

A paperless classroom is a big step towards reducing the waste of paper．High school teacher Stephanie Sorrell in Kentucky，US，said she used to give about900 pieces of paper each week to each student．
