【题目】As long as you have broadband service in your home, you can turn on your desktop computer and connect to the Internet. If you have a wireless router, a device that spreads the broadband connection to other devices, you can set up a Wi-Fi network, which enables your cellphones and tablets go online too. And when you are outdoors where there is no Wi-Fi, such as in the park or at the beach, having 3G service allows you to stay connected.

It seems that lots of us have Internet coverage everywhere we go. So why have mobile companies around the world lately been so enthusiastic about a new term, 4G”? First, you need to know that the letter : “G” stands for “generation”. Even if you have no idea what 4G is, at least you can figure out that it is a step up from 3G since it’s the latest generation of mobile Internet service.

Unlike broadband, mobile Internet uses the same signal towers that provide voice service to your cellphone, which means wherever you can make phone calls with your cellphone you also have an Internet connection.

But mobile connections have their defects: they don’t carry as much information as broadband does, making opening websites and downloading music slower than they are on a Wi-Fi connection. This is why mobile connections have been constantly upgraded since the first generation was launched back in the 1980s.

According to BBC, 4G is five to seven times faster than current 3G network speeds, almost as fast as home broadband. Because of this, 4G is widely suited for services like video downloading, mapping, online shopping and even video conferencing.

To achieve the high speeds, network companies have to spend a lot of money on building new signal towers, which will eventually lead to a higher phone bill if you switch to 4G,, and you will also have to get a new phone with 4G capacity.

【1】What is paragraph 1 mainly about?

B. Various ways to get access to the Internet.

C. The influences of the Internet on our life.

D. The convenience of using cellphones.

2The underlined word “defects” in Paragraph4 probably means_______.

A. disadvantages B. functions

3What is the weakness of 3G compared with 4G?

A. Its voice is not as clear as 4G.

B. It can’t satisfy the users’ basic needs.

C. Its network speeds are much slower.

D. It has much less popularity than 4G.

4What does the author think of 4G service?

A. Its service is worth the price.

B. There is no need to develop it.

C. It takes time to be widely used.

D. It provides good service at a higher price.

【题目】I don’t ever want to talk about being a woman scientist again. There was a time in my life when people asked constantly for stories about what it’s like to work in a field dominated by men. I was never very good at telling those stories because truthfully I never found them interesting. What I do find interesting is the origin of the universe, the shape of space-time and the nature of black holes.

At 19, when I began studying astrophysics, it did not bother me in the least to be the only woman in the classroom. But while earning my Ph.D. at MIT and then as a post-doctor doing space research, the issue started to bother me. My every achievement—jobs, research papers, awards—was viewed through the lens of gender (性别) politics. So were my failures. Sometimes, when I was pushed into an argument on left brain versus (相对于) right brain, or nature versus nurture (培育), I would instantly fight fiercely on my behalf and all womankind.

Then one day a few years ago, out of my mouth came a sentence that would eventually become my reply to any and all provocations(挑衅): I don’t talk about that anymore. It took me 10 years to get back the confidence I had at 19 and to realize that I didn’t want to deal with gender issues. Why should curing sexism be yet another terrible burden on every female scientist? After all, I don’t study sociology or political theory.

Today I research and teach at Barnard, a women’s college in New York City. Recently, someone asked me how many of the 45 students in my class were women. You cannot imagine my satisfaction at being able to answer, 45. I know some of my students worry how they will manage their scientific research and a desire for children. And I don’t dismiss those concerns. Still, I don’t tell them “war” stories. Instead, I have given them this: the visual of their physics professor heavily pregnant doing physics experiments. And in turn they have given me the image of 45 women driven by a love of science. And that’s a sight worth talking about.
