【題目】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?

A. The development of Wi-Fi.

B. Various ways to get access to the Internet.

C. The influences of the Internet on our life.

D. The convenience of using cellphones.

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

A. disadvantages B. functions

C. qualities D. benefits

【3】What 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.

【4】What 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.

During her sixty-year career performing, Lena Horne entertained people with her beauty and rich, emotional voice. She used her fame to fight social injustices toward African-Americans.

Lena Horne was born in New York. At sixteen, Lena became a dancer at the famous club in New York City in 1933. After taking voice lessons, she soon became a singer. In 1940, Lena Horne became the first African-American to perform with an all-white jazz hand. After performing at a club in Hollywood, California, she caught the attention of filmmakers.
