【題目】 The network technology in your mobile phone is the result of years of development in wireless communications. It is called 2G, 3G, 4G and now 5G. 5G networks have been treated as the next big thing for wireless users. They allow people to get __, with videos that will start to play immediately and information downloads that will take only seconds, instead of minutes.

But no true 5G phones are able to be used now. Motorola has produced publicly the first 5G smartphone, the Moto Z3. But the problem is that 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. But when to use 5G directly is the point.

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. Cord-cutting has become popular and common. Many users are tired of spending $100 or more monthly in booking cable (有線的)TV. They don't choose cable TV any more and begin to use streaming (在線播放) services connected to their broadband (寬帶)service instead. The U.S. communications company Verizon has developed home broadband for its 5G tests and has decided to work together with Apple TV. Another U.S. top communications company, AT&T, now is the No. 1 broadband provider in the United States, tested 5G in nine markets in late 2018.

Besides faster access, connectivity might get a little cheaper in the future for users as long as 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 for now, it's all about the home. How will 5G develop next? What will 5G bring to us? Let's wait and see.

【1】Which of the following is the best to fill in the blank in Paragraph 1?

A.cheaper pricesB.more informationC.smaller shapesD.faster services

【2】The reason why 5G phones are NOT able to be used now is that _____.

A.teach companies are not able to set 5G phones

B.5G networks haven't been built to offer services

C.the speed of 5G networks is too fast for the regular phone

D.the signals used by 5G phones are not safe enough to bring

【3】According to the passage, which of the following is TRUE?

A.Booking cable TV is still popular among users.

B.5G is possible to be used to office working first.

C.5G will help us save money because of its cheaper costs.

D.Some communications companies are working on 5G tests.

【4】What is this passage mainly about?

A.The influence of 5G.B.The smartphones armed with 5G.

C.The development of 5G.D.The differences between 4G and 5G.

【題目】閱讀下面短文，按要求完成后面各題。

There were three big fish in the lake. One of them, Demo, was wise; another one, Jimmy, was half-wise; Martin, the third one, was stupid.

Some fishermen came to the bank of the lake with their nets(漁網(wǎng)). The three fish saw them.

Demo decided at once to leave, to make the long and difficult trip to the ocean. He thought, “I won’t discuss with these two about this. [4]They love this place so much that they call it home and will stay on. How silly they are! Their ignorance(愚昧) will cost them their lives.”

Seeing the wise fish had left, Jimmy thought, “My guide has gone and now I’ve lost my chance to escape(逃離).” He felt sorry for it and then thought, “What can I do to save myself from these men and their nets? Perhaps I should pretend(假裝) to be already dead.” So he did that. He went up and down with the water, helpless.

“Look at this! [5]最好的也是最大的魚是死的。” One of the men lifted him by the tail, and threw him up on the ground. He rolled(滾動(dòng)) over and over and moved secretly toward the water, and then, back in.

Now can you guess what the end of the third stupid fish is?

【題目】 Van Gogh was a famous painter. His work is sometimes described as Post Impressionism (后印象主義),” which means that his style of painting is similar to the Impressionism paintings. The “Impressionism paintings” were made only a few years before he started. But Van Gogh added his own ideas that were different from them. His style was very personal. Though he was influenced by many kinds of artists, he made few lasting friendships with any of them and was almost always alone.

Van Gogh lived a hard life. Only one of his paintings was sold in his lifetime and he was never to financially(經(jīng)濟(jì)上地)support himself. His brother, Then, often helped him, and the friends of his brother’s would help him as well. People who knew him would often describe him as a difficult person and hardly happy. His paintings, however, use very lively colors and sometimes seem pleasant.

It was in his paintings that Van Gogh was able to express himself clearly. Most of his relationships in life fell apart quickly. There are many sad stories of Van Gogh attempting to get married. Every woman refused him. The famous painter, Gaugin, went to visit him after Van Gogh had written to him, asking for a visit. When Gaugin arrived, Van Gogh was very excited. Gaugin respected Van Gogh’s talent, but the friendship only lasted a few months. The friendship ended when Van Gogh fought him with a knife.

No one had ever painted the way Van Gogh did. The colors of his paintings were lively and the shapes were strange and dream- like. His life was just as strange as his art, and it ended very early. However, since his death, his paintings have become some of the most famous artworks in the world.

【1】How many paintings did Van Gogh sell during his lifetime?

_________________________________________________________________

【2】Did Van Gogh get along well with other artists?

_________________________________________________________________

【3】What are the characteristics(特點(diǎn)) of Van Gogh’s paintings?

_________________________________________________________________

【4】When did his paintings become the best-known in the world?

_________________________________________________________________

【5】Please use at least two description words to describe Van Gogh’s life.
