题目内容
【题目】 If you look at the top of your phone, you' ll usually see a little symbol that says 3G or 4G. The G" stands for the "generation" of your mobile network. But these symbols will become things of the past after the 5G network fully arrives.
The 5G mobile network is 100 times faster and has 1,000 times more capacity compared with 4G mobile network.
In recent years, China has paid great attention to the commercial (商业的) use of 5G and made great efforts to introduce the infrastructure(基础设施) for the 5G network. On March 30, Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate X smartphone, CGTN reported. Shanghai has also become the first city in China to start testing 5G networks.
5G will let people download and upload data faster than ever before. But 5G won't just bring faster mobile Internet. People can use it for many other things as well. For example, 5G will help to make self-driving cars safer. Today's self-driving test cars have one problem--lags. When the car sees" an obstacle, it sends this information to a data center and receives instructions.
However, it takes time to send and receive this information. With this kind of lag, the cars might crash because they don' t receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer, according to CNN.
5G could also be used to power the Internet of Things (IoT). This refers to a large online network that connects all things and people. Fast Internet speeds will be the key to developing this technology. For example, with loT, your refrigerator could order eggs online when it notices that there are no eggs left inside.
【1】In which city was 5G tested for the first time in China? .

你听说过5G吗？5G时代真的要来了。这篇短文给我们讲述了什么是5G，这个新的技术会给我们的生活带来哪些变化。
【1】细节理解题。根据短文第二段中On March 30, Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate X smartphone, CGTN reported. Shanghai has also become the first city in China to start testing 5G networks.可知，在3月30日，上海副市长进行了第一次5G视频通话，上海成为中国第一个开始测试5G网络的城市。由此可知应选A。
【2】细节理解题。根据短文第二段The 5G mobile network is 100 times faster and has 1,000 times more capacity compared with 4G mobile network.可知，5G移动网络的速度是4G移动网络的100倍。由此可知D选项是正确的。
【3】推理判断题。根据短文第四段But 5G won't just bring faster mobile Internet. People can use it for many other things as well. For example, 5G will help to make self-driving cars safer.可知，作者用自动驾驶汽车作为例子，告诉我们5G网络的使用不仅是给我们带来更快的移动网络，它的快速还有很多其他的用途。故应选D。
【4】词义猜测题。根据划线单词所在的语境When the car sees" an obstacle, it sends this information to a data center and receives instructions.“当汽车‘看到’一个……，它把这个信息传送给一个数据中心并接收指令”，再结合这里说的是自动驾驶汽车，因此obstacle是“障碍物”，故应选A。
【5】细节理解题。根据短文最后一段5G could also be used to power the Internet of Things (IoT). This refers to a large online network that connects all things and people.可知，IoT是Internet of Things“物联网”的缩写，它指的是一个大型的网络，这个网络将所有的东西和人们联系起来。由此可知这里应选C。
这是一篇科普说明文，短文介绍了新的5G技术给我们的生活带来的变化。短文主题明确，叙述清晰，但句式较复杂，专业性较强，在理解上有一定的难度。题型是阅读理解，题目设置有细节理解、推理判断、词义猜测等。如第3小题，题目问的是“作者以自动驾驶汽车为例是为了什么”，根据题目中提到的self-driving cars可定位到根据短文第四段But 5G won't just bring faster mobile Internet. People can use it for many other things as well. For example, 5G will help to make self-driving cars safer.可知，这个例子告诉我们5G网络的使用不仅是给我们带来更快的移动网络，它的快速还有很多其他的用途。故应选D。再如第4小题，这是一个猜词题，做题时应注意结合语境。根据划线单词所在的语境When the car sees" an obstacle, it sends this information to a data center and receives instructions.“当汽车‘看到’一个……，它把这个信息传送给一个数据中心并接收指令”，再结合这里说的是自动驾驶汽车，因此obstacle是“障碍物”，故应选A。
【题目】任务型。
When you are learning English, you find it not clever to put an English sentence, words, into your own language. Take the sentence “How do you do? ” as an example. If you look up each word in the dictionary, one at a time, what is your translation (翻译)? It must be a wrong sentence in your own language.
Languages do not just have different sounds, they are different in many ways. It’s important to learn the rules for word order( 顺 序 ) in the study of English, too. If the speakers put words in a wrong order, the listener can’t understand the speaker’s sentence easily. Sometimes when the order of words in an English sentence is changed, the meaning of the sentence changes. But sometimes the order is changed, the meaning of the sentence doesn’t change. Let’s see the difference between the two pairs of sentences.
“She only likes apples.” “Only she likes apples.”
“I usually have vegetables for lunch.” “Usually have vegetables for lunch”
When you are learning English, you must do your best to get the spirit(精神实质) of the language and use it as the English speaker does.
【1】 to learn English | |
【2】 way of learning English | Put a【3】into English word for word. |
Some【4】things about learning English | Learn the 【5】for word order. It is【6】for the listener to understand the sentence if the speaker 【7】words in a wrong order. Sentences may have the same meaning when the word order is changed, while others may have【8】 meanings. |
Conclusion | When learning English, we should try our best to: Get the 【9】of English. Try to use it in the 【10】way as English speakers. |
