    If you look at the top of your phone, you'll usually see a lite symbol that says 3G or 4G. The "G" is the generation(代)" of your mobile network (移动网络). But these symbols will become things of the past after 5G networks fully arrive.

    On March 30, 2019, Shanghai vice mayor (副市长) Wu Qing made the first SG video call on a Huawei Mate x smartphone, CGTN reported. Shanghai has also become the first city in China to start testing 5G networks.

    About 100 times faster than 4G networks, 5G will let people download (下载) and upload data (数据) 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-lag (延迟). When the car "sees" an obstacle (障碍物), it sends this information to a data center and receives instructions (指令).

    However, it takes time to send and receive this information. With this kind of lag, the cars might hit each other because they don't receive instructions in time. With 5G, this lag will be greatly lowered (降低), making the cars safer, according to CNN. 5G could also be used to help the internet of things (IoT,物联网). IoT is a large online network that connects all things and people. Fast internet speed will be the key to developing this technology. The IoT could be used in a lot of ways. For example, with IoT, your refrigerator could automatically (自动地) place an order online for eggs when it finds that there are no eggs left inside.

When do children start to talk? If you ask a group of parents when this happened, most will say "around 12 months of age". They will probably, even remember what the children said. Many parents keep a diary of their child's "first words".

We can never predict(预测) what a first word is going to be. Often it's the name for "mummy" or "daddy", but it could just as easily be the word for an animal or a favourite toy. Everything depends on what has most caught the child's attention. But one thing is certain: after the first word, others come quickly. By 18 months, most children have learnt about 50 words. By two, the total has risen to around 200.

Early words are actually one-word sentences. One of the first features (特征) of language a child learns well is to control the rise and fall of the voice to make the difference between saying and questioning. In English, daddy with a high rising tone(声调) means "Is that daddy?" Daddy with a high falling tone means "There's daddy." Of course, only very basic meanings can be communicated using tones alone. So it soon becomes necessary to learn some grammar.

In English, grammar means learning to put words in different orders. Children have to see that mummy push is different from push mummy. They start practising such changes at around 18 months. By two, they have learnt the basic forms of word order, and we hear them saying such things as man kick ball and where daddy go.

What are the parents doing all this time? They're acting as teachers and they always have an active role to play in their child's language learning.

 阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。
