题目内容

【题目】一个重要的案例将在这次会议上讨论。

__________________________________________________________

【答案】An important case will be discussed at this meeting.

【解析】

important“重要的”;case“案例”;discuss“讨论”;at this meeting“在这次会议上”;important是以元音音素开头的单词,所以用不定冠词an表示“一个”;根据句意,讨论案例的动作将要发生,用一般将来时表示将要发生的动作,且主语case与谓语动词discuss之间是被动关系,所以句子用一般将来时被动语态,故空格处填An important case will be discussed at this meeting。故答案为An important case will be discussed at this meeting

【题目】 Karachi, Pakistan, is one of the hottest cities on Earth. In June 2015, more than 1,000 people died there during heat wave(热浪). “It was a terrible time,” Shahzad Qureshi said. “We needed to do something about it.” After the heat wave, Qureshi took action. He started Urban(都市的) Forest. The group plants trees in cities in Pakistan.

Trees help cool the air by providing shade(阴凉) and moisture(水分) through their leaves. Trees can help lower summer temperatures in cities by 2 to 5. Trees also provide a place for all kinds of animals. And they create a shady place where people can relax.

Urban Forest planted about 1,300 trees in a park in Karachi. The group uses a method that helps them grow quickly. In just three years, the trees were 30 feet tall. Qureshi hopes that one day, this park will become a forest of 50,000 trees. Since 2015, Qureshi and his team have helped cool the air by planting 14 urban forests in Pakistan. Twelve are in Karachi.

In 2017, Qureshi helped plant an urban forest at Karachi Grammar School. First, he met with students there. He taught them about how trees help the environment. Then the students planted trees in the schoolyard. “They were excited about the project,” Muneeza Shaikhali says. She's a headteacher at Karachi Grammar School. “They themselves had been experiencing the high temperatures in the summer months.”

There are many birds and colorful butterflies in the school. Students go outside during science class to study the forest. “It's like a library of trees in front of the kids,” Qureshi says. “They can learn the species(物种) and insects that are around. It's a beautiful thing to see.”

【题目】 Do you know 5G? It is the fifth generation(代)of mobile network technology. These new networks are coming.

China just issued commercial licenses(发放商用牌照)for 5G on June 6, 2019. This means that China's telecom companies will be able to offer 5G networks for mobile phone users.

Each mobile network generation is faster and more powerful than the one before it. 1G let us talk to each other. 2G let us send messages. 3G gave us data(数据)and the Internet. And 4G made all of these things faster. What's special about 5G?

5G has a very short delay between sending and receiving information. Now, 4G takes about 100 to 200 milliseconds(毫秒)to send and receive data. But 5G will get it down to 1 millisecond or less-this is almost real-time.

'This big change will not only make our mobile Internet fasterbut also deeply change our lives. Read on to find out how.

5G + entertainment(娱乐)

5G networks are about 100 times faster than 4G. This means you can download a movie in seconds using 5G.

Also, virtual realityVRgames will become more popular with 5G. The short delay of 5G will make the games feel even more real.

5G + transport

5C will also bring us safer self-driving cars. These cars can send signals(信号)to each other. They also talk to traffic lights and road sensors(传感器). 5G will allow cars to react(反应)even faster than human drivers.

5G + smart homes

5G also makes the Internet of things possible. Internet of things is a large network that connects everything to the Internet. Smart homes are part of it.

For example, your toaster can automatically(自动地)start making breakfast after your alarm rings. And if its sensor feels the air becoming dry, a smart sprinkler(洒水器)could water your plants by itself.

1What's the writer's purpose in writing the third paragraph?
