哈喽～ 宝子们！今日份高考英语精读来啦🥰 专门挑选了2026届大湾区普通高中毕业年级10月联合模拟D篇，原版考场真题原文，中英逐段对照，生词短语都整理好了，附带高考级例句，边读边记轻松提分。

Natural disasters like earthquakes cause interruptions to communications, posing challenges to rescue efforts. So in 2008, China launchedthe Tiantong Project to set up a satellite 

communication system accessible to the public. Now the project has led to major advances in satellite communication and mobile phone development.

地震这类自然灾害通常会造成通信中断，给救援工作带来巨大挑战。因此在2008年，中国启动天通工程，搭建一套面向公众可用的卫星通信系统。如今这项工程推动卫星通信与手机技术取得重大进展。

In 2021 the Tiantong satellites formed a network covering the 

entire Asia-Pacific region. In August, 2023, Huaweireleased the world's first smartphone that supported satellite calls, by directly connecting to the Tiantong satellites.

2021年，天通卫星组网完成，信号覆盖整个亚太地区。2023年8月，华为发布全球首款可直连天通卫星、支持卫星通话的智能手机。

On December 18, 2023, a 6.2-magnitudeearthquake hit Gansu, causingwidespreadcommunication interruptions. Thanks to the Tiantong satellites, many of those trappedin the disaster were able to connect with the outside world through the satellite 

calling function on their smartphones.

2023年12月18日，甘肃发生6.2级地震，大范围通信中断。得益于天通卫星，许多受灾被困人员依靠手机卫星通话功能，得以和外界取得联系。

Direct satellite connectivity for mobile phones was previously believed to be impossible. To reach a small 

smartphone, the satellite needs to produce a very powerful signal.

此前人们认为手机直接接入卫星通信无法实现。要给小小的手机传输信号，卫星需要发射功率极强的信号。

When a large number of different high-power signals flood the satellite's transmitting antenna at the same time, they can lower the quality of satellite calls and, insevere cases, cause the entire system tocollapse. Since the 1970s, nearly all the previouscommercial communication satellite networks have

 experienced such major failures.

大量不同的大功率信号同时涌入卫星传输天线，会降低卫星通话质量，严重时会造成整个系统瘫痪。自上世纪70年代以来，几乎过往所有商用通信卫星网络都遭遇过这类重大故障。

This issue, known as PIM, was once abottleneck for further 

development of satellite communication technology. To solve this problem, Chinese physicists have establisheda physical model that can predict the occurrence of PIM withincredibleaccuracy.

这个被称为无源互调（PIM）的问题，曾是卫星通信技术进一步发展的瓶颈。为解决该难题，中国物理学家建立物理模型，可以极高精度预测无源互调现象的发生。

Based on this work, Chinese scientists developed effective 

methods to reduce the interference. The breakthrough opens the door for ordinary users to gainreliable satellite connection anytime anywhere.

基于这项研究，中国科学家研发出降低干扰的有效方案。这项突破为普通用户随时随地获得稳定卫星通信打开大门。
