Space junk, Ancient Mayan city discovered, Tag questions, Habits

On today’s podcast, Caty Weaver and Mario Ritter, Jr. host the show. Caty tells listeners what they are going to hear.
(:54) First, Bryan Lynn has a report about the European Space Agency. ESA officials are reportedly in talks with America’s SpaceX to sign a deal to limit space junk. Reuters reports that the aim to get SpaceX to join an existing international agreement. It aims to prevent new debris from entering Earth’s orbit by 2030.

(6:33) Next, John Russell has a report on an ancient city “discovered” in Mexico. Researchers in Mexico have discovered a large, lost Mayan city, called Valeriana. It was discovered by chance thanks to Lidar, or Light Detection and Ranging. It is a technology that uses lasers to map the Earth’s surface. The researchers said they identified more than 6000 structures.
(10:20) After that, Jill Robbins and Jim Tedder present Everyday Grammar. This week, Jill looks at those little questions English speakers put at the end of a sentence. They can be positive or negative. They are known as tag questions. Tag questions also often used reduced forms, so there is a lot to consider about the use of tag questions although they are extremely common in spoke English. learningenglis...
(16:50) Following Everyday Grammar, Jill and Caty have a chat about what a tag is and where the word tag might be used.
(19:05) Finally, Jill and Andrew Smith examine how we talk about habits in English. Lesson 51 of Let’s Learn English is about habits. Anna wants to run a marathon but learns that it takes a lot of preparation to do it. Then the two describe what it is to do something on “a regular basis” and the importance of setting goals when forming habits. learningenglis...
