In four years, the space agency plans to land the first woman ever on the Moon through its Artemis program, which calls for $28 billion in funding through 2025' for Stage I, NASA said in its news release. Artemis is named after the Greek goddess of the moon and twin sister of Apollo. NASA's Apollo 11 mission succeeded in landing the first 12 men on the moon on July 20, 1969.

One billion dollars of the budget will go directly to the development of a commercial human lunar system that will take humans to the moon's surface, NASA' said. A share of $651 million will be used to support the Orion Spacecraft and the rocket for the moon mission—called the Space Launch System or SLS.NASA has already spent at least $11.9 billion on the SLS, which was supposed to be ready by December 2017. The spacecraft is complete, NASA said, and the main stage and four attached rockets are undergoing final tests in preparation for a "critical hot fire test this fall."

NASA's Artemis I mission is on track to launch in 2021 with two test flights around the Moon without astronauts. However, NASA will send robots to the Moon twice in 2021 in order to "send dozens of new science investigations and technology demonstrations".

Artemis II is set to launch in 2023 with astronauts on board in preparation to have Artemis III bring astronauts back to the surface of the Moon. The astronauts will be fitted with modern spacesuits that allow for greater flexibility and movement than the spacesuits used by other Apollo-era astronauts, and they will be tasked with collecting samples and conducting a range of science experiments over the course of nearly seven days.

The Artemis program will search for and potentially explore resources' such as water that can be turned into other usable resources such as oxygen and fuel, and NASA hopes to develop new 'mobility capabilities that will allow astronauts to explore new regions of the Moon.

Hello, everyone! My topic today is "Confidence".

Thanks for listening!

    Last Sunday, on my return from a trip to Waterloo, I took a taxi from Waterloo Station to my home. We hadn't gone very far 1 the traffic light changed to red. We waited for minutes. Just as the light was changing to 2, a policeman pulled open the door of the taxi,3 in, shouted to the driver, “4that blue car in front. It's been stolen.” and he sat down on the seat beside me. Then he seemed to see me for the first time for he politely 5, “ Sorry sir, but I've got to catch that car.” The taxi driver 6 the speed without saying anything. After a few hundred yards the blue car stopped at 7 traffic light and we drew up 8. The policeman got out, ran round to the driver's door of the blue car, opened it and 9the driver out. I couldn't hear what he said , but after a few minutes the policeman 10 to me and I went up to him. He asked me to help him take the car thief to the nearest11.

    The three of us got into the 12. We drove off 13 the taxi following. I didn't like sitting next to the 14, who was a young , rather tough-looking man, but I had no 15. Fortunately it wasn't far to the police station. 16 we got there the policeman took my name and address, thanked me for my 17 and said I could go home now. So I got back into my taxi and we drove off again. The taxi driver said 18 that it was the second time in a month he had been 19to help the police, and he 20 it wouldn't happen again.

    Do your family often take a trip? For most families, a trip in a car to an unfamiliar (不熟悉的) area often goes with the question about which way (take). This is not the case, however, in the Williams family. They never get (lose) when five-year-old Daniel is with them. That's because Daniel has the unbelievable(able) to tell them the best way to get from one place to another anywhere in England and what's more, he doesn't need a map-he can do itthinking.

    Daniel(be) interested in place names since he first learned to talk. When he was about three, he started asking his parents questions about how the roads they drove along joined up, andsoon became obvious that he had a super memory for maps. He had no difficulty(remember) the roads he saw from the car window.

    Now, after school, Daniel's (favor) game is drawing maps of the road systems in the places he hasn't visited. His parents have no idea where his particular talent comes fromno one else in the family has it. Although he has other(hobby) Daniel's greatest goal in life is to become a mapmaker.

It is sometimes thought that the longing for material goods, the need to buy things, is a relatively modern invention.Trade or shopping is certainly an ancient desire, and existed before our ancestors invented writing, laws, cities or farming, even before they used metal to make tools.

Humans are born to trade. Evidence from hunter-gatherers suggests that the exchange of food and other necessary things comes naturally, as well as the ability to keep a record of the credits involved. And once trade begins, the benefits are hard to resist.

Ancient local coastal people in northern Australia traded fish hooks, along a chain of trading partners, with people living 400 miles inland, who cut and polished local stone to make axes (斧子). Finally, both groups of “producers”, by concentrating on things they could produce and exchanging them for other things they needed, benefited as a result.

Trade in the necessities of life, such as food and simple tools, is not really surprising, considering the link between these basic items and survival. What is surprising, though, is that our taste for unnecessary expensive objects also goes back a long way.

In South Africa, 100,000-year-old decorative dyes (染料) have been found in an area where none were produced. Small round pieces of glass 76,000 years old were also found at the same place. The earliest jewellery known to us were not just random findings — they were grouped together in size and had holes like those used for threading onto a necklace.

Archaeologists argue that trade prepared the way for the complex societies in which we live today. However, their modern equivalents — fast cars and expensive clothes — hold the same attraction for us as “trade goods” did for people 100,000 years ago.

A. And we don't need shops or money to do it.

B. These are powerful evidence for cash purchase.

C. In fact, its roots go back to the beginning of humanity.

D. However, first trade began from the exchange of objects.

E. Modern-day shoppers may not be impressed by ancient glass pieces.

F. It is thought that these goods were bought at least 30  kilometres  away.

G. Every individual along the chain made a profit, even if he produced neither himself.
