China is determined to land its astronauts on the moon and set up a scientific station there,according to a project leader.

Zhou Yanfei,deputy chief designer of China's manned space program,said on Friday that China wishes to use the manned lunar missions to carry out scientific surveys and technology demonstrations,explore ways to develop lunar resources and strengthen the nation's space capabilities.

"A new wave of lunar explorations has been emerging in the world,with participants aiming to make sustainable missions to deepen knowledge of the moon and exploit resources there,"he said in a report delivered at the 2020 China Space Conference in Fuzhou,Fujian province."Unlike other nations,China must depend on its own science and technology to realize our goals."

The country is independently able to land its astronauts on the moon because it has the technologies,a group of well-trained,innovative professionals and high-efficiency research and management systems,Zhou said."However,our existing carrier rockets can't perform landing missions to the moon because they are not powerful enough.The Shenzhou- series manned spaceships are not suitable for lunar expeditions.We don't have a lunar landing capsule,"he said."Our ground support system was designed for operations in low-Earth orbit rather than on the lunar surface.

To solve the problem, we set out to produce a powerful launch vehicle. Zhou said researchers thought about two approaches-making a new heavy-lift rocket,or adjusting the next-generation rocket designed to carry astronauts,which is under development.Researchers prefer the latter approach because it would be easier to design and make and would become operational earlier.

The new rocket is being designed at the China Academy of Launch Vehicle Technology.Its main body will be 87 meters tall,with a diameter of 5 meters,which would make it almost twice as tall as the Long March 5,currently the biggest of China's rockets.

1. Which is NOT the goal of the manned lunar mission?
A.To explore lunar resources.
B.To perform scientific experiments.
C.To set up a scientific station.
D.To strengthen the national space power.
2. What is the main idea of paragraph 4?
A.China is not capable of pursuing the manned lunar program.
B.There are still difficulties in pursuing the manned lunar program.
C.There are a series of steps in the Manned Lunar program.
D.It is manageable to carry out the Manned Lunar program.
3. What can we infer from the passage?
A.Nations must depend on themselves to explore the moon.
B.The Long March 5 is the biggest of China's rocket.
C.The newly-designed rocket will not carry astronauts.
D.Producing a powerful launch vehicle is the most difficult part in the program.
4. What do the figures in the last paragraph imply?
A.The new rocket is big enough to perform landing missions.
B.The new rocket is being made to launch lunar spaceship.

【推荐1】The death of the plastic credit card could be a step closer as high street names including McDonald's and the Co-op prepare to test a breakthrough finger-scanning payment technology.

FingoPay, developed by British start-up Sthaler, uses a biometric reader to scan the veins of a shopper’s finger, building up a “map” that is unique to each individual.

By connecting this pattern with a credit card or bank account, the company plans to let shoppers pay simply by placing their finger in a pocket-sized scanner, doing away with cash and credit cards.

Sthaler, founded by former music industry executive Nick Dryden, will begin testing the technology next month in Proud, a London nightclub. Mr. Dryden said McDonald's is experimenting with a pilot of the technology, and that Sthaler is also planning a project with Co-op’s food stores.

It comes amid growing interest in using biometric identification in payments, which backers believe are more secure and efficient than passwords and PINs. Apple Pay, which uses the iPhone’s fingerprint technology, launched in the UK in 2015 and was followed by the Android equivalent in May 2016.

Hendrik Kleinsmiede, the director of Visa Europe’s innovation arm Collab, which is backing Sthaler, said the Fingopay technology was less immune to problems such as wet and dusty fingers or fraud. “People are ready to accept biometrics as a secure authentication mechanism,” he said.

Sthaler says the chance that two people have the same vein structure is 3.4bn-to-one, making it virtually impossible to crack. The vein scanner, developed by Hitachi, is already being used by Barclays to identify business customers as well as in cash machines in Japan, but Sthaler has the unique rights to license it to retailers.

In the trial at Proud set to begin in September, the technology will be used to speed up waiting times at the bar both by cutting down on cards and by being able to suggest drinks based on what a patron has previously ordered.

1. Which of the following is TRUE about Fingopay?
A.It works by identifying shoppers’ fingerprints.
B.It scans the finger veins to identify shoppers.
C.It was first tested on Barclays’ cash machines in Japan.
D.It is currently being tested in the Co-op Group’s food stores.
2. According to Hendrik Kleinsmiede, ________.
A.it is impossible to find two people who share the same vein structure
B.people have to clean their hands before they use Fingopay
C.it won’t be long before biometrics are more widely used
D.Fingopay technology is much more effective than passwords and PINs
3. What can we conclude from the last paragraph?
A.The use of Fingopay technology has bought in more customers.
B.Fingopay technology helps businesses to meet customers’ needs.
C.Fingopay technology could increase the sales of certain drinks.
D.The use of Fingopay technology wasn’t allowed in the trial at Proud.
4. What might be the best title of the passage?
A.Pay with your vein: Fingopay
B.Cedit cards vs. Fingopay
C.Different ways of payment
D.A new technology: fingerprints

【推荐2】What Is the Metaverse (元宇宙) Tech Companies Aim to Build?

You may have heard the term metaverse to describe a new virtual world that major technology companies aim to develop. The word is a combination of the prefix meta—which means beyond—and verse, which relates to the universe.     1    . In his story, people wore virtual reality (VR) headsets to interact inside a game—like technology world.

The main technologies that would drive such a world would be VR, and augmented reality (AR).     2    

A company has invested much money in VR and AR technologies to create the most realistic virtual interactions possible.     3     Another has also been developing VR and AR tools to bridge the digital and physical worlds.

With the help of AR gasses, individuals might be able to see a large amount of information pass before their eyes while moving around in a city. This could include traffic and pollution data, information on he natural environment or local history.     4     These include the ability for people to be transported to digital settings that feel very real, such as a sports stadium or a mountaintop.

    5     These involve players around the world interacting in virtual environments and even permit users to buy digital items with real money. Cathy Hackl is a technology expert who advises companies on the metaverse. She told that the younger generation in much more willing to attach real meaning to virtual experiences and objects.

A.People linked to the metaverse would be connected a all times.
B.Such a system could one day be used with headsets in a metaverse.
C.It has also created a new team to specially develop metaverse products.
D.A metaverse environment might look a lot like many of the online video games.
E.The term appeared in the 1992 science fiction book written by Neal Stephenson.
F.Other yet-to-be invented technologies would likely also be used to improve experiences.
G.However, most predictions for a future metaverse see the technology going much further.

文章大意:这是一篇说明文。文章主要介绍了ChatGPT的工作原理以及带来的负面影响。

【推荐3】From writing Shakespeare-style poetry to making music, ChatGPT has amazed he world since its launch in late 2022 by the US-based company OpenAI. It even passed several law exams in four courses at the Unlversity of Minnesota, US.

The AI program can answer questions on a whole host of topics and write essays, stories and any other written texts you can think of. It does this by drawing on information collected from a large corpus (语料库) of text data.

What makes ChatGPT so impressive? As Sam Altman, the CEO of OpenAI said n an interview, “It’s not actually a fundamentally new technology that made this (ChatGPT) have a moment.” According to MIT Technology Review, ChatGPT is based on GPT-3, a large language model. Because texts are more complex than the meaning of every word combined, language models require a type of neural network (神经网络) that can make sense of texts.

One breakthrough behind today’s model is a network called Transformer, which was invented by Google researchers in 2017. The neural network can infer word meanings by tracking where the word appears in a sentence. Transformer can therefore gather the meaning of texts more accurately.

The GPT models were built by OpenAI combined Transformer with unsupervised (无人指导的) learning, meaning that the models can learn by themselves without being told what to look at. ChatGPT can now generate human-like responses instantly due to the large scale (规模) of texts It made sense of and learned from.

“One of the biggest problems with ChatGPT is that it comes back, very confidently, with falsities,” Michael Wooldridge at the Alan Turing Institute in London, UK. This means that ChatGPT doesn’t know the truth about the world — it learns information from various resources but It cannot decide what is true or false. As for education, many US schools recently banned students from using ChatGPT on school networks because students began to use it as a shortcut for essays.

1. What aspect of ChatGPT is most impressive?
A.The neural network.B.The large text database.
C.The ability to combine words.D.The application of technology.
2. What is the key to ChatGPT’s response like humans?
A.Data-based communication.B.Learning from masses of texts.
C.Human-guided machine learning.D.Collecting texts for a large corpus.
3. What is the author’s attitude toward ChatGPT?
A.Supportive.B.Confused.C.Objective.D.Confident.
4. What can be a suitable title for the text?
A.Is ChatGPT a Good Translator?
B.Should ChatGPT be Banned at School?
C.Can ChatGPT Choose True Information?
D.Will ChatGPT be the Wonder of Modern Technology?
