【題目】 Going to the beach at the weekend in Australia is a very popular activity, just as much as going to a shopping centre or doing a sport. The Australian Beach Culture is similar to that in California and the Mediterranean.

Australians live by the sea, so it makes it very convenient for them to spend the weekend on the beach. Besides some places that can have winter weather, most of Australia is sunny throughout the whole year. This also provides a good chance for the development of the Australian Beach Culture.

However, when you go to the beach, there are some things you should consider. You should know that because the ozone layer (臭氧層) above some parts of Australia is thin, there is a great danger from the sunlight. The sun here is very strong and it burns the skin really fast. Australia has one of the highest rates(比率) of skin cancer in the world. So if you go to the beach, take hats and sunglasses.

Besides this, there are some other things that you should know. Sometimes the sea seems to be very peaceful, but the currents(水流) in the water can be very strong. So, if you don't know very much about the sea, you should swim only in the safe area between the flags at the beach. By the way, people are not allowed to sell anything on the beach without an official permission (官方許可證).

根據(jù)短文內(nèi)容，完成下列小題。

【1】What is a very popular activity at the weekend in Australia?

________________________________________________________________________________

【2】Which health problem is the most common in Australia?

________________________________________________________________________________

【3】Where should you swim if you do not have enough knowledge about the sea?

________________________________________________________________________________

【4】What do you need if you want to sell things on the beach?

________________________________________________________________________________

【5】Why can Beach Culture be developed in Australia?

Artificial intelligence( 人工智能) is the ability of a computer or a machine. The computer or the machine with AI can think and learn. It is also a field of study that tries to make computers "smart". John McCarthy, a scientist, came up with the name "artificial intelligence " over 60 years ago. Many things such as learning and problem solving can be done by computers, though not in the same way as people do.

An unusual goal of AI research is to create special computer programs. They can learn, solve problems and think logically( 合乎邏輯地). At present, AI can successfully understand human speech, recognize( 識別) human faces, operate self-driving cars and compete in some game systems like playing chess. However, some people consider AI a danger to humans if it develops too quickly. A famous British scientist also was not for this kind of technology.

Math is the basic language of AI. If students are good at math, they will be more likely to become successful AI designers in the future. We need not only bright students but average(普通的) students. As for average students, if they get enough math skills, they can also become successful AI designers. Besides, a good knowledge of computer science is also necessary for AI designing.
