【题目】 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 (臭氧层) 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 (官方许可证).

根据短文内容,完成下列小题。

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

________________________________________________________________________________

2Which health problem is the most common in Australia?

________________________________________________________________________________

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

________________________________________________________________________________

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

________________________________________________________________________________

5Why 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( 合乎逻辑地).

【题目】 Nowadays, more than half of the people in the world own a mobile. And most of them think it’s the most important thing they own. In r1surveys, people said they could live without their TVs and computers but not without their mobile phones. Most people said that they would rather l2their wallet than their mobile. Many people said they even took their mobile phone to bed with them ... like a teddy bear!

Why are people so in love with their mobile phones? Well, according to an article in an American newspaper, a mobile satisfies some needs of the humans. First, Safety, it m3us feel more secure. Second, Belongingness, we feel connected to other people when we are a4. And third, Esteem, we feel important when others see us using a mobile phone.

Many countries are now trying to prevent the use of mobile phones while driving. When people are talking or sending m5on their mobiles, they become distracted(注意力分散).In America, “distracted driving” resulted in more than 5,800 deaths last year. We may love our mobiles but there is a time and a place for them to be p6used. Driving isn’t a suitable place and neither is the classroom. Using a mobile in the classroom can result in “distracted learning.” That may not kill you but it can surely kill your g7. Do care about when and where to use your mobiles!
