There is nothing better than an old-fashioned swimming hole to get away from the heat this summer. Here's where to find the best places all over the country.
Madison Blue Spring, Florida
This naturally-formed spring (泉水) lives up to its name (名副其实): The water is blue and attractive. Now a state park, the 25-foot deep swimming hole lies inside a lovely forest next to the Withlacoochee River in northern Florida. If you are brave, you can even swim into the hole's underwater caves.
Santa Rosa Blue Hole, New Mexico
Like an oasis (绿洲) in the desert, this swimming hole keeps a perfect temperature of 62 degrees. The water is so clear that you can see the bottom. It is because the water, which is connected to an underwater cave system (系统), renews itself every six hours. You can even jump in from the edge of the broken sinkhole (沉洞), which is off the famous highway Route 66.
Switzer Falls, California
You can get out of the city with a trip to the Bear Canyon area of Angeles National Forest near Los Angeles. Follow the river to the 50-foot Switzer Falls, and you can pass lots of natural pools before and after the waterfall (瀑布). You can choose what you like! Getting there requires hiking a couple of miles out and back, but the cool water on a hot day is worth it.
Peekamoose Blue Hole, New York
Sometimes natural beauty can be nearly ruined because it is famous. The Peekamoose Blue Hole is in such a worrying situation. The swimming hole faced overuse, environmental harm and pollution. So strict rules were made to protect the quiet place several years ago. In the future, a permit (许可证) may be required to visit the pool to limit the number of visitors.
1.What is a feature of Madison Blue Spring, Florida?
A.It is beyond a forest. B.It can provide an underwater adventure (探险).
C.It is dug by workers. D.It's 25 meters deep.
2.What can we know about Switzer Falls from the passage?
A.It helps visitors avoid summer heat. B.It lies inside the city.
C.Visitors can drive directly to it. D.It has only one natural pool for visitors.
3.What will happen to Peekamoose Blue Hole in the future ?
A.It will be repaired to attract more visitors. B.Swimmers will not be allowed to visit it.
C.Visitors will become fewer than before. D.People will volunteer to protect it.
4.What does the underlined word "ruined" probably mean?
A.赞扬 B.毁坏 C.保护 D.联系
5.Where can you read the passage?
A.In a book review. B.In a novel. C.In a textbook. D.In a travel magazine.

From China to the United States, facial recognition technology is being used and tested like this at the Los Angeles International Airport. This pilot program that takes a picture of the passenger and compares it to the passport picture, is just one way facial recognition technology can be used for safety. The facial recognition technology can also be used for surveillance（监视）and for the commercial use（商业用途）.
Great achievements have been made in facial recognition technology in recent years.
The technology is used to identify a missing child. Computers are finally fast enough to process all the data that we need to process. Machines can now match faces even when the lighting isn't good or when a full shot of the face is not available. a side shot or moving image of the face may be enough for artificial intelligence to make a match.
Face first is one of many companies developing facial recognition software with endless possible uses. Try to imagine that everyday items that we have such as our house keys, our car keys, our ATM cards, our passwords are all starting to go away and instead, We’re going to be using facial recognition, Smart phones, of course are now using facial recognition. Laptops have facial recognition on them.
The ability to get an image of a person without permission comes with privacy worries.
“My biggest worry is actually not the government, it’s the big companies where there are really no limits on how they can share data, what they can use it for, how they can use it.”
Facial recognition researchers say some social rules should be created to guide the use of this technology, so it can be used safely to do good to society.
1.Where does the passage probably come from?
A. A guide book. B. A science report.
C. A fashion magazine. D. A novel.
2.From the first paragraph, we learn that the facial recognition technology is used ______.
A. in all the airports in America.
B. only for safety
C. for safety, surveillance and commercial use

3.What can we infer from the passage?
A. The recognition technology is perfect.
B. The recognition technology has made a lot of achievements.
C. The recognition technology has caused some privacy worries.
