When I first heard about geocaching（地理寻宝），I was skeptical. But the more I thought about it, the more it seemed like an interesting idea.I at least wanted to try it once.
Having familiarized myself with how the game works,I set out in search of my first cache. My trip took me through a series of lively hutong（胡同）,past a number of small temples, and right into the courtyard of a quiet youth hotel.I spent several minutes looking around, but couldn't find anything. Just before l was about to give up,I spotted a colorful object in the crack of a wall. Could it be the hidden cache?
At that moment a group of backpackers amved. According to the game's rules, people who are not in the game must not be allowed to find out about secret caches. So I pretended to make a phone call while waiting for them to leave. When the coast was clear,I grabbed the object. It was the cache! I opened it and pulled out a crumpled（皱的）sheet of paper with several names and celebratory messages written on it.I added my own and replaced the cache in its hiding place, ready for the next geocacher to find.
It may seem like a simple game, but the idea that there are caches hidden all around us is exciting. Once you're hooked, it's easy to set yourself the goal of finding every single cache in a neighborhood or even an entire city. The real treasure, however, is not the cache itself, but the places it takes you to.
Hunting for further caches has since introduced me to places which I didn't even know existed. Some are peaceful parks, while others are forgotten historical sites.A few caches have even been in places I passed regularly without giving them any thought. Now,Ifeel a much closer connection.

The Internet is full of headlines that grab your attention with buzzwords (流行词). But often when we click through, we find the content hardly delivers and it wastes our time. We close the page, feeling we've been cheated. These types of headlines are called "click bait".
A headline on Busin,esslnsider.com reads: "This phrase will make you seem more polite". First, when you click through, you find another headline: "Four words to seem more polite." Then, on reading the article, you find it's actually an essay about sympathy. And what are the four words? They're "Wow, that sounds hard." On some video websites, you might encounter headlines such as "Here's what happens when six puppies visited a campus". Turns out it's just some uneventful dog footage (镜头).
Nowadays, with the popularity of social media, many news outlets tweet (推送) click bait links to their stories. These tweets take advantage of the curiosity gap or attempt to draw the reader into a story using a question in the headline. These click bait headlines are so annoying that someone is attempting to save people time by exposing news outlet click bait through social media. The Twitter account @SavedYouAClick, run by Jake Beckman, is one such example.
Beckman's method is to grab tweets linking to a story and retweet them with a click-saving comment. For example, CNET tweeted "So iOS 8 appears to be jailbreakable but...", with a link to its coverage of Apple's product announcements. Beckman retweeted it with this comment attached: "... it hasn't been jailbroken yet."
Since founding the account, Beckman's Twitter experiment has brought him more than 131,000 followers. Beckman said that @SavedYouAClick is "just my way of trying to help the Internet be less temble." Asked about his goal, he said, "I'd love to see publishers think about the experience of their readers first. I think there's an enormous opportunity for publishers to provide readers with informative updates that include links so you can click through and read more.
The article on Businesslnsider.com turns out to be___.

Why are readers often cheated by tricky headlines?

Beckman attached his comment to CNET's tweet to ___

In the last paragraph, Beckman appeals that _____

In US, the potato is one of the most widely consumed crops. French fries are commonly found in typical American fast-food burger joints and cafeterias. French fries were introduced to the US when Thomas Jefferson served them in the White House during his presidency from 1801 t0 1809. Potato chips are popular with consumers as well.
The humble potato is more than just a kind of food. In many ways it's part of the American pop culture. Let's take a look at some pop culture potatoes.
Mashed Potato dance
The Mashed Potato dance is a craze that began in 1962. The name of the dance came from the song it accompanies, Mashed Potato Time, performed by American R&B singer Dee Dee Sharp. The move vaguely resembles that of the Twist dance style, by Sharp's fellow Philadelphian,
Chubby Checker.
Hot Potato!
Hot Potato! is an action puzzle video game released in 2001. In the game the player must drive a bus and clear the road of alien potato beings. The potato beings are either red or blue; when two like-colored potatoes touch each other, they disappear. .Over the years, Hot Potato! has received mostly positive reception from critics.
Mr. Potato Head
Mr. Potato Head is an American toy invented by George Lerner in 1949. The toy consists of a plastic potato model and a variety of plastic parts like hands, feet, ears and mouths. In 1952, Mr. Potato Head became the first toy advertised on television. This commercial revolutionized marketing and caused a boom that solidified this toy's place in American pop culture.

Picking a university is a tense period of asking yourself which institution is most relevant. That's why university rankings play such a vital role in students searching for their next academic direction. Rankings are also an inescapable part of the reputation and brand image of universities. "No university website is complete without the claim to be in the top 100 for something or other," reported the BBC. The reason is simple: Rankings help them to attract students, staff and research investment.
Currently there are numbers of university rankings, and each has its own list of criteria. But the main categories are the same: academic reputation, graduates' performance and faculty resources.
However, experts point out the ranking process isn't entirely reliable. Mark Kantrowitz, a US financial aid researcher, said university rankings were mostly just for show. He wrote in The New York Times. "It may give your parents better bragging rights, but that's about it."
Moreover, it's not difficult to see the limitations of university rankings. Many rankings focus on the number of times research work is cited (引用) by other researchers. It helps British and US universities to dominate global rankings because English is the favored language of academia, John O'Leary, a member of the QS academic advisory board, told The Gunrdian,. Also, rankings such as QS mainly focus on the qualities of the university rather than its students. "Any university ranking is likely to help students make better decisions about where to study, but the need to balance them with other more human factors is also important," said Phil Moss, an education and admissions consultant. "Advice from graduates or current students can be as valuable in providing a genuine insight into the experience or quality of a particular degree program. It can also add an element that rankings can never convey-the actual emotion of a university experience."
Why do universities consider rankings important?

What does the underlined "It" in paragraph 4 refer to?

According to John O'Leary, what helps British and US universities rank well?

Besides ranking, what does Phil Moss suggest you should refer to if you're picking a university?
