If you plan on visiting to Fiji, you are probably looking for some fun things to do. Below are four unusual places.
The Poseidon Resort
The Poseidon resort is an underwater resort that gives visitors a beautiful view of sea life. This resort covers 255 acres. It’s covered and surrounded by a lagoon (咸水湖) that covers 5,000 acres and is about 90 feet under water, giving you a beautiful view of sea life right before your eyes. This resort even has a hotel for those who would prefer to have the unusual experience of sleeping and waking up to the beautiful scenery all around them.
The Sabeto Mud Pool
If you’re looking for something unusual to do, you can’t pass up the mud pool at Sabeto. It is located in a mountain range with a huge group of Geothermal (地?zé)岬? pools full of nice, warm mud. Getting down and into the mud in the pool is believed to have benefits for healthy skin. This is unusual, but adults and especially kids will love it.
Fire Walking
Fire walking in Fiji is believed to have originated on the island of Beau. Fire walking is when you walk on white-hot stones barefoot. To do this, you have to be mentally prepared for it. Trust me; there is a lot of preparation and strict rules that travelers follow in order to do this safely.
The Fiji Museum
The Fiji museum is unusual due to all the amazing artifacts you’ll see dating back 3,000-4,000 years. This museum has a certain attraction that makes it funny—a shoe. It’s been said that a man named Thomas Baker was eaten by the locals several centuries ago and the only thing left was his shoe. This unusual museum is a great idea if you bring the whole family to Fiji.
小題1:Visitors who have the unusual experience of sleeping at the Poseidon resort can _________.

科目：高中英語(yǔ) 來(lái)源：不詳 題型：閱讀理解

If you’re planning on traveling, there are a few simple rules about how to make life easier both before and after your journey.
First of all, always check and double-check departure (起程) time. It is amazing how few people really do this carefully. Once I arrived at the airport a few minutes after ten. My secretary had got the ticket for me and I thought she had said that the plane left at 10:50. When I arrived at the airport, the clerk at the departure desk told me that my flight was closed. Therefore, I had to wait three hours for the next one and missed an important meeting.
The second rule is to remember that even in this age of credit cards, it is still important to have at least a little of the local currency(貨幣) with you when you arrive in a country. This can be necessary if you are flying to a place few tourists normally visit. A few years ago I was sent to Tulsa, Oklahoma. I flew there from London via(經(jīng)由)Dallas, with very little time to change planes in between. I arrived there at midnight and the bank at the airport was closed. The only way to get to my hotel was by taxi and because I had no dollars, I offered to pay in pounds instead.
“Listen! I only take real money!” the driver said angrily. Luckily I was able to borrow a few dollars from a clerk at the hotel, but it was embarrassing (令人難堪的).
The third and last rule is to find out as much as you can about the weather at your destination before you leave. I feel sorry for some of my workmates who travel in heavy suit and raincoats in May, when it is still fairly cool in London or Manchester, to places like Athens, Rome or Madrid, where it is already beginning to get quite warm during the day.
小題1: According to the passage, it’s obvious that______
A．The author learns some rules of traveling from his own experience.
B．The author doesn’t plan his trips or journeys carefully.
C．Englishmen like to wear heavy suits wherever they travel
D．The America taxi driver never travels to England.
小題2:What should you make sure first before setting off?
A．When you will leave.B．Where you will go.
C．How you will travelD．Whom you will go with.
小題3:According to the passage, the driver was angry because_______
A．the author gave him false money
B．the author did not give him the local currency
C．the author did not give him money
D．the author had no enough change
小題4:Which of the following is TRUE according to the passage?
A．The author tells people to choose warm places as their travel destinations.
B．You don’t have to take credit cards when traveling.
C．You should know more about the weather of the place you’ll visit.
D．You should take enough change when you travel to other countries.
小題5:What is the main idea of the passage?
A．A few simple rules about how to make life easier both before and after your journey.
B．Always check and double-check departure time.
C．It is important to have the local currency with you when you arrive in a country.
D．To find out as much as you can about the weather at your destination before you leave.

A company advertised in the newspaper for a sales position. Details of the requirements, salary and benefits were given. It was also clearly stated that applicants needed to take an aptitude test (能力傾向測(cè)試) and an interview. However, looking at the whole advertisement, one could not find any contact information of the company.
Most interested applicants thought that it was the company’s HR department’s carelessness or a printing error. They therefore waited patiently for the newspaper to publish an amendment(訂正). But instead of waiting for the newspaper to publish the company details, another three applicants took the initiative(主動(dòng)性) to find out the company’s contact information themselves.
Tim did a search on the Internet. By typing the company’s name, he easily obtained all the information including its contact number. Lisa called up the local telephone number search service and found out the company’s office number. She called up the office and got the required contact information. Donna put in a greater effort in her search. She remembered seeing a poster by the same company in the city so she drove all the way down and made a few rounds to search for it. She finally found it together with the company’s contact information.
Three days after that advertisement was published in the newspaper, most interested applicants were still waiting eagerly for an amendment. On the other hand, the application letters and resumes of Tim, Lisa and Donna had already reached the hands of the company’s HR manager. They were then called up for an interview. During the interview, all went well and immediately they were hired. The three of them were a little surprised at how fast things went on. They were expecting for an aptitude test as stated in the advertisement. The HR director answered them, smiling, “Our test is hidden in the advertisement itself. To be a good salesperson in this age, he or she has to be broad-minded and very importantly, does not follow rigid (死板的) steps or rules. You are all clever. In a short time, you’ve managed to find ways of contacting us. It shows clearly that you have passed the test with flying colors!”
The fools sit around waiting for their chances whereas the wise actively take actions with great initiative.
小題1:According to the passage the company wanted to test the applicants’ ______.
A．sales skillsB．carefulnessC．a(chǎn)ttitudeD．initiative
小題2: Whose search skill is the easiest of all?
A．Tim’s.B．Lisa’s.C．Donna’s.D．None.
小題3:What can we infer from the passage?
A．The HR manager of the company made a mistake.
B．The company meant to omit (遺漏) its contact information.
C．The HR manager of the company was unfit for his / her job.
D．A printing error occurred in the advertisement in the newspaper.
小題4:Which of the statements is NOT correct according to the passage?
A．Many applicants thought the company made a mistake.
B．The advertisement was very special to many applicants.
C．Whoever found the company’s contact information didn’t need to have an interview.
D．The company needed broad-minded and clever salespersons.
小題5:The writer wants to tell us through this passage that ______.
A．no contact information seen in an advertisement might not be the company’s mistake
B．a(chǎn)pplicants should be careful not to be fooled by the company’s advertisement
C．opportunity always belongs to whoever is active and broad-minded
D．there are many successful chances to be found in this age

科目：高中英語(yǔ) 來(lái)源：不詳 題型：閱讀理解

When someone gives you advice, listen without judgment, try to find value in what you’re hearing, and say “Thank you”．This wise advice is easy to understand yet hard to practice．I’ll give you an example from my life when I totally blew it in terms of practicing what I teach．
In my work I travel constantly．I always put off going to the airport until the last second．My wife, Lynda, was sitting next to me in the front seat．I was racing along and not paying much attention．Lynda cried out, “Look out! There is a red light up ahead．”
Being a trained behavioral science professional --- who teaches others the value of encouraging advice --- I naturally screamed at her, “I know there is a red light up ahead! Don’t you think I can see?” When we arrived at the airport, Lynda didn’t speak to me．I wondered why she seemed mad at me．
During the flight to New York, I did a cost-benefit analysis．I asked myself, “What was the cost of just listening when Lynda called out the warning? Zero．” I then reasoned, “What was the potential benefit? What could have been saved?” Several potential benefits came to mind, including her life, my life, and the lives of other people．
I landed in New York feeling ashamed of myself．I immediately called Lynda and told her my cost-benefit story．I convinced her, “The next time you help me with my driving, I am just going to say, ‘Thank you．’”
A few months passed, and I had long forgotten the incident．Again, I was racing off to the airport, when Lynda cried out, “Look out for the red light!” I was embarrassed, and then shouted, “Thank you!”
I’m a long way from perfect, but I’m getting better．My suggestion is that you get in the habit of asking the important people in your life how you can do things better．And be ready for an answer．Some people may tell you things like “Look out for the red light．” When this happens, remember that there is possibly some potential benefit．Then just say, “Thank you．”
小題1:What do we know about the author?
A．He is expert at behavioral science．
B．He is gifted in cost-benefit analysis．
C．He always takes his wife’s advice．
D．He often runs the red traffic light．
小題2:The underlined part “blew it” in Paragraph 1 probably means “__________”．
A．lost personal judgmentB．forgot the practical method
C．became annoyed with the adviserD．failed to say “Thank you”
小題3:It can be inferred from the passage that people __________．
A．should give their opinions patiently
B．tend to be defensive when given advice
C．had better study behavioral science
D．intend to follow others’ suggestions
小題4:The purpose of the passage is to advise people to __________．
A．do a cost-benefit analysis in daily life
B．discover potential benefits
C．learn from the author’s experiences
D．treasure others’ suggestions
