When it comes to bucket-list（遗愿清单） adventures, swimming with sharks is near the top for a lot of adrenaline junkies. Many of the adventures on the list require scuba diving, but at some locations, even non-divers with a desire to get up close and personal with the top of the food chain can jump in and face their fears. Bahamas
I don't want to scare the non-shark lovers away from the beauty of the Bahamas, but there are sharks out there. From least scary to the most, here's where to get your Bahamian shark fix.
Compass Cay Marina is home to a large number of well-fed, friendly nurse sharks. In case you don't know it, a nurse shark is more like a giant catfish than a great white. You can walk right into the shallow water near the fish-cleaning station and pet these gentle guys.
Stuart Cove's in Nassau has been doing shark dives safely for decades. Caribbean reef sharks feed on fish-on-a-stick as divers kneel in the sand in awe. Reef sharks are some of the least aggressive species of shark.
As your fear subsides and you crave more sharks and more excitement, check out the folks at Jim Abernethy's Scuba Adventures in Fort Lauderdale. They operate live-aboard dive boats with regularly scheduled shark trips in the Bahamas. Expect to see tigers and hammerheads, as well as the Caribbean reef sharks. Hawaii
There are several shark species in the Pacific waters surrounding the Hawaiian Islands. Sightings of tigers, hammerheads, blues, and even great whites are not all that uncommon.
And While divers can expect to see these guys almost anywhere while diving in Hawaii, the Oahu's North Shore is the place to be for cage diving. Hawaii Shark Encounters takes shark education seriously and strives to educate customers about the need for shark conservation while providing a thrilling swim with sharks inside the safety of a cage. No diving skills are required－just bring your courage. Fiji
Scuba diving in Fiji is a definite bucket-list adventure for many divers－and the fish many
hope to see most is shark. Beqa Adventure Divers can make that happen for you. Sharks are protected in the Shark Reef Marine Reserve, so no worries about questionable practices. This is an uncaged dive, but per the company's website, it is a carefully managed feed, where participants observe, but do not interact（互动） with the sharks. Guadalupe Island
Home to a large population of great whites, the waters off the Mexico's Baja coast, attract divers willing to brave cold Pacific waters for some time in a cage watching the top fish of the ocean.
Nautilus Live Aboards operates six-day adventures from July to November using submersible（能在水下操作的） cages that descend to about 9 meters for a better opportunity to observe the sharks. You meet the expedition in San Diego, motor to Ensenada, cruise to Guadalupe, then spend three full days in the cages watching the predators. Non-divers are allowed, as air is supplied by hoses attached to the boat, but a minimum of a Discover Scuba course is recommended.

Crying is one of the rawest human emotions. We cry when we can’t hold inside what we feel. We cry when we’re at our best, and when we’re at our worst. By we, I mean all of us — men included.
But we never see other men cry. In no western culture has it ever been acceptable for men to shed more than a single tear, and even then it’s reserved for grand victories, defeats and deaths. Dutch research suggests that women cry between three and five times more than men.
Generally men and women cry over the same things — deaths, break-ups and homesickness, primarily, but researchers believe that men cry more often than women when it comes to positive events.
I want to admit, I’m a bit of a cryer. However, having never really experienced deaths in my life, a few weeks ago I experienced what it means to really, truly, pour my heart out in tears.
See, my dog — a loyal companion — was killed by a car right outside my house. Being a witness to this painful event left me in shock for a good hour, but then the floodgates opened. Over the next 48 hours, I might have cried 20 times. Once or twice I crouched (蹲) on the floor with my head in my hands and tears were the only outlet.
It is suggested in the book Adult Crying: A Biopsychosocial Approach that there’s a certain pleasure in crying. It helps ease stress when there is no other way to express ourselves.
In those days after my dog’s death, I remember thinking, “I’ve got to stop this crying”. It felt unmanly. It felt like a sign of weakness. I’ve since realized that tears are for everybody; they’re not gender-specific. They show we have sympathy, allow us to get rid of stress and just feel. 32.

Self-driving vehicles will rely on cameras, sensors and artificial intelligence (AI) to recognize and respond to road and traffic conditions, but sensing is the most effective for objects and movement in the neighborhood of the vehicle. Not everything important in a car’s environment
will be caught by the vehicle’s camera. Another vehicle approaching at high speed on a collision (碰撞) track might not be visible until it’s too late. This is why vehicle-to-vehicle communication is undergoing rapid development. Our research shows that cars will need to be able to chat and cooperate on the road, although the technical challenges are considerable.
Applications for vehicle-to-vehicle communication range from vehicles driving together in a row, to safety messages about nearby emergency vehicles. Vehicles could alert each other to avoid collisions or share notices about passers-by and bicycles.
From as far as several hundred meters away, vehicles could exchange messages with one another or receive information from roadside units (RSUs) about nearby incidents or dangerous road conditions through 4G network. A high level of AI seems required for such vehicles, not only to self-drive from A to B, but also to react intelligently to messages received. Vehicles will need to plan, reason and adapt in the light of information received in real time and to carry out cooperative behaviors. For example, a group of autonomous vehicles might avoid a route together because of potential risks, or a vehicle could decide to drop someone off earlier due to messages received, a foreseen crowding ahead.
Further applications of vehicle-to-vehicle communication are still being researched, including how to perform cooperative behavior. 28. What is the first paragraph mainly about?
A. The reasons for the accidents by self-driving vehicles. B. The research about applications for self-driving vehicles. C. The importance of artificial intelligence of self-driving vehicles.
D. The reasons for developing communication between self-driving vehicles. 29. What does the underlined word “alert” mean in Paragraph 2? A. Alarm. Govern.

Everyone can try his best to achieve. We don’t need to be the best, but to tough out the limits of what we are capable of. I gained this belief from my third grade teacher, the most special, honored, trustworthy, and loved person in my life.
Mr. Myrus was always perfectly dressed and spoke with the belief that talking to eight-year-olds didn’t mean he had to sacrifice proper statements or grammars. And he was demanding but he wasn’t unreasonable or cruel. He simply felt that no matter what your best was, you should achieve it.
As luck would have it, I met him again as my eighth grade math teacher. I was not, nor ever will be, gifted in math. I remember my struggles in class. “I don’t know the answer,” I would say, “I can’t do it!” “Perhaps you don’t know the answer,” he would say quietly. “Do you think we might figure it out together? How do you know what you can do until you try?”
Mr. Myrus lived around the corner, and I would often stop by to talk while he worked in his garden. I knew there was someone who let me know that if I had really tried, that was enough.
“Don’t be so hard on yourself,” he’d say. “Stop blaming yourself. Did you try your best? Well, then you’re not a failure,” he often told me these words.
Mr. Myrus died in 1978. I had never thought about his death. He was too young. I felt sorry. But when I think about him now, I don’t feel so sorry. He taught me to be kind, not only to others, but to myself. He taught me my own value. He taught me about honor, about truth, and about doing my best — and that all feelings and beliefs have dignity and deserve respect. And of all the things I know, this I believe: We can’t all be “the best”, but we can, each of us, be our best, and I know that’s true because Mr. Myrus told me that.
24. What can we learn about Mr. Myrus according to the passage? A. He is usually hard on the students.
B. He is responsible for his students and his teaching. C. He is a person who isn’t particular about what he wears. D. He sometimes is cruel and unreasonable to his students.
25. What does the underlined word “demanding” in Paragraph 2 most probably mean? A. Strict.
B. Serious.
C. Critical.
D. Careful.
26. Why did the author think he was a lucky dog? A. He had got a great belief from his teacher. B. Mr. Myrus had been his teacher for eight years. C. He became interested in math because of Mr. Myrus. D. He developed a good relationship with Mr. Myrus. 27. What can be inferred from Paragraph 3? A. Mr. Myrus thought it very easy to learn math. B. The author preferred other subjects to math.
