Tiny monitoring devices have become an increasingly common way for scientists to study elusive animals that are difficult to track on a day-to-day basis. However, now it seems that smart. seals have caught on to the trick and are using it to their advantage to catch fish!
To find out if that is true, a team of researchers from the University of St. Andrews in Scotland selected a group often young grey seals that had neither encountered the ocean nor been exposed to any kind of acoustic（声音的）tags. The researchers then placed the seals one at a time, inside a pool that contained 20 foraging boxes, only two of which housed fish — one with tags and the other without.
Each seal was allowed to explore the boxes twenty separate times. In order to ensure that mammal was not depending on its memory, the fish were moved to different boxes each time. At first, there was no difference in the amount of time it took the seals to discover the tagged and untagged fish. However, after they had been in the pool a few times, they started locating the tagged fish much faster.
To confirm that this indeed was the case, there searchers conducted a second experiment using two boxes — one with pieces of fish and the other with just acoustic tags. Sure enough, the seals were all attracted to the one that was sending out signals.
While this experiment involved only seals, the researchers believe that other marine mammals may also be using the information to catch prey. Sadly, predators like sharks that have been tagged by scientists may be negatively affected, as pings they emit could warn their prey of their presence. Besides potentially messing up nature’s food chain, the “dinner bell” effect of the acoustic tags could also mean that the conclusions reached by previous fish studies may not be correct. Now that the secret is out, scientists will have to come up with another way to conduct their studies — one that is not detectable by the crafty marine animals.

When you are traveling, it’s vital to know about the customs and etiquette（礼仪，礼节）of the global village. What we consider polite behavior at home isn’t always accepted outside our borders.
Etiquette of Gift Giving Gift giving should be a happy, positive experience. When selecting a present for someone in Netherlands, don’t purchase fancy kitchen knives or scissors. Giving sharp, pointy objects as gifts is considered unlucky. Be careful when presenting flowers to a friend or a business partner in Russia. Yellow blooms suggest cheat or a relationship break up. Traditionally, red carnations are placed on the tombs of the dead. Writing cards or notes while visiting South Korea, be mindful of your pen’s ink color. Writing a person’s name in red ink traditionally suggests that the person has passed away—an important point to remember when giving a birthday card.
Eating Customs Being early or on time is viewed as being rude, too eager or even greedy in Venezuela. If you are invited to someone’s home for a meal, it’s recommended that you arrive 10 minutes later than the requested time. When having a meal in Egypt, don’t use the salt shaker （盐瓶）. It’s insulting to your host to spread salt on your food, which means that you find the meal terrible. Japan is a very polite nation, and their fondness for etiquette extends to the use of chopsticks. According to Japanese custom, if you’re in the middle of eating, use the opposite end of your chopsticks to secure food from a shared plate. When doing business in Turkey, it’s the custom for your host to pay for your meal. Requests to split the bill won’t be accepted. If you would like to pay your fair share, Turks recommend inviting your host to a follow-up meal.
21. Which of the following is true according to the passage?

23. where is this passage probably from?
I live in Hollywood. You may think people in such an attractive, fun—filled place are happier than others. If so, you have some mistaken ideas about the nature of happiness.
Many intelligent people still equate happiness with fun. The troth is that fun and happiness have little or nothing in common. Fun is what we experience during an act. Happiness is what we experience after an act. It is a deeper, more long—lasting emotion. Going to an amusement park or ball game, watching a movie or television, are fun activities that help us relax, temporarily forget our problems and maybe even laugh. But they do not bring happiness, because their positive effects end when the fun ends.
I have often thought that if Hollywood stars have a role to play, it is to teach us that happiness has nothing to do with fun. These rich, beautiful individuals have constant access to exciting parties, fancy cars, expensive homes, everything that spells “happiness”. But in memoir（回忆录）after memoir, celebrities reveal the unhappiness hidden beneath all their fun: depression, alcoholism, drag addiction, broken marriages, troubled children, and long—time loneliness. The way people hold on to the belief that a fun—filled, pain—free life equates happiness actually decreases their chances of ever attaining real happiness. If fun and pleasure are equated with happiness, then pain must be equated with unhappiness. But, in fact, the opposite is tree: More times than not, things that lead to happiness involve some pain.
As a result, many people avoid the very efforts that are the source of tree happiness. They fear the pain inevitably brought by such things as marriage, raising children, professional achievement, religious commitment, charitable work and self—improvement.
24. According to the passage, “fun activities” ________.
25. In the author’s opinion, those Hollywood stars ________.
26. It is difficult for people to find real happiness because ________.
27. The main purpose of the text is to ________.
Hey, ladies! It’s summer again and it’s time for a new you! No more make-up, no more pretending! Yes, that’s right! It’s time to stop making ourselves beautiful for the camera, and start posting confident pictures without all the make-up and extra tricks we add onto ourselves in the hope of appearing more attractive and beautiful. Because believe it or not, we already are!
After we wash our face and go to bed, it is not so perfect. You know it the face we should confidently be showing to the world! Who cares if you have pimples（面痕）or your eyes look small, or if you have crow’s feet? Guess what? Those are actually what make you such a beautifully grown woman. And any person who doesn’t think so is just not as strong as you.
Nowadays we are so prone to do anything and everything to make us look as young and perfect as possible. Yet the troth is, by doing this, we are actually making our tree skin get worse and badly affected by all the junk we put on. We are making ourselves believe that by changing our appearance we will be more accepted and seem more attractive to other people. And yet, our final goal is to find that without all of the make-up. What kind of twisted（扭曲的）game are we really playing with ourselves?
So I would like to make a suggestion for all women out there to give yourself a break at least this summer. Take a couple of pictures without all of that make-up on. You don’t need it every single day, especially not this hot summer! You’ll be surprised that the more confident you are about showing the real side of you, the more attractive you will be to everyone else.
Yes, the saying, “Beauty comes from within” is an old one, definitely still holds some troth today. So be brave, carefree, and make-up free! Let the world see you for who you really are!【语篇导读】本文是一篇议论文。文章论述了敢于以真面孔示人的女士才是自信的女人这一话题。

35. What is the topic of this text?
Of the many unpleasant emotions we can experience, fear may top the list. 36 . Fear can also keep us from pursuing the things in life that really matter—like following our dreams, and developing important relationships. I have some ideas, though, of how to be free from fear.
●Experience fear.I used to be very afraid of speaking in front of people. I would get sweaty palms and my stomach would be so tied up that I wouldn’t be able to eat. However, each time I spoke, I noticed afterwards that it wasn’t that bad. Things I fear are never as bad in reality as I make them out in my mind. 37 .
●Create space. The first and most important step to being fearless is to create some space between ourselves and the emotion of fear. This isn’t accomplished by ignoring the fear, or trying to talk ourselves out of it. 38 . In fact, a recent research shows that by simply admitting the emotion we actually begin to reverse the “fight or flight（逃避）” response in the body.
●Control the breath and feel the fear. Once we acknowledge the presence of fear, the second step is to control the breathing so that it becomes slower and gentler. We try to make the breath just a little bit longer, and feel how fear manifests（展现）in the body. 39 . With practice, we can create enough space between us and the emotion of fear so that we’re able to replace a fearful thought with a positive one. 40 . For instance, before I get up to speak in front of a group of people, I imagine that the audience is positively impressed by what I say and that I manage to complete the speech successfully.
A. We can imagine a positive outcome for whatever we’re about to do.
B. Space is created only when we can honestly acknowledge that fearexists.
C. Fear, if left uncontrolled, can even destroy our life.
D. As we pay attention to the physical symptoms of fear, we can see fearobjectively.
E. When we can see a positive outcome in our mind, fear no longer holdsus back.
F. But fear is more than just physically unpleasant.
G. So one way to get rid of fear is to simply push ourselves to dothings that we fear
36. A. We can imagine a positive outcome for whatever we’re about to do.
37. A. We can imagine a positive outcome for whatever we’re about to do.
38. A. We can imagine a positive outcome for whatever we’re about to do.

I used to think that it is hard to grow up into a responsible member of the society. An incident happening in a rainy Sunday afternoon changed my attitude. I was on my way to the bookstore and was waiting for the green light while a gift was knocked down by passing car, which drove off quickly. A man immediately gave her first aid and I had joined in without hesitation. Soon many help was given to the girl. Because we sent her to the nearest hospitals in time, she was able to receive properly treatment. Not badly injured, I expressed gratitude to those giving help. Compared with the escaping driver, I was proud of what I did.
A Leap（跳跃）to Honor
Leaping on a narrow balance beam（平衡木）is not easy. But Lola Walter, a 13-year-old gymnast, is an expert at it.
To perfect her skills, Lola for four hours a day, five days a week. At the state championships in March, she finished seventh out of 16 girls.
That’s especially impressive, she is legally blind, born with a rare condition that causes her eyes to shift constantly. She often sees double and can’t how far away things are.
When she was little, her mom that even though she couldn’t see , she was fearless. So her mom signed her up for gymnastics when she was three. She loved the right away and gymnastics became her favorite.
Though learning gymnastics has been more for her than for some of her tournaments, she has never quit. She doesn’t let her stop her from doing anything that she wants to.
She likes the determination it takes to do the sport. Her biggest is the balance beam. Because she has double vision, she often sees two beams. She must use her sense of touch to help her during her routine. Sometimes she even closes her eyes. “You have to your mind that it’ll take you where you want to go.“ says Lola.
To be a top-level gymnast, one must be brave. The beam is probably the most for anyone because it’s four inches wide. At the state competition, Lola didn’t fall the beam. In fact, she got an 8.1 out of 10 — her highest score yet.
Lola doesn’t want to be differently from the other girls on her team. At the competitions, the judges don’t know about her vision . She doesn’t tell them, because she doesn’t think they need to know. Her mom is amazed by her attitude.
Lola never thinks about She is presently at level 7 while the highest is level 10 in gymnastics. Her is to reach level 9. She says she wants to be a gymnastics coach to pass down what she’s learned to other kids she grew up
Lola is of all her hard work and success. She says it’s helped her overcome problems in her life outside gymnastics, too. Her for others is “just believe yourself”.
