Dick lived in England. One day in January he said to his wife, "I'm going to fly to New York next week because I've got some work there." "Where are you going to stay there?" his wife asked. "I don't know yet." Dick answered. "Please send me your address from there in a telegram (电报)," his wife said. "All right," Dick answered.

    He flew to New York on January 31st and found a nice hotel in the center of the city. He put his things in his room and then he sent his wife a telegram. He put the address of his hotel in it.

    In the evening he didn't have any work, so he went to a cinema. He came out at nine o'clock and said, "Now I'm going back to my hotel and have a nice dinner."

    He found a taxi (出租车) and the driver said, "Where do you want to go?" But Dick didn't remember the name and address of his hotel.

    "Which hotel are my things in?" he said, "And what am I going to do tonight?" But the driver of the taxi did not know. So Dick got out and went into a post office. There he sent his wife another telegram, and in it he wrote, "Please send me my address at this post office."

    While your pet fish may appear to be unaware of your presence, chances are that it knows you extremely well and can probably even identify you from a crowd of human faces!

    To test if this was accurate, some scientists decided to study archerfish（喷水鱼）. These animals don't have a sophisticated（复杂的）brain that is necessary to recognize the slight differences between human facial features.

    They began by presenting four archerfish with images of two human faces. Initially, the fish spit at both. However, they soon learned spitting water at the one selected by the researchers earned them a food treat. After that, they focused primarily on that image. The researchers then took the experiment one step further by introducing 44 other human faces to the mix.

    To the researcher's astonishment, the trained archerfish were able to recall the learned image almost 81% of the time. And this accuracy improved to 86% when the researchers made the identification even harder, by replacing the colored photos with a set of black and white images and hiding the shape of the head.

    The results of the study suggest that though having tiny brains, archerfish may have developed high visual discrimination abilities. While it is contrary to the previous theory that a sophisticated brain is necessary to recognize human faces, the researchers believe they do not recognize faces by recalling complex facial information like gender and identity, but more likely by discriminating between detailed  patterns. Even so, the fact that these archerfish could “remember” those faces demonstrates that they have an impressive memory for details that lasts much longer than the originally-thought 3 seconds!

    This is not the first time researchers have realized how “smart” fish are. Previous studies have shown that fish can recognize those fish they have “socialized” with previously, and even recall complex three-dimensional maps of their surroundings.

    Ways to make a great first impression

    You've heard it a million times already, but it really does take but a few seconds to make that all-important first impression (印象). Here are some easy ways for you to impress your classmates or teachers.

    {#blank#}1{#/blank#}

Before you shake hands with somebody, make sure that your hands are clean. The handshake should not be too strong or weak. Most people use their right hands, unless they have a reason to use the left.{#blank#}2{#/blank#}

    Be on time

    When meeting someone for the first time, arriving on time is as important as breathing. You may have an excuse, but that will leave the person who hardly knows you with a bad impression.{#blank#}3{#/blank#}It's better to be hanging around the place than be stuck in traffic.

    Introduce yourself and ask for names

    Make sure you properly introduce yourself. Ask for their name in a polite way.  {#blank#}4{#/blank#}This will increase the chances of their remembering your name in the future. Always remember to stand up when greeting someone and be sure to introduce them to anyone you're with.

    Make good conversation

To get the most out of your discussion, try to find something common between the two of you. {#blank#}5{#/blank#}A person will feel more comfortable with someone they can relate to (产生共鸣).

A. Use body language

B. Have a proper handshake

C. Repeat the name and use it later in conversation.

D. As a general rule, plan to arrive about 30 minutes early.

E. It could be a similar taste in clothes or a common hobby.

F. You'll be in serious trouble if you leave them with a bad impression.

G. However, don't have your left hand in your pocket because this appears impolite.

    With exams just around the corner, now is a good time to explore some of UCL's lesser-known study spaces and get down to some revision. Here are some good choices for you.

    UCL Senate House Hub

    UCL Senate House Hub opened in 2015 and provides 144 study spaces. What's more, you can check how many spaces are available online before you head to the hub! Located on the third floor of the South Block of Senate House, the center has room for individual and group study in traditional library spaces, as well as casual armchairs and bar-style desks.

    UCL Eastman Dental Library

    The newly refurbished(翻新的) UCL Eastman Dental Library is located halfway along Gray's Inn Road and is open from Monday to Friday, 9:00 am–8:00 pm. The library has 72 study spaces, and many IT facilities are available. The library also has a study room for meetings and a computer room with an interactive whiteboard.

    UCL Language & Speech Science Library

    UCL Language & Speech Science Library (Lass) has disabled access and has recently been refurbished to add extra study spaces. With only 49 spaces, Lass is smaller than most other UCL Libraries and tends to fill up relatively quickly, so get there early to avoid disappointment.

    Senate House Library

    This one may be cheating as the Senate House Library is not technically a UCL library. However, all UCL students and staff can register for free membership online. With millions of books and journals, Senate House Library offers some places a little less used by UCL students but perfect for getting down to some hard work.

    When a laptop or smartphone battery starts losing its power, the only options are to buy an expensive replacement, or just keep it plugged in all the time. But a woman Mya Le Thai may have found the answer to this problem.

    Thai was frustrated that the batteries for her wireless devices degraded(降级)over time, until they failed to charge fully. She did not like having to keep her laptop connected to an electrical outlet to keep it powered on. So, she decided to do something about that problem. At first, she and her team at UC Irvine thought about inventing a new battery. But as they experimented, Thai discovered something that might permit lithium—ion(锂离子)batteries to last forever.

    Lithium-ion batteries power most wireless devices. Over time, the batteries lose the ability to hold a charge. Most of these batteries have a life span of about 7,000 charging cycles before they die. One of the reasons lithium—ion batteries degrade is their use of nanowires to carry electricity. Nanowires are extremely thin. A human hair is thousands of times thicker, for example. Nanowires are extremely efficient carriers of electricity, which makes them useful in batteries.

    But, Thai had a theory—the nanowires might last longer if covered with a gel(凝胶). She and her team tested this theory. "It was a long process and a lot of work, "Thai said. The team tried many coverings for the wires. PMMA, a type of plastic, was one of them. The nanowires were coated with PMMA and cycled through charges 200, 000 times. The PMMA-coated nanowires showed no evidence of damage. The results suggest that batteries could last forever, without losing charging ability.

    Thai hopes to continue her research to understand why this gel works so well and to see if any other gel could create better results and she is enjoying the publicity about her discovery. She said she never expected her research to get media coverage. "It's kind of cool," she said. "I'm really glad people are showing interest in my work and not just in the work itself, but also in technology and energy."

Four things that you can't miss in Macao

    Go Bungee Jumping at the Macao Tower

    The Macao Tower, 338 meters tall, is the world's 10th highest tower, with kinds of activities, such as eating and entertainment. One of the activities is the bungee jump. The Macao Tower Bungee Jump is 233 meters high, making it a Guinness World Record as the highest commercial bungee jump in the world. Raise your arms and off you go! If you are not daring enough to jump that height, you can try the sky walk on the 57th floor—it's still amazing. Take this chance and tick off this item on your list.

    Enjoy a traditional Portuguese dinner

    Macao was once colonized (殖民) by Portugal before 1999. As a result, Portuguese culture has deeply affected Macao.

    Many Portuguese settled and opened Portuguese restaurants here, but it is more adaptable to Chinese people.

    Visit a museum

    Macao, as a little city with only an area of 30.5 square kilometers, has 23 eye-catching museums. Due to its special history, both eastern and western historical relics can be found. Many of them are preserved for cultural relics, tourist spots or museums, such as the Grand Prix Museum, Maritime Museum and Wine Museum.

    Go into an entertainment place

    Well known as the "Las Vegas of the Orient", Macao has 33 entertainment places. You can find different themed entertainment places with their hotels and attractions around every corner of Macao, especially on Taipa Island. Among all, The Venetian is the most popular. With a huge shopping mall and Vegas-style design, it is a must-go place for both tourists and locals to shop and enjoy free time. So when you come to Macao, just walk around and you will still be amazed.
