5、What is IRC? IRC is Internet Relay Chat. It is a group of networked server computers that let users connect and pass their messages among the networked servers in almost real time. In other words, it is a big chatting server, once you join a group, you are able to talk in an open forum (論壇)type environment or just one on one.
    What IRC Networks are out there? There are about fifty really mainstream IRC networks (groups of servers) you can connect to. The most common ones found are typically, ‘EF-Net’, ‘Under-Net’, and ‘DAL-Net’.
    What is a Channel? A channel is the name for the ‘group’ you are joining, or the ‘forum’ in which you want to talk. On IRC, channels are denoted (表示) as # Channel Name. For instance, say if you are interested in MP3 music, you may want to go to # MP3.
    How do I get on IRC? To get on IRC, you will need to get a client program. I personally suggest using ‘mIRC’, if you are in the windows environment. I have used the program for many years faithfully. It is a shareware（共享軟件）program that doesn’t disable after a given time period.
    What are the basic commands once I am on? Join # channel ― this will make you enter a channel. Part # channel ― this will make you exit a channel you are in. Nick new name ― this will change your current screen name.

A note as a warning about IRC. IRC is a wonderful forum for idea exchange, and a fun place to chat and learn. However you must keep in mind that you don’t know who is on the other end. That someone says they are 16 doesn’t mean they aren’t 45. Keep an eye on yourself and make sure not to give out any personal information on IRC before you know those on the other end of the line thoroughly. Attention! Safe IRCing everyone!

53. According to the passage, ‘EF-Net’, ‘Under-Net’, and ‘DAL-Net’ stand for ______.

A. chatting groups        B. group channels         C. computer massages    D. chatting networks

4、Each time a city building is set up, the grass in that spot and trees that once reached up to the sky are replaced by a tar(柏油) roof. In addition to that, roads, parking lots, and yet more buildings are being constructed. The total lost green space can have a very real effect on a city’s air temperature, air quality and energy costs. On a summer day in most American cities, a tar roof can feel like the inside of an oven (烤箱). But what if we could replace the hot roof of each skyscraper or building in a city with grass or a garden?
    Whether it holds vegetable gardens, wildflowers, or meadow grasses, a green roof can lower the temperature above a building by 60 degrees, which can reduce the building’s energy costs. If used more widely, green roofs could decrease a city’s total energy costs, reduce power plant emissions (排放), and improve air quality and public health. But that’s not all ― green roofs are a great way to deal with water management in urban areas with overwhelmed sewerage（排污）systems, and actually extend the life span (壽命) of the roof itself. And green roofs do something else: They beautify the city ― whether you’re on the 3rd floor or the 30th. Now that’s a great achievement.
    The environmental nonprofit group Earth Pledge is promoting a Green Roofs initiative (積極性). To learn more about how to create a green roof ― and the benefits it will provide ― visit its website at EarthPledge.com.

3、What’s your earliest childhood memory? Can you remember the first time you heard thunder or watched a television program? Adults seldom recall events much earlier than the year or so before entering school, just as children younger than three or four rarely keep any memory of specific, personal experiences.

   A variety of explanations have been put forward by psychologists for this “childhood amnesia” (記憶缺失). One argues that the hippocampus, the region of the brain which is responsible for forming memories, does not mature(成熟) until about the age of two. But the most popular theory thinks that, since adults do not think like children, they cannot access childhood memories. Adults think in words, and their life memories are like stories. But when they search through their mental files for early childhood memories to add to this verbal（文字的） life story, they don’t find any that fit the pattern. It’s like trying to find a Chinese word in an English dictionary.

   Now psychologist Annette Simms offers a new explanation for “childhood amnesia”. She argues that there simply aren’t any early childhood memories to recall. According to Dr. Simms , children need to learn to use someone else’s spoken description of their personal experiences in order to turn their own short-term, quickly forgotten impressions of these experiences into long-term memories. In other words, children hear others talk about their experiences--Mother talking about the afternoon spent looking for crabs (蟹) at the beach or Dad asking them about their day at Ocean Park. Without the help of this kind of verbal description, says Dr. Simms, children cannot form long-term memories of their personal experiences.

45. According to the passage, it is widely believed that ______.

A. it is impossible for an adult to recall his experiences

B. adults and children have different brain structures

C. adults think in words while children think in pictures

D. adults actually have no access to their childhood memories

A. a research center engaged in the study of human brains

B. a psychological research department of a university

C. a tiny campus formed in one’s childhood memory

D. a part of the brain in charge of the formation of memories

47. “Trying to find a Chinese word in an English dictionary” is stated to show that ______.

A. adults and children have different memory patterns

B. it is unlikely to find a Chinese word in an English dictionary

C. Chinese and English are totally different languages

D. memories are in some way connected with languages

48. According to Annette Simms, ______.

A. verbal support is necessary for children to have long-term memories

B. there does not exist such things as childhood memories

C. children’s brains are mature enough to form permanent memories

D. children are generally inexperienced and unable to remember things they don’t understand

2、Much older than the Great Wall, Stonehenge (巨石陣) is one of the world’s most fascinating, but least understood historical sites. Every year, thousands of tourists come to admire Stonehenge’s beauty and to wonder about how and why it was built.

Scientists have dated the site, which is located in England, to around 3000 BC. The stone circle was constructed in a number of stages over hundreds of years. It took millions of man hours to raise the heavy stones.

Though there are many theories, it is still a mystery how stone-age man dragged such heavy stones over 380 kilometers from where they were made. Prehistoric (史前) people had only basic wooden tools. To move the stones they probably used tree trunks to roll them along.

Some historians believe that Stonehenge was a temple, the site of ancient sacrifices (祭祀). Others believe it was a burial place or perhaps even a giant sundial (日冕) to tell the time. Whatever their ancient use was, the stones have always been a source of fascination for British people. One record from 1135 said the great stones were carried to England by giant magical creatures!

In modern times Stonehenge has become a huge hit with tourists.

1、Valentine’s Day was the time my father chose to show his love for the special people in his life. Over the years I fondly (天真地) thought    21     him as my “Valentine man”.

My first memory of the    22      he could bring to Valentine’s Day came when I was six. That morning at the breakfast table I found a card and a gift-wrapped package at my chair. The card was    23   “Love, Dad” and the gift was a ring with a small piece of red glass to    24    my birthstone, a ruby (紅寶石). There is     25     difference between red glass and rubies to a child of six, and I remember    26   that ring with pride that all the cards in the world     27     not surpass (超越).

  28   I grew older, the gifts gave    29   to heart-shaped boxes filled with my    30    chocolate and always included a     31    card signed “Love, Dad”. In those years my “thank-you” became   32    of a perfunctory (敷衍) response. The cards seemed less    33    , and I took for granted that the Valentine would     34    be there. I had    35     my hopes and dreams in receiving cards and gifts from “significant others” and “Love Dad” just didn’t seem quite    36    .

His final card remains on my desk today. It’s a     37    of how special fathers can be and how important it has been to me to know that I had a father who continued a  tradition of    38     with simple acts of understanding of the people in his life.

Those things never    39     , nor does the memory of a man who never     40    being my Valentine man.
