     If you and your friends wish to share a secret, you can write it in code (编码), and no one else will be
able to read it.
     Codes are one way of writing in secret. Ciphers (暗码) are another. In a code each word is written as a
secret code word or code number. In a cipher each letter is changed. Codes and ciphers have played an
important role in the history of the world. Julius Caesar, the Roman ruler who defeated almost all the countries
in Europe about 2, 000 years ago, used a cipher when he sent secret messages to his troops. During the
American Revolution, George Washington"s spies used a kind of code to send him information about the enemy
before his military (军事的) action. In World War Ⅱ, the Americans "broke", or figured out, Japan"s most
important navy codes and got enough information to destroy a powerful Japanese fleet( 舰队).
     Storekeepers use codes to mark their goods. The codes show how much was paid for the goods or when
 they were added to the stock (商品). Businessmen use codes to hide plans from their business enemies.
Sometimes personal letters or diaries are written in code. Many people enjoy figuring out codes and ciphers
simply as a hobby.
     In the 16th century, codes and ciphers were very popular among scientists. They wrote messages to each
other in code so that no one else would learn their secrets. Geronimo Gardano, an Italian astrologer (星相家),
mathematician, and doctor, invented the trellis cipher. He took two sheets of paper and cut exactly the same
holes in each one. Then he sent one sheet, which he called a trellis, to a friend and kept the other for himself.
Whenever he wanted to write a message, he put his trellis over a clean sheet of paper and wrote the secret
message through the holes. Then he removed the trellis and filled the rest of the paper with words that would
make sense. When his friend received it, he put his trellis over the writing and read the secret message.

1. The best title of this passage would be _______. A. Codes and Ciphers
B. Differences between Codes and Ciphers
C. History of Codes and Ciphers
D. Inventors of Codes and Ciphers 2. Which of the following statements is true?A. Ciphers can be broken or figured out more easily than codes.
B. You could read some words in Geronimo"s letter without his trellis.
C. The first person who ever used a cipher in history was Julius Caesar.
D. Fondness of using codes was the hobby of the scientists in the 16th century. 3. According to Geronimo Cardano, a trellis is _______. A. a piece of paper with many small holes
B. a secret message with a lot of small holes
C. a letter with unreadable words and sentences
D. a sheet of paper with groups of Arabic figures4. It is NOT mentioned in the passage that codes and ciphers are used for the purpose of _______. A. military affairs           
B. commercial secrets
C. scientific achievements

阅读理解。     When I was eight, I saw a movie about an island that had an erupting volcano and jungles filled with wild
animals. The island was ruled by a beautiful woman called Tondalaya, the Fire Goddess of the Volcano. It was
a low budget movie, but to me, it represented the perfect life. But through the years, Tondalaya was forgotten.
     The week I turned 50, my marriage came to a sudden end. My house, furniture and everything I"d owned
was sold to pay debts that I didn"t even know existed. In a week I had lost my husband, my home and my
parents who had refused to accept a divorce (离婚) in the family. I"d lost everything except my four teenage
children. I used every penny I had to buy five plane tickets from Missouri to Hawaii. Everyone said I was
crazy to think I could just run off to an island and survive. I was afraid they were right.
     I worked 18 hours a day and lost 30 pounds because I lived on one meal a day. One night as I walked alone
on the beach, I saw the red orange lava (火山岩) pouring out of Kilauea Volcano in the distance. It was time to
live my imagination!
     The next day, I quit my job, bought some art supplies and began doing what I"loved. I hadn"t painted a
picture in 15 years. I wondered if I could still paint. My hands trembled the first time I picked up a brush. But
before an hour had passed, I was lost in the colors spreading across the canvas (画布) in front of me. And as
soon as I started believing in myself, other people started believing in me, too. The first painting sold for $1 500. 
     The past six years have been filled with adventures. My children and I have gone swimming with dolphins,
watched whales and hiked around the crater rim (火山口边缘) of the volcano. We wake up every morning
with the ocean in front of us and the volcano behind us. The dream I had more than 40 years ago is now reality.
I"m living freely and happily ever after. 1. Why did the writer go to Hawaii? A. To make a living.
B. To spend her holiday.
C. To free herself from trouble.
D. To realize her childhood dream. 2. Which of the following is the writer"s dream? A. Get close to wildlife.
B. Live a free and happy life.
C. Live in nature with animals.
D. Become a successful painter. 3. We can infer from the passage that _____. A. the writer had never done painting before
B. the writer"s parents encouraged her to divorce
C. the writer"s husband took away most of her money
D. the writer wasn"t sure whether she could survive in Hawaii at first

阅读理解。     How do you know if your home is an easy aim for thefts (偷窃)? Around the holidays, many families don"t
consider taking proper measures to prevent their homes from suffering holiday thefts. With just a few simple
steps, you can better make sure of the safety of your home during all of the holiday celebrations. Here are a
few tips for making it difficult to tell you are away from home. 
     ● Either have a trusted neighbor pick up your mail and newspapers, or tell your mailperson to hold your
mail until you return. Nothing says "Hey, we are not home!" like when your postbox is filled with all kinds of
mails and you have many different newspapers in your driveway. 
     ● Set several different lights in your house on random timers (随机定时器). Don"t leave your outdoor lights
on all the time. Instead, put your outside lights on timers to be on during the nights. If an outdoor light remains
on for days at a time, it means that nobody is home to turn it off. 
     ● If you have pets that you are not taking with you on vacation, leave them with a friend, rather than having
someone come into your house every day to take care of them. When thefts see a neighbor or friend entering
your house every day, they will know you are not home. 
     ● Close all your curtains when you leave town. This is effective to deter possible thefts, as no one can see
what is in your house. If they don"t know what there is to take, then the risk is even greater for them to break
in. 
     ● This article just has suggested a few tips to help you keep your house safe while you are on holiday.
Nothing can truly protect your home unless you have it monitored by a professional home security system. 1. What is the main idea of the passage? A. to tell us how to prevent the thefts around the holidays.
B. to let the outdoor lights on all the time.
C. to tell us many families suffering from the thefts while they are on holiday.
D. to tell you to have your neighbor go to your house to take care of your pet. 2. If you are on holiday in other places, the lights in your house should _____. A. be lit in an irregular way
B. be kept on all the night

Radio
     Most teenagers nowadays are not regular listeners to radio. They may occasionally tune in, but they
do not try to listen to a program specifically. The main reason teenagers listen to the radio is for music,
but now with online sites streaming music for free they do not bother, and users can choose the songs
they want instead of listening to what the radio presenter/DJ chooses.

Television
     Most teenagers watch television, but usually there are points in the year where they watch more than
average. This is due to programs coming on in seasons, so they will watch a particular show at a certain
time (as long as it lasts) but then they may watch no television for weeks.
     Teenagers are also watching less television because of services such as BBC iPlayer, which allows
them to watch shows when they want. Whilst watching TV, adverts come on quite regularly (18 minutes
of every hour) and teenagers do not want to watch these, so they switch to another channel, or do
something else whilst the adverts run.

Newspapers
     No teenager that I know of regularly reads a newspaper, as most do not have the time and cannot be
bothered to read pages and pages of text while they could watch the news summarized on the Internet or
on TV.

Internet
     Every teenager has some access to the Internet, be it at school or home. Home use is mainly used for
fun (such as social networking) whilst school (or library) use is for work. Most teenagers are heavily
active on a combination of social networking sites. Facebook is the most common, with nearly everyone
with an Internet connection registered and visiting>4 times week. Facebook is popular as one can interact
with friends on a wide scale.
     For searching the web, Google is the dominant figure, simply because it is well known and easy to
use. Some teenagers make purchases on the Internet (on sites like eBay) but this is only used by a small
percentage, as a credit card is required and most teenagers do not have credit cards. Many teenagers use
YouTube to watch videos (usually anime which cannot be watched anywhere else) and some use it as a
music player by having a video with the music they want to listen to playing in the background.

Mobile Phones
     99pc of teenagers have a mobile phone and most are quite capable phones. Usually, teenagers only use
their phones for texting, calling. Features such as video messaging or video calling are not used-because
they are expensive.
     Services such as instant messaging are used, but not by everyone. It usually depends, whether the
phone is Wi-Fi compatible, because otherwise it is very expensive to get Internet off the phone network.
As most teenagers" phones have Bluetooth support, and Bluetooth is free, they utilize this feature often.
     Mobile email is not used as teenagers have no need; they do not need to be connected to their inbox
all the time as they don"t receive important emails.
