Read the following article and select the best answer. Article: When I first entered high school, I knew no one at my school. All my friends in middle school went to other schools. I wanted to make some new friends. However, I was shy and wasn't good at making new friends. On my first day at school, I looked at others who were talking in groups happily. How I wish I were one of them! I guess I was very lucky then. At lunch in the dinning hall, when I was eating at a table alone, a girl came to me. "Excuse me, is this seat taken?" she asked. I immediately shook my head. She smiled and sat down opposite to me. I felt a little _ and didn't know what to say at all, but I really wanted to communicate with her. It was a good opportunity to make friends with her. When I looked up, I found she was smiling at me. Her smile calmed me down. "I really like this school. It's beautiful, but I don't know anyone here. All my friends went to other schools," said the girl. Hearing her words, I immediately said, "my friends are not here either. Can we be friends?" I was surprised. I couldn't believe I would say something like that, and to my surprise, that girl immediately said "yes". We both smiled. We became very good friends. Now it's the beginning of a new term again. Many students may have no friends at their new schools. If you are also as shy as I used to be, please don't be afraid to talk to others. You may get a surprise and make a new friend. After all, others want to make new friends, too. Question: We know on her first day at school, the author _ . - hoped she could make some new friends - only knew a few people at her school - met some old friends at her new school - hoped she could go to her old friends' schools

Q: Read the following article and select the best answer. Article: There is a very special wolf that lives in Africa. They are actually called, the African wild dog, of painted dogs. These animals live in open woodlands, or in the plains of Africa. Today, however, most of the animals can be found in eastern or southern Africa. These animals are beautiful. They have rounded ears instead of pointed like most dogs, and they have four toes on each of their four feet, also a unique characteristic because other dogs have five. Their fine fur is always different from each other. The fur is usually a combination of black, brown, red, and white, and sometimes even yellow. No wonder they're called the painted wolf. The African wild dog is a very social animal. They live in groups and have numbers from five to about twenty. The members of a group are always very close to one another. They communicate in their own language or body language. When someone is very old or sick, the others will help, and they are willing to share the food with the elders and with those who are weak, which is what we should learn from. The family does everything together, from raising young, to sleeping together, to hunting. When they hunt, they will work together suing team work to kill animals that are larger than them. They sometimes hunt farm animals. This is unfortunate, because both poachers , and people who own farms shoot the painted dogs who are just trying to survive. Before, there used to be many large groups throughout the land, but now the African wild god is very rare. They are also losing their population because of their own loss of habitat thanks to human's farming and forest cutting. Question: Why do African wild dogs get the name "painted dogs"? - They all have colorful fur. - The dogs in the same group are of different colors. - Artists love to paint them in different colors. - None of them has the same color.
A: They all have colorful fur.

Read the following article and select the best answer. Article: Beyond two or three days, the world's best weather forecasts are doubtful, and beyond six or seven they are worthless. The Butterfly Effect is the reason. For small pieces of weather--to a global forecaster, small can mean thunderstorms and blizzards --any prediction becomes worse rapidly. Errors and uncertainties increase, from dust devils and storms up to continent-size eddies that only satellites can see. The modern weather models work with net-like points sixty miles apart, and even so, some starting data have to be guessed, since ground stations and satellites cannot see everywhere. But suppose the earth could be covered with sensors placed one foot apart, rising at one-foot intervals all the way to the top of the atmosphere. Suppose every sensor gives perfectly accurate readings of temperature, pressure, humidity , and any other data a weatherman would want. Exactly at noon a powerful computer takes all the data and calculates what will happen at each point at 12.01, then 12.02, then 12.03... the computer will still be unable to predict whether Princeton will have sun or rain one month away. At noon the spaces between the sensors will hide fluctuations that the computer will not know about. By 12.01, those fluctuations will already have created small errors one foot away. Soon the errors will have added to the ten-foot scale, and so on up to the size of the globe. Question: A weather forecast _ in the world. - is reliable within one or two days - is doubtful beyond 24 hours - becomes useless beyond two or three days - is still worthwhile in seven days
is reliable within one or two days
