Read the following article and answer the question. Article: One day I heard that one of my dear friends had lost his mother. This made me sad, for my friend was very close to his mother. He had been by her side as she traveled through her long and hard journey with cancer. At this time, many memories about my loved ones that had passed away came flooding to me. Finally these memories passed, but it was really sad to think that my friend would have to go through the pain. Three times I tried to write an email to my friend and three times words failed me. I am a person who is not often lost for words and I decided to have a sleep. Upon waking up I could hardly wait for my computer to work, the words I needed were there. I was still left with a heavy heart although I had sent an email. They say that everything in this universe is balanced and indeed it is. Three days later, I received his reply letter. I was happy to hear that he'd been admitted to Cambridge University. It served as a gentle reminder for me that my friend would be okay and that life would go on. Everything in life is balanced; the lowest feelings change places with the highest feelings. Without the lows, we would never appreciate the highs. No matter how dark the clouds seem to be, the sunshine is always there and just waiting for the opportunity to shine through. Question: The author aims to tell us that _ . Answer:

Read the following article and answer the question. Article: Dear SJ, Losing a best friend is never easy. Your problem, is not just that you miss your best friend, it is that you feel empty and lost without her friendship. It takes time to get over a lost, and during that time, your mind is getting used to _ . This is usually a good thing, even if it feels like a bad thing. Now that you are on your own, you are being forced to learn to be by yourself and to rely upon your own inner voice for guidance. I am sure that this feels strange for you, but if you can hang on for a bit longer, it may work to your advantage. Best friends are cool, but it is important to know the difference between missing someone and being too independent upon them. At your age, girls do tend to stick together and having a good boyfriend may not yet be the better choice. Your friend is leaving you, her best friend, for a boyfriend. Boyfriends are completely different from best friends. The distinction is that boyfriends come and go, while girl friends often stay in your life throughout high school, and even afterwards. It is a completely different sort of bond. I suggest that you take advantage of this period in your life to expand your horizons. Enjoy the freedom of having no best friend for a while, and hang with the group. By the time your former best friend breaks up with her boyfriend, you will be in a completely different place, a far better place. And, by the way, next time you feel empty and lost, try to write about it in a diary. In several months, you will look back and read it with curiosity about yourself. "Who was I then, and what could I have been thinking?" Question: The writer believes by the time SJ's former friend loses her boyfriend, SJ will _ . Answer:
OPTIONS:
- take revenge on her former friend
- comfort her former friend
- feel more independent and confident
- continue friendship with her former friend

Answer: feel more independent and confident

Read the following article and answer the question. Article: As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. The they become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (, ) in science. Scientists spend their lives trying to find out about the world. Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry . These scientists have already discovered a lot about our world. For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute. Of course, scientists cannot answer all of our questions. If we ask, "Why does the ocean water taste salty?" Scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , "What happens to the salt in the ocean? The ocean does not get saltier every year." Scientists are not sure about the answer to this question. We know a lot about our world, but there are still many answers that...
