The gas has been a problem since people first began burning fuels to cook food or to create heat. It is a problem in all parts of the world that experience cold weather. Carbon monoxide is called the silent killer because people do not know it is in the air. The gas has no color1. It has no taste. It has no smell. It does not cause burning eyes. And it does not cause people to cough. But it is very deadly. It robs the body of its ability to use oxygen. Carbon monoxide decreases the ability of the blood to carry oxygen to body tissues. It does this by linking with the blood. When the gas links with the blood, the blood is no longer able to carry oxygen to the tissues that need it. Damage to the body can begin very quickly from large amounts of carbon monoxide. How quickly this happens depends on the length of time a person is breathing the gas and the amount of the gas he or she breathes in. Carbon monoxide poisoning has warning signs. But people have to be awake to recognize them. Small amounts of the gas will cause a person's head to hurt. He or she may begin to feel tired. The person may feel sick. The room may appear to be turning around. The person may have trouble thinking clearly. People develop severe head pain as the amount of gas continues to enter their blood. They will begin to feel very tired and sleepy. They may have terrible stomach pains. Medical experts say carbon monoxide affects people differently. For example, a small child will experience health problems or die much quicker than an adult will. The general health of the person or his or her age can also be important. An older adult with health problems may suffer the effects of carbon monoxide more quickly than a younger person with no health problems. People with heart disease may suffer chest pains. They may begin to have trouble breathing. Question: Why is carbon monoxide called the silent killer? - Because it tastes and smells good. - Because it is not easily noticed. - Because it kills and injures people. - Because it always harm people.[.
Because it is not easily noticed.

Read the following article and select the best answer. Article: My grandma whom we all called Nanny was a solid, first-generation, Italian immigrant. She came to this country with her family on a tiny ship during World War I when she was only 8 years old. During the trip she survived stormy seas,little food, and an attack by a German U-boat. After getting here,her large family worked hard to build a new life in America. They never had much money but were rich in love. One day,when I was about 5 or 6 years old, my parents and brothers went on a trip. It was just me and Nanny in the house for the weekend. Nanny seemed so happy to be taking care of me all by herself. She made me a special breakfast that first morning. However, all I could do was to complain about how the food was not how Mom always made it. Nanny quietly put down the plate and went into the living room. I followed a minute later and saw that she had tears in her eyes. It was the first time I had ever seen my strong and proud grandmother cry and I was the one who had caused it. I walked over to Nanny, climbed on her lap, and for the first time in my short life I did something else too. I apologized without being told to and asked Nanny to forgive me. She smiled, rubbed my head, and told me I was a good boy even though I didn't feel like one then. That memory just like my Nanny's love will stay in my heart forever. It is a sign of both strength and wisdom. Asking for forgiveness helps us to learn, to grow, and to love. Question: When seeing Nanny crying in the living room, the author felt _ . - surprised - ashamed - shocked - annoyed

Read the following article and select the best answer. Article: It is surprising that eating three meals a day--breakfast,lunch and dinner-has been a custom only since 1890. Before this time,people only had two meals a day--breakfast and dinner. In the 16th century,breakfast was only to break one's fast . But 200 years later it had become a large meal,not just for family,but for numbers of guests as well. It was a social event. It began at 10 a.m. and lasted until 1 p.m. Then breakfast began to be less popular. It became,instead,a lighter meal and was taken at a much earlier hour. By 1850 it had been pushed back to 8 a.m. and became a family meal. Dinner,however,went to the other way. In the 16th century it was eaten at 11 a.m. Years later,it had moved to the early afternoon,then to 5 p.m. By 1850 dinner time had reached 7 p.m. Lunch is a recent idea. It first appeared as a snack to fill the gap between breakfast and dinner. Question: The passage leads us to believe that _ . - our custom of meals is based on English custom - the body can adjust to two or three meals a day - breakfast is the most important meal for us - before 1890 people didn't eat three meals a day
before 1890 people didn't eat three meals a day
