- The Greenhouse Effect
Q: Read the following article and answer the question. Article: The earth is 4 600 million years old. We humans have lived on earth for only 35 000 years, but during this period we have changed our planet a lot in many ways. Some things we've done are very good for the earth while some are bad. All over the world, people have cut down millions of trees. When it rains or when the wind blows, the earth is taken away. Forests have become deserts, so more and more sorts of animals and plants are disappearing. In big cities, cars and buses have polluted the air. Many people in cities now have health problems. Factories have also polluted the land and the water. As a result, many rivers and lakes are now dead. Around the earth, there's a special kind of oxygen called "ozone"(O3). It is important to the earth. But now air pollution is destroying it and that has made a very big hole in the ozone layer. Too much harmful radiation from the sun passes through the hole and reaches the earth directly. This is very dangerous because this kind of radiation can cause cancer. Carbon dioxide (CO2) in the air has increased a lot. It mainly comes from burning oil, coal and wood. This has formed a "blanket" around the earth. The heat from the sun can't escape so the temperature is rising. This is called "the greenhouse effect". It causes the level of the oceans to rise and the climate of the earth to change. All these problems are very serious, so we must do something now. ,A, B, C, D. Question: What is the best title for this passage? Answer:
Answer: Environmental Problems

Problem:OPTIONS:
- ORBIS didn't do its best to offer help
- there is no good medical knowledge and skills
- some countries can't afford medical knowledge and skills
- developing countries don't pay much attention to the blind

Read the following article and answer the question. Article: Close your eyes for a minute and imagine what life would be like if you couldn't see. Imagine having to read this page, not with your eyes but with your fingers. How do you feel, then? With medical knowledge and skills today, two-thirds of the world's 42 million blind people should not have to suffer. Unluckily, rich countries have this knowledge, but developing countries do not. ORBIS is an international charitable organization. Its goal is to help fight blindness all over the world. Inside a DC-8 airplane, there is a teaching hospital with television room and classroom. Doctors are taught the latest technology of helping the blind get sight again here. ORBIS is always trying to keep a closer relation among countries. ORBIS helps those developing countries by providing sight-saving training. It has taught over 35,000 doctors and nurses. They continue to treat thousands of blind people every year. They have traveled around the earth 3 times, visited 76 countries and treated over 20,000 blind people. They need your help to continue their work and free people from blindness. For just $ 38, you can help one person see; for $ 380 10 people can see; $ 1,300 helps train a doctor new skills; and for $ 13,000 you can provide a training program for a group of doctors who can make thousands of blind people see again. Your love can help them open their eyes to the world. Question: A lot of blind people in the world have to suffer because _ . Answer:
****
A: some countries can't afford medical knowledge and skills

Read the following article and answer the question. Article: It is easy for us to tell who our family members are, but do plants recognize their own family? Some do, scientists say, according to a report by Science News in early 2010. Guillermo P. Murphy and Susan Dudley are two plant scientists from McMaster University in Hamilton, Canada. They did a few experiments with Jewelweeds, a kind of flower that grows in wet, shady spots. They found that the flowers seem to know their own flower family. In their experiments, Murphy and Dudley planted jewelweeds in pots with either _ or strangers. When jewelweeds were planted in pots with strangers, the plants started to grow more leaves than if they had been planted alone. This response suggests that plants are competing with strangers for sunlight, since a plant with more leaves can receive more light and make more food. Jewelweeds usually grow in the shade, where sunlight is not enough. When jewelweed seedlings were planted with siblings, they grew a few more branches than they usually would if they were alone - but they did not start growing lots of extra leaves. This behavior suggests the plants are more likely to share resources, rather than compete. According to the Science News report, Jewelweeds are not the first plants that plant scientists have studied for family recognition. In 2007, Dudley and her team studied the Great Lakes sea rocket, a plant that grows on the beach - where it may be hard to get fresh water. In that experiment, the scientists found that when sea rockets were planted with siblings, they tolerated each other. But when they were planted with strangers, the sea rockets reacted by working extra hard to grow lots of roots. Dudley says this just because sea rockets, on the beach, get plenty of sun but struggle for water - so when they're threatened, they compete for water. Jewelweeds have plenty of water but have to compete for sunshine, so they grow more leaves. Question: In the text, the writer mentioned the experiments of Jewelweeds to _ . Answer:
OPTIONS:
- make a comparison
- introduce a topic
- describe a pretty flower
- build a new theory
introduce a topic

Read the following article and answer the question. Article: We all know that every class has its own rules, like "No smoking!", "No eating!" and "No sleeping!". Our class used to be noisy, because some students were talking when a student was answering the teacher's questions. So our head teacher made some class rules. In class, we should observe the rules. Now, I list some rules in our class: 1. No talking when Someone is speaking. 2. No sleeping in class. 3. No eating in class. 4. Students can't arrive late for school. Be always on time. 5. No playing in class. 6. No laughing when someone makes a mistake. 7. No smoking or drinking. 8. Students can't dye hair. Boys can't let their hair grow too long. 9. In the schoolyard , students can't ride bikes. 10. Students can't fight with each other. Maybe some students don't obey some of the rules. They may smoke, fight and dye hair. But most students think the rules are fine and say they will obey the rules. I think because our class has such rules, we will study better and better. Question: The students should go to school _ .
