Man's present efforts cannot prevent it .Time is bringing us more people, and more people will bring us more industry, more cars, larger cities and the growing use of man-made materials.

Q: Read the article and select the best answer. Article: The human body is a living machine, and, like all machines, it needs "fuel" to supply it with energy. This is provided by the food we eat. But how much do we need to stay healthy? The energy value of food is usually measured in calories . A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1degC. The number of calories people need per day is different, as the picture shows. Also, the number of calories you use at any one moment normally depends on the activity you are in. For example, you need more calories for standing than for sitting, more for running than for walking, and so on. The energy in food is in the form of three kinds of chemical materials--carbohydrate , protein and fat. Carbohydrate provides 3.8 Cal /gm of the energy, protein 4.0 Cal/gm, and fat 8.8 Cal/gm. Each food contains different amounts of these materials, as the round pictures show. (P= protein C= carbohydrate F=fat) Question: This passage mainly tells us _ . Options: A: all the energy is in food B: the human body needs energy C: the number of calories depends on your activity D: we must only eat peanuts to get calories
A: C

Q: Read the article and select the best answer. Article: Many college students have given up taking class notes by hand. Instead, they type on computers. But scientists say that method is less helpful. If you need to remember something, write it. Writing notes by hand is much better for long-term memory of idea. So, turn off your computer if you want to remember something. Students who type notes on a keyboard often write down what the teacher says word-for-word. They may write without really thinking about what they are writing. These electronic notes contained more words. But scientists say it leads to " _ ." Transcription means to write down something exactly as you hear it. However, students taking notes by writing them, need to first process the information they hear. Then they record just the main parts. They use fewer words. This is because people usually write slower than they type. This kind of process leads to a deeper understanding. The scientists did a research. In the research, students listened to a teacher and then took a test. Some took notes by typing on a computer. The others took notes by writing them down. Both groups performed about the same in remembering facts. But students who typed their notes did much worse on conceptual questions. These questions required them to understand an idea. Also, scientists found that those who wrote their notes remembered conceptual information better a week later. Scientists believe that the students who took notes by writing them had a deeper understanding of ideas. Scientists know that students probably will still use their computers in class. But they suggest to take notes by hand on screens. They say this might be a good way between different schools. Question: According to the research, college students usually use few words to take notes by hand in class because they _ . Options: A: are very lazy B: want to write fast C: are all clever D: dislike to take notes
A: B
