Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the questionSome doctors think that you should drink a glass of water each morning. You should drink this water first thing, before doing anything else. The temperature of the water should be similar to body temperature; neither too hot nor too cold.Why should you drink this water? Water helps your body in many ways. It helps clean out your kidneys. It prepares your stomach for digestion. Water can also help your intestines work better. After drinking water, the intestines can more easily take out nutrients from our food. Water also helps us go to the bathroom more easily.Scientists suggest that people take in 1,600 milliliters of water each day. But don’t drink all of that water in one sitting. If you do, your kidneys will have to work much harder to eliminate it. It’s better to drink some in the morning and some in the afternoon. Some people think it’s better to drink between meals and not during meals. They think water dilutes the juices produced in our stomachs. This can interfere with normal digestion.Are you drinking enough water every day? Check the color of your urine. If it is light yellow, you are probably drinking enough. If your urine is very dark yellow, you probably need to drink more water. A little more water each day could make you much healthier.(Adapted from Reading Challenge 1 by Casey Malarcher and Andrea Janzen)According to the passage, water is good for the following organs of the body, EXCEPT ________.

If boring and repetitive factory work could be (27) _______ by robots, why not boring and repetitive household chores too?For a long time the only people who really gave the problem their attention were amateur inventors. And they came up against a major difficulty. That is, housework is actually very complex. It has never been one job, it has always been many. A factory robot (28) _______ one task endlessly until it is reprogrammed to do something else. It doesn’t run the whole factory. A housework robot, on the other hand, has to do (29) _______ different types of cleaning and carrying jobs and also has to cope with all the different shapes and positions of rooms, furniture, ornaments, cats and dogs. (30) _______, there have been some developments recently. Sensors are available to help the robot locate objects and avoid obstacles. We have the technology to produce the hardware. All that is missing the software- the programs that will operate the machine.Điền vào ô số 30

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 35 to 42 Many ants forage across the countryside in large numbers and undertake mass migrations; these activities proceed because one ant lays a trail on the ground for the others to follow. As a worker ant returns home after finding a source of food, it marks the route by intermittently touching its stinger to the ground and depositing a tiny amount of trail pheromone – a mixture of chemicals that delivers diverse messages as the context changes. These trails incorporate no directional information and may be followed by other ants in either direction. Unlike some other messages, such as the one arising from a dead ant, a food trail has to be kept secret from members of other species. It is not surprising then that ant species use a wide variety of compounds as trail pheromones. Ants can be extremely sensitive to these signals. Investigators working with the trail pheromone of the leafcutter ant Atta Texana calculated that one milligram of this substance would suffice to lead a column of ants three times around Earth. The vapor of the evaporating pheromone over the trail guides an ant along the way, and the ant detects this signal with receptors in its antennae. A trail pheromone will evaporate to furnish the highest concentration of vapor right over the trail, in what is called a vapor space. In following the trail, the ant moves to the right and left, oscillating from side to side across the line of the trail itself, bringing first one and then the other antenna into the vapor space. As the ant moves to the right, its left antenna arrives in the vapor space. The signal it receives causes it to swing to the left, and the ant then pursues this new course until its right antenna reaches the vapor space. It then swings back to the right, and so weaves back and forth down the trailAccording to the passage, the highest amount of pheromone vapor is found _____

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 30 to 34 Martin Luther King, Jf., is well- known for his work in civil rights and for his many famous speeches, among which is his moving “I have a dream” speech. But fewer people know much about King’s childhood. M.L., as he was called, was born in 1929 in Atlanta, Georgia, at the home of his maternal grandfather. M.L.’s grandfather purchased their home on Auburn Avenue in 1909, twenty years before M.L was born. His grandfather allowed the house to be used as a meeting place for a number of organizations dedicated to the education and social advancement of blacks. M.L. grew up in the atmosphere, with his home being used as a community gathering place, and was no doubt influenced by it. M.L.’s childhood was not especially eventfully. His father was a minister and his mother was a musician. He was the second of three children, and he attended all black schools in a black neighborhood. The neighborhood was not poor, however. Auburn Avenue was an area of banks, insurance companies, builders, jewelers, tailors, doctors, lawyers, and other businesses and services. Even in the face of Atlanta’s segregation, the district thrived. Dr. King never forgot the community spirit he had known as a child, nor did he forget the racial prejudice that was a huge barrier keeping black Atlantans from mingling with whitesWhich of the following statements is NOT true?
