One day, I heard an American boy say to a Chinese girl student, “You speak very good English.” But the girl answered, “No, no. My English is very poor.” The foreigner was quite 1 at the answer. Thinking he had not made 2 understood or the girl had not 3 him clearly, he said, “Yes, indeed, you speak very well.” 4 the girl still kept saying, “No.” In the end the American boy could not understand and didn’t know 5 to say. What’s wrong with the girl’s answer? She didn’t 6 a compliment (恭维) in the same way as the American people do. She should answer, “Thank you” instead of “No”. She 7 understood what the American boy had said, but she thought she should be modest. In the 8 , people will feel proud and 9 when they are praised . So if someone says the 10 you have cooked are very delicious, you should say, “Thank you.” In our country we think being modest is a virtue (美德) and being proud is a bad thing , but in my opinion, being confident does not 11 being proud, so sometimes you should be confident 12 being modest. 13 you are modest and say, “No, I’m afraid I can’t do it well”, while working in a western country, the others may think that you really cannot do it. If you often say “No”, you will certainly be looked down upon by 14 . When asking for a job, if one says something like “Yes, I can certainly do it” instead of “Let me have a try”, he or she will 15 get it. So in the west, you should be brave to show your self-confidence.

In early 2004 eight tiny sensors were dropped from a plane near a military base in California. After hitting the ground, the sensors—also known as smart dust sensors—organized themselves into a network and quickly detected a fleet of military vehicles on the ground. They determined the direction, speed and size of a series of military vehicles traveling along the road and later transmitted the data to a computer at a nearby base camp.
Smart dust sens6rs are minicomputers—as small as a grain of rice in some cases—that can monitor and evaluate their physical environment and can relay the information via wireless communication. They can monitor elements such as temperature, moisture, humidity, pressure, energy use, vibration, light, motion, radiation, gas, and chemicals. These devices will soon have many applications, such as use in emergency rescue.
Software has been developed to run these minicomputers. A key feature of the software is the ability of the sensors to automatically organize themselves into a communications network and talk to each other via wireless radio signals. If any one connection is interrupted, the sensors will self-correct and pass the information on to the next available sensor.
Each sensor has a chip that does the computing work—recording things like temperature and motion at its location. Each sensor also has a tiny radio transmitter that allows it to talk to other sensors within 100 feet or so. With a single network of 10,000 sensors—thought to be the biggest array (排列) of sensors currently possible—you could cover 9 square miles and get information about each point along the way. The data finally works its way to a base station that can send the information to a computer or to a wireless network.
The scientists who are working with this technology say smart dust sensors can be used to detect the location or movement of enemy troops in areas too dangerous or remote for soldiers to operate. Scattering hundreds of self-networking sensors from a manned or unmanned plane onto the battlefield, in theory, could produce critical information and lead to strategic advantage. Sensors could also be used to detect the presence of chemical weapons and could give troops the time needed to put on protective gear.
The passage implies that the smart Just sensors are most likely to be used in ().
A. emergency rescue
B. monitoring pollution
C. military operations
D. evaluating the environment
