- sleepy
- anxious
- hungry Now, answer this question: Read the following article and answer the question. Article: We can express our feelings and needs by using body language. Cats can do that too. The ways that cats use their tails to show their feelings and needs are interesting. Unlike dogs, which generally wave their tails to express good feelings, cats use their tails to send a lot of signals. When a cat waves its tail strongly from side to side, it may be a sign for us to leave it alone, or we may get scrathed . Throwing a little toy for the cat to play with can get it relaxed. When a cat holds its tail upwards with a slight move, it means the animal is very happy to see its owner. We all like to cuddle inside our bed, and cats do that thing, too. Much as little children like to wrap (......) their arms around their Teddy Bears, cats like to wrap their own tails around their bodies to get a sense of safety while asleep. If we notice a cat sleeping in such a position, we should not break its peace. Usually the tip of the cat's tail doesn't draw our attention. But its particular position may also show the cat's feelings. For example, a cat holding the tip of its tail pointed downwards may try to say that it is not feeling comfortable. So at this point, the cat not only feels angry, but also unsafe. This may again be a sign for us not to upset the cat in any way. In conclusion, cats use their tails in many different, sometimes funny ways to send us messages, and we can learn to know more.

- The gate on the north.
- The gate on the south.
- The gate on the east.
- The gate on the west. Now, answer this question: Read the following article and answer the question. Article: The ancient city is in Pingyao county, Shanxi Province. The city wall was first built during the Zhou Dynasty. Since 1997, it has been listed as a World Heritage Site. Now Pingyao city is the only one in China completely protected as it was hundreds of years ago. The perimeter of this square city is 6.4km long and the city wall is the earliest and largest city wall in China. It is 12 m high with width of 5 m. The wall was built with earth and covered with bricks. Outside the city wall there is a river, 4 m wide and 4 m deep. There are several gates of the city, two each on the east and west and one each on the south and north side. All the gates have two doors each. This has given the city the name "Turtle City" with the two gates on the south and north standing for the head and tail of the turtle and four gates on the east and west as the four legs. The doors on the south and north stand opposite each other, like the head of the turtle extending out and two wells just beyond southern gate are like a turtle's two eyes. Located on the trade route between Beijing and Xi'an, Pingyao developed into a merchant center where the local people set up the nation's earliest banks. These banks were the first in China to use checks. Several old courtyards have been turned into museums, most of which were homes and offices of Pingyao's old banks. One of the most unusual aspects of a visit here is realizing that this place was very important to China's financial history. Question: Which gate in Pingyao city stands for the head of the turtle? Answer:
A:
output: The gate on the south.

- How to detect nuclear radiation.
- How radiation kill a man.
- The mystery about nuclear radiation.
- Serious damage caused by nuclear radiation. Now, answer this question: Read the following article and answer the question. Article: Nuclear power's danger to health, safety, and even life itself can be summed up in one word: radiation. Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can't detect them, sense them, without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things. At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no levels of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and if they are killed immediately. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They can grow into cancer. Sometimes this does not show up for many years. This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorbed by its grandparents. Radiation can hurt us. We must know the truth. Question: What is the main idea of the passage? Answer:
A:
output:
The mystery about nuclear radiation.
