Cats have a pair of vomeronasal organs(犁鼻器) on the roof of the mouth. When the cat wants to sniff, she will breathe the air in through her mouth. At this moment, she will often squint(斜视) her eyes and maybe even flatten(使…平坦) her ears. This makes her look like she is making faces. The vomeronasal organs will then analyze the smell---almost as if the cat is tasting the smell.
When you come home from outside the house, your cat can smell what you had for lunch and for a mid-afternoon snack. She can smell the people you shook hands with and your neighbour you stopped to talk to and hug. She can smell the grass brought under your shoes as you took a shortcut across the lawn. Your cat’s sense of smell is so good that she can smell difference between a gallon of water with a teaspoon of salt in it and plain water. In comparison, we think of salt as completely tasteless.
Cats have scent glands(臭腺) on each side of the forehead, on the chin, the lips and next to the tail. When your cat rubs up against your hand, your leg, the sofa, and your bed, she is leaving her scent in those things. She will then use her sense of smell to recognize “her” things, people and even other pets in the home.
If you want to have fun with your cat’s sense of smell, take some small bits of different things, such as a bit of chicken, some flowers and some fish. Place each different scent under a piece of paper towel(so your cat cannot see any of them) and encourage your cat to investigate and find what kind of food she likes to eat best.

查看习题详情和答案>>You will have a lot of reading to do in this grade this year. You can do more of it in less time if you learn to read rapidly.
Perhaps you have been told about some habits
（习惯）which keep a person from reading fast and have been strongly asked to break those habits which you might have.Do you still have any of these bad habits? Check yourself by answering
“yes”or“no”to these questions.(1) Do you move your lips
（嘴唇）when reading silently?(2) Do you point to words with your finger as you read?
(3) Do you move your head from side to side as you read?
(4) Do you read one word at a time?
If you answer
“yes”to any of these questions, start at once to break the habit. If you move your lips, hold your fingers over them, or hold a piece of paper between your lips while you are reading. Then if your lips move, your will know it and can stop them.If you point to words, hold the two sides of your book, one side with your left hand, the other side with your right hand. Then you won't have a free finger to use in pointing while reading. If you move your head, place your chin
（下巴）in one hand and hold your head still（静止不动的）.If you read no more than one or two or three words at a time, you need to work very hard in learning to take in
（吸收）more words at each glance（一瞥）as your eyes travel across the lines of words.Even if you do rather fast now, you can learn to read even faster. As you probably have been told, the secret of fast reading is to take in whole groups of words as each glance. Read in through groups and force
（迫使）your eyes along the lines of words as fast as you can to make them go. Anyone who practices doing these things will be able to read faster.(1)You may hold your fingers over your lips while reading so as __________.
