【题目】Keeping pet dogs teaches us how to be responsible in our daily life. (改为被动语态)

We _________ _________ how to be responsible in our daily life by keeping pet dogs.

【答案】are taught

【解析】

句意:养宠物狗教会我们如何在日常生活中负责任。

本句时态是一般现在时,改为被动语态时,时态不变,变化的是语态,即此句是一般现在时的被动语态。主动语态改为被动语态时,主动语态的宾语(动作的受动着)改为主谓,谓语动词改为“am/is/are+过去分词”,再加“其他成分”,最后加“by+主动语态的主语”。本句主语We,可知使用areteach的过去分词是taught。故答案为(1). are (2). taught

【题目】 People use their mouths for many things. They eat, talk, shout and sing. They smile and they kiss. In the English language, there are many expressions about the word “mouth”. But some of them are not so nice.

For example, if you say bad things about a person, the person might protest and say “Do not bad mouth me.”

Sometimes, people say something to a friend or family member that they later regret because it hurts that people’s feelings. Or they tell the person something they were not supposed to. The speaker might say: “I really put my foot in my mouth this time”. If this should happen, the speaker might feel down in the mouth, In other words, he might feel afraid for saying the wrong thing.

Sometimes when one person is speaking, he says the same thing that his friend was going to say. When this happens, the friend might say: “You took the words right out of my mouth!” Sometimes a person has a bad or unpleasant experience with another person. He might say that experience “left a bad taste in my mouth”. Or the person has possibly had a very scary experience, like being chased by an angry dog. He might say, “ I had my heart in my mouth.”

Some people have lots of money because they were born into a very rich family. There is an expression for this, too. You might say such a person “was born with a silver spoon in his mouth”. This rich person is the opposite of a person who lives from “hand to mouth”. This person is very poor and only has enough money for the most important things in life, like food.
