1. I have to finish my story about animals.
have to 不得不，后面跟动词原形，表示客观要求某人需要做某事，有人称和数及时态的变化，例如：
She isn’t very well these days and has to stay at home.
We have to go and help him.
You don’t have to tell me this.
Do you have to do everything.
She doesn’t have to come this afternoon. 注意：
have to 在口语中也可用have got to 代替，意思与have to 一样，也表示客观需要或义务。辨析：have to 与must
两者都有“必须”的意思，它们的基本区别是：
have to 表示客观的需要，而must则表示主观的需要，例如：
We have to clean our classroom every day.
We must clean our classroom every day.
must 也表示“义务”，这种义务来自讲话人，表示讲话人的要求，当我们表示这种要求不是来自讲话者，而是来自别人或其他外界因素。（如各种规章制度）时，常常用have to。 例如：
You have to do your exercises in class.
I really must stop smoking. 2. raise v. 举起 例如：
If you have any questions, you can raise your hands first.
Please raise your voice, I can’t hear you.
同义词lift
辨析：raise，rise 和lift
raise 是及物动词，后面可接宾语，多指将物体垂直向高处或将其从较低的平面移至较高的平面。
rise 是不及物动词，不可以加宾语，主语一般是日、月、云、雾、烟、温度、河水、物价等。
lift 表示“从平面上提示，使直立”等，可以和raise替换，而lift 强调举起某些沉重物体需要费一些力气。3. In a little while you’ll be nothing but a stick.
①nothing but 仅仅，只，例如：
There is nothing but a story book in his bag.
The child dreams of nothing but going to the zoo.
He did nothing but grumble.
The baby can do nothing but crying.
My brother ate nothing but a bowl of porridge.
②in a little while 过一会儿，通常用于将来时
You’ll be warmer in a little while. 4. You may come to an end soon.

come to a stop 停下来
come to an understanding 商定、约定、谅解
come to hand 到手
come to life 苏醒，活过来 come to light 真相大白
come to little 无甚结果
come to nothing 成为泡影

come to the same thing 结果相同，都一样5. “No”, replied the rose tree.
