答案：
解析：
1.祈使句的否定形式在动词前加don’t即可，故本题应该写成Don’t climb the tree.
2.将复数改为单数，应该将所有的单词都改，可数名词应在前加冠词，故本题应该写成Is this an orange orange？
3.对职业提问可用疑问词what，后跟一般疑问句，故本题应该写成What is the girl？
4.对时间长度提问的用how long，后跟一般疑问句，故本题应该写成How long do you read English everyday？
5.对动词短语表示做某事提问用what，动词部分应该补上do的相应形式，故本题应写成What does his mother want to do？
