without doubt 与with no doubt相同吗

Kids who receive special education are, without doubt, the hardest working children in any school. When they are having difficulty learning basic literacy and number concepts, when they break rules, when they need more services, support and adult attention than their peers, then they are struggling the hardest. In psychology, we are trained to think that if we are feeling angry or confused when sitting with a patient, then we are probably feeling just what our patient is feeling. The same is true for students with disabilities. Whatever we feel when we work with them, they are probably feeling as they work with us.
If you have a disability that affects your education, then you have a brain disorder. Because education, even in mathematics, is largely verbal（用言辞）, most brain disorders responsible for educational disabilities affect language, and how you process words and ideas in written and oral form. To i magine how much effort a child with a language disability spends each school day, imagine yourself attending a school today taught in a language you had a basic understanding of. Imagine though, that while you seem fluent to others, you have trouble when people talk too fast, use idioms or expressions.
When adults and classmates blame, or criticize kids who receive special education, they are struggling with their own confusion. It is difficult to imagine the world as it is lived by someone with an educational disability. It is difficult to understand how someone who can be so "normal" can have so many problems. It is so easy to imagine that if they just tried harder... without understanding that just to do the ordinary, kids with disabilities are making an extraordinary effort.
