探究一
1. I’d like to help homeless people.
homeless意为“无家的，无家可归的”，它是home加否定后缀-less构成的，-less常用来构成形容词，意思是“无……的, 不能……的”。
类似的词：use + less → useless(无用的)
hope + less → hopeless(无望的)
care + less → careless(粗心的)
help + less → helpless(无助的)
end + less → endless(没完没了的)
The homeless people are pathetic.
这些无家可归的人是悲惨的。
This is a useless knife. The handle has broken.
这是把没用的小刀。刀把坏了。
