All these sentences are missing
particles. I can't explain it too well, I always failed English. I was more into science and math ;) Here is a website with some examples and a self test section that I think you would find helpful.
Prepositional and adverbial particles in English grammar practice
Also...not all your sentences appear to be in order. I'm going to take a crack at laying the sentences out for you ,and you try to put in the correct particle.
1. What kind __ holiday ___ you interested __?
2. He __ _ man that likes people __ first sight.
3. Many people out __ work become depressed.
4. Children should __ warned __ not speak __ strangers.
5. ___ desert receives twenty-five centimeters less rainfall every year.
That's more than enough to get you in the right direction. To do anymore would not be helping you at all. Give it your best and don't be afraid to make a mistake. We're your testing ground
