Bonjour, tu devrais soigner un peu ton orthographe :) !

What colors are your uniforms ?
Look at these stars ! Very bright (les adjectifs ne prennent pas la marque du pluriel).
These policemen (man devient men au pluriel comme woman devient women) are Scottish (je suppose qu'il manque "are' dans ta phrase). They like whisky/whiskies (je ne suis pas suûre pour le pluriel de whisky).
What are these horrible insects ? - These are spiders.
