In most restaurants in China, forks and knives are not provided on the dining tables. If you find difficulty to use chopsticks, you will have to ask waiters to bring you the knife and fork.

You can say 请给我刀叉 (qǐng gěi wǒ dāo chā ), meaning please give me knife and fork.
请给我 ((qǐng gěi wǒ) is a very useful phrase to ask for things, meaning please give me
Knife and fork is 刀叉 (dāo chā)
刀 (dāo) means knife or knives
叉 (chā) means or forks.
You can often find spoons on the table, and most time, its a China spoon rather than the stainless ones found in the Western restaurants. There are several ways to say spoon in Chinese. You can say 勺子 (sháo zǐ ) or 调羹 (diào gēng)
