How to look up a word in a dictionary?

1. When you look up a word in the

dictionary, you must pay attention to

the first letter of the word.

2. When two words begin with the same

letter, you have to look at the second

letter to find the word.

3. If both the first and the second letter

are the same, look at the third one and

so on.

tical order. order 在此句中是“顺序”的意思。 in…order 意为“以…的顺序”

3. look up “ 在（书或资料）等中查找，it/ them 作宾语应放在中间，另外还有“向上看”的意思。pay attention to 注意， to 是介词，后跟动词变为动名词。4. begin with … 或 start with… 意为“以…开始” The concert began with a piano solo.
