二、用方框中所给词语的适当形式填空,每词仅用一次

2. She has two on the website—one for study and one for games.
3. It's important to tell the , even if it's hard.
4. We need to with our classmates to finish the group work.
5. you finish your homework, you can play outside.

1. Avoid
2. accounts
3. truth
4. connect
5. Once

1.根据“...using easy-to-guess information”可知此处要用避免做某事的句型，avoid doing sth避免做某事，这里是祈使句，用动词原形avoid，且在句首，首字母大写。
2.根据“two...”可知此处要填一个名词的复数形式，two accounts两个账户，符合语境。
3.根据“tell the...”可知此处要填一个名词，tell the truth说实话，符合语境。
4.根据“need to...with”可知此处要填一个动词，connect with和……联系，符合语境，need to do sth需要做某事，所以此处用动词原形。
5.根据“...you finish...you can...”可知此处要填一个连词，once一旦，引导条件状语从句，符合语境，且在句首，首字母大写。

三、根据句意写单词,每空一词
1. No matter whether you like it not, social media is becoming popular.
2. Social media allows people to connect friends.
3. you have accounts different apps, make sure you use strong passwords.
4. Not every person online is friendly or telling the truth themselves.
5. Your parents and teachers want the best you.

1. or
2. with
3. If; on
4. about
5. for

1. “No matter whether you like it or not”是固定搭配，表示“无论你喜欢与否”，所以填“or”。
2. “connect with sb.”是固定短语，意为“和某人联系”，这里说社交媒体使人们能和朋友联系，填“with”。
3. 第一空，根据语境“如果你有不同应用程序的账户”，表示假设用“If”；第二空“在不同应用程序上的账户”，用“on”表示“在……方面；关于”。
4. “tell the truth about...”表示“说出关于……的真相”，这里说不是每个在网上的人都是友好的或说出关于他们自己的真相，填“about”。
5. “want the best for sb.”是固定短语，意为“为某人着想；为某人提供最好的”，填“for”。
