Would you like to get in touch with your friends? Do you send a text or make a phone call? A new study in a journal suggests that you should call instead of 【小题1】(send) a text. Calling makes you feel more connected with your friends.

Scientists asked 200 people 【小题2】(contact) an old friend by email or by phone. Many people 【小题3】(think) that a phone call would be more awkward. But 【小题4】(actual), hearing someone’s voice made the experience 【小题5】(good).

According to 【小题6】study, people like to text because they can have more control. They can think about their message before they send it, and they won’t be cut off while messaging. But 【小题7】the other hand, texting can make 【小题8】 hard to understand the true meaning of a conversation. Making phone calls 【小题9】(be) more natural.

This is called “community group-buy”, also 【小题7】 (know) as “interactive commerce”.

The second is the way PDD has broken the myth that the giants of online shopping are 【小题8】 (absolute) unbeatable. Until a few years ago, China's e-commerce market seemed a two-way contest between Alibaba and JD. COM, 【小题9】 it is not the case now. Experts expect PDD's share of online sales in China 【小题10】 (be) larger than that of JD in 2021 and the number of users to surpass Alibaba.
