Question 13 is based on the conversation you have just heard.

听力原文

M: I’m getting a bit hungry.

W: Yes, me too. I’m starving. Are you going to prepare a meal for us?

M: (12) [No, sorry, I’m actually pretty worn out.] Let’s just go out somewhere close to eat.

W: Well, I think we should stay in and save some cash. Can we get a meal delivered?

M: Yeah, great. (13) [I’ll use that food delivery app on my phone.] What do you want, fried chicken, hamburgers, or fish and chips?

W: Oh, can we stay away from the junk food? How about something healthy?

M: Okay, well, there’s a place that does salads.

W: Let me have a look at that. Yeah, that looks delicious, but to be honest, I’d prefer something hot, not cold.

M: How about Indian food?

W: (14) [That’s not the kind of hot I mean. I’m just not a fan of sauces that make me sweat and cry.] I need something mild.

M: Okay. So would you consider Mexican? Oh no, sorry, there’s also very hot pepper in that. Would you like some Italian food, perhaps? It’s a bit heavy, but it’s great food for a cold night like this.

W: Pizza? Spaghetti with creamy sauce? I know it’s really tasty and great comfort food, but it’s too fattening for me. I’m trying to keep a slim figure, you know.

M: (15) [Oh, you’re really difficult to please.] Well, there’s a nice Chinese restaurant that delivers.

W: Yes. I love Chinese food. Let me see. Oh it’s 50 kilometers away.

M: That’s a bit too far away. Do you feel like Vietnamese food then?

W: Yeah, awesome. It’s healthy, and we can afford it.

M: Great. Let’s order Vietnamese right away.

13. What does the man say he’ll do on his phone?

解析：B。录音中女士提议叫外卖，男士同意，说他要用手机上的外卖APP（food delivery app.），由此可知男士是要用手机点外卖，B项符合题意，故为正确答案。

错项排除：A项的Book a table在录音中无依据，故排除。录音中虽然提到各种菜式，包括印度菜、墨西哥菜、意大利菜等，但并没有说要下载菜单，故C项排除。D项利用录音中出现的restaurant进行干扰，但男士只是说有一家不错的中餐馆，并没有说要在手机上找一家餐馆，故D项排除。
