Объяснение
Step 1: the blank follows the adverb “很”, so we need an adjective. Step 2: the adjective that fits is “顺利” (smooth, successful); “及时” is also an adjective but means “in time” and is not used to judge a whole business trip. Step 3: the second clause “客人第二天就同意了我们的价格” (the client accepted our price the very next day) shows the trip went well, so “出差很顺利”. “表扬” (to praise) is a verb and cannot stand after “很” on its own.
Объяснение
Step 1: the blank comes after “准备很多” (prepare a lot of…), so it needs a noun object. Step 2: the noun in the bank is “材料” (documents, materials). Step 3: “例如成绩单、护照的复印件” (e.g. a transcript, a copy of the passport) lists exactly such papers. Note that “材料” often means “application documents”, not only “raw materials” as Vietnamese “vật liệu” suggests. “尊重” and “表扬” are verbs and cannot be the object of “准备”.
Объяснение
Step 1: the blank sits between the subject “技术部的同事” and the verb “赶到” (to rush over), so it must modify the verb. Step 2: “及时” (in time) is used right before a verb: “及时赶到” (arrived just in time). Step 3: the result “电脑里的东西一点儿也没丢” (nothing on the computer was lost) and “还好” (luckily) confirm that timing is the point. “顺利赶到” is grammatical but does not explain why nothing was lost, and “顺利” is already the key of item 1.
Объяснение
Step 1: after the modal “应该” we need a verb that takes the object “当地人的习惯” (the local people's customs). Step 2: the verbs in the bank are “尊重” (to respect) and “表扬” (to praise). Step 3: the first clause “每个国家都有自己的文化” (every country has its own culture) points to respecting local customs: “尊重当地人的习惯”. “表扬” praises a person for something good they did and does not go with “习惯” here.
Объяснение
Step 1: the sentence has the frame “不但……，（ ）……也……”, so the second clause must go further than the first. Step 2: “甚至” (even) introduces the more surprising case: not only foreign students but even some Chinese people can't explain it. Step 3: “甚至” is typically followed by “也 / 都”, as in “甚至有些中国人也说不清楚”. Words like “材料” or “及时” cannot open a clause and link it to the first one.
