问题 单项选择题

单位重量小于()g/m2的纸质、布质壁纸,当直接粘贴在A级基材上时,可作为()级装修材料使用。

A.300、B1

B.300、B2

C.400、B1

D.400、B2

答案

参考答案:A

解析:A。本题考查的是壁纸的装修规定。常用壁纸有纸质壁纸、布质壁纸两种。所谓纸质壁纸是指以天然纤维作为纸基、纸面上印成各种图案的一种墙纸。这种墙纸强度和韧性差,不耐水。布质壁纸是指将纯棉、化纤布、麻等天然纤维材料经过处理、印花、涂层制成的墙纸。这两类材料分解产生的可燃气体、发烟量相对较少。尤其是被直接粘贴于A级基材上且单位质量小于30%/m2时,在试验过程中,几乎不会出现火焰蔓延的现象,为此可将这类直接粘贴在A级基材上的壁纸作为Bl级装修材料使用。故本题选项为A。

Daniel was always making excuses for forgetting to do things. His usual excuse was: “ I was too busy.” or “I didn’t have time.”

Daniel’s parents were worried about him. “ He shouldn’t go through life making excuses all the time.” his father said. “ No one will trust him to do anything. He won’t be able to keep a job. No sensible(明智的)girl will marry him.”

“I don’t know what we can do.” his mother said.

“I have an idea.” his father said. “If this doesn’t work, nothing will.”

The next day was Daniel’s birthday. He was really looking forward to getting exciting presents. He woke up, expecting his parents to wish him a happy birthday. But all day what they said was “Good morning, Daniel. Hurry, or you will be late for school.” There were no presents, not even a card. He was really disappointed.

“Never mind.” he thought. (3) “There’ll be a surprise for me after school.” But there wasn’t. Sadly he said to his parents at dinner, “Today’s my birthday.”

“Oh,” his father said. “So it is. I forgot.”

“So did I.” his mother said.

“How could you forget?” Daniel asked. “There must be a reason.”

“Well, yes.” his father said. “We have a really good excuse for forgetting your birthday, Daniel. We didn’t remember your birthday because we were too busy.”

Poor Daniel! He never had a silly excuse for not doing something again.
