B.主要生长在肌肉之间

D.手术前可通过血管造影确定手术范围

E.可以通过局部注射硬化剂来治疗

答案

参考答案:B

解析:肿瘤由扩大的血管腔和衬有内皮细胞的血窦组成。血窦大小不一,有如海绵状结构,窦腔内充满静脉血,彼此交通。表现为无自觉症状、生长缓慢的柔软肿块。头低位时,肿瘤因充血而扩大,恢复正常体位后,肿块即恢复原状。表浅的肿瘤,表面皮肤或黏膜呈青紫色。深部者,皮色正常。触诊时肿块柔软,边界不清,无压痛。挤压时肿块缩小,压力解除后则恢复原来大小。

     Who's building the new China? It's not the factory owners or the business men and women of China.

It's someone else. We see them every day, They work day and night in the terrible working conditions and

weather. They build the roads, the theaters, the cinemas and the supermarkets. They even clean up our

rubbish. They are China's migrant workers (民工).

     More than 140 million workers have left their homes in the countryside to look for jobs in big cities all

over China. They hope to be rich, but they realize they have many difficulties in making enough money. And

one of the difficulties that these workers have is the pride and discrimination (歧视) from the people in cities.

When night falls, everywhere I look I see the sad faces of the migrant workers. Many are living far away

from those whom they love. Yes, they dress differently, they speak differently, and they have different habits,

but they work hard.The people in cities regard them as outsiders, and most governments refuse to give them

medical care and public schooling for their children. If China hopes to move into the future, many things need

to change. The first is discrimination! We need to stop our discrimination against the migrant workers of

China! They may not make as much money as some people in cities, but they are good honest people just

trying to survive this game of life. These workers are very important and necessary to China's economic

(经济) development and have become an important force for the change of Chinese society. They are building

the new China, so we should help them.
