Are you stressed out, scared or worried all the time? Do you avoid going to certain places, seeing friends or doing certain things because of your worries? Do your worries keep you awake at night? If you’ve answered yes, you may be suffering from anxiety.

Anxiety is a normal and necessary part of life. Anxiety is your brain’s way of telling you about danger. It is anxiety which helps you jump out of the way if a car is speeding towards you. But if it gets out of hand, anxiety can get in the way of your getting on with life and can become a real problem. If this is the case for you, treatment may be a helpful way for you to get your anxiety under control.

Anxiety is a normal part of life. Some people may feel uneasy if moving to a new place and some may get overly anxious in certain situations. There are lots of reasons for this. One main reason is after a stressful thing which has happened in your life. So, if you are involved in a car crash, it’s quite likely that you will be more worried than other people around cars and driving.

Being anxious also probably runs in families. If your parents suffer from anxiety then you are more likely to be anxious too. This is probably partly due to genetics, and partly because of how things are when you’re growing up.

Even though people don’t talk about it much, anxiety is one of the most common mental health problems. About 1 in 4 people will have an anxiety problem at some time in their life.

If you have an anxiety problem it’s hard for other people to understand why something that doesn’t worry them, like being in a crowd of people, can be so scary for you. This can make you feel separated and lonely, as may become worse and worse.

The good news is there are lots of excellent treatments available for anxiety. These include taking therapies (疗法) and drugs.

阅读下文，完成以下问题。

纽约所罗门兄弟公司的电信分析师葛鲁曼说：“我们正从一个四周有护城河阻挡外敌的行业，转变成一个真正没有疆界的行为。”他说：未来的发展将使美国电话电报公司能在德国提供电话服务，就像宝马公司在美国卖汽车一样容易。”分析师同时还指出，许多冗员充斥或资金不足的电信公司将无法在新环境中生存。

虽然全球化对消费者是大好消息，但这个受新科技和跨国电话业务需求所推动的趋势，却已经带来电信业的大变革。全球最大的两家电信业者日本电信电话公司和美国电话电报公司宣布重大改革： 日本电信电话公司将对国内外的竞争者进一步开放市场，美国电话电报公司则分解成三个独立的全球性公司。全球最大的电信设备制造商之一法国阿尔卡泰尔—阿尔斯通公司，因激烈的国际竞争而严重亏损并且宣布大幅裁员。荷兰和西班牙的电话公司在全球发行几亿美元的新股票，以筹募资金。德国和法国电话公司在华盛顿和布鲁塞尔积极游说，要求政府允许购买美国斯普林特公司20%股权。

据所罗门兄弟公司的资料，为了应付全球电信市场大战，未来12个月在市场上推出的电信业股票总值将达368.5亿美元。手笔最大的德国电信公司，明年春季或夏季将抛出约15%的股票，总值100亿美元。

分析师关于“护城河”和“疆界”的比喻，强调的意思是（）。

A．该公司的利益将不再能受到有效的保护。

B．信市场正面临国际化潮流的强烈冲击。

C．各国电信业将不再是受各国政府保护的行业。

D．国际电信市场将出现外人难以想象的激烈竞争。
