When millions of people around the world were shocked by the pictures of drowned three-year-old Syrian boy Aylan Kurdi lying washed up on a Turkish beach and the massive refugee crisis engulfing Europe, they should see through the fact that the United States is mainly responsible for all the mess.

The main sources of today's refugees -- Syria, Libya, Iraq and Afghanistan -- are targets of U.S. intervention, which led to devastation, disorder and deteriorating domestic security. People in those countries could no longer enjoy even basic human rights. Many of them had no choice but to flee for life, not only to neighboring countries, but to Europe. Thousands of people didn't survive the dangerous journey as they ventured to cross the Mediterranean into Europe.

While the European countries are accused of indifference and incapabilities to cope with the refugee crisis, the Unites States, their closest ally and the major cause of the crisis, seems not to have realized its moral obligation to help clean up the mess.

Syria is the latest country following Iraq and Libya to become the victim of U.S. intervention in the Middle East. Having been mired in a full-blown civil war for four years due to persistent U.S.-led Western intervention, the country was the largest source of refugees bound for Europe in 2013, 2014 and the first half of this year.

    The militants of the so-called Islamic State (IS), emerging from the Syrian oppositions which were supported by the U.S. to topple the Syrian government, have launched numerous attacks against Syrian civilians, whose lives are at peril if they hang on in their own country.

    As the leader of the world, it is a shame for the United States to stir up disorder, anarchism (无政府主义) and the emergence of extremist and terrorist groups in those countries by its selfish foreign policies.

Now as Europe struggles to cope with a daily influx of thousands of refugees, the U.S. should act immediately and do more to help solve the refugee crisis and work out long-term measures to help troubled countries and regions restore calm, stability and normal life as soon as possible.

1. Why should U.S. bear blame for European refugee, humanitarian crisis?

B Because U.S. supported the militants of the so-called Islamic State (IS)

C Because U.S. interfered wilfully in the nationality affairs in other countries.

解析：选C。推理判断题。根据文章第一段... the United States is mainly responsible for all the mess. 和第二段...are targets of U.S. intervention, which led to devastation, chaos...以及第四段to become the victim of U.S. intervention in the Middle East.可知，美国的肆意干涉最终导致了难民潮和人道危机，因此应该为此负责。

2.What does the word“influx”mean in the last paragraph?

A influence

D inflow

解析：选D。词义猜测题。根据单词构造 influx=in进入+flux流量 以及文章最后一段Now as Europe struggles to cope with a daily influx of thousands of refugees...可知，目前当欧洲致力于应对每天流入的成千上万难民时，美国也不应该袖手旁观，因此D符合上下文。

3.Why did the refugees venture to cross the Mediterranean?
