The earth became so violent that it was not clear whether the shape would last or not.2.这个女孩懂三门外语，这使她更容易找到一份好工作The girl knows three foreign languages, which makes it easier for her to find a good job.3.生活就像一个故事，重要的不是它有多长，而是有多好 Life is like a tale. What matters is not how long it is, but how good it is.4．她告诉我，对于她来讲最重要的是她的家庭 What was most important to her, she told me, was her family. 5．常言道，“有志者事竟成”，我们的努力迟早会有所回报As a proverb saying goes, “where there is a will, there is a way”. Our efforts will pay off in time.6.据报道，最近发现了一颗行星，它几乎是地球的三倍大，人类有望能在上面生活。

三种倍数表达法)a. It is reported that a new planet has been discovered recently. It’s almost three times the size of Earth, and hopefully it can support human life.b. It is reported that a new planet has been discovered recently. It’s almost twice larger than Earth, and hopefully it can support human life.c. It is reported that a new planet has been discovered recently. It’s almost three times as large as Earth, and hopefully it can support human life.7.既然你已经长大，你不应该再依赖你的父母了Now that you have grown up, you should not rely on your parents.8.然而，一种普遍为人们所接受的理论是：宇宙起源于一次大爆炸，这次大爆炸将物质投射到四面八方。

However, according to a widely accepted theory, the universe began with a “Big Bang” that threw matter in all directions.9.水对于生命的发展会起关键作用，这一点在当时并不明显It was not immediately obvious that water was to be fundamental to the development of life.10.很多科学家相信，由于地球上长期有水存在，使地球得以把有害气体和酸性物质溶解在海洋里What many scientists believe is that the continued presence of water allowed the earth to dissolve harmful gases and acids into the oceans and seas. 11.他们把过多的二氧化碳释放到大气层中，这使得地球上的热不能释放到太空中去They are putting too much carbon dioxide into the atmosphere, which prevents heat from escaping from the earth into space.12.所以，在未来的数百万年中，生命能否在地球上延续取决于这个问题能否得到解决。

So whether life will continue on the earth for millions of years to come will depend on whether this problem can be solved.。
