2018考研英语复习正在进行中，何凯文老师的每日一句每年都很受关注，在长难句解析拆分句子的方法也讲解得十分到位，文都考研官网汇总了何凯文2018考研英语每日一句，下面是何凯文每日一句第228句。

一颗离地球18光年的白矮星(white dwarf)Stein 2051 B的质量在长达一个世纪以来一直是争议的对象。现在一个天文家团队利用爱因斯坦首次预测的天体现象——引力透镜(gravitational lensing)衡量出了它的准确质量，结束了一桩百年公案(settled a 100-year-old debate)。研究者使用哈勃望远镜(Hubble Space Telescope)观测白矮星蚀掉(eclipse)另一个距离更远的恒星(more distant star)，通过当时距离的变化数据算出了精确的结果。这也是爱因斯坦的相对论第一次运用在天体的质量测算(measure the mass)上。

今天的句子：

A ray of light normally travels in a straight line through empty space, but if the ray passes close by a massive object, the curve in space created by the star acts like a bend in the road, causing the light ray to veer away from its formerly straight path.

词汇突破：

1.Ray 光线

2.Massive 巨大的

3.Curve 曲线，曲面

4.Bend 弯曲

5.Veer away偏离

6.Path路径

确定主干：

并列一：A ray of light normally travels in a straight line through empty space.

并列二：but if…the curve in space acts like a bend in the road

切分成分：

1.if the ray passes close by a massive object条件状语从句

2.created by the star后置定语，修饰curve

4.causing the light ray to veer away from its formerly straight path 状语;

=the curve in space cause...

参考译文：光通常在真空中直线传播，但如果近距离经过一个质量极大的物体，恒星造成的空间曲面会像路中出现的弯道一样，让光偏离原来的直线路径。

明天的题目：

There are some od arguments for a technical education given the right kind of student. Many European schools introduce the concept of professional training early on in order to make sure children are properly equipped for the professions they want to join. It is, however, presumptuous to insist that there will only be so many jobs for so many scientists, so many businessmen, so many accountants. Besides, this is unlikely to produce the needed number of every kind of professional in a country as large as ours and where the economy is spread over so many states and involves so many international corporations.

61. It could be inferred from the passage that in the author's country the European model of professional training is ________.

[A] dependent upon the starting age of candidates

[B] worth trying in various social sections

[C] of little practical value

[D] attractive to every kind of professional
