【题目】 Researchers have discovered the first Earthsized planet. It was first marked by 1(science) using NASA’s Kepler telescope (望远镜) so it’s called Kepler-186f. It lies about 500 light years from the Earth and goes2 its star. The planet is the right distance from its star for water not too close and not too far. Water is one 3(importance) condition that scientists guess is necessary for life. So it could have water and possible life. It’s called a true Earth cousin.

“This 4 [‘plnt] is an Earth cousin,not an Earth twin ,” said Barclay,who is among a team of scientists reporting on the discovery in the magazine Science this week.

“It’s very 5(excited) to find a planet similar to the Earth”’ Barclay said. “It’s not easy work because things 6 [tend] as we get more measurements. ”

Scientists don't know anything about the air of Kepler-186f,but it will be a task for future telescopes that can study for chemicals that have something to do with life.

“It’s possible for 7 to live on this planet,but that doesn’t mean there is life on it ,” Barclay said.

So far,scientists have found nearly 1 ,800 planets in the 8

“The past year has seen a lot of9 [‘prgres ] in the search for Earthlike planets. Kepler-186f is very important because it is the first planet that is the 10 temperature and is almost the same size as the Earth ,” scientist David Charbonneau wrote in an email.

【解析】

这是一篇科普知识类阅读,短文主要介绍美国宇航局利用开普勒望远镜发现第一个地球大小的行星,所以被命名为Kepler-186f。这颗行星离它所环绕的恒星正处于合适的距离范围内,以至于行星表面有液态水存在。Kepler-186f的发现是非常重要的,因为它是第一个与地球有相同的温度和相同大小的行星。

1句意:科学家首先用美国国家航空航天局的开普勒望远镜(Kepler Telescope)对它进行了标记,所以它被称为开普勒186F。由using NASA’s Kepler telescope (望远镜) 用美国国家航空航天局的开普勒望远镜,可知,应该是由科学家使用的。因此填:scientist

2句意:它距地球500光年,绕着它的恒星运行。分析句子结构可知,在动词和名词之间应该填一个介词,由语境可知,填:aroundgo around“绕着……的意思。故答案为:around

3句意:水是一个重要的条件,科学家认为对于生命来说水是必要的。condition是名词,前面应该用形容词来修饰,importance的形容词为important。所以答案为:important

4句意:这颗行星是地球表亲,不是地球双胞胎。根据音标[‘plnt]提示可知,填单词planet;再由谓语is可知,主语是单数。故答案为:planet

5句意:找到一颗与地球相似的行星是非常令人兴奋的。这句话的主语是find a planet similar to the Earth表示,指的是找到一颗与地球相似的行星这件事,是令人兴奋的。因此用形容词interesting。故答案为:interesting

6句意:这不是一件容易的工作,因为随着我们得到更多的测量数据,情况会发生变化。根据音标[tend]提示可知,填单词change;本题的时态为一般现在时,主语是things,为复数,所以谓语用动词原形。故答案为:change

7句意:生活在这个星球上是可能的,但这并不意味着它有生命。根据The planet is the right distance from its star for waternot too close and not too far. 这颗行星与它的恒星距离正好,距离水不算太近,也不算太远。以及句子but that doesn’t mean there is life on it但这并不意味着它有生命。这句话是表示转折,因此,前面说生活在这个星球上是可能的。故答案为:life

8句意:到目前为止,科学家已经在宇宙中发现了近1800颗行星。根据scientists have found nearly 1 ,800 planets科学家已经发现了近1800颗行星。可知,这些行星应该是在宇宙中的。因此填universein the universe“在宇宙中。所以答案为:universe

9句意:在过去的一年里,在寻找类地行星方面取得了许多进展。根据音标[‘prgres ]提示可知,填单词progressprogress“进步 是不可数名词。所以答案为:progress

10句意:开普勒186F是非常重要的,因为它是第一颗几乎与地球的温度和大小相同的行星。根据the same size as the Earth和地球一样大,可知,前面应该是与地球有相同的温度。因此填samethe same temperature相同的温度。所以答案为:same

【题目】 Have you ever been cycling(骑自行车运动)? This spring my elder brother and I 1 (spend) a long weekend cycling in the countryside.
