【題目】 Researchers have discovered the first Earthsized planet. It was first marked by 【1】(science) using NASA’s Kepler telescope (望遠(yuǎn)鏡) ,so it’s called Kepler-186f. It lies about 500 light years from the Earth and goes【2】 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 of【9】 [‘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.
【答案】
【1】scientist
【2】around
【3】important
【4】planet
【5】exciting
【6】change
【7】life
【8】universe
【9】progress
【10】same
【解析】
這是一篇科普知識類閱讀,短文主要介紹美國宇航局利用開普勒望遠(yuǎn)鏡發(fā)現(xiàn)第一個地球大小的行星,所以被命名為Kepler-186f。這顆行星離它所環(huán)繞的恒星正處于合適的距離范圍內(nèi),以至于行星表面有液態(tài)水存在。Kepler-186f的發(fā)現(xiàn)是非常重要的,因為它是第一個與地球有相同的溫度和相同大小的行星。
【1】句意:科學(xué)家首先用美國國家航空航天局的開普勒望遠(yuǎn)鏡(Kepler Telescope)對它進(jìn)行了標(biāo)記,所以它被稱為開普勒186F。由using NASA’s Kepler telescope (望遠(yuǎn)鏡) 用美國國家航空航天局的開普勒望遠(yuǎn)鏡,可知,應(yīng)該是由科學(xué)家使用的。因此填:scientist。
【2】句意:它距地球500光年,繞著它的恒星運行。分析句子結(jié)構(gòu)可知,在動詞和名詞之間應(yīng)該填一個介詞,由語境可知,填:around,go around“繞著……轉(zhuǎn)”的意思。故答案為:around。
【3】句意:水是一個重要的條件,科學(xué)家認(rèn)為對于生命來說水是必要的。condition是名詞,前面應(yīng)該用形容詞來修飾,importance的形容詞為important。所以答案為:important。
【4】句意:這顆行星是地球表親,不是地球雙胞胎。根據(jù)音標(biāo)[‘plnt]提示可知,填單詞planet;再由謂語is可知,主語是單數(shù)。故答案為:planet。
【5】句意:找到一顆與地球相似的行星是非常令人興奮的。這句話的主語是find a planet similar to the Earth表示“物”,指的是“找到一顆與地球相似的行星”這件事,是令人興奮的。因此用形容詞interesting。故答案為:interesting。
【6】句意:這不是一件容易的工作,因為隨著我們得到更多的測量數(shù)據(jù),情況會發(fā)生變化。根據(jù)音標(biāo)[tend]提示可知,填單詞change;本題的時態(tài)為一般現(xiàn)在時,主語是things,為復(fù)數(shù),所以謂語用動詞原形。故答案為:change。
【7】句意:生活在這個星球上是可能的,但這并不意味著它有生命。根據(jù)The planet is the right distance from its star for water:not too close and not too far. 這顆行星與它的恒星距離正好,距離水不算太近,也不算太遠(yuǎn)。以及句子but that doesn’t mean there is life on it但這并不意味著它有生命。這句話是表示轉(zhuǎn)折,因此,前面說生活在這個星球上是可能的。故答案為:life。
【8】句意:到目前為止,科學(xué)家已經(jīng)在宇宙中發(fā)現(xiàn)了近1800顆行星。根據(jù)scientists have found nearly 1 ,800 planets科學(xué)家已經(jīng)發(fā)現(xiàn)了近1800顆行星?芍@些行星應(yīng)該是在宇宙中的。因此填universe,in the universe“在宇宙中”。所以答案為:universe。
【9】句意:在過去的一年里,在尋找類地行星方面取得了許多進(jìn)展。根據(jù)音標(biāo)[‘prgres ]提示可知,填單詞progress;progress“進(jìn)步”, 是不可數(shù)名詞。所以答案為:progress。
【10】句意:開普勒186F是非常重要的,因為它是第一顆幾乎與地球的溫度和大小相同的行星。根據(jù)the same size as the Earth和地球一樣大,可知,前面應(yīng)該是與地球有相同的溫度。因此填same。the same temperature相同的溫度。所以答案為:same。
