三、阅读理解

It is 40 meters long and 6 meters wide. This must be the biggest bus you have ever seen. It can carry 1,200 to 1,400 people.

It is China’s new Super Bus. It is going for a test run in Beijing at the end of this year. Some other cities are also interested in running the Super Bus. They hope the traffic problems will be solved.

The Super Bus runs along fixed tracks . The bus sits on top of two 2.2-meter-tall legs. The legs have wheels at one end. Small cars can drive under the bus, so the Super Bus does not take up road space. The bus runs on electricity and solar power. It can travel up to 60 km every hour. Its creator, Song Youzhou, says a lot of traffic jams (堵塞) will be reduced…

The Super Bus can do the work of 40 buses. In that way, it can save 860 tons of fuel (燃料) every year, according to Song.

“To build a Super Bus and its track costs less than building subways. Subways are nearly ten times more expensive to build.” Song said.

Some people worry that the Super Bus may not be safe. However, Song says there’s no need for concern. The Super Bus has laser scanners (激光扫描仪) between its legs. The scanners make sure the cars keep a safe distance.

Mission to Mars

On July 4, 1997, space exploration took a huge step. On that day, a spacecraft called Pathfinder landed on Mars. The National Aeronautics and Space Administration (NASA) sent Pathfinder to discover new information about the Red Planet.

The mission was a complete success. After landing, Pathfinder sent a small rover (漫游机器人), Sojourner, onto the planet's surface. Sojourner explored more than 250 square meters of Mars. Together, designed Sojourner to last for only seven days, but little vehicle ran twelve times longer! Pathfinder surprised scientists, too. It sent back information for almost three months. That was three times longer than it was built to last.

Because Pathfinder and Sojourner ran for so long, scientists got more information than they ever dreamed of getting. For one thing, they discovered that Mars is very sandy. Pictures of sand dunes around the land site hint that Mars once had water. Scientists know that water means life. Was there ever life on Mars? We don't know yet. In addition, the Pathfinder mission told scientists that Mars is dusty. Huge "dust devils" on Mars spit enormous amounts of dust into the Martian air. Pathfinder also discovered frosty Martian temperatures at 200 degrees below zero Fahrenheit. At that temperature, a glass of water would freeze solid in just a few seconds.

In October, scientists lost Pathfinder's signal because the spacecraft's battery had run down. They tried to revive the signal but had no luck. The mission officially ended on November 4.

Scientists hope to use the knowledge from these missions to better understand how life on earth began. They will also use it to plan future Mars missions.

1．What did NASA do to get information about Mars?

A．NASA sent the spacecraft Sojourner to Mars.

B．NASA sent engineers on a three-month space mission.

C．NASA sent the spacecraft Pathfinder to Mars.

D．NASA sent astronauts to run tests for seven days.

2．What was the main reason NASA considered the Pathfinder mission a success?

A．Scientists found out that Mars is very cold and dusty.

B．Scientists got more information than they ever dreamed of getting.

C．Scientists learned that Mars definitely had water at one time.

D．Scientists found out that there was once life on Mars.

3．You can learn from this passage that ________

A．dust devils on Mars made the photographs hard to see.

B．Martian temperatures caused Pathfinder's battery to fail.

C．scientists suspect that life on Earth began on Mars.

D．scientists will look for signs that life existed on Mars.

参考答案

一、1．D【解析】句意：如果你继续努力，总有一天你会成功的。A. some days一些天；B. a day一天；C. the day特指的一天；D. one day指将来的某一天。结合语境可知，成功的那一天是不确定的，因此排除C；而且成功了就是一天之际，因此也不用复数。排除A；由will可知，本题是一般将来时，因此选择one day指将来的某一天。故选D。

2．B【解析】句意：我希望乘宇宙飞船去参观其他行星，比如火星。spaceship“宇宙飞船”，是一种交通工具，因此：乘宇宙飞船，用介词by。排除C/D；on在……上；like作介词，意为“比如……”用来表示举例。语境是：我希望乘宇宙飞船去参观其他行星，比如火星。故选B。

3．B【解析】句意：我妹妹几乎从不吃垃圾食品以便保持健康。A. so that以便，其后跟句子；B. in order to为了，跟动词原形；C. for为了；D. in order that为了（后面跟句子）。根据keep healthy可知，keep是动词原形，因此排除A/D；for是介词后跟动名词，所以选项C不对。故选B。

4．D【解析】句意：自从中国发射“嫦娥一号”以来，已经有3年了。本题考查句型：It is（has been）+时间+since+持续性动词的过去时”，表示“自从……以来到现在已有多久。”本题中的选项A/B的第二个空应该用since，而不用for或with，因此排除；选项C的第一个空用was，那么在since引导的从句中，应该用过去完成时。所以C不对。故选D。

5．C【解析】句意：——你借了几本书？——四本。我昨天借了一本，今天早上又借了三本。A. other指另外的人或物；B. the other表示“两个数量中的另一个”，表示特指，总数为俩；C. another只能用于三个或更多的人或物，泛指同类事物中的三者或三者以上的“另一个”，表示泛指。D. others只能作代词，意思是“其它的人、物、事等”，常用来泛指。本文的语境是：我昨天借了一本，今天早上又借了三本。因此选择another“又，再”。故选C。

二、1. is life on Mars

三、文章讲述的是中国最大的运载火箭长征五号第三枚火箭于2019年12月27日从海南文昌航天发射中心成功发射升空。以及中国在此方面近几年来取得的成就。

1．was named【解析】句意：这枚火箭被命名为长征五号Y3。句子主语rocket是单数名词，与动词name之间是被动关系，且讲述的是过去的事情，所以应该用一般过去时的被动结构，故填was named。

2．heaviest【解析】句意：它于晚上8点45分从发射中心离开地面，搭载着中国最重、最现代化的通信卫星“时建20号”。and并列两部分后面是最高级形式，则前面也用最高级，且空格前有the，这里表达的是“最重的”，故填heaviest。

3．its【解析】句意：大约2220秒后，卫星被送入预定轨道。由句意理解可知，这里指的是“它的预定轨道”，指代“某人的”要用物主代词，且空格后有名词，所以要用形容词性物主代词，故填its。

4．made【解析】句意：长征五号火箭于2016年11月3日从文昌首次飞行。句中的时间是on Nov. 3, 2016，表示过去，所以动词要用过去式，故填made。

5．second【解析】句意：然而，第二大火箭长征五号Y2于2017年7月2日发生故障。根据前文“The third long March-5 rocket, China's largest carrier rocket was _____ (success) launched(发射)…The rocket _____ (name) Long March-5 Y3.”可知，这里的Y2是第二大的火箭，英语中表达“第几”要用序数词，故填second。

6．Compared【解析】句意：与长征五号Y2相比，新型火箭长征五号Y3显示了200多项技术改进。空格与句子主语“the new rocket Long March-5 Y3”之间是“被比较”的关系，所以这里应该用过去分词，故填Compared。

7．proud【解析】句意：我们很自豪能够参与到展示中国火箭技术最高水平的长征五号火箭研制中。空格在句中是作表语，是放在be动词之后，应该用形容词表达，故填proud。

8．silence【解析】句意：在文昌沉寂了两年多之后，中国人兴奋地欢迎‘王’的回归。由句意可知，这里表达的是“两年的沉寂”，这里是of所有格形式，所以应该用名词形式，故填silence。

9．have completed【解析】句意：长征系列火箭已完成323次飞行。句中有“Since+时间段+ago”，是现在完成时的标志词，而句子主语是复数名词rockets，所以这里应该用have，故填have completed。

10．will see【解析】句意：随着长征五号Y3火箭的成功发射，中国明年将迎来太空活动繁忙的一年。句中的时间next year可知，这里应该用一般将来时，结构是“will+动词原形”，故填will see。
