The moon may shine white above us most nights of the year, but how much do we know about Earth’s neighbor and what lies beneath its surface? Scientists are aiming to find out.

On Jan 3, 2019, China’s Change 4 spacecraft landed on the far side of the moon a first for humanity. It released a small probe（探测器）,Yutu 2, or Jade Rabbit 2, which began to search beneath the moon’s surface using Lunar Penetrating Radar（探测雷达）. These radio signals can reach 40 meters underground, three times the depth of the Chang’e 3 lunar probe launched in 2013 for the near side of the moon, China Daily reported.

In a study published in the journal Science Advances, researchers found that the lunar soil’s top layer on the far side of the moon was much thicker than expected ﹣ about 40 meters. Other scientists only expected about 6 millimeters of soil based on NASA observations during the Apollo moon landings, according to The New York Times.

“It’s a fine, dusty, sandy environment, said one of the authors of the study, Elena Pettinelli, a physics and mathematics professor at Rome Tre University, Rome.

Yutu 2 is specifically exploring the Von Karman crater（大坑）,a large hole that’s 180kilometers wide and also the landing site of Chang’e 4. It’s part of an even larger, older crater spanning more than 1,770 kilometers.

“The subsurface at the Chang’e 4 landing site is very complex,” said Li Chunlai, a research professor and deputy director﹣general of National Astronomical Observatories of the Chinese Academy of Sciences. Observations suggest that the subsurface material is totally different than the previous landing site of Chang’e 3, she said.

Radar waves revealed various layers beneath the moon’s surface: grainy（ 颗粒状的）material, boulders（岩石）,and further layers of fine and coarse（粗糙的）particles. This information is helping scientists to gain new understanding of the moon’s history and formation, as well as volcanic activity and lunar impacts.

Yutu 2 is the longest﹣working rover（巡视器）on the moon, but it won’t last forever. China plans to launch the Chang’e 5 probe later this year, Xinhua News Agency reported. The spacecraft is expected to bring pieces of the moon back to Earth for closer study.

1.What can we learn about the Chang’e 4 probe?

A.It was the first to land on the moon’s near side.

B.It explored areas as wide as 1,770 kilometers.

C.Its signals could reach 40 meters beneath the moon’s surface.

A.It looks like a large hole.

B.It is about 6 millimeters thick.

C.It goes farther down than expected.

D.It is covered by boulders and fine and coarse particles.

3.According to the passage, why is the Chang’e 4 probe exploration is important?

A.It observed material beneath the moon’s surface which is helping scientists to know the moon better.

B.It has offered us relevant information on the near side of the moon.

C.It told scientists the landing site is very complex.

D.It revealed the surface material on the moon which is helpful to know the moon’s activity and impact.

4.What is the Chang’e 5 probe expected to do?

A.Explore the Von Karman crater.

B.Replace Yutu 2 to explore the moon.

C.Identify the moon’s various layers.

D.Bring lunar samples back to the Earth.

5.What is the text mainly about?

A.A history of Chinese lunar missions.

B.How Yutu 2 explored beneath the moon’s surface.

C.report on the Chang’e 4 probe’s findings.

D.A comparison of the Change 3 and 4 probes.

高三英语单项填空中等难度题查看答案及解析

On warm summer days with little or no wind, the air temperature in cities can be up to ten degrees higher than that of the surrounding countryside. This is a phenomenon commonly referred to as the “urban heat island” effect.

This phenomenon happens when pavement, buildings, and other infrastructure （基础设施） replace natural land cover. Large amounts of paved and dark colored surfaces—such as roofs, roads, and parking lots—absorb, rather than reflect, the sun’s heat, causing surface temperatures and overall ambient （周围的） air temperature to rise. Unlike soil, paved areas contribute to runoff, which means that as paved areas increase, the amount of water available for evaporation （蒸发） decreases. Moreover, urban areas have fewer trees and less natural vegetation which help to control the heat by providing shade and blocking solar radiation. The surfaces of leaves also provide water for evaporation which cools the air, further worsening the heat island effect.

In particular, during summer, more energy is required to cool the insides of building and for refrigeration, thereby creating additional heat output. This in turn leads to higher ambient air temperatures, which can also significantly increase the formation of urban smog in an area, degrading local air quality. Such a situation may directly affect public health with individuals more likely to suffer from heat exhaustion and the effects of asthma （哮喘）.

1.The underlined part in Paragraph 2 means ________.

A．Due to dark colored roads, urban areas are becoming hotter each year

B．Dark colored surfaces reflect the sun’s heat, causing air temperatures to rise

C．Because urban surfaces absorb heat, air and surface temperatures increase

D．Rising ambient air temperatures lead to urban surfaces absorbing more heat

2.Which of the following is not a cause of the urban heat island effect?

A．The lack of trees

B．The demand for refrigeration

C．The blocking of solar radiation

D．The construction of infrastructure.

3.The underlined word “degrading” most probably means ________.

A．ignoring　　 　　 B．improving

C．highlighting　 D．worsening

4.The passage is mainly developed by ________.

A．giving typical examples

B．following the time order

C．presenting the effect and analyzing the cause

D．analyzing a problem and seeking the solution

Why go to Madrid？

There may be a slight chill(寒冷) in the air, with temperatures staying around 15℃ in March, but Spain’s handsome capital is slowly starting to warm up. Even more attractive are the cultural events.

A new exhibition on the living and working spaces of Spain’s greatest artist, Picasso, has just opened in the studio at the Fundación Mapfre at Paseo de Recoletos 23. It runs until 11 May with rarely seen pieces borrowed from his family.

Later this summer, the 400th anniversary of the death of the Renaissance(文艺复兴) painter El Greco will be marked with an exciting exhibition at the Museo del Prado at Paseo del Prado from 24June to 5 October.

How to go?

The widest range of flights is offered by EasyJet—from Bristol, Edinburgh, Gatwick, Liverpool and Luton. British Airways and its sister airline Iberia combine forces from Heathrow and London City. Ryanair flies from Manchester and Stansted; Air Europa flies from Gatwick.

Barajas airport is 13km north-east of the city centre and is served by frequent trains on Metro line 8, but the shortest underground journey is a bit complex with at least one change at Nuevos Ministerios station and takes about 30 minutes. The fare to any station in the city centre is ∈4.50. The airport express bus runs every 15 to 35 minutes around the clock; ∈5 one way. It takes 40 minutes to reach the city centre. A taxi takes half the time. A flat rate of ∈30 covers most of central Madrid.

1.When will the exhibition about Picasso close?

A.On 23 March. B.On 11 May. C.On 24June. D.On 5 October.

2.Which airline operates flights from Manchester to Madrid?

A.EasyJet. B.Ryanair. C.Air Europa. D.British Airways.

3.What is the fastest way to reach central Madrid from Barajas airport?
