問題詳情：
Earlier this year, China achieved a new milestone (里程碑) in space research. On January 3, 2019, Chang'e-4 became the first lunar probe (月球探測器) in history to successfully land on the far side of the moon.
The Earth's gravity (重力) slows the moon's rotation (自轉), matching it to the speed of its orbit (公轉). Therefore, the far side of the moon is almost "dark" and has never been seen. It's this sense of the unknown that makes the far side of the moon such an interesting place for scientific and space research. Being blown by solar (太陽的) winds, the far side may have the special minerals (礦物質 ). For this reason, Chang'e-4 will study the effect of solar winds on the lunar surface and any mineral found by the spacecraft. Chang'e-4 is also carrying flower seeds, potatoes and silkworm eggs to see whether life is possible on the moon. If it is, then the moon will become a possible choice for space travel in the future.
However, research of the "dark" side isn't easy. As the far side is blocked（阻斷） off from us, radio noise coming off Earth is also blocked. This is why China's relay satellite (中繼衞星) Queqiao was sent up in May, 2018. Thanks to Queqiao, the communication problem between
Earth and Chang'e-4 has been well solved.
Power supply (電源供應) is also a challenge to the task. Chang'e-4 gets energy from the sun through its solar panels. As we know, a lunar day has the length (長度) of 28 Earth days. After Chang'e-4 was sent up on December 8, 2018, it took the probe over 20 days to orbit the moon to be in a position to be able to land in moon daylight and use its solar panels.
Luckily, everything goes well, Chang'e-4 has worked on the "dark" side for over 5 months. It has sent back many photos of the far side of the moon and has been used to carry out some scientific experiments.
The New York Times used the word "groundbreaking" to praise the task and wrote that "it will offer help to the history and development of the moon".
22. When was Chang'e-4 sent up?
A. In May, 2018. B. On December 8, 2018.
C. On January 3, 2019. D. The passage doesn't tell us.
23. The main tasks of Chang'e-4 don't include ___________________.
A. studying if life is possible on the moon
B. studying the effect of solar winds on the lunar surface
C. solving the communication problem between Earth and other probes
D. researching any mineral found by the spacecraft
24. The meaning of the underlined word "groundbreaking" in the last paragraph is the closest to
"________________".
A. harmful B. unpredictable C. risky D. pioneering
25. According to the passage, which of the following statements is NOT true?
A. Chang’e-4 has sent back many photos of the far side of the moon.
B. A lunar day has the length of 28 Earth days
C. China's relay satellite Queqiao was sent up in order to offer power supply to probes.
D. Chang'e-4 is the first lunar probe in history that has successfully landed on the "dark" side of the moon.
【回答】
22.B
【解析】細節理解題。根據Chang'e-4 was sent up on December 8, 2018可知，嫦娥四號是2018年12月8日發*的，故選B。
23.C
【解析】細節理解題。根據Chang'e-4 is also carrying flower seeds, potatoes and silkworm eggs to see whether life is possible on the moon可知，嫦娥四號也攜帶着花的種子、土豆、蠶卵看觀察在月球上是否有生命的可能，排除A；根據For this reason, Chang'e-4 will study the effect of solar winds on the lunar surface and any mineral found by the spacecraft可知，因此，嫦娥四號將研究太陽風對月球表面的影響和通過航天器發現礦物質，排除B和D；根據Thanks to Queqiao, the communication problem between Earth and Chang'e-4 has been well solved可知，多虧了鵲橋，地球和嫦娥四號的交流問題解決了，所以鵲橋解決的是交流問題，故選C。
24.D
【解析】詞義猜測題。根據The New York Times used the word "groundbreaking" to praise the task and wrote that "it will offer help to the history and development of the moon"以及On January 3, 2019, Chang'e-4 became the first lunar probe (月球探測器) in history to successfully land on the far side of the moon可知，嫦娥四號是第一個登錄月球背面的探測器，所以《紐約時報》用“開創*”一詞來讚揚這項任務，並寫道“它將為月球的歷史和發展提供幫助。故選D。
25.C
【解析】細節理解題。根據It has sent back many photos of the far side of the moon and has been used to carry out some scientific experiments可知，它也發送回來許多地球背面的照片，排除A；根據As we know, a lunar day has the length (長度) of 28 Earth days. After Chang'e-4 was sent up on December 8, 2018可知，月球上一天的長度相當於地球上28天，排除B；根據On January 3, 2019, Chang'e-4 became the first lunar probe (月球探測器) in history to successfully land on the far side of the moon可知，嫦娥四號是歷史上第一個登錄月球背面的探測器，排除D；根據Thanks to Queqiao, the communication problem between Earth and Chang'e-4 has been well solved可知，中繼衞星鵲橋的主要任務是讓地球和嫦娥四號取得聯繫，故選C。
