“The main advantage of microlensing is the signals for lowmass planets:They’re not weak signals.They’re just rare,” Bennett of the University of Notre Dame in Indiana said by telephone.“If there happens to be a straight line between a foreground star with its planet and the background source star,then you’re able to detect that planet.”
5.The underlined word “detected” in Paragraph 1 probably means “
”.
A.discovered
B.destroyed
C.created
D.searched
答案 A
解析 词义猜测题。由第一段第一句“A new planethunting technique has detected the most earthlike planet yet around a star other than our sun...”及第三段第一句中的“The team has discovered the most...”可知,这里detect与discover的含义相同,指的是“探测、发现”。故选A。
6.The author’s purpose in writing this passage is to
.
A.prove that scientists have a lot of difficulties in doing scientific research
B.explain why this planet moves around a star like our sun
C.teach the readers some basic knowledge about the universe
