In the dark forests ________ some large enough to hold several English towns.
A. stand many lakes B. lie many lakes
C. many lakes lie D. many lakes stand
【詳解】本題考查倒裝結構，完全倒裝。同時stand 和lie的區別。stand是突出的，lie是平躺的，湖不可能是突出的，所以此題應該選擇lie。

In the long discussion of water on the Moon, a new study contradicts(與……相矛盾)) some recent reports that say the Moon had water at the time of its formation. A group of researchers reported in the journal Science that when the Moon was created, some 4.5 billion years ago, there was not much hydrogen(氫氣) on it, and therefore no water.
The researchers surveyed and evaluated this by analyzing chlorine isotopes（氯同位素） found in lunar rock samples from Apollo missions. The range of chlorine isotopes in lunar samples was 25 times that found in samples from Earth.
If the Moon had significant levels of hydrogen, as Earth did, this range would have been far less, said Zachary D Sharp, a scientist in the Department of Earth and Planetary Sciences at the University of new Mexico and the study’s lead authour.
The chlorine would have stuck together with hydrogen, forming compounds like hydrogen chloride, and escaped from the Moon’s surface, he said. The abundance of chlorine indicates a lack of hydrogen and water.
“ The amount of water on the Moon was too low for life to possibly have existed there,” he said.
Most scientists believe the Moon was formed when a large object stuck Earth, breaking off a chunk(a vast piece) that has since orbited Earth.
On Earth, goes one theory, water was released as steam form molten basalts(玄武巖) over time, eventually forming bodies of water.
“An understading of whether the Moon was dry or wet will help us understand how water appeared on Earth,” Dr Sharp said.
A new study indicates that _____ on the moorn.
A. there is plenty of water B. water is unlikely to exist
C. water existed in the past D. there is a little water now
The author would like to tell us ______ through the sixth paragraph.
A. why there is no water on the Moon B. how the Moon was formed
C. when the Earth struck the Moon D. where the Moon orbited
Which is NOT true according to the passage?
A. Zachary D. Sharp, a scientist of New Mexico was in charge of the new study.
B. Chlorine isotopes in lunar samples are 25 time larger than those on the Earth.
C. The more aboundant chloride, the shorter hydrogen and water.
D. The new study is benificial to understand how water appeared on Earth.
What can we learn from the passage?
A. There is enough water on the Earth.
B. Hydrogen chloride easily escaped from the Moon’s surface.
C. The Earth had significant levels of hydrogen.
D. Water on the Earth is directly from molten basalts.
