陈虎平老师也推出了新的36套，我发现部分文章是新加进去的，所以网上也没有讲解看，所以想征集各路高手一起把新阅读拿下、吃透。现在我的打算是把自己碰到的新文章发上来大家一起讨论，不知道大家有没有好的建议，我们可以集思广益，换别的方法也好，如果要厉害的小伙伴愿意主持那更好不过了，我现在水平还比较菜。希望我们一起喜刷刷，喜刷刷，拿下阅读！！！

第一篇先发上来，明天写答案

It has been known for many decades that the appearance
of sunspots is roughly periodic, with an average cycle of
eleven years. Moreover, the incidence of solar flares and
the flux of solar cosmic rays, ultraviolet radiation, and
5x-radiation all vary directly with the sunspot cycle. But
after more than a century of investigation, the relation
of these and other phenomena, known collectively as the
solar-activity cycle, to terrestrial weather and climate
remains unclear. For example, the sunspot cycle and
10the allied magnetic- polarity cycle have been linked to
periodicities discerned in records of such variables
as rainfall, temperature, and winds. Invariably,however,
the relation is weak, and commonly of dubious
statistical significance.
15 Effects of solar variability over longer terms have
also been sought. The absence of recorded sunspot
activity in the notes kept by Europeanobserver
in the late seventeenth and early eighteenth
centuries has led some scholars to postulate a brief
20cessation of sunspot activity at that time (a period called
the Maunder minimum). The Maunder minimum has
been linked to a span of unusual cold in Europe extending
from the sixteenth to the early nineteenth centuries.
The reality of the Maunder minimum has yet to be
25established, however, especially since the records that
Chinese naked-eye observers of solar activity made
at that time appear to contradict it. Scientists have
also sought evidence of long-term solar periodicities
by examining indirect climatological data, such as fossil
30records of the thickness of ancient tree rings.
These studies, however, failed to link unequivocally
terrestrial climate and the solar-activity cycle, or even
to confirm the cycle‘s past existence.




6. It can be inferred from the passage that studies
attempting to use tree-ring thickness to locate possible
links between solar periodicity and terrestrial climate
are based on which of the following assumptions?
(A) The solar-activity cycle existed in its present form
during the time period in which the tree rings grew.
(B) The biological mechanisms causing tree growt
h are unaffected by short-term weather patterns.
(C) Average tree-ring thickness varies from species
to species.
(D) Tree-ring thicknesses reflect changes in terrestrial climate.

(E) Both terrestrial climate and the solar-activity cycle
randomly affect tree-ring thickness

7. According to the passage, late seventeenth and early
eighteenth-century Chinese records are important for
which of the following reasons?
(A) They suggest that the data on which the Maunder
minimum was predicated were incorrect.
(B) They suggest that the Maunder minimum cannot be
related to climate.
(C) They suggest that the Maunder minimum might be
valid only for Europe.
(D) They establish the existence of a span of unusually
cold weather worldwide at the time of the Maunder minimum.
(E) They establish that solar activity at the time of the
Maunder minimum did not significantly vary from its present pattern.

6 D 细节题
由tree-ring thickness 定位到了第二段的末尾处，再由这里的examing climatological data 进一步可知是与climate相关，锁定选项D
7 A 作用题
一般作用题就是找改句话的逻辑上次（不一定是前一句话），这里就是The reality of the Maunder minimum has yet to be established,所以锁定选项A
