What really killed the dinosaurs?Lingering doubts about the cause of a mass extinction are put to rest
1.Main ideas:
Toxic and climate-changing gases from volcano eruptions are the underlying cause of the mass extinction of dinosaurs.
2.Structure
Common believe
New evidence
Elaborate on data
Explian the link between toxic, climate-changing gases from volcano and dinosaur extinction.
3.Sentences
And modelling suggests the planet would have been a pretty uncomfortable place for quite some time afterwards, with ejecta suspended in the atmosphere blotting out the sun, and acid rain changing the chemical composition of the oceans.
4.Vocabulary
blot out=cover/hide
ambient temperature=the temperature of the surrounding area
holdout=someone who refuses to agree or act with other people

The search for dark matter in the recent majestic universe
1.Main ideas:
Dark matter is not made of protons, neutrons and neutrinos, which was a candidate, but created from supersymmetry, one of the “cold” dark matter, among which neutralino is the lightest particle.
2.Structure
Dark matter is not made of protons, neutrons and neutrinos.
The best fit to the astronomical observations involves “cold’ dark matter.
Supersymmetry, one of the “cold” dark matter, is the best known candidate
Neutralino, the lightest particle from Supersymmetry, is one of substances that fashion dark matter.
3.Sentences
Those calculations have been corroborated by measurements of primordial hydrogen, helium and lithium in the universe.
4.Vocabulary
primordial=primeval=very ancient
fleet-footed=able to run fast
amalgam= mixture
photon=a particle of light.

Bonus
1.Main ideas:
Territoriality is rooted in human genes, whereas other species whose population is not affected by limiting resources do not evolve a hereditary response.
2.Structure
Introduction by a phenomenon.
The hypothesis that some species has a territorial defense while others don’t.
Humanity is decidedly a territorial species
3.Sentences
The theoretical explanation is that individuals hereditarily are predisposed to defend private resources.
4.Vocabulary
