The passage suggests which of the following about the hypothetical discovery of an absence

of seasonal variations in oxygen 18 molecules？Ⅰ. It would not prove that certain dinosaurs were capable of regulating their temperatures internally.Ⅱ. One likely source of such a discovery would come from annual growth bands of dinosaur teeth.Ⅲ. The fact that no biotechnology yet exists to elucidate thermoregulation biochemistry proves such a discovery is impossible.Ⅳ. The discovery would be profound, because oxygen 18 is only found in fossil records where there is seasonal variation.

A．Ⅰ and Ⅱ only

B．Ⅱ and Ⅲ only

C．Ⅲ and Ⅳ only

D．Ⅰand Ⅳ only

E．Ⅱ, Ⅲ, and Ⅳ only

Passage Two Questions 6 to 10 are based on the following passage. On Jan. 9, 2007, Steve Jobs formally announced Apple’s “revolutionary mobile phone” — a device that combined the functionality of an iPod, phone and Internet communication into a single unit, navigated by touch. It was a huge milestone in the development of smartphones, which are now owned by a majority of American adults and are increasingly common across the globe. As smartphones have multiplied, so have questions about their impact on how we live and how we work. Often the advantages of convenient, mobile technology are both obvious and taken for granted, leaving more subtle topics for concerned discussion: Are smartphones disturbing children’s sleep? Is an inability to get away from work having a negative impact on health? And what are the implications for privacy? But today, on the 10th anniversary of the iPhone, let’s take a moment to consider a less obvious advantage: the potential for smartphone technology to revolutionize behavioral science. That’s because, for the first time in human history, a large proportion of the species is in continuous contact with technology that can record key features of an individual’s behavior and environment. Researchers have already begun to use smartphones in social scientific research, either to query people regularly as they engage in their normal lives or to record activity using the device’s built-in sensors. These studies are confirming, challenging and extending what’s been found using more traditional approaches, in which people report how they behaved in real life or participate in relatively short and artificial laboratory-based tasks. Such studies are just first steps. As more data are collected and methods for analysis improve, researchers will be in a better position to identify how different experiences, behaviors and environments relate to each other and evolve over time, with the potential to improve people’s productivity and wellbeing in a variety of domains. Beyond revealing population-wide patterns, the right combination of data and analysis can also help individuals identify unique characteristics of their own behavior, including conditions that could indicate the need for some form of intervention — such as an unusual increase in behaviors that signal a period of depression. Smartphone-based data collection comes at an appropriate time in the evolution of psychological science. Today, the field is in transition, moving away from a focus on laboratory studies with undergraduate participants towards more complex, real-world situations studied with more diverse groups of people. Smartphones offer new tools for achieving these ambitions, providing rich data about everyday behaviors in a variety of contexts. So here’s another way in which smartphones might transform the way we live and work: by offering insights into human psychology and behavior and, thus, supporting smarter social science. 10. What do we learn about current psychological studies?

A、They are going through a period of painful transition.

B、They are increasingly focused on real-life situations.

C、They are conducted in a more rigorous manner.

D、They are mainly targeted towards undergraduates.

According to the passage, scientists have concluded which of the following from the discovery of the large amount of deuterium found in comets？

C．It is likely that comets contain less Xenon than meteorites do.

D．Given the low level of deuterium in the waters of Earth's oceans, comets cannot be its sole source.

E．Comets now play a greater role in the creation of the Earth's oceans than was previously thought.

Passage Two Questions 16 to 20 are based on the following passage. Biologists believe that love is fundamentally a biological rather than a cultural construct. That is because the capacity for love is found in all human cultures and similar behavior is found in some other animals. But what does science have to say about the notion of love at first sight? In recent years the ability to watch the brain in action has offered a wealth of insight into the mechanics of love. Researchers have shown that when a person falls in love a dozen different parts of the brain work together to release chemicals that trigger feelings of euphoria (愉快), bonding and excitement. It has also been shown that the unconditional love between a mother and a child is associated with activity in different regions of the brain from those associated with sexual, pair-bonding love. In fact, the desires, motivations and withdrawals involved in love have a great deal in common with addiction. What this means is that one special person can become chemically rewarding to the brain of another. Love at first sight, then, is only possible if the mechanism for generating long-term attachment can be triggered quickly. There are signs that it can be. One line of evidence is that people are able to decide within a fraction of a second how attractive they find another person. Ayala, a psychologist at Ben-Gurion University, also found in a survey that a small fraction (11%) of people in long-term relationships said that they began with love at first sight. It is also clear that some couples need to form their bonds over a longer period, and popular culture tells many tales of friends who become lovers. One might also speculate that if a person is looking for a partner with traits that cannot be quantified instantly, such as compassion, intellect or a good sense of humor, then it would be hard to form a relationship on the basis of love at first sight. Those more concerned only with visual appearances, though, might find this easier. So it appears that love at first sight exists, but is not a very common basis for long-term relationships. 16. How do biologists regard love?

A、It has nothing to do with culture.

B、It is basically a biological concept.

C、It is only seen in some human cultures.

D、It cannot be explained by science.
