Let’s get access to two passages and analyze their categories.
Let’s move on to Passage 1.
1. Pay attention to the key words and anaylze which category of this expositon.
Research report.
2. What’s the discourse structure
Discourse structure

28. What can we learn about the new sensor
A. It is invented by a local community.
B. It can quickly assess soil condition.
C. It is difficult to apply in distant areas.
D. It helps collect a number of soil samples.
In parts of Tanzania, soils are disappearing. A combination of climate change and socioeconomic stresses has led to soil ending into nearby rivers and lakes.
Recognizing the threat, the local community set up an environmental committee to allow strategic decision- making for soil restoration. They worked with researchers led by Will Blake at the University of Plymouth, who are experimenting with a gamma ray (伽马射线) sensor that can be easy to carry. It can make a judgement about the health of the soil in several minutes, while the traditional approach is done by taking a small number of samples for lab analysis and takes more time. The community identified areas where the soil was severely reduced, and so excluded their cattle. With the pressure removed, the land re-greened quickly and the soil began to recover.

Tip1 ：同义替换
quickly=in several minutes
assess=judgement
soil condition= the health of the soil
29. Why does Blake recommend “mutual learning”
A. To share data in the new research.
B. To develop a sustainable solution.
C. To remove the farmers’ burden.
D. To popularize sensor technology.
Blake emphasizes that the technology is only half the story. Scientists helicoptering in and offering solutions doesn’t work, partly because it ignores the autonomy of the farmers themselves and their extensive local environmental knowledge. Instead, Blake recommends“mutual learning”, in which different groups learn from each other and talk openly.
With the advancement of this cooperative approach, some farmers made dramatic changes.“ During past seasons, I used to get 4 — 5 bags of com per acre using improved varieties of seeds and intensive use of chemical fertilizers (肥料),” one reported. After scanning his soils, he switched to natural ones and intercropping between corn and beans, in an attempt to increase the soil quality and agriculture productivity.“ Now I am getting 7 — 9 bags of com in the same piece of land”.

① Digital devices have reduced our attention spans to the point that they’re shorter than that of a goldfish. The blue light they send out disturbs our sleep. Most worryingly of all, smartphones are damaging the mental health of the young. All things considered, in today’s world, digital technologies are a blight. Right
② Not so fast, says psychologist Etchells, a professor of psychology and science communication in the U. K., in his new book, Unlocked. Contrary to the numerous research studies on the seemingly undeniable harm of screen time on human health, Etchells argues that the evidence is weak.
③ Take the literature on screen time and mental health for example. Most of the previous studies, Etchells points out, take data from large surveys and find that people who spend more time on screen-based activities are more likely to report poor mental health. However, observational studies like these fall victim to the classic experimental issue — correlation does not imply causation. Instead of time spent on a smartphone causing mental health issues, it could be that mental health issues cause people to spend more time on their phones, or both phone usage and poor mental health could be caused by a third factor, such as loneliness.
④ In Unlocked, Etchells’ historical moral panic comparison of choice is the cancellation of the paper tax in the U. K. in 1861, after which some worried that women, children and working classes “needed to be ‘protected’ from a flood of trash literature.” But there have been many others throughout history: from people in Ancient Greece wondering what damage writing might do, to fears over “radio addiction,” to concerns that TV might promote violent behavior. This can be cause for doubts but not for dismissal, says Etchells.
⑤ With lawmakers around the world starting to propose laws that would significantly impact the way people use their digital devices, Etchells stresses that any baseless action could fail or even backfire and that overstated public discourse can actually let the technology industry off the hook.
