Passage 1 话题:城市垂直农业
阅读下面短文,从每题所给的A、B、C、D四个选项中选出最佳选项。
As urban populations keep expanding, traditional farmland is shrinking steadily. Conventional outdoor farming is easily affected by extreme weather, pests and seasonal changes. Vertical farming, which grows crops in multi‑layer indoor facilities, has arisen as a promising solution to city food supply pressure.
Inside high‑rise planting buildings, crops grow without natural soil. Instead, hydroponic systems deliver water and balanced nutrition directly to plant roots. LED lamps replace sunlight, providing customized light wavelengths suitable for different plant species. The whole production process is isolated from open‑air environment, so harmful insects and bad weather can hardly interfere with plant growth.
Vertical farming brings remarkable strengths. It greatly raises output per unit land area and cuts water consumption by a large margin. Local urban planting also shortens transportation chains and reduces carbon release caused by long‑distance food delivery. Even so, it is far from perfect. Continuous lighting and climate control require huge electric power. Besides, building such multi‑layer planting facilities demands high initial investment, limiting its large‑scale popularization.
Researchers are trying to lower energy costs by combining solar power with vertical farm systems. Experts remind readers that vertical farming is not meant to replace field agriculture. It serves as a valuable supplement, helping cities achieve partial self‑supply of fresh vegetables.
1. What is one advantage of vertical farming?
A. It completely gets rid of the need of electric power.
B. It improves output within limited land space.
C. It totally replaces traditional outdoor agriculture.
D. It requires no investment to set up facilities.

Passage 2 话题:极光背后的地磁扰动效应
阅读下面短文,从每题所给的A、B、C、D四个选项中选出最佳选项。
Most people regard auroras merely as breathtaking natural sights dancing near polar regions. Apart from visual beauty, auroras are signs of violent interactions between solar wind and Earth’s magnetic field. When massive charged particles from the sun rush toward our planet, they may trigger geomagnetic disturbances, bringing practical influences on human technological systems.
Under quiet conditions, Earth’s magnetic field forms protective barriers around the globe. Once powerful solar bursts arrive, large quantities of charged particles break part of the barrier. When these high‑energy particles collide with atmospheric gas molecules, colorful aurora lights come into being. Meanwhile, geomagnetic currents are produced deep underground.
Such underground currents are harmless to human bodies. Nevertheless, they may generate extra voltage inside long‑distance power grids and submarine communication cables. In serious cases, the unexpected voltage can damage power equipment and cause regional power failures. Satellite signals can also be disturbed, interfering with positioning and navigation services.
Scientists build monitoring networks to track solar activities and forecast intense geomagnetic storms. Their early warnings help power companies and satellite operators take protective measures. Though brilliant to watch, auroras remind humans that solar‑terrestrial activities can directly affect modern high‑tech infrastructure.
1. What causes the formation of auroras?
A. Gas collision with solar charged particles.
B. Light reflection from thick polar ice sheets.
C. Heat release from deep underground volcanoes.
D. Chemical reaction inside human‑made power grids.
2. What possible trouble may severe geomagnetic disturbances bring?
A. Direct physical injury to people living in polar zones.
B. Extra voltage threatening power‑grid equipment.
C. Complete disappearance of all polar ice cover.
D. Permanent rise of global average temperature.
3. What can we infer from the passage?
A. Human bodies will be severely hurt by underground geomagnetic currents.
B. Solar activities can exert influences on satellite navigation systems.
C. Scientists cannot get any information about solar bursts at present.
D. Aurora sightings will surely lead to large‑scale blackouts.
4. Which of the following is the best title for the text?
A. Aurora: More than a beautiful natural view
B. How polar ice shapes global climate patterns
C. Major causes of worldwide power shortages
D. Different ways to observe polar landscapes
Passage 3 话题:仿生流体减阻技术
阅读下面短文,从每题所给的A、B、C、D四个选项中选出最佳选项。
Ships and underwater vehicles consume huge amounts of energy fighting against water resistance during navigation. For a long time, engineers tried smooth surfaces to cut drag effects, yet the improvement remained limited. By studying marine creatures such as dolphins, researchers developed bionic drag‑reduction technology.
Dolphin skin possesses special micro‑groove structures. When water flows over its surface, these tiny grooves adjust fluid flow patterns and weaken violent turbulent swirls. As a result, water friction force drops greatly. Inspired by this biological feature, scientists have created artificial membrane material covered with similar micro‑grooves, which can be attached to ship hull surfaces.
Test results show that this bionic material can reduce water drag noticeably and therefore cut fuel consumption for ships. However, real‑world application meets challenges. Seawater carries algae, shellfish and other marine organisms. They easily stick to groove structures and cover micro‑patterns, making drag‑reduction effects disappear. Regular cleaning will increase extra operating costs.
Material scientists are now modifying the bionic membrane’s surface property to prevent marine organisms from attaching themselves. It is expected that the technology will serve shipping industry better after solving the anti‑fouling problem.
1. What is the function of micro‑grooves on dolphin skin?
A. Produce powerful driving force for fast swimming.
B. Adjust fluid flow and lower water friction resistance.
C. Help dolphins store large amounts of fat under skin.
D. Protect dolphins from attacks of ocean predators.
2. What will happen when sea creatures stick to artificial micro‑groove membranes?
A. Ships can swim at much higher speeds automatically.
B. The drag‑reduction function will lose its effect.
C. Friction force of seawater will become zero completely.
D. The membrane will dissolve quickly in salt seawater.
3. What can we infer about bionic drag‑reduction technology?
A. It works perfectly without any further improvement.
B. Marine organism attachment is one practical barrier.
C. It has been widely used in all land transportation.
D. Regular cleaning will decrease ships’ total costs.
4. What does the underlined word “turbulent” in Paragraph 2 mean?
A. violently‑changing
B. slow‑moving
C. crystal‑clear
D. ice‑covered
Passage 4 话题:古生物分子化石研究
阅读下面短文,从每题所给的A、B、C、D四个选项中选出最佳选项。
Traditional fossil research mainly depends on hard remains including bones and shells. Soft tissues such as skin, muscle and blood usually break down rapidly after creatures die, leaving almost no trace. In recent years, paleontologists have made breakthroughs in studying ancient molecular fossils preserved inside hard fossils.
Under special burial conditions, small parts of biomolecules like protein can survive for millions of years within mineralized bone. Though original complete cells are long gone, these fragmentary molecular remains carry biological information of ancient creatures. Scientists can extract and analyze them to figure out evolutionary relationships among extinct species.
Molecular fossil study provides new evidence for biological evolution. Still, the work faces great difficulties. Ancient biomolecules are extremely fragile. Heat, moisture and bacteria will speed up their destruction. Only samples experiencing mild temperature changes can keep molecular signals. Besides, modern pollution may mix foreign molecules into ancient samples and mislead research conclusions.
Strict sample selection and careful experimental operations are required for such studies. Experts point out that molecular fossils will not replace bone‑based fossil research. Combined analysis of hard remains and molecular evidence offers a more comprehensive understanding of ancient life on Earth.
1. What material do traditional fossil studies mainly rely on?
A. Ancient skin and muscle tissues.
B. Preserved ancient blood samples.
C. Hard remains like bones and shells.
D. Complete original ancient animal cells.
