1 . More than 80 percent of global heat is absorbed by the ocean, which has a massive capacity to store and give off heat. High sea-surface temperatures are causing long-term damage to coral reefs (珊瑚礁). Corals are dying. The IPCC (政府间气候变化专门委员会) projects that up to 90 percent of coral reefs could disappear if global warming reaches 1.5℃. Another reason corals are in trouble is because of ocean acidification. Higher carbon dioxide levels have shift ed the chemistry of the ocean, making it more acidic, and corals and sea creatures have trouble growing in acidic conditions.

When ocean water warms, it expands in volume. This is a major cause of the rise in sea levels, along with the water added to the ocean by the melting of land-based glaciers (冰川). The sea level has risen by an average of 20 centimeters since the late 19th century, and the research by scientists studying the last 25 years of satellite data found that the ocean water is rising faster and faster. If it continues at its current rate, the rise in sea level by 2100 will be more than double the current estimates. Sea level rise leads to the destruction of coastal wetlands, flooding and damage to water ecosystems.

Temperature and precipitation (沉淀) are key elements of climate. A warmer climate means that more water rises from both the land and ocean, and a warmer atmosphere holds more of that water. Scientists have noticed that there are more heavy rainfall events. Additionally, higher water temperature in streams, lakes, and rivers lead to lower levels of dissolved oxygen in the water, which impacts the survival and populations of fish and other sea life.

Especially troubling are the extreme weather events that are happening more often around the world. Hurricanes are ramping up in intensity, particularly in North Atlantic. The year 2017 was a busy one for Atlantic hurricanes. Meanwhile, in the western United States, the state of California has had record-setting drought conditions, which began in 2012.

7 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

In China, even for the most accomplished chefs, cooking     1     (involve) improvising with the ingredients (原料) on hand: feel and taste. For the Chinese, the idea of exact time and amounts in cooking is an alien concept. In fact, times and measuring cups won’t     2     (find) in a traditional Chinese kitchen. Nor will a Chinese cook asked     3     he or she makes a particular dish respond with clear     4     (quantity) of ingredients and an exact cooking time, for such concrete instructions are almost nonexistent in the world of Chinese cuisine.

    5     (make) Chinese food can be very time consuming. One reason is     6     the preparation before the actual cooking takes time, as ingredients for the same dish are     7     (typical) cut into uniform shapes, and preferably into bite-sized pieces. Chinese cooking employs different methods according to the nature of the ingredients, the     8     (long) of cooking time, and the degree of heat. The major emphasis, though, is on enhancing the natural flavor of ingredients, as well as retaining nutrients.

Almost every Chinese kitchen has     9     bamboo steamer. In this method, food s are put in the steamer above boiling water. This technique preserves the colors, flavors, and nutrients of the food. A good cook knows which techniques to use     10     (combine) the natural flavors of the ingredients for the best taste and nutrition.

8 . At first, the grains of rice that Ingo Potrykus held in his fingers did not seem at all _________, but inside, these grains were not white, as ordinary rice is, but a very pale yellow — thanks to beta-carotene (胡萝卜素), a building block for vitamin A.

For more than a decade Potrykus had _________ creating a golden rice that could improve the lives of millions of the poorest people in the world, strengthening their eyesight and their _________ disease.

_________ imagining golden rice was one thing and creating one quite another. Year after year, Potrykus and his colleagues ran into one _________ after another until success finally came in the spring of 1999.

At that point, he tackled an even greater challenge. The golden grains _________ pieces of DNA borrowed from bacteria and flowers. It was what some would call Frankenfood, a product of genetic engineering. As such, it _________ a web of hopes and fears.

The debate began the moment genetically engineered crops (GM crops) were first sold in the 1990s, and it has _________ ever since. First to start major protests against biotechnology were European environmentalists and consumer-advocacy groups. They were soon followed by their U.S. counterparts (相对应的人事物).

The hostility is _________. Most of the GM crops __________ so far have been developed to produce a plant that is not harmed by chemicals used to kill weeds (杂草) in the fields. These genetically engineered crops are often sold by the same large, multinational corporations that __________ the weed-killing chemicals that farmers spray on their fields. Consumers have become suspicious (怀疑的).

The benefits did seem small __________ golden rice was developed. It is the first strong example of a GM crop that may __________ not just the farmers who grow it but also the consumers who eat it. In this case, those include at least a million children who die every year because they are weakened by vitamin-A deficiency (缺乏) and an additional 350,000 who go blind.

Many people __________ poverty and hunger look at golden rice and see it as evidence that GM crops can be made to serve the greater public good. They see a critical role for GM crops in feeding the world’s ever-increasing population. As former U.S. President Jimmy Carter put it, “Responsible biotechnology is not the enemy; __________ is.”

10 . A fourth color might be added to traffic lights to better realize the potential of self-driving vehicles, as stated in a recent paper by researchers at North Carolina State University in the US.

Autonomous vehicles can do more than just drive-they are able to sense their surroundings and upload information. A shared network gives orders to stop at a crossing based on traffic conditions.

The added white lights would be used to signal to human drivers that autonomous vehicles are managing the upcoming traffic flow intelligently. Drivers don’t have to check the traditional lights if the white one is on. “The white lights will tell human drivers to simply follow the car in front of them,” one of the study authors Ali Hajbabaie told the university’s website.

Simulated (模拟的) models showed that autonomous vehicles were able to improve traffic flow on their own. Introducing the white light also has a positive effect on reducing fuel consumption. The higher the percentage of autonomous vehicles at a crossing, the faster the traffic moves, reducing about 40 to 99 percent of the total delay time.

What kind of infrastructure (基础设施) is needed as self-driving technology thrives? In an interview with China Surveying and Mapping magazine, Liu Jingnan at the Chinese Academy of Engineering shared his answers.

To begin with, the vehicle’s network that collects data about the environment and shares the data with other vehicles needs to be intelligent. High-precision maps are needed for autonomous vehicles to plan routes in detail. They can provide both updated information on traditional maps and real-time changes, such as accidents.

For example, when driving around a curve, the navigation (导航) system in the vehicle needs to calculate the safe speed based on the map’s information. And if the area is foggy, the network has to alarm the other cars to slow down.

Other elements on the road need to be upgraded too. For example, road markings should be precise and readable for machines. Sensors should be built on sidewalks and roads to allow vehicles to predict potentially dangerous situations.

1. What is the purpose of adding a white light to traffic lights?

A．To signal to self-driving cars when to stop.

B．To help driverless cars assess traffic conditions.

C．To tell human drivers to go after the cars in front.

D．To signal to human drivers to pass the cars ahead.

2. According to the article, what effect would the introduction of self-driving cars bring about?

A．Increased road safety.	B．Reduced fuel efficiency.
C．Less time stuck in traffic.	D．Unpredictable traffic patterns.

3. What is a function of high-precision maps in self-driving technology?

A．To calculate a safe speed for vehicles.	B．To provide real-time weather updates.
C．To plan routes for autonomous vehicles.	D．To offer real-time data on road conditions.

4. What does the author intend to prove in the second-to-last paragraph?

A．The advantages of autonomous vehicles.

B．The role of the navigation system in self-driving cars.

C．The application of the infrastructure in self-driving cars.

D．The efficiency of self-driving cars handling emergencies.
