Is there link between humans and climate change or not? This question was first studied in the early 1900s. Since then, many scientists have thought that our actions do make a difference. In 1997, the Kyoto Protocol explained our role in the Earth’s changing atmosphere and set international limits for gas emissions(排放) from 2008 to 2012. Some countries have decided to continue these reductions until 2020. More recently, the Paris Agreement, stuck by nearly 200 countries, also aims to limit global warming. But just now how much warmer it will get depends on how deeply countries cut carbon emissions.

1.It can be concluded from paragraph 1 that ________.

A. the problem of global warming will have been quite solved by 2020

B. gas emissions have been effectively reduced in developed countries

C. the Paris Agreements is more influential than the Kyoto Protocol

D. humans have made continuous efforts to slow down global warming

2.If nations could only keep the initial promises of the Paris Agreement, what would happen by the year 2100?

A. The human population would increase by one third.

B. Little over 50% of all species would still exist.

C. Nations would not need to tighten their emissions targets.

D. The Agreement’s minimum goal would not be reached.

3.If those island nations not far above sea level are to survive, the maximum temperature rise, since the start of the industrial age, should be_______.

A. 0.8℃            B. 1.5℃            C. 2℃            D. 3.5℃

This is how much temperatures would rise by 2100 even if nations live up to the initial Paris promises to reduce carbon emissions;this rise could still put coastal cities under water and drive over half of all species to extinction.

To meet this minimum goal,the Agreement requires countries to tighten emissions targets every five years.Even this increase could sink some islands,worsen drought and drive a decline of up to a third in the number of species.

This is the most ambitious goal for temperature rise set by the Paris Agreement,after a push by low-lying island nations like Kiribati,which say limiting temperature rise to 1.5℃ could save them from sinking.

This is how much temperatures have risen since the industrial age began,putting us 40% of the way to the 2℃ point.

The baseline here is average global temperature before the start of the industrial age.

It’s true that quite a few most respected scientific authorities have confirmed that the world is becoming hotter and hotter. There’s also strong evidence that humans are contributing to the warming. Countless recent reports have proved the same thing. For instance, a 2010 summary about the climate science by the Royal Society noted that: “The global warming over the last half-century has been caused mainly by human activity.”

You may not believe that humans could change the planet’s climate, but the basic science is well understood. Each year, billions of tons of greenhouse gases are released into the atmosphere because of human activity. As has been known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible blanket.

Of course, the earth’s climate has always been changing due to “natural” factors such as volcanic eruption or changes in solar, or cycles concerning the Earth’s going around the sun. According to the scientific research, however, the warming observed by now matches the pattern of warming we would expect from a build-up of greenhouse gas in the atmosphere—not the warming we would expect from other possible causes.

Even if scientists did discover another reasonable explanation for the warming recorded so far, that would give birth to a difficult question. As Robert Henson puts it: “If some newly discovered factor is to blame for the climate change, then why aren’t carbon dioxide and the other greenhouse gases producing the warming that basic physics tells us they should be?”

The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths — one with human influence and one without. That obviously isn’t possible, and so most scientists are careful not to state human influence as an absolute certainty.

1.The text is developed by ________.

A.giving typical examples

B.following the order of space

C.comparing and finding differences

D.analyzing a theory and arguing it

2.Which of the following statements is right according to the passage?

A.Few scientific authorities have confirmed the existence of global warming.

B.Greenhouse gases prevent heat in the atmosphere from escaping to space.

C.Some new factors for the climate change have been discovered by scientists.

D.Scientists are absolutely sure about the human influence on the earth’s climate.

3.The underline word “identical” in the last paragraph probably means ________.

A.exactly the same B.totally different

C.extremely important D.partly independent

4.Which of the following can be the best title?

A.Are Humans Definitely Causing Global Warming?

B.Are All the Scientists Really Scientific?

C.Where Is Global Warming Leading Us to?

D.What’s the Relation of Global Warming and Greenhouse Gases?

Most of Bangladesh is at or below sea level. Rising seawaters linked to climate change has severely affected the country. High water from storms in coastal areas also adds salt to soil. The land is becoming salty. Crops are less productive and many areas of cropland in the country are becoming unfit for farming. These are big problems for the small country. More than 155 million people live in Bangladesh. Growing crops is the most common way Bangladeshis support themselves.

To find a way out, farmers in the country are learning to grow vegetables in so-called “vertical gardens”. The soil in these gardens is better because heavy rains have removed much of the salt.

A vertical garden is easy to make. Villagers fill containers with good soil and natural fertilizers. They put the containers on bricks so they are off the ground. They add pieces of the bricks to the soil to help water flow and drain(排水).

The farmers cut small holes into the sides of the containers. This permits vegetables with short roots a place to grow. Vegetables with long roots grow on top of the container. One bag of soil can produce up to eight kilograms of vegetables in one season.

The farmers also grow vegetables in containers made from large, thin pieces of plastic supported by bamboo. This “vertical tower” measures more than a meter wide. Each of these towers can produce more than 100 kilograms of vegetables. It costs about $12-S13 to build.

1.What is mentioned as a big problem for Bangladesh?

A. Severe climate conditions.

B. Too many people to support.

C. Lack of enough fresh water.

D. Reduced crop productivity.

2.Which mainly makes vegetable growing in vertical gardens successful?

A. Places in the soil for roots.

B. Heavy rains kept in the soil.

C. The good soil with little salt.

D. Brick pieces added to the soil.

3.What does the underlined word “they” in Paragraph 3 refer to?

A. Bricks.　　 B. Fertilizers.　　 C. Villagers.　　 D. Containers.

4.What can we infer about the vertical tower?

A. It is off the ground.

B. It drains very improperly.

C. It uses bamboo for containers.

D. It is unfit for growing vegetables.

The African Continent has various habitat types, but savanna (热带草原) ecosystems cover approximately half. And where there is savanna, there is fire. "It's an important part of the ecology of the system," says University of Liverpool ecologist James R Probert. Burning allows grasses to take the lead by keeping taller bushes from occupying the land, Loss of grasses could push out species such as wildebeest (牛 羚 ), which are famous for their splendid annual migration.

A decade ago researchers put decreasing fires within Tanzania's Serengeti National Park down to the recovery of wildebeest population following an epidemic of rinderpest, a viral disease. When millions of wildebeest feed on grass, they remove fuel from the land, making fire less frequent and less severe.

But Probert and his colleagues found that even after wildebeest populations had stabilized by the mid-1990s, fires continued to decrease in the same area. Their analysis of satellite data showed that the region experienced a 40 percent reduction in wildfires between 2001 and 2014- in line with dramatic increases in farm animals in the area.

If you have lots of farm animals eating the grass, then you have less fire. That’s well known Probert says. "But I don’t think anybody had realized the degree of the decline in fire and linked it to farm animals before.”

This is a really interesting pattern, "says University of Guelph biologist John Fryxell, who was not involved in the study. He cautions, however, that 15 years' worth of data is still a fairly small amount of information from which to draw final conclusions. "What a short-term connection like that suggests is that there's something interesting here that could provide the grounds for a deeper experimental analysis, "he adds. That research could include artificially controlling fire frequency or grazing intensity (放牧强度) in certain areas and then monitoring the land's response over time.

1.What do we know about fires in savanna?

A.They only happen once in a decade.

B.They are harmful to the growth of grasses.

C.They help keep the balance of the ecosystem.

D.They guarantee the leading position of taller bushes.

2.According to Probert, what led to decreasing fires?

A.The spread of a disease. B.The increase in farm animals.

C.The change of the climate. D.The stability of wildebeest population.

3.What does John think of Probert's study?

A.It might help recover the land in savanna.

B.It could lead to further studies on savanna fire.

C.It has proven the link between fires and grasses.

D.It offers enough information for final conclusions.

4.What is the best title for the text?

A.Savanna Ecosystem. B.No More Farm Animals

C.Eating Away Fire. D.Controlling Wildfires

Have you ever wondered why there are so many skin colors in the world? Do you know why people living in particular areas usually have a certain color? Biology and history are the two reasons for this.

Skin contains something called melanin, which determines a person’s skin color. The more melanin a person has, the darker his or her skin will be. The amount of and the production of melanin are controlled by genetics, but can be affected by other things, such as sunlight. If a person lives in a place with less sunlight, a person’s body will produce less melanin, making the skin lighter.

Skin color is also affected by another source ---- vitamin D. humans all need vitamin D to build bones. People can get it by eating foods such as fish and milk, or from sunlight, so sunlight absorbed by melanin cannot be used for vitamin D production. Therefore, a dark—skinned person will produce less vitamin D than a light—skinned person when they received the same amount of sunlight.

The connection between vitamin D production and skin color is clear when we look at evolution. The earliest humans lived in Africa, their dark skin produced less vitamin D because of their dark skin. As a result, their skin made less melanin, so they could get enough sunlight to produce vitamin D. their skin gradually got lighter and they lost hair. Now, people living in areas with strong sunlight like Africa, have darker skin, while people living in other areas have lighter skin. The exception to this is the Inuit, who live in a place with little sunlight, but have dark skin because they eat a lot of fish and have enough vitamin D.

Evolution has given us a rainbow of skin colors. Humans have always had melanin to determine our skin color. What has changed through history is the environment where we have lived. This has in turn changed our melanin production, and eventually, skin color.
