【题目】 One of the most traditional British holidays is the seaside holiday. Typically, families travel to British seaside towns.

In the late 1970s, air travel became affordable for the average family, and more and more British people started travelling abroad for their summer holidays. After all, the British weather isn’t very good, even in summer.

In the 1980s and 1990s, British young people became wealthier. They started to go abroad in groups. Once at their destination they socialised with other young people and had one long party.

British holidaying habits have begun to change, however. The UK now has a warmer climate than before, so people don’t always feel they need to go overseas. Also, the world seems a less certain place as interconnected economies (经济) rise and fall, which means that the cost of foreign holidays is less predictable than before. The domestic (国内的) tourism industry — when people go on holiday in their own country — is healthier than it has been in decades. UK newspapers have even invented a new word: a “staycation”.

In some ways, therefore, the UK has come full circle. There is now an increased appreciation among Britons for the diversity of the UK. It is not just the geography, which ranges from the flat fens (沼泽) of East Anglia to the valleys of Wales to the mountains of Scotland, which is diverse. And it is not just the diversity of climate-based activities on offer, which range from surfing in the warm southwest of England, to hillwalking and skiing in the north, it is also the diversity of the cultures in the UK that is beginning to be of interest to domestic tourists. People forget sometimes that there are different accents, languages, traditions, cuisines and peoples across all the parts of the UK.

1Why do more British people take their holidays in their own country?

A.The Internet makes them closer.

B.They are wealthier and more sociable.

C.The global climate is getting much warmer.

D.The expense on foreign holidays is unsteady.

2What does the underlined word “staycation” in Paragraph 4 refer to?

A.A vacation spent at home.B.A healthier style of living.

C.A new way to spend holiday.D.A fashionable tourism industry.

3Which is the best heading that matches Paragraph 5?

A.Flights of fancy.B.Sun, sea and sand.

C.The length and width.D.Footloose and fancy-free.

4What’s the purpose of the author in writing the passage?

A.To prove the UK has diverse scenery.

B.To show the UK starts to discover itself.

C.To tell the development of the United Kingdom.

D.To explain why the British spend holidays inland.

【题目】 One of the most critical roles forests play is relieving climate change. Trees suck enormous amounts of carbon dioxide out of the air and fix the carbon in their wood and the soil. A recent study found that planting new trees over an area the size of the US could suck away two thirds of all the carbon dioxide discharge that humans have pumped into the atmosphere.

“Without animals, it is harder for forests to absorb carbon, as tree species (种类) important for protecting the climate could be lost without animals", Susanne Winter, a program director said at the WWF.

In Africa, many of the tree species that absorb the most carbon rely on large birds and primates (灵长类动物) to eat their fruits and spread their large seeds, according to the report. Without them, those trees would have difficulty reproducing and forests would lose their best carbon-storing trees.

“Forests are our greatest natural ally in the fight against global warming, ”Winter said.“If we want to hold back the worldwide decline in biodiversity and prevent the climate crisis,s we need to protect the forests and the species living there.

Forests also filter (过滤) water-- as water makes its way to lakes or groundwater reserves, the roots and soil separate it from deposits and pollution that it collects along the way. What' s more, forests regulate the global water cycle, since trees' leaves, branches, and roots store or send out water vapor.

Climate models show that forest-cutting down in Central Africa could lead to a 15% drop in rainfall in the US Midwest, and Amazon deforestation (森林滥伐) could cut Texas rainfall by 25%.

Humans also get food, wood, and medicine from the abundance of plants and animals in forests. Worldwide, 1.6 billion people rely on forests for their livings, according to the United Nations. About 300 million people live in forests, according to WWF.

1What's the purpose of Paragraph 3?

A.To tell where the large seeds go.

B.To show the tree species in Africa.

C.To draw reader' s attention to Africa.

D.To support Susanne Winter’s opinion.

2What does the underlined word“ally" in Paragraph 4 probably mean?

A.Winner.

B.Competitor.

C.Partner.

D.Victim.

3How do forests change climate according to the passage?

A.By affecting air and water.

B.By feeding birds and animals.

C.By providing life necessities.

D.By increasing the variety of trees.

4What can be inferred from the passage?

A.Water should be filtered.

B.The more forests, the more rain.

C.Forests should be globally protected.

D.Half the carbon dioxide is sucked away by trees.
