Sunday, October 5
Clear, 69°F
My wife, Eleanor, and I took the train from Paris to Strasbourg, where we were met by our driver and guide, and the minibus which goes along with the boat. We stopped off in Barn for an hour on the way. Then we were taken to Nancy where the boat was kept.
After the other passengers arrived, we had our first dinner on the boat. After dinner we walked into downtown Nancy, a village with a large square and wooden houses.
Monday, October 6
Rained last night, cloudy in the morning, 69°F
We spent about two hours in Nancy, then sailed on the Canal de la Marne au Rhine. Kind of a lazy day, eating breakfast, lunch, and dinner. After dinner we watched a tape on Baccarat, where we will visit tomorrow.
It was pleasant to sit out on deck (甲板) and watch the scenery go by at about 3 mph.
Tuesday, October 7
Light rain, 64°F
This morning we drove over to Baccarat and toured its museum and the church, which has this unbelievable lamp that is going on a world tour the next day. We did lots of shopping, then walked across the bridge to see a very, very modern Catholic church with special Beccarat windows.
We drove to the top of the Voges Mountains and started down the eastern side, Later we drove to Sorrenbourg to see the 13th century church at the Cordeliers. It contains the largest window by Marc Chagall – 24 feet wide by 40 feet high.
Wednesday, October 8
Cloudy, 65°F
Today we sailed from Schneckenbush to Saverne. We went through two caves, an extremely unusual part of the journey. This river scenery is very different. We were in a mountain valley with grassland on one side and a forest beginning to show some color on the other.
Thursday, October 9
Cloudy, 66°F
Our dependable minibus was waiting to load the luggage and take us to the hotel where everyone went their separate ways. Our boating days are over until next time.

The Smog（烟雾）
For over a month,Indonesia was in crisis.Forest fires raged out of control as the
country suffered its worst drought for 50 years.Smoke from the fires mixed with sunlight and
hot dry air to form a cloud of smog.This pollution quickly spread and within days it was
hanging over neighbouring countries including Malaysia,Singapore and Thailand.
When the smoke combined with pollution from factories and cars,it soon became
poisonous（有毒的）.Dangerous amounts of CO became trapped under the smog and
pollution levels rose. People wheezed（喘息）and coughed as they left the house and their
eyes watered immediately.
The smog made it impossible to see across streets and whole cities disappeared as
grey soot（烟灰） covered everything. In some areas, water was hosed（用胶管浇）from
high-rise city buildings to try and break up the smog.
Finally,heavy rains,which came in November,put out the fires and cleared the air.
But the environmental costs and health problems will remain.Many people from South-
Eastern Asian cities already suffer from breathing huge amounts of car exhaust fumes（汽车
排放的废气）and factory pollution. Breathing problems could well increase and many non-
sufferers may have difficulties for the first time.Wildlife has suffered too.In lowland
forests,elephants,deer,and tigers have been driven out of their homes by smog.
But smog is not just an Asian problem.In fact,the word was first used in London in
1 905 to describe the mixture of smoke and thick fog.Fog often hung over the capital.
Sometimes the smog was so thick and poisonous that people were killed by breathing
problems or in accidents.About 4, 000 Londoners died within five days as a result of thick
smog in 1952.Indonesia was in crisis because of the drought.

第7题：
Forests give us shade,quiet and one of the larder callenges in the fight against climate change.Even as we humans count on forests to soak up a good share of the carbon dioxide we produce,we are threatening their ability to do so.The climate change we are hastening could one day leave us with forests that emit more carbon than they absorb.Thankfully,there is a way out of this trap-but it involves striking a subtle balance.Helping forests flourish as valuable“carbon sinks”long into the future may require reducing their capacity to absorb carbon now.California is leading the way,as it does on so many climate efforts,in figuring out the details.The state’s proposed Forest Carbon Plan aims to double efforts to thin out young trees and clear brush in parts of the forest.This temporarily lowers carbon-carrying capacity.But the remaining trees draw a greater share of the available moisture,so they grow and thrive,restoring the forest’s capacity to pull carbon from the air.Healthy trees are also better able to fend off insects.The landscape is rendered less easily burnable.Even in the event of a fine,fewer trees are consumed.The need for such planning is increasingly urgent.Already,since 2010,drought and insects have killed over 100 million trees in California,most of them in 2016 alone,and wildfires have burned hundreds of thousands of acres.California plans to treat 35,000 acres of forest a year by 2020,and 60,000 by 2030-financed from the proceeds of the state’s emissions-permit auctions.That’s only a small share of the total acreage that could benefit,about half a million acres in all,so it will be vital to prioritize areas at greatest risk of fire or drought.The strategy also aims to ensure that carbon in woody material removed from the forests is locked away in the form of solid lumber or burned as biofuel in vehicles that would otherwise run on fossil fuels.New research on transportation biofuels is already under way.State governments are well accustomed to managing forests,but traditionally they’ve focused on wildlife,watersheds and opportunities for recreation.Only recently have they come to see the vital part forests will have to play in storing carbon.California’s plan,which is expected to be finalized by the governor next year,should serve as a model.California’s Forest Carbon Plan endeavors to_______.《》（）A.cultivate more drought-resistant trees
B.reduce the density of some of its forests
C.find more effective ways to kill insects
D.restore its forests quickly after wildfires答案：B解析：根据题干California’s Forest Carbon Plan endeavors to_______.定位到原文三段第一句The state’s proposed Forest Carbon Plan aims to double efforts to thin out young trees and clear brush in parts of the forest.该句大意为森林碳计划的目的是大力减少小树并在森林的部分地方除掉灌木丛。B选项为减少他的森林的密度，因此B选项是正确选项。 -
第8题：
Very few of our birds stay with us the year round.Some come to us in the winter from the cold?north.Others come from the south to spend the summer with us.How do they know the way?Suppose?you were told to find your way to a place hundreds of miles away,do you think you could do it?
Yet birds travel over mountains,forests,lakes and even across the oceans,and do not stray from?the path.They find their way back in the spring to the same orchard（果园）and the very trees where?they nested the summer before.
It is wonderful how quickly birds travel such long distances from their summer homes to their?winter ones.Some birds have been known to fly hundreds of miles in a day.But others travel much?more slowly.
Why do birds undertake these long journeys twice a year?Perhaps cold weather and lack of?food drive them from us in the autumn,but we cannot tell why they leave the sunny south to come?back to us in the spring.We know only that many of them like to make their nests and rear their?young in the north.
We are sorry to see them go,but we know that when winter is over they will come back to us.
In which season do we have most birds to stay with us?A.In spring.
B.In summer.
C.In winter.
