Do you know how to plant a tree? Once you’ve chosen a tree, you’ll need to prepare your place for planting.
Planting the Tree
Dig a hole a foot deeper than and twice as wide as the root ball of the new tree. Loosen the soil at the bottom and sides of the hole, so roots will be able to easily enter the soil.
Gently remove the tree from the container and guide the tree into the hole. Build soil up and around the roots if necessary, so the tree is at the same soil level as it was originally grown.
Straighten the tree in the hole. Before you begin filling, have someone view the tree from several directions to confirm that the tree is straight. You should fill the hole with existing soil that has been mixed with rich materials. At this time you can also add bone meal and then water the tree.
Caring for the Tree
Caring for the tree once it is planted, is an important step so you should provide regular watering. Always feel the soil before watering, as over-wearing can also harm the tree. When soil is dry below the surface of the covering, it’s time to water. You will probably need to water at least once a week. Continue until mid-fall, when lower temperatures call for less-frequent watering.
When to Plant a Tree
Now that you know how to plant a tree, the next step is deciding when to plant. Spring and fall are generally the best times to plant a tree. This gives the tree time to adjusts(调整)before summer heat or winter cold arrives. In areas without cold winters, trees may be planted during the winter.

B. It isn’t very important to care for it after the tree is planted

Winslow Homer was a famous American painter. Since Art History class in college, I had always admired his works and I was lucky to see a large exhibition of his works when I was in my early 30’s. It was at this event that I bought a print of his painting, “Snap the Whip”. I had it framed and until I retired from teaching it always hung in my classroom.

During my last year of teaching, there was a young woman in her first year of teaching right next door to me and we got to be good friends. She had been an art student before switching to education. Her eyes were drawn immediately to this print when she entered my room. So on my last day of teaching, after the students had left, I took the painting off the wall and walked next door and gave it to her.
She was really surprised, but very pleased to have it. I was pleased that she liked it and all the students she would have would treasure(珍爱)it as much as I had. We found the perfect place for it on one of her walls and hung it together. Thank you for bringing back this wonderful memory for me.

More than 135,000 UK drinkers will die from cancer caused by alcohol(酒精)by the year 2035, researchers say. Drinking too much will cause 7,100 cancer deaths a year by 2035, a rise of 13 percent on the present rate. A study by Sheffield University and Cancer Research UK shows that alcohol will cost the NHS(National Health Service) ￡53billion over the next ten years including ￡2 billion on cancer.
Although alcohol is known to cause many types of cancer including breast and throat most people don’t realize the relation between alcohol and cancer. A survey of 2,100 Britons by the researchers earlier this year found nine in ten did not associate drinking with cancer. The researchers used a computer model to work out the numbers of alcohol-related cancer deaths, hospital admissions(入院)and total costs to NHS over the next 20 years.
The study shows that a fifth of men and 1 in 10 women have alcohol every day---and many of these are middle-aged and middle class. Researchers are very worried about this group as they believe cancer may be caused by drinking over long periods. The study shows that even if the expense stays as it is, alcohol-related cancer deaths will rise from 6,299 in 2015 to 7,097 in 2034. Alcohol will lead to 891, 299 hospital admissions, up from 802, 118 in 2015, and 65, 005 will be caused by cancer.
Earlier this year Chief Medical Officer Dame Sally Davies studied carefully the alcohol guidelines(指导方针)for the first time in thirty years. She told people there was no safe level of drinking and advised them to drink no more than 14 units a week. But researchers say this guidance isn’t enough and want the government to increase a little price per unit of alcohol.
1.What can we learn from the text?
A. Fewer people will die of cancer in the future
B. Alcohol will be the only cause of cancer deaths
C. More and more people will get rid of the habit of drinking
D. The computer model can offer researchers useful numbers
2.What does the underlined word “associate” in Paragraph 2 probably mean?
A. Share B. Compare
C. Connect D. Replace
3.The researchers hope the government can __________.
A. raise the price of alcohol properly
B. remove the nation’s drinking habit
C. improve middle-aged persons’ income
D. provide fund for National Health Service
4.What may be the best title for the text?
A. People Having Alcohol Must Suffer from Cancer
B. All People Have Known Alcohol May Cause Cancer
C. Researchers Are Trying to Discover the New Causes of Cancer
D. Alcohol will Have Worse Effects on British People over the Coming Years
