1．When I was a child，I hoped to live in the city．I think I would be happy there．
Now I am living in a city，but I miss my home in countryside．There the air is clean or the mountains are green．Unfortunately，on the development of industrialization，the environment has been polluted．Lots of studies have been shown that global warming has already become a very seriously problem．The airs we breathe in is getting dirtier and dirtier．Much rare animals are dying out．We must found ways to protect your environment．If we fail to do so，we'll live to regret it．

2．Tired of all the pushing in supermarkets？Fed up with waiting in endless lines to pay for what you have bought？Angry at wasting time in traffic jams only to find no parking spaces when you eventually arrive at the store？If this is you，then online shopping is the answer to your dreams of trouble-free shopping．Or is it？
   Online shopping brings its own challenges．Here are a few things to bear in mind when browsing（瀏覽） various websites．The claim made by online sites is that shopping online is a safe and secure way to make purchases．The evidence challenges this．In any case，you only have to be the victim of fraud（詐騙） once to experience all the problems that come with this form of stealing．Use only sites that have a trusted history and an excellent reputation．
   Another problem is the appearance of items in reality is often quite different from what you see on your computer screen．This might not be a problem if you are buying washing up powder but could be a major disappointment when that beautiful blue dress you ordered turns up in green．Also，product descriptions are sometimes simply untrue．Perhaps the wisest plan is to purchase items where design and color are not essential to customer satisfaction．
   Some even argue that online shopping indirectly contributes to global warming．Yes，your car can stay parked but how are online goods delivered？Often by some large vans pouring out carbon monoxide and adding to our already desperate traffic problems．You are also by now becoming increasingly irritated （使煩惱） by the fact that the delivery is late and you have wasted the leave from work you have taken to receive it!
   Without question，online shopping is here to stay and it has its benefits．However，perhaps it is not as wonderful as some of its supporters claim it to be．

（1）The author lists several questions in Para．1 to

．
A．support online shopping
B．collect answers from readers
C．show his dislike of going shopping
D．introduce the topic of the passage
（2）By what can online shoppers avoid fraud？

A．Using only trusted websites．
B．Choosing big websites．
C．Collecting shopping evidence．
D．Seeking advice from the police．
（3）The author agrees with the fact that

．
A．customers are never satisfied with products
B．online shopping is a safe way to make purchases
C．online shopping has nothing to do with global warming
D．delivery delay often makes online shoppers unhappy
（4）What is the author's attitude towards online shopping？

A．Very popular．
B．A wise choice．
C．Not trouble free．
D．A waste of time．

3．We Brits love the idea of a real Christmas tree-but not so many of us like the realities of dragging a 7 ft．Norway spruce through the house and leaving needles all over the place．
   If you count yourself among the reluctant group，then it may be time to go fake（假的）．After all，buying an artificial Christmas tree doesn't mean accepting defeat．There's a huge range of options and sizes，including pre-lit trees，which will save you the frustration of trying to string your own lights．
   Another big bonus of choosing an artificial Christmas tree is cost：artificial trees can last for decades，so they work out cheaper than paying for a real tree every year．Like now retailers（零售商） are offering great deals at the moment；at Tesco，artificial Christmas trees are 25 percent off．Meanwhile，you can take advantage of the current 3 for 2 offer at Argos to fill your house with not one，not two，but three．You may perhaps partner up with friends who are also looking to invest．
   Of course，keep your tree for years and years and it will start to pay you back in terms of carbon footprint；however，a "real" one will always have to be transported，used and dealt with every year．
   Are there any downsides？Yes．You might think you're saving the planet，but a fake tree is actually not an environmentally friendly option．Most are made in factories in Asia．They're made from metal and plastic，and many end their lives in landfills．
   Another problem with a fake tree is that it doesn't look very natural-and of course you won't get that lovely pine smell either．You'll also need to find space for storage．

（1）What does the underlined word "reluctant" in Paragraph 2 probably mean？

A．Passive．
B．Related．
C．Unwilling．
D．Supportive．
（2）Which is the benefit of buying an artificial Christmas tree？

A．Abundant choices．
B．The lovely pine smell．
C．Cheaper than a real one．
D．Free for transportation．
（3）What can we learn from the passage？

A．Fake Christmas trees are environmentally friendly．
B．British people like to drag a real Christmas tree home．
C．People need to find space to store a fake Christmas tree．
D．People may get three more if they buy two fake Christmas trees．
（4）What is the passage mainly about？

A．Different reasons for choosing fake Christmas trees．
B．Valuable suggestions on choosing fake Christmas trees．
C．Efficient ways of saving money on choosing Christmas trees．
D．Advantages and disadvantages of choosing fake Christmas trees．
