16．Organic food（有机食品） is very safe and healthy not just for our body but also the environment．It is free from harmful chemicals that may affect us．It also strengthens our immune system（免疫系统）．However，compared with conventional food，which is more common，organic food is much more expensive．There are a lot of reasons．Growing organic food takes a lot of effort and money and shops selling organic food are using the popularity of organic food to sell it at a much higher price．
The number of organic crops is smaller than that of conventional crops．The production costs are very high in organic farming．Many farmers don't use herbicides （除草剂）or pesticides （杀虫剂）so they have to get rid of the weeds and pests in the fields all by hand，which adds to the cost of organic food．
Also，conventional agriculture（农业） is heavily supported by the government in terms of taxes，while organic farming gets no help from the government at all．What's more，the farmers can't use sewage sludge（下水道污泥） and chemical fertilizers（肥料），which are cheap to buy．
Another reason is that the demand is much higher than the supply．While there are many people who are trying organic food，there are only a limited number of farmers who produce it．The output （产量） of organic food is low while the transport and packaging costs are the same，which lead to its higher price．
Organic farming requires a lot of things that are not needed in conventional farming．But if the demand becomes high enough，the government might one day help organic farming to lessen the costs．

29．Which of the following is the closest in meaning to the underlined word"conventional"in paragraph 1？C
A．Simple  B．Real  C．Usual  D．Similar．

A．organic farmers use more expensive materials．
B．a large number of farmers produce organic food．
C．the government will soon help organic farming．
D．organic farmers also use herbicides or pesticides．

A．How to grow organic food．
B．The benefits of organic food．
C．Organic food and the environment．

8．Forgiveness
To forgive is a virtue，but no one has ever said it is easy．When someone has deeply hurt you，it can be extremely difficult to let go of your hate．However，forgiveness is possible，and it can be surprisingly beneficial to your physical and mental health．People who forgive show less sadness，anger and stress and more hopefulness，according to a recent research．
