Whether you like it or not, we are currently in a season of economic uncertainty. A couple of years back, everything seemed fine. Many did not
see the handwriting on the wall. Most of those who saw it talked about it and did nothing about it. When the roof came crashing, it affected those
who were clueless and those who had a clue and did nothing about it the same way. The wise foresees trouble and takes evasive action while the fool
runs smack into it.
In business and life generally, things go up and down. Nothing stays the same forever. Markets go up and down. Business is always evolving as
new technologies or trends become mainstream. If everything is going well with our business, it does not mean we can just sit back and relax. Instead,
we need to look beyond today’s certainty to when something new comes up and disrupts our business. We need to be prepared for that eventuality, or
we would be ambushed by it.
A smart business invests in the next technology rather than wait to be put out of business. If we want our business to last long, we need to see
beyond today to tomorrow’s uncertainties. We have to look at what may or is going to happen next in our area of business, and position ourselves to
benefit from it. If, unfortunately, you are already a victim of short sightedness and are struggling to get back on your feet, you may want to remember
and learn from the lesson after what you have gone through.

(C) looked down upon (D) found fault with
Mushrooms are popping up in odd places all over the supermarket, from coffee and kombucha to snack bars. That’s because the humble fungus
is nutritionally impressive: add it to any dish and you’ll impart loads of savory, meaty flavor for very few calories. Six white mushrooms clock in at a
mere 28 calories. Mushrooms also deliver nutrients that many people lack, like potassium, which keeps blood pressure in check: a cup of white
mushrooms has nearly 10% of your daily recommended target (4,700 mg), a goal only 2% of Americans meet. Mushrooms are brimming with phytochemicals, antioxidants and a fiber called beta-glucan, all of which have anti-inflammatory properties.
That means they can protect you from a number of diseases. A 2017 study found fungi to be the best source of two disease-fighting antioxidants,
ergothioneine and glutathione. Low levels of the latter have been linked with higher risks of heart disease, diabetes and cancer.
The nutritional merits of some of the latest mushroom-enhanced products—like a chocolate drink spiked with mushroom extract—are less clear.
But mushrooms are increasingly being used to replace red meat. The fast-food chain Sonic Drive-In briefly introduced a patty made with 75% beef
and 25% cooked mushrooms, resulting in a burger with less saturated fat and calories. Another recent launch: mushroom jerky made with shiitake
stems, which has less protein but more fiber than meat versions. When making your own mushroom creations, shop for dry packages at the supermarket that are free of condensation. Store the mushrooms in a
refrigerator in a sealed paper bag, and prep them by wiping them down immediately before cooking.
Mushroom types vary by their antioxidant concentrations. (Meaty porcinis, for example, are one of the most antioxidant-rich fungi.) But you
can enhance the nutritional prowess of nearly any variety just by putting a pack of mushrooms in the sun. Mushrooms use sunlight to make vitamin D,
yet most are grown in the dark. A cup of white mushrooms contains little vitamin D, but one study found that putting them in natural sunlight for 30
minutes grew the vitamin D content between 150 IU and 600 IU per cup, or 25% to 100% of your recommended daily dose. If you chop them up first,
you’ll increase sun contact and maximize vitamin D production. You also can buy vitamin D-enhanced mushrooms at certain grocery stores.
【題組】47. What is the merit of mushrooms according to this passage?
(A) They can replace red meat because of their meaty flavor and glutathione.
(B) The mushroom-enhanced products help to prevent a number of diseases.
(C) They contain potassium, phytochemicals, antioxidants, and beta-glucan.
(D) They are low in calories and sodium, but high in fiber and saturated fat.
