Pacific Coast Highway

If you prefer to do some driving, motor along the most picturesque portions of CaliforniaState Route 1. Start in Los Angeles and meander through worthy sites like Morrow Bay, tourthe historic Hearst Castle and do a tasting at a vineyard or two en route to San Francisco.There are plenty of places to stop along the way and there is such beautiful scenery. It’s justgorgeous and can easily be done in a week.

You will visit this place if

A you dream about basking in each other’s company during a walk.

B a sampling of blue waters and ancient sites appeals to you.

C you want to experience an animal ride.

D you long for a romantic week in a magical place.

E the ideal trip for you is aboard the ship.

F you are keen on active moving in a vehicle.

G a night in a restaurant is what you would like to experience.

H you are a real food and history gourmet.

Task 4 Read the text below. Choose from (A—H) the one that best fits each space (17—22). There are two choices you do not need to use.

BAD FOR BREATHING

New study connects pollution to several common diseases that affect the lungs and airways.Researchers have connected exposure to high levels of pollutants called polycyclic aromatichydrocarbons, or PAHs, to a greater likelihood of having asthma and allergies. Inhaling airpollutants can trigger breathing problems, (17) _________. Asthma itself can be triggered by allergies.So physicians have observed that allergies, asthma and air pollution go hand in hand.

During an asthma attack, inflammation causes the inside of small airways in the lung to swell.This narrows those passageways, (18)_________ in any given breath. This means people will havea hard time (19)_________ to breathe comfortably.Researchers have now linked a common family of air pollutants to a breakdown in cells(20) _________. It plays a role in allergies. The cells they focused on are called T-regs (short forT-regulatory cells). Normally, they help protect the body by controlling swelling (21) _________.

To probe the connection between PAHs and T-regs, Kari Nadeau of Stanford University and herco-workers looked at many different types of data. They collected blood tests, lung measurementsand other health information from more than 150 children in Fresno, (22) _________. The scientiststhe also measured PAHs in the air in and near the homes of these children. T-regsdidn’t work aswell as they should in kids living in heavily polluted areas. Children exposed to high levels of PAHalso were much more likely to have asthma.

A reducing how much air can move through them

B meeting of scientists who study allergies

C the California city with high levels of air pollution

D such as asthma

E involved in the immune system

F caused by inflammation

G used to protect against infections or toxic substances

H drawing in enough air

Task 5 Read the text below. For questions (23—32) choose the correct answer (A, B, C or D).

FLOWER POWER

Electric field around flowers may help bees find nutritious blooms.Flowers maintain small electric fields (23)_________ them. Bees can not only (24) _________thosefields, but they may also tell the insects which blooms are most likely (25)_________ a nectar reward,a team of scientists recently reported.

Flowers growing in the ground have a natural negative electric charge, notes Daniel Robert,a sensory biologist at the University of Bristol in England who worked on the new study. Their blooms(26)_________ electrons — the particles that carry negative charge — from the air to the ground.Throughout the air, positive electric charges abound, he explains. So bees, as they (27) _________,can become positively charged.

The scientists set up 30 (28) _________metal disks covered with purple plastic to resemble flowers.Half of the disks were wired to create small electric fields, and half weren’t. The disks with electricfields contained a sweet solution; the unwired ones held a bitter solution.Scientists then sent in the bees and (29) _________track of where they went. Toward the tail endof 50 visits to the «flowers», most bees had learned to find the sweet ones. Then the researchersunplugged the fake sweet flowers and tried the (30)_________ again. This time, when the fields wereoff, the bees never learned. Even after 50 visits, they found the sugar only about half the time — nobetter than if left to chance.

Robert and his (31) _________studied the electric fields of real flowers, petunias, to betterunderstand how bees and flowers might communicate. The scientists took measurements of a flowerbefore and after a charged bee approached it. The flower’s field reacted to the approaching bee witha small increase in strength. That electrical boost lingered for a little while after the bee had flownaway.

That short-lived surge may help tell a different approaching bee that all of the flower’s nectarhas just been drunk. That bee would be able to sense the change in the flower’s electric field, andmove on to find a flower full of (32) _________.Or, as Robert told Science News, the flower could signal to the bee: «I’m still pretty and smellnice, but… come back later».
