Task type: multiple choice
Read a story about dandelions. Complete statements (1-7) below the text by choosing the best
answer (a, b, c, d). Write your answers in the boxes below the task.
DANDELIONS
Some people think dandelions are useful plants.
Other people think they are weeds. Many people don't
want dandelions to grow on their lawns. They want neat
green grass without flowers and leaves in it. These people
work hard to pull dandelions out of their lawns. Some even
try to get rid of dandelions with weed killer.
It's pretty hard to kill dandelions. They are very
strong plants. Some of the leaves stay green in winter,
even if the weather gets quite cold. Dandelions begin to
bloom in the early spring. As soon as warm weather comes, they begin to have bright yellow
flowers. The flowers close up tight at night. When the sun slimes, they open up again.
Dandelion plants can be quite useful. The leaves can be eaten in salad. They also can be
cooked and eaten as greens. Some people even make dandelion wine.
